Assembly of foxtail millet prolamin/chitosan hydrochloride/carboxymethyl-beta-cyclodextrin in acetic acid aqueous solution for enhanced curcumin retention

The aim of this work is to investigate the assembly of foxtail millet prolamin (FP) with chitosan hydrochloride (CHC) and carboxymethyl-beta-cyclodextrin (CMCD) in acetic acid aqueous solutions. The proportion of acetic acid has a positive impact on the disintegration of FP. With the use of 91.0 % (v/v) acetic acid, FP forms smaller particles of approximately 45 nm (naked FP particles) and 220 nm (FP - CHC - CMCD hybrid particles). In the case of using 61.5 % (v/v) acetic acid, the microstructures of bare FP particles and 570 nm composite FP nanoparticles (NPs) are looser, about 485 nm. Acetic acid inhibits the noncovalent bonds, including the hydrophobic interactions, hydrogen bonding and electrostatic attractions between FP and polysaccharides. Therefore, 3.8 % (v/v) acetic acid can nucleate FP to form more compact FP hybrid particles for delivering curcumin (Cur) with higher encapsulation efficiency, storage stability and release performance, and improve the antibacterial and anticancer activity of Cur.

Fabrication and Characterization of Gelatin-Finger Citron Polysaccharide Nanoparticles for Enhanced Solubility and Bioavailability of Luteolin in Treating Acute Alcoholic Liver Disease

Luteolin (Lut) is a natural flavonoid that has been widely used in the treatment of liver and glycolipid metabolic diseases. However, poor water solubility and bioavailability limit its efficacy and application. To overcome these challenges, a protein-polysaccharide composite nanoparticle (L-GF NPs) for Lut delivery was prepared by a self-assembly method based on amphiphilic gelatin and active finger citron polysaccharide (FCP). The L-GF NPs were approximately spherical in shape and were formed by hydrogen bonding, electrostatic interaction, and hydrophobic interaction. Lut was encapsulated in the nanoparticles in an amorphous state, and the encapsulating efficiency was 79.49%. The efficacy of L-GF NPs was evaluated by intragastric administration of an alcoholic liver disease (ALD) mouse model. L-GF NPs have been demonstrated to significantly ameliorate the symptoms of ALD mice, which are mainly achieved by reducing lipid accumulation and oxidative stress and inhibiting the NF-κB pathway. In conclusion, the aqueous solubility and bioavailability of Lut were markedly enhanced by FCP encapsulation. Meanwhile, the combined effect of Lut and FCP significantly ameliorated ALD and attenuated alcohol-induced lipid metabolic disorders and oxidative damage. This provides a new strategy to promote the prevention and treatment of ALD.

Synergistic growth suppression of Fusarium oxysporum MLY127 through Dimethachlon Nanoencapsulation and co-application with Bacillus velezensis MLY71

Fusarium oxysporum is a destructive plant pathogen with robust survival mechanisms, complicating control efforts. This study aimed to develop nanoformulated fungicides, screen antagonistic bacteria, and evaluate their combined efficacy. A novel self-emulsifying nanoemulsion (DZW) was formulated using zein and benzaldehyde-modified wheat gluten (BgWG) as carriers for dimethachlon (DTN). The preparation process optimized material ratios and emulsification techniques. Concurrently, antagonistic bacterial strains against F. oxysporum were screened via the plate standoff method, identifying Bacillus velezensis MLY71 as both antagonistic and compatible with DTN. The DZW nanoemulsion achieved a particle size of 93.22 nm, an encapsulation efficiency (EE) of 90.57%, and a DTN loading capacity (LC) of 67.09%, with sustained release over 96 h. The combination of DTN (0.04 mg·mL⁻¹) and B. velezensis MLY71 (1 × 10⁴ CFU·mL⁻¹) achieved a 76.66% inhibition rate against F. oxysporum MLY127, 1.71 times greater than DTN alone, indicating significant synergy. At a DTN concentration of 0.20 mg·mL⁻¹, the combination of DZW and MLY71 showed a synergy coefficient of 1.33. This synergy was also observed in soil environments, indicating its adaptability for controlling soil-borne pathogens. As sustainable management continues to gain attention in agricultural disease control, this study offers a promising strategy for achieving higher efficacy with the same fungicide dose or satisfactory control with reduced fungicide application. The excellent drug-loading performance of BgWG also expanded the applications of the wheat by-product gluten.

Zein/fucoidan-coated phytol nanoliposome: preparation, characterization, physicochemical stability, in vitro release, and antioxidant activity

BACKGROUND

To improve phytol bioavailability, a novel method of magnetic stirring and high-pressure homogenization (HPH) combination was used to prepare zein/fucoidan-coated phytol nanoliposomes (P-NL-ZF). The characterization, the simulated in vitro digestion, and the antioxidant activity of these phytol nanoliposomes from the different processes have been studied.

RESULTS

Based on the results of dynamic light scattering (DLS) and gas chromatography-mass spectrometer (GC-MS) analysis, P-NL-ZF prepared through the combination of magnetic stirring and HPH exhibited superior encapsulation efficiency at 76.19% and demonstrated exceptional physicochemical stability under a series of conditions, including storage, pH, and ionic in comparison to single method. It was further confirmed that P-NL-ZF by magnetic stirring and HPH displayed a uniform distribution and regular shape through transmission electron microscopy (TEM). Fourier-transform infrared (FTIR) spectroscopy and differential scanning calorimetry (DSC) analysis showed that electrostatic interactions and hydrogen bonding were the primary driving forces for the formation of composite nanoliposomes. Additionally, an in vitro digestion study revealed that multilayer composite nanoliposomes displayed significant and favorable slow-release properties (58.21%) under gastrointestinal conditions compared with traditional nanoliposomes (82.36%) and free phytol (89.73%). The assessments of chemical and cell-based antioxidant activities demonstrated that the coating of zein/fucoidan on phytol nanoliposomes resulted in enhanced effectiveness in scavenging activity of ABTS free radical and hydroxyl radical and mitigating oxidative damage to HepG2 cells.

CONCLUSION

Based on our studies, the promising delivery carrier of zein/fucoidan-coated nanoliposomes is contributed to the encapsulation of hydrophobic natural products and enhancement of their biological activity. © 2024 Society of Chemical Industry.

Epigallocatechin-3-gallate stabilizes aqueous curcumin by generating nanoparticles and its application in beverages

In this study, we addressed the limited water solubility of curcumin by utilizing epigallocatechin-3-gallate to form nanoparticles through self-assembly. The resulting particles, ranging from 100 to 150 nm, exhibited a redshift in the UV-visible spectrum, from 425 nm to 435 nm, indicative of potential π-π stacking. Molecular docking experiments supported this finding. Curcumin loaded with epigallocatechin-3-gallate showed exceptional dispersibility in aqueous solutions, with 90.92 % remaining after 60 days. The electrostatic screening effect arises from the charge carried by epigallocatechin-3-gallate on the nanoparticles, leading to enhanced retention of curcumin under different pH, temperature, and ionic strength conditions. Furthermore, epigallocatechin-3-gallate can interact with other hydrophobic polyphenols, improving their dispersibility and stability in aqueous systems. Applying this principle, a palatable beverage was formulated by combining turmeric extract and green tea. The nanoparticles encapsulated with epigallocatechin-3-gallate show potential for improving the applicability of curcumin in aqueous food systems.

Oregano essential oil encapsulated in zein-pectin-chitosan nanoparticles to improve the storage quality of Harbin red sausage

In this study, the effect of oregano essential oil loaded in zein-pectin-chitosan (Zein-PC-CS-OEO) nanoparticles on the quality of Harbin red sausage during storage was examined. Zein-PC-CS-OEO nanoparticles exhibit the better encapsulation efficiency, antioxidant and antibacterial properties than these of other prepared nanoparticles, which were subsequently incorporated into Harbin red sausage with different concentrations. The physicochemical properties, bacterial community structure, and flavor characteristics of the Harbin red sausage were determined. Both thiobarbituric acid values and the growth of dominant spoilage bacteria in Harbin red sausage are inhibited by Zein-PC-CS-OEO nanoparticles, while the total aerobic bacteria count is reduced. These results indicate that the storage quality of Harbin red sausage is improved by Zein-PC-CS-OEO nanoparticles. It is worth noting that the shelf life of Harbin red sausage supplemented with 0.1 % Zein-PC-CS-OEO nanoparticles is extended to 9 d, and the flavor characteristics of which are better maintained. This study provides a new approach to extend the application of essential oil and improve the storage quality of Harbin red sausage.

Fabrication of zein-tamarind seed polysaccharide-curcumin nanocomplexes: their characterization and impact on alleviating colitis and gut microbiota dysbiosis in mice

In this work, a zein-tamarind seed polysaccharide (TSP) co-delivery system was fabricated using an anti-solvent precipitation method. The formation mechanism, characterization, and effect on alleviating colitis and gut microbiota dysbiosis in mice of zein-TSP-curcumin (Z/T-Cur) nanocomplexes were investigated. Hydrogen bonding and the hydrophobic effect played a key role in the formation of Z/T-Cur nanocomplexes, and the interactions were spontaneous and driven by enthalpy. The encapsulation efficiency, loading capacity, and bioavailability increased from 60.8% (Zein-Cur) to 91.7% (Z/T-Cur1:1), from 6.1% (Zein-Cur) to 18.3% (Z/T-Cur1:1), and from 4.7% (Zein-Cur) to 20.0% (Z/T-Cur1:1), respectively. The Z/T-Cur significantly alleviated colitis symptoms in DSS-treated mice. Additionally, the prepared nanocomplexes rebalanced the gut microbiota composition of colitis mice by increasing the abundance of Akkermansia. Odoribacter and Monoglobus were rich in the Z-T-Cur treatment group, and Turicibacter and Bifidobacterium were rich in the zein-TSP treatment group. This study demonstrated that the TSP could be helpful in the targeted drug delivery system.

L-carnitine modified nanoparticles target the OCTN2 transporter to improve the oral absorption of jujuboside B

As a bioactive saponin derived from the seeds of Ziziphus jujuba Mill. var. spinosa (Bunge) Hu ex H. F. Chow, jujuboside B (JuB) shows great potential in anti-anxiety, anti-depression and improving learning and memory function. However, its oral bioavailability is very poor. In this study, a novel drug-loading nanoparticles system was prepared with polyethylene glycol and polylactic-co-glycolic acid copolymer (PEG-PLGA), and further modified with L-carnitine (LC) to target intestinal organic cation/carnitine transporter 2 (OCTN2) to improve the oral absorption of JuB. Under the optimized preparation conditions, the particle sizes of obtained JuB-PEG-PLGA nanoparticles (B-NPs) and LC modified B-NPs (LC-B-NPs) were 110.67 ± 11.37 nm and 134.00 ± 2.00 nm with the entrapment efficiency (EE%) 73.46 ± 1.26 % and 76.01 ± 2.10 %, respectively. The pharmacokinetics in SD rats showed that B-NPs and LC-B-NPs increased the bioavailability of JuB to 134.33 % and 159.04 % respectively. In Caco-2 cell model, the prepared nanoparticles significantly increased cell uptake of JuB, which verified the pharmacokinetic results. The absorption of LC-B-NPs mainly depended on OCTN2 transporter, and Na+ played an important role. Caveolin and clathrin were involved in the endocytosis of the two nanoparticles. In conclusion, both B-NPs and LC-B-NPs can improve the oral absorption of JuB, and the modification of LC can effectively target the OCTN2 transporter.

A curcumin oral delivery system based on sodium caseinate and carboxymethylpachymaran nanocomposites

The food industry has paid lots of attentions to curcumin because of its potential bioactive qualities. However, its use is severely constrained by its low bioavailability, stability and water solubility. Herein, we created sodium caseinate and carboxymethylpachymaran (CMP) nanoparticles (SMCNPs) that were loaded with curcumin. The composite nanoparticles were spherical, as characterized by SEM and TEM, the fluorescence spectroscopy, FTIR and XRD research revealed that hydrogen bonding, hydrophobic interaction and electrostatic interaction were the main drivers behind the creation of the nanoparticles. The SMCNPs exhibited lower particle size, greater dispersion and higher encapsulation rate when the mass ratio of sodium caseinate to CMP was 3:5 (particle size of 166.8 nm, PDI of 0.15, and encapsulation efficiency of 88.07 %). The composite nanoparticles had good antioxidant activity, physical stability and sustained release effect on intestinal tract during the in vitro simulation experiments, successfully preventing the early release of curcumin into gastric fluid. Finally, cytotoxicity studies told that the prepared composite nanoparticles have good biocompatibility and can inhibit the growth of tumor cells (HT-29). In conclusion, using CMP and sodium caseinate as carriers in this study may open up a fresh, environmentally friendly, and long-lasting way to construct a bioactive material delivery system.

Optimization of food-grade colloidal delivery systems for thermal processing applications: a review

Colloidal delivery systems are widely used in the food industry to enhance the dispersibility, stability, efficacy, or bioavailability. However, when exposed to the high temperature, delivery systems are often prone to degradation, which limits its application in thermal processing. In this paper, the effects of thermal processing on the performance of traditional protein-based or starch-based delivery systems are firstly described, including the molecular structure changes of proteins, starches or lipids, and the degradation of embedded substances. These effects are unfavorable to the application of the delivery system in thermal processing. Then, strategies of improving the heat resistance of food grade colloid delivery system and their use in frying, baking and cooking food are mainly introduced. The heat resistance of the delivery system can be improved by a variety of strategies, including the development of new heat-resistant materials, the addition of heat-resistant coatings to the surface of delivery systems, the cross-linking of proteins or starches using cross-linking agents, the design of particle structures, the use of physical means such as ultrasound, or the optimization of the ingredient formula. These strategies will help to expand the application of heat-resistant delivery systems so that they can be used in real thermal processing.

Purification and characterization of a chicory polysaccharide and its application in stabilizing genistein for cancer therapy

Genistein is an isoflavone with chemopreventive and therapeutic effects on various types of cancers. Apparently, in contrast to the advantages of multi-target therapy, the poor water solubility of this molecule is a major obstacle to its clinical application. In this work, zein/chicory polysaccharide nanoparticles (G-zein-P NPs) were prepared by pH-induced antisolvent precipitation method for the encapsulation of genistein. Firstly, an acidic polysaccharide (CIP70-2) with a molecular weight of 66.7 kDa was identified from the roots of chicory (Cichorium intybus). This natural macromolecule was identified as a plant pectin, for which the structure included RG-I (rhamnogalacturonan I) and HG (homogalacturonan) regions. Using this polysaccharide, G-zein-P NPs were prepared, in which the water solubility of genistein was improved by encapsulation. The encapsulation efficiency and loading efficiency of genistein by composite nanoparticles reached 99.0 % and 6.96 %, respectively. In vitro tumor inhibition experiments showed that the inhibitory effect of G-zein-P NPs on HepG2 cells was twice that of unencapsulated genistein. Moreover, the significant inhibition of tumor development and metastasis by G-zein-P NPs was observed in zebrafish xenograft models. The results suggested that zein/chicory polysaccharide nanoparticles may be a promising delivery carrier for genistein application in cancer prevention and therapy.

Co-encapsulation of curcumin and quercetin with zein/HP-β-CD conjugates to enhance environmental resistance and antioxidant activity

In this study, composite nanoparticles consisting of zein and hydroxypropyl beta-cyclodextrin were prepared using a combined antisolvent co-precipitation/electrostatic interaction method. The effects of calcium ion concentration on the stability of the composite nanoparticles containing both curcumin and quercetin were investigated. Moreover, the stability and bioactivity of the quercetin and curcumin were characterized before and after encapsulation. Fluorescence spectroscopy, Fourier Transform infrared spectroscopy, and X-ray diffraction analyses indicated that electrostatic interactions, hydrogen bonding, and hydrophobic interactions were the main driving forces for the formation of the composite nanoparticles. The addition of calcium ions promoted crosslinking of the proteins and affected the stability of the protein-cyclodextrin composite particles through electrostatic screening and binding effects. The addition of calcium ions to the composite particles improved the encapsulation efficiency, antioxidant activity, and stability of the curcumin and quercetin. However, there was an optimum calcium ion concentration (2.0 mM) that provided the best encapsulation and protective effects on the nutraceuticals. The calcium crosslinked composite particles were shown to maintain good stability under different pH and simulated gastrointestinal digestion conditions. These results suggest that zein-cyclodextrin composite nanoparticles may be useful plant-based colloidal delivery systems for hydrophobic bio-active agents.

Nanoparticles prepared by polysaccharides extracted from Biyang floral mushroom loaded with resveratrol: Characterization, bioactivity and release behavior under in vitro digestion

Resveratrol (RES) is a common active factor in the functional food field, but poor water solubility and low bioavailability have limited its application. In the present study, the novel nanoparticles (RES-CBFMP NPs) using floral mushroom polysaccharide as the wall material have been developed for delivering RES, aiming to overcome its application shortcomings. After ratio optimization, RES-CBFMP NPs (RES-CBFMP,1:8 w/w), which combined through the hydrogen bonds between RES and CBFMP, showed the best overall performance, with the encapsulation efficiency (EE) of 49.74 ± 0.16%, loading efficiency (LE) of 5.53 ± 0.02%, particle size of 158.56 ± 1.97 nm and zeta-potential of -17.56 ± 0.24 mV. In addition, RES-CBFMP NPs exhibited good physicochemical stabilities, sustained gastrointestinal digestive release property, as well as improved in vitro antioxidant and anticancer activities. This study may contribute to the development of RES oral delivery systems and the application of hydrophobic active molecules in the functional food field.

Development of fish gelatin/carrageenan/zein bio-nanocomposite active-films incorporated with turmeric essential oil and their application in chicken meat preservation

Gelatin/carrageenan (Ge/Car) active packaging films incorporated with turmeric essential oil (TEO) encapsulated in zein nanoparticles (ZNP) were developed. The efficacy of these active packaging films and their antimicrobial properties were also investigated to ensure their practical application. Three different types of nanocomposite films (Ge/Car, Ge/Car/TEO, and Ge/Car/ZNP) were prepared. The characterization of the films was elucidated using Fourier transform infrared (FTIR), X-ray diffraction analyses (XRD), and scanning electron microscope (SEM). Physicochemical and mechanical properties of the films were enhanced, owing to the application of TEO-containing nanocomposites. Supercritical-CO₂ extracted TEO showed excellent biological activities, alongside GC-MS analysis identified that TEO contained 33 bioactive compounds where the major constituent was Zingiberene. ZNP proved an excellent carrier of TEO. The nanocomposite film sustainably released TEO, improving the shelf life of the chicken meat by reducing bacterial colonies from 3.08 log CFU/g to 2.81 log CFU/g after 14 days incubation against Salmonella enterica compared with 6.66 log CFU/g observed in the control film. The overall results of this study suggest that the nanocomposite active film is an excellent candidate for food packaging to ensure a better world.

Properties of curcumin-loaded zein-tea saponin nanoparticles prepared by antisolvent co-precipitation and precipitation

The properties of nutraceutical-loaded biopolymer nanoparticles fabricated by antisolvent co-precipitation (ASCP) and precipitation (ASP) were compared. Curcumin-loaded zein-tea saponin nanoparticles were fabricated using both methods and then their structural and physicochemical properties were characterized. The diameter of the nanoparticles prepared by ASCP were smaller (120-130 nm) than those prepared by ASP (140-160 nm). The encapsulation efficiency of the ASCP-nanoparticles (80.0%) was higher than the ASP-ones (71.0%) at a zein-to-curcumin mass ratio of 3:1, which was also higher than previous studies. The storage and light stability of curcumin was higher in zein-saponin nanoparticles than in zein nanoparticles. All nanoparticles had good water dispersibility after freeze-drying and rehydration. This study shows that nanoparticles produced by antisolvent co-precipitation have superior properties to those produced by antisolvent precipitation. The co-precipitation method leads to a higher encapsulation efficiency, smaller particle size, and greater storage stability, which may be advantageous for some applications.

It also highlights the potential advantages of using polysaccharides for the construction of nano-delivery systems, such as nanoparticles, nanogels, nanoemulsions, nanocapsules, and nanofibers. Moreover, the application of delivery systems assembled from polysaccharides is summarized, with a focus on pH-responsive delivery of bioactives. There are some key findings and conclusions: Nanoscale polysaccharide delivery systems provide several advantages, including improved water-dispersibility, flavor masking, stability enhancement, reduced volatility, and controlled release; Polysaccharide nanocarriers can be used to construct pH-responsive delivery vehicles to achieve intestinal-targeted delivery and controlled release of bioactive ingredients; Polysaccharides can be used in combination with other biopolymers to form composite delivery systems with enhanced functional attributes.

Curcumin-loaded HKUST-1@ carboxymethyl starch-based composites with moisture-responsive release properties and synergistic antibacterial effect for perishable fruits

The spoilage of fruit is one of the most important causes of fruit waste. High humidity by fresh fruit respiration leads to bacterial reproduction, which is the key factor of products corruption. Herein, a biological multifunctional film (Cur-HKUST-1@CMS/PVA) for fruits preservation with a high moisture environment was developed by cross-linking carboxymethyl starch (CMS)/polyvinyl alcohol (PVA) with MOF-199 (HKUST-1), and loaded with curcumin. The hydrophilic CMS facilitates water adsorption and moisture can stimulate curcumin release from HKUST-1. HKUST-1 not only acts as curcumin carriers but also forms synergistic antibacterial with curcumin to improve the antibacterial activity of the composites. XRD and SEM demonstrated that moisture disrupts the structure of HKUST-1 and releases curcumin and the results showed that the release of curcumin increased from 25.11 % to 58.32 % after moisture stimulation. In addition, Cur-HKUST-1@CMS/PVA had excellent antibacterial activity and antioxidant ability. As validation, the film can keep pitaya and avocado freshness at least 4 days longer than the control, confirming the effectiveness of Cur-HKUST-1@CMS/PVA in preventing fruit decay. Consequently, Cur-HKUST-1@CMS/PVA is a promising active packaging material for improve the shelf life of perishable fruits.

Zein is a natural, biocompatible, and biodegradable polymer widely used in the pharmaceutical, biomedical, and packaging fields because of its low water vapor permeability, antibacterial activity, and hydrophobicity. It is a vegetal protein extracted from renewable resources (it is the major storage protein from corn). There has been growing attention to producing zein-based drug delivery systems in the recent years. Being a hydrophobic biopolymer, it is used in the controlled and targeted delivery of active principles. This review examines the present-day landscape of zein-based microparticles and nanoparticles, focusing on the different techniques used to obtain particles, the optimization of process parameters, advantages, disadvantages, and final applications.

Glycosylation of Zein Hydrolysate as a Nanocarrier for Lutein Delivery: Preparation and Stability

Lutein is a functional carotenoid that has a wide range of physiological benefits in humans. However, it easily degrades and becomes inactivated during storage and processing, resulting in low bioavailability. The development of new nanocarriers can effectively improve the stability and biological activity of lutein. In this study, zein hydrolysate (ZH) carriers were glycosylated with glucosamine (GLU) under the action of transglutaminase, and lutein-loaded glycosylated ZH nanoparticles (GZH-LUT) were constructed by liquid–liquid dispersion. The results showed that the GZH-LUT particles had a narrow size distribution in the range of 200–300 nm and a decreased zeta potential and polydispersity index. In particular, GZH trapped lutein more efficiently than ZH. In addition, GZH-LUT had better physical and chemical properties, including better water solubility, oxidative stability, and environmental stability than free lutein and ZH-LUT. These results indicate that glycosylated zein hydrolysate has the potential to be used as a novel protein-based nanocarrier to enhance the solubility and stability of lutein, which can further improve its bioavailability.
