Abstract
Konjac flour, mainly obtained and purified from the tubers ofAmorphophallus konjac C. Koch, yields a high molecular weight (Mw) and viscous hydrocolloidal polysaccharide: konjac glucomannan (KGM). KGM has been widely applied in the food industry as a thickening and gelation agent as a result of its unique colloidal properties of effective viscosity enhancement and thermal-irreversible gelling. This review first narrates the typical commercial KGM source species, the industrial production, and the purification process of KGM flour. The structural information on native KGM, gelation mechanisms of alkali-induced deacetylated KGM (Da-KGM) hydrogel, progress on degraded KGM derivatives, cryoprotection effect, and colloidal nutrition are highlighted. Finally, the regulatory requirements of konjac flour and KGM among different countries are briefly introduced. The fine structure and physicochemical properties of KGM can be regulated in a great range via the deacetylation or degradation reaction. Here, the relationship between the physicochemical properties, such as viscosity, solubility, gelation, and nutritional effects, of native KGM, Da-KGM, and degraded KGM derivatives was preliminary established, which would provide theoretical guidance for designing KGM-based products with certain nutritional needs.

Crosstalk during the Carbon-Nitrogen Cycle That Interlinks the Biosynthesis, Mobilization and Accumulation of Seed Storage Reserves. Int J Mol Sci 2021; 22:ijms222112032.

Abstract
Carbohydrates are the major storage reserves in seeds, and they are produced and accumulated in specific tissues during the growth and development of a plant. The storage products are hydrolyzed into a mobile form, and they are then translocated to the developing tissue following seed germination, thereby ensuring new plant formation and seedling vigor. The utilization of seed reserves is an important characteristic of seed quality. This review focuses on the seed storage reserve composition, source–sink relations and partitioning of the major transported carbohydrate form, i.e., sucrose, into different reserves through sucrolytic processes, biosynthetic pathways, interchanging levels during mobilization and crosstalk based on vital biochemical pathways that interlink the carbon and nitrogen cycles. Seed storage reserves are important due to their nutritional value; therefore, novel approaches to augmenting the targeted storage reserve are also discussed.

Abstract
As the first line of defense against intestinal bacteria and toxins, intestinal epithelial cells are always exposed to bacteria or lipopolysaccharide (LPS), whereas pathogenic bacteria or LPS can cause intestinal epithelial cell damage. Previous studies have shown that konjac mannan oligosaccharides (KMOS) have a positive effect on maintaining intestinal integrity, and Bacillus subtilis (BS) can promote the barrier effect of the intestine. However, it is still unknown whether KMOS and BS have a synergistic protective effect on the intestines. In this study, we used the LPS-induced Caco-2 cell injury model and mouse intestinal injury model to study the synergistic effects of KMOS and BS. Compared with KMOS or BS alone, co-treatment with KMOS and BS significantly enhanced the activity and antioxidant capacity of Caco-2 cell, protected mouse liver and ileum from LPS-induced oxidative damage, and repaired tight junction and mucus barrier damage by up-regulating the expression of Claudin-1, ZO-1 and MUC-2. Our results demonstrate that the combination of KMOS and BS has a synergistic repair effect on inflammatory and oxidative damage of Caco-2 cells and aIIeviates LPS-induced acute intestinal injury in mice.

Abstract
SCOPE Konjac glucomannan oligosaccharides (KMOS) are prebiotics and may improve intestinal immunity through modulation of macrophage function. However, the underlying molecular mechanisms were unclear. METHODS AND RESULTS Using a mouse model of dextran sulfated sodium (DSS)-induced acute colitis, the study demonstrates here that KMOS (400 mg-1 kg-1 d-1 ) can ameliorate intestinal inflammation in a macrophage dependent manner. Oral exposure to KMOS prevents DSS-induced intestinal pathology, improves epithelial integrity, and decreases accumulation of colonic inflammatory leukocytes and cytokines. The therapeutic effects of KMOS are dependent on the function of macrophages, as depletion of macrophages abolished the effects. In colonic lamina propria of DSS-treated mice, as well as in vitro culture of bone marrow derived macrophages (BMDMs), KMOS skews reprogramming of classically activated macrophages (CAM/M1) into alternatively activated macrophages (AAM/M2). The study further determines that the activation of SIGNR1/phospho-c-Raf (S338)/phospho-p65 (S276)/acetyl-p65 (K310) pathway is responsible for KMOS-induced AAM/M2 polarization. Blockage of SIGNR1 abolishes KMOS-induced AAM/M2 polarization of activated macrophages, expression of phospho-p65 (S276) in colonic macrophages, and alleviation of DSS-induced colitis in mice, suggesting that SIGNR1 is critical for macrophage responses to KMOS. CONCLUSIONS This study reveals a SIGNR1-mediated macrophage-dependent pathway that supports regulatory function of KMOS in host immunity and intestinal homeostasis.

Abstract
Purpose of Review The aim of this review is to summarize the available clinical efficacy and safety data related to the most studied and used lipid-lowering nutraceuticals. Recent Findings A growing number of meta-analyses of randomized clinical trials supports the effectiveness and tolerability of some lipid-lowering nutraceuticals such as red yeast rice, plant sterols and stanols, soluble fibers, berberine, artichoke extracts, bergamot polyphenol fraction, garlic, green tea, and spiruline. No significant safety concern has been raised for the use of such products. Association of more lipid-lowering nutraceuticals and of some nutraceuticals with lipid-lowering drugs has been tested as well. Summary Current evidence suggests that some clinically tested lipid-lowering nutraceuticals could be safely used to improve plasma lipid levels in subjects affected by mild-to-moderate dyslipidaemia with low cardiovascular risk.

Abstract
Few medically-approved excipients are available for formulation strategies to endow microcarriers with improved performance in lung drug targeting. Konjac glucomannan (KGM) is a novel, biocompatible material, comprising mannose units potentially inducing macrophage uptake for the treatment of macrophage-mediated diseases. This work investigated spray-dried KGM microparticles as inhalable carriers of model antitubercular drugs, isoniazid (INH) and rifabutin (RFB). The polymer was characterised and different polymer/drug ratios tested in the production of microparticles for which respirability was assessed in vitro. The swelling of KGM microparticles and release of drugs in simulated lung fluid were characterised and the biodegradability in presence of β-mannosidase, a lung hydrolase, determined. KGM microparticles were drug loaded with 66-91% association efficiency and had aerodynamic diameter around 3 µm, which enables deep lung penetration. The microparticles swelled upon liquid contact by 40-50% but underwent size reduction (>62% in 90 min) in presence of β-mannosidase, indicating biodegradability. Finally, drug release was tested showing slower release of RFB compared with INH but complete release of both within 24 h. This work identifies KGM as a biodegradable polymer of natural origin that can be engineered to encapsulate and release drugs in respirable microparticles with physical and chemical macrophage-targeting properties.

Abstract
In a recent study, we showed that konjac glucomannan (KGM) inhibits rice gruel-induced postprandial increases in plasma glucose and insulin levels. To extend this research, we investigated the effects of KGM addition to rice gruel on pre- and postprandial concentrations of circulating lipoprotein lipase (LPL), glycosylphosphatidylinositol-anchored high-density lipoprotein-binding protein 1 (GPIHBP1), hepatic triglyceride lipase (HTGL), free fatty acids (FFA), and triglycerides (TG). A total of 13 Japanese men, without diabetes, dyslipidemia, or gastrointestinal diseases, interchangeably ingested rice gruel containing no KGM (0%G), rice gruel supplemented with 0.4% KGM (0.4%G), and rice gruel supplemented with 0.8% KGM (0.8%G), every Sunday for 3 weeks. Blood samples were obtained at baseline and at 30, 60, and 120 min after ingestion to measure the abovementioned lipid parameters. Lipid parameters showed small, but significant, changes. Significant reductions were found in circulating FFA levels among all participants. Circulating TG levels significantly declined at 30 min and then remained nearly constant in the 0.8%G group but exhibited no significant difference in the 0%G and 0.4%G groups. Although circulating levels of LPL and GPIHBP1 significantly decreased in the 0%G and 0.4%G groups, they increased at 120 min in the 0.8%G group. Participants in the 0%G and 0.4%G groups showed significant decreases in circulating HTGL levels, which was not observed in the 0.8%G group. Our results demonstrate the novel pleiotropic effects of KGM. Supplementation of rice gruel with KGM powder led to TG reduction accompanied by LPL and GPIHBP1 elevation and HTGL stabilization, thereby attenuating TG metabolism.

Abstract
BACKGROUND The carbohydrate polymers that encapsulate plants cells have benefited humans for centuries and have valuable biotechnological uses. In the past 5 years, exciting possibilities have emerged in the engineering of polysaccharide-based biomaterials. Despite impressive advances on bacterial cellulose-based hydrogels, comparatively little is known about how plant hemicelluloses can be reconstituted and modulated in cells suitable for biotechnological purposes. RESULTS Here, we assembled cellulose synthase-like A (CSLA) enzymes using an optimized Pichia pastoris platform to produce tunable heteromannan (HM) polysaccharides in yeast. By swapping the domains of plant mannan and glucomannan synthases, we engineered chimeric CSLA proteins that made β-1,4-linked mannan in quantities surpassing those of the native enzymes while minimizing the burden on yeast growth. Prolonged expression of a glucomannan synthase from Amorphophallus konjac was toxic to yeast cells: reducing biomass accumulation and ultimately leading to compromised cell viability. However, an engineered glucomannan synthase as well as CSLA pure mannan synthases and a CSLC glucan synthase did not inhibit growth. Interestingly, Pichia cell size could be increased or decreased depending on the composition of the CSLA protein sequence. HM yield and glucose incorporation could be further increased by co-expressing chimeric CSLA proteins with a MANNAN-SYNTHESIS-RELATED (MSR) co-factor from Arabidopsis thaliana. CONCLUSION The results provide novel routes for the engineering of polysaccharide-based biomaterials that are needed for a sustainable bioeconomy. The characterization of chimeric cellulose synthase-like enzymes in yeast offers an exciting avenue to produce plant polysaccharides in a tunable manner. Furthermore, cells modified with non-toxic plant polysaccharides such as β-mannan offer a modular chassis to produce and encapsulate sensitive cargo such as therapeutic proteins.

Abstract
: Cardiovascular diseases (CVDs) are the main cause of mortality worldwide. Risk factors of CVD can be classified into modifiable (smoking, hypertension, diabetes, hypercholesterolemia) through lifestyle changes or taking drug therapy and not modifiable (age, ethnicity, sex and family history). Elevated total cholesterol (TC) and low-density lipoprotein-cholesterol (LDL-C) levels have a lead role in the development of coronary heart disease (CHD), while high levels of high-density lipoprotein-cholesterol (HDL-C) seem to have a protective role.The current treatment for dyslipidemia consists of lifestyle modification or drug therapy even if not pharmacological treatment should be always considered in addition to lipid-lowering medications.The use of lipid-lowering nutraceuticals alone or in association with drug therapy may be considered when the atherogenic cholesterol goal was not achieved.These substances can be classified according to their mechanisms of action into natural inhibitors of intestinal cholesterol absorption, inhibitors of hepatic cholesterol synthesis and enhancers of the excretion of LDL-C. Nevertheless, many of them are characterized by mixed or unclear mechanisms of action.The use of these nutraceuticals is suggested in individuals with borderline lipid profile levels or with drug intolerance, but cannot replace standard lipid-lowering treatment in patients at high, or very high CVD risk.Nutraceuticals can also have vascular effects, including improvement in endothelial dysfunction and arterial stiffness, as well as antioxidative properties. Moreover, epidemiological and clinical studies reported that in patients intolerant of statins, many nutraceuticals with demonstrated hypolipidemic effect are well tolerated.

Abstract
Konjac glucomannan oligosaccharide has attracted much attention due to its broad biological activities. Specific glucomannan degrading enzymes are effective tools for the production of oligosaccharides from konjac glucomannan. However, there are still few reports of commercial enzymes that can specifically degrade konjac glucomannan. The gene ppgluB encoding a glucomannanase consisting of 553 amino acids (61.5 kDa) from Paenibacillus polymyxa 3-3 was cloned and heterologous expressed in Escherichia coli BL21 (DE3). The recombinant PpGluB showed high specificity for the degradation of konjac glucomannan. Moreover, the hydrolytic products of PpGluB degrade konjac glucomannan were a series of oligosaccharides with degrees of polymerisation of 2-12. Furthermore, the biochemical properties indicated that PpGluB is the optimal active at 45 to 55 °C and pH 5.0-6.0, and shows highly pH stability over a very broad pH range. The present characteristics indicated that PpGluB is a potential tool to be used to produce oligosaccharides from konjac glucomannan.

Abstract
A structurally defined konjac glucomannan oligosaccharide (KGMOS) with a relatively high molecular weight and narrow molecular weight distribution (molecular weight ranging from 3000 to 4000 Da, degree of polymerization (dp) 8-11) was prepared from native konjac glucomannan (KGM), and the beneficial effects and molecular mechanisms of KGMOS on colonic functions were investigated in C57BL/6 mice. The results are the first to reveal that KGMOS regulated intestinal microflora composition to facilitate the production of colonic butyrate. Elevated butyrate production further increased the acetylation of histone proteins H3 and H4 and thus enhanced the transcription of the major colonic mucin gene Muc2 and the secretion of mucin elements, which represents a new molecular mechanism of KGM oligosaccharide consumption. The findings indicate that KGM oligosaccharides with specific molecular sizes have highly desirable functional properties and potentially could improve gut health by promoting the barrier function of the colonic mucosa.

Abstract
The objective of this study was to develop a new hydrophobic film based on konjac glucomannan and kappa-carrageenan (KGM-KC) incorporating camellia oil (CO) (2, 4, and 6 %). CO was directly emulsified as a dispersed phase into KGM-KC matrix. The physical, structural, and water barrier properties of the film were studied. The results of Fourier transform infrared and scanning electron microscopy suggested that CO was successfully distributed in KGM-KC matrix by emulsification. Contact angle of the film indicated that addition of CO increased the hydrophobicity and water-resistance properties of film, which corresponding to the moisture content, total soluble mass, water vapor permeability, water vapor adsorption kinetics and water vapor adsorption isotherms. Addition of CO by emulsification improved thermal stability of film, optical properties, and mechanical properties. In conclusion, the incorporation of CO by emulsification is an effective and promising pathway to improve the properties of polysaccharide-based film.

Abstract
The volatile components of essential oil (EO), SPME, and SPME of solvent extracts ( n -hexane, methanol, and water) obtained from fresh Serapias orientalis subsp. orientalis ( Soo ) were analyzed by GC-FID/MS. EO of Soo gave 11 compounds in the percentage of 99.97%; capronaldehyde (37.01%), 2-( E )-hexenal (23.19%), and n -nonanal (19.05%) were found to be major constituents. SPME GC-FID/MS analyses of fresh plant and solvent extracts of Soo revealed 7, 12, 7, and 4 compounds within the range of 99.7% to 99.9%. Limonene (76.5%, 41.7%, and 61.3%) was the major compound in SPMEs of the n -hexane and methanol extracts. α -Methoxy- p -cresol (52.9%) was the main component in its water extract. The antimicrobial activity of EO and the solvent extracts of Soo were screened against 9microorganisms. EO showed the best activity against Mycobacterium smegmatis , with 79.5 µg/mL MIC value. The n -hexane, methanol, and water extracts were the most active against the Staphylococcus aureus within the range of 81.25-125.0 µg/mL (MIC). IC 50 values for the lipase enzyme inhibitory activity of EO and solvent extracts ( n -hexane, methanol, and water) were determined to be 59.87 µg/mL, 64.03 µg/mL, 101.91 µg/mL, and 121.24 µg/mL, respectively.

Abstract
The purpose of this study was to determine the production of sugars from ginseng residues treated with laccase. Laccase was used to degrade lignin from ginseng residues in order to increase the yield of sugars. Reaction conditions, including solid loading, pH, enzyme concentration, incubation temperature, and incubation time, were investigated and optimized. The results showed that the optimum conditions were 20% of solid loading (w/v), pH 7, 300 IU/ml, temperature of 40 °C and incubation time of 6 h. The minimum residual lignin obtained was 59.89%. The results also showed that 56.58% sugars including 12.04% water soluble polysaccharides (WSP), 16.24% water insoluble polysaccharides (WIP) and 5.08% reducing sugar were afforded from delignify substance. Chemical characters of these sugars were analyzed. Pretreat of laccase delignification for sugars production is expected to be applied to other herbal residues.

Abstract
has attracted tremendous interest because of its high contents of glucomannan and starch. Very few genes regulating glucomannan and starch were reported in Amorphophallus. In this study, an ADP-glucose pyrophosphorylase (AGP) gene that plays a significant role in plant starch synthesis was cloned from Amorphophallus muelleri. It was shown that it encoded a predicted protein containing a conserved plant ADP-Glucose-PP repeat domain and seven potential ligand-binding sites. The real-time quantitative PCR showed that AmAGP was most abundant in tubers, and it was positively correlated with starch content. Additionally, its influencers about temperature and exogenous plant hormone were also discussed, showing that AmAGP expressed highly in tubers under treatments using 25°C and IAA. Furthermore, starch content was closely related to AmAGP expression level, suggesting that AmAGP was involved in the regulation of starch synthesis in A. muelleri. Therefore, identifying the sequence of AmAGP and its expression pattern during tuber enlarging and the changes of its transcript levels in response to temperature and plant hormones would contribute to a better understanding of starch synthesis, and also providing a reference information for future preferable breeding for obtaining more starch or more glucomannan in Amorphophallus.

Abstract
The heterogeneous sulfoethylation of cellulose, xylan, α-1,3-glucan, glucomannan, pullulan, curdlan, galactoglucomannan, and agarose was studied using sodium vinylsulfonate (NaVS) as reagent in presence of sodium hydroxide and iso-propanol (i-PrOH) as slurry medium. The influence of the concentration of polymer, water, and NaOH (solid or aqueous solution) on the degree of substitution (DS) was investigated. The sulfoethylation rendered the polysaccharides studied water-soluble. Sulfoethylation of heteropolysaccharides yielded products with higher DS compared to the conversion of homopolysaccharides. Structure characterization was carried out by means of 13C-NMR spectroscopy.

Abstract
The aim of this study was to evaluate the hypoglycemic and antioxidant potential of konjac in vitro and in vivo. Glucose diffusion and enzymatic starch digestion of konjac were assayed using α-amylase and α-glucosidase. Oral glucose tolerance test (OGTT) and oral starch tolerance test (OSTT) were performed at dose of 102 mg/Kg of body weight (equivalent to 1 g/meal in humans). Additionally, the antioxidant activity of konjac was evaluated through inhibition of lipid peroxidation. The konjac decreased glucose diffusion by 36% and 19% compared with the negative and positive controls, respectively. Additionally, konjac inhibited α-amylase and α-glucosidase activities by 14% and 90%, respectively. After OSTT, group treated with konjac showed significant lower glucose levels compared with control group (p = .03). Finally, konjac reduced lipid peroxidation in human plasma (93%) compared with the negative control. Our results suggest that konjac exhibits hypoglycemic and antioxidant activities in vitro and in vivo. PRACTICAL APPLICATIONS: Because the use of herbal products have emerged as an attractive therapeutic option for chronic diseases, konjac administration may be an adjuvant for the treatment of type 2 diabetes.

Abstract
The multi-drug resistance (MDR) of cancer cells, including 5-fluorouracil (5-FU) resistance, has been a serious problem for patients with cancer. The present study aimed to investigate the reversal effects of konjac glucomannan on multi-drug resistance of HepG2/5-FU cells. In the present study, MTT assay was used to investigate the effects of 5-FU and konjac glucomannan (KGM) on the viability of HepG2/5-FU cells. Reverse transcription-quantitative PCR and western blotting were performed to determine the effects of 5-FU and KGM on the expression of MDR-associated genes including MDR1 and P-glycoprotein 1 (P-gp 1), and to analyze the effects of 5-FU and KGM on the levels of cell proliferation-related genes, including cyclin A, cyclin B1 and CDK2, and apoptosis-related genes, including caspase-3, Bax and BCL-2. Annexin V/propidium iodide staining was performed to determine the apoptotic rate of HepG2/5-FU. Furthermore, the xenograft tumor model was established in nude mice to investigate the in vivo tumor growth by detecting tumor size, volume and tumor weight. KGM significantly decreased the viability of HepG2/5-FU cells in the presence of 5-FU. KGM downregulated the mRNA and protein expression of MDR and P-gp, and inhibited the mRNA and protein expression of cyclin A, cyclin B1 and CDK2. In addition, KGM significantly suppressed BCL-2 expression and increased the expression of cleaved caspase-3 and Bax, resulting in a higher apoptotic rate of HepG2/5-FU cells. Furthermore, KGM suppressed AKT phosphorylation and upregulated p53 expression. Notably, KGM significantly inhibited the growth of HepG2/5-FU in nude mice. KGM may be a promising agent against the resistance of HepG2/5-FU cells to 5-FU by suppressing AKT signaling and increasing p53 expression.

Abstract
OBJECTIVE Given the association between diabetes suppression and inhibition of diet-induced elevation in glucose and insulin, we investigated the effects of adding glucomannan to rice gruel on pre- and postprandial glucose and insulin concentrations. METHODS A total of 25 Japanese subjects without a history of diabetes or gastrointestinal disease (all males; aged 37-60 years; body mass index 20.4-31.6) participated in this study. Subjects received a 75-g oral glucose tolerance test (75gOGTT) and rice gruel containing 0, 0.4, or 0.8% of glucomannan. Blood samples were then obtained at preload and at 30, 60, and 120 min after receiving 75 g of glucose or rice gruel with or without glucomannan. RESULTS After the 75gOGTT, 8 subjects had normal glucose tolerance (NGT), whereas 17 showed a borderline pattern. Moreover, our data showed that greater amounts of glucomannan promoted lesser 30-min postload plasma glucose and insulin levels, with differences being larger in the borderline group than in the NGT group. CONCLUSIONS Glucomannan dose-dependently inhibited the rice gruel-induced increase in 30-min postprandial plasma glucose and insulin levels. Furthermore, greater inhibitory effects on glucose and insulin elevation were observed in the borderline group than in the NGT group.

Abstract
BACKGROUND In this paper, mulberry leaf powder (MLP) and konjac glucomannan (KGM) flour were used as raw materials, and animal experiments were designed to evaluate the effects of a mixture of MLP and KGM on bone density. The femoral bone microstructure of mice and pathological changes were observed by using micro-computed tomography) and haematoxylin and eosin (HE) staining methods, respectively. A three-point bending test was used to determine the biomechanical properties of the femur. RESULTS Results indicated that the calcium content of MLP was high, reaching 16 148.5 mg kg-1 , and the total proportion of water-soluble calcium, calcium pectinate, and calcium carbonate accounted for about 60% of the total calcium content. Serum alkaline phosphatase (AKP) activity was significantly lower, and serum calcium content was significantly higher (P < 0.05), in the MLP + KGM group (KM) than in the low-calcium control group, whereas no significant difference (P > 0.05) was found for serum phosphorus content. KM had a longer femur length, a higher bone mineral density (BMD) (P > 0.05), and significantly greater femur diameter, dry weight, index and bone calcium content (P < 0.05). However, these parameters were not significantly different from those of the calcium carbonate control group (P > 0.05). CONCLUSION The results indicate that the MLP/KGM mixture can reduce the high rate of bone turnover and the corresponding loss of bone mass caused by calcium deficiency and is thus effective in enhancing bone density. © 2019 Society of Chemical Industry.

Abstract
Skin tissue engineering aims to develop the effective healing strategy to repair the wound by optimizing skin scaffold materials. During the skin wound healing process, fibrin plays an important role due to the specific blood coagulation effect. In this study, the outstanding fibrin capability of konjac glucomannan (KGM) is demonstrated by the molecular dynamics simulation and confirmed by the protein adsorption experiments. A series of konjac glucomannan/polyvinyl alcohol (KGM/PVA) composites with different ratio are fabricated and their role in enhancing the skin repair is tested by in vitro cell culture and in vivo study. The Eads (adsorption energy) between fibrin and KGM is about 30% larger than that between fibrin and PVA. The fibrinogen adsorption rates of PVA and KGM/PVA (5:5) composites can reach about 20% and 60%, respectively. The results show the blood adsorption capacity of KGM/PVA (5:5) composite can reach about 13 g/g. After 7 days of cell culture, the optical density values of 3T3 fibroblasts on KGM/PVA (5:5) composite could reach 0.8. The mechanical properties of the composites are also verified to meet the practical needs. Thus, we propose a potential wound dressing material strategy based on the materials design and the intrinsic properties of KGM.

Abstract
Despite the excellent characteristics of carnauba wax (CW), hydrophobicity in particular, its complementary effect on the enhancement of konjac glucomannan (KGM) films remains poorly documented. KGM is a promising food bio-packaging material with excellent film-forming abilities, which could be improved further through modification of its hydrophilic nature using CW. In this study, emulsified composite films (KW) of KGM incorporated with varied CW concentration levels (0%, 4%, 8%, 12%, 16% and 20% w/w) were successfully prepared by solvent casting method. Increasing CW in KW films significantly improved the hydrophobicity, barrier and mechanical properties. The recorded improvements in functional properties relative to KGM films include fivefold solubility reduction, twofold contact angle and strength increment, as well as significant increase in stretch (61%) and decrease in water vapour transmission rate (48%). Microstructure analyses using scanning electron microscopy demonstrated remarkable improvements in cohesiveness, smoothness and homogeneity in KW aggregates with higher CW concentrations. Generally, our findings reveal the potential use of KW films as food packaging material which could reduce the availability of unsafe and environmentally unfriendly food packages in the market.

Abstract
In the recent era, bioactive compounds from plants have received great attention because of their vital health-related activities, such as antimicrobial activity, antioxidant activity, anticoagulant activity, anti-diabetic activity, UV protection, antiviral activity, hypoglycemia, etc. Previous studies have already shown that polysaccharides found in plants are not likely to be toxic. Based on these inspirational comments, most research focused on the isolation, identification, and bioactivities of polysaccharides. A large number of biologically active polysaccharides have been isolated with varying structural and biological activities. In this review, a comprehensive summary is provided of the recent developments in the physical and chemical properties as well as biological activities of polysaccharides from a number of important natural sources, such as wheat bran, orange peel, barely, fungi, algae, lichen, etc. This review also focused on biomedical applications of polysaccharides. The contents presented in this review will be useful as a reference for future research as well as for the extraction and application of these bioactive polysaccharides as a therapeutic agent.

Effect of Konjac Mannan Oligosaccharides on Glucose Homeostasis via the Improvement of Insulin and Leptin Resistance In Vitro and In Vivo. Nutrients 2019; 11:nu11081705. [PMID: 31344867 PMCID: PMC6723648 DOI: 10.3390/nu11081705] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2019] [Revised: 07/20/2019] [Accepted: 07/22/2019] [Indexed: 12/15/2022] Open
Abstract
Functional oligosaccharides, particularly konjac mannan oligosaccharides (KMOS), can regulate glucose metabolism. However, the molecular mechanisms involved in the hypoglycemic effect of KMOS remain largely unknown. Here, the effect of KMOS supplementation on glucose homeostasis was evaluated in both high-fat diet (HFD)-fed C57BL/6J mice and high-glucosamine-induced HepG2 cells. KMOS supplementation remarkably ameliorated the fasting blood glucose, glucose tolerance, and insulin tolerance of HFD-fed mice. Abnormalities of triglyceride and glycogen metabolism in the liver induced by the HFD were reversed by KMOS supplementation. The insulin signaling pathway was activated by KMOS, with stimulation of GLUT2 membrane translocation and glucose uptake in HepG2 cells via the AMPK pathway. Moreover, KMOS suppressed p-mTOR expression and stimulated the GSK-3β/CREB pathway via the AMPK pathway. KMOS significantly upregulated leptin receptor expression and downregulated PTP1B and SOCS3 levels in the liver and brain, with a decreased serum leptin concentration. Phosphorylation of JAK2 and STAT3 in the liver was activated by KMOS supplementation, while the expressions of Sirt1, Tfam, and Pgc1-α in the brain were elevated. Conclusively, KMOS attenuated HFD-induced glucose metabolism dysfunction through the regulation of insulin resistance and leptin resistance. This finding indicates that KMOS have potential value as an anti-hyperglycemic dietary supplement.

Abstract
Influences of different enzymatic hydrolysis degrees of konjac glucomannan (KGM) with various addition proportions on the structural characteristic of gluten protein and dough properties were evaluated. Results revealed that addition of KGM decreases the free sulfhydryl and freezable water content of dough, and KGM with different enzymatic hydrolysis degrees had more beneficial effects on strengthening the gluten structure by the raised molecular weight of gluten proteins and the increased disulfide bonds and β-sheet content, especially KGM with 15 min enzymatic hydrolysis treatment (KGM II). Besides, microstructure observation and thermal analysis results illustrated that addition of KGM promotes gluten cross-linking and improves the thermal stability of the gluten network structure. Dough possessed better elasticity, as well as tensile and texture properties with the addition of KGM than the control sample. And the KGM with 15 min enzymatic hydrolysis showed the most positive effect on dough quality than others, and 2.0% addition proportion is the most acceptable.
