[PMID: 39053392 DOI: 10.1016/j.foodchem.2024.140526] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 07/16/2024] [Accepted: 07/17/2024] [Indexed: 07/27/2024]
Abstract
Thermal processing can alter the biological activity of seed phytochemicals in various ways, thus improving shelf life, bioavailability, oxidative stability, and oil yield; it can also decrease the content of antinutritional compounds, reduce cytotoxic activity and increase the total phenolic content of the seeds. However, this treatment can also inactivate beneficial compounds, including phenolics. This review describes the effect of different thermal processing methods on the content, activity, and bioavailability of chemical compounds from different edible seeds. The outcome is dependent on the method, temperature, time of processing, and type of seeds. Although thermal processing has many benefits, its precise effect on different species requires further clarification to determine how it influences their phytochemical content and biological activity, and identify the optimal conditions for processing.

Abstract
Theaflavins are beneficial to human health due to various bioactivities. Biosynthesis of theaflavins using polyphenol oxidase (PPO) is advantageous due to cost effectiveness and environmental friendliness. In this review, studies on the mechanism of theaflavins formation, the procedures to screen and prepare PPOs, optimization of reaction systems and immobilization of PPOs were described. The challenges associated with the mass biosynthesis of theaflavins, such as poor enzyme activity, undesirable subproducts and inclusion bodies of recombinant PPOs were presented. Further strategies to solve these challenges and improve theaflavins production, including enzyme engineering, immobilization enzyme technology, water-immiscible solvent-water biphasic systems and recombinant enzyme technology, were proposed.

Abstract
Phytase enzyme found in plants, animals, and microorganisms is mainly involved in catalyzing the systematic removal of a phosphate group from phytic acid. Enzyme immobilization is one of the cost-effective methods for the wide usage of enzymes in the industrial sector. This paper reports the covalent immobilization of phytase on glutaraldehyde-activated aluminum oxide beads. The immobilization yield, efficiency, and activation energy were found to be 47.8%, 71.5%, and 15.78 J/mol, respectively. The bound enzyme displayed a shift in pH optima from 5.5 to 4.5, which is more beneficial to increase digestibility in comparison with the free enzyme. Immobilized phytase retained 42.60% of its activity after 1.0 h incubation at 80 °C, whereas free enzyme retained only 4.20% of its activity. Thermodynami increase in half-lives, D-values, enthalpy and free energy change after covalent immobilization could be credited to the enhanced stability. Immobilized phytase could be reused for five consecutive cycles retaining 51% of its initial activity with sodium phytate. The immobilized phytase was also found effective to hydrolyze the soybean meal, thus increasing the digestibility of poultry feed. The hydrolyzing reaction of soybean meal was carried out for six consecutive cycles and immobilized phytase retained nearly 50% of activity till the fifth cycle. The amount of phosphorus released after treatment with immobilized phytase was far higher than that from free phytase. Immobilization on this support is significant, as this support can sustain high mechanical resistance at high pH and temperature. This considerable stability and reusability of the bound enzyme may be advantageous for its industrial application.

Abstract
Phytases are important enzymes used for eliminating the anti-nutritional properties of phytic acid in food and feed ingredients. Phytic acid is major form of organic phosphorus stored during seed setting. Monogastric animals cannot utilize this phytate-phosphorus due to lack of necessary enzymes. Therefore, phytic acid excretion is responsible for mineral deficiency and phosphorus pollution. Phytases have been reported from diverse microorganisms, however, fungal phytases are preferred due to their unique properties. Aspergillus species are the predominant producers of phytases and have been explored widely as compared to other fungi. Solid-state fermentation has been studied as an economical process for the production of phytases to utilize various agro-industrial residues. Mixed substrate fermentation has also been reported for the production of phytases. Physical and chemical parameters including pH, temperature, and concentrations of media components have significantly affected the production of phytases in solid state fermentation. Fungi produced high levels of phytases in solid state fermentation utilizing economical substrates. Optimization of culture conditions using different approaches has significantly improved the production of phytases. Fungal phytases are histidine acid phosphatases exhibiting broad substrate specificity, are relatively thermostable and protease-resistant. These phytases have been found effective in dephytinization of food and feed samples with concomitant liberation of minerals, sugars and soluble proteins. Additionally, they have improved the growth of plants by increasing the availability of phosphorus and other minerals. Furthermore, phytases from fungi have played an important roles in bread making, semi-synthesis of peroxidase, biofuel production, production of myo-inositol phosphates and management of environmental pollution. This review article describes the production of fungal phytases in solid state fermentation and their biotechnological applications.

Abstract
BACKGROUND Novel feeds for improved feed intake and for enhanced nutrient bioavailability have recently attracted attention. Insoluble dietary fibers, especially rice and wheat bran, have generated much interest due to their nutritional value. Incorporating insoluble dietary fiber into diets could be a viable way to maximize the feed conversion ratio. RESULTS Cross-linked phytase aggregates (CLPA) were synthesized by precipitating enzymes followed by cross-linking with 5 mmol L-1 glutaraldehyde, yielding 88.24 (U g-1 ) of enzyme load without the assistance of a proteic feeder. The epitome of the study is the dephosphorylation of wheat bran and rice bran by varying pH, enzyme concentration, and temperature. The highest inorganic phosphorus liberation by 150 U L--1 of free phytase was 23.72 (wheat bran) and 48.08 mg g-1 (rice bran) after 12 h of incubation. Furthermore, 150 U L-1 of CLPA liberated 28.72 (wheat bran) and 52.08 mg g-1 (rice bran) of inorganic phosphorus with an incubation time of 12 h. CONCLUSION Thermostable free phytase was insolubilized to dephosphorylate the agro-residue, namely, wheat bran and rice bran, to reduce the anti-nutritional factor (the phytate content) of these insoluble dietary fibers. © 2022 Society of Chemical Industry.

Abstract
Immobilized enzyme-based catalytic constructs could greatly improve various industrial processes due to their extraordinary catalytic activity and reaction specificity. In recent decades, nano-enzymes, defined as enzyme immobilized on nanomaterials, gained popularity for the enzymes' improved stability, reusability, and ease of separation from the biocatalytic process. Thus, enzymes can be strategically incorporated into nanostructured materials to engineer nano-enzymes, such as nanoporous particles, nanofibers, nanoflowers, nanogels, nanomembranes, metal-organic frameworks, multi-walled or single-walled carbon nanotubes, and nanoparticles with tuned shape and size. Surface-area-to-volume ratio, pore-volume, chemical compositions, electrical charge or conductivity of nanomaterials, protein charge, hydrophobicity, and amino acid composition on protein surface play fundamental roles in the nano-enzyme preparation and catalytic properties. With proper understanding, the optimization of the above-mentioned factors will lead to favorable micro-environments for biocatalysts of industrial relevance. Thus, the application of nano-enzymes promise to further strengthen the advances in catalysis, biotransformation, biosensing, and biomarker discovery. Herein, this review article spotlights recent progress in nano-enzyme development and their possible implementation in different areas, including biomedicine, biosensors, bioremediation of industrial pollutants, biofuel production, textile, leather, detergent, food industries and antifouling.

Abstract
Phytases are the most widely used food and feed enzymes, which aid in nutritional improvement by reducing anti-nutritional factor. Despite the benefits, enzymes usage in the industry is restricted by several factors such as their short life-span and poor reusability, which result in high costs for large-scale utilization at commercial scale. Furthermore, under pelleting conditions such as high temperatures, pH, and other factors, the enzyme becomes inactive due to lesser stability. Immobilization of phytases has been suggested as a way to overcome these limitations with improved performance. Matrices used to immobilize phytases include inorganic (Hydroxypatite, zeolite, and silica), organic (Polyacrylamide, epoxy resins, alginate, chitosan, and starch agar), soluble matrix (Polyvinyl alcohol), and nanomaterials including nanoparticles, nanofibers, nanotubes. Several surface analysis methods, including thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC), and FTIR analysis, have been used to characterize immobilized phytase. Immobilized phytases have been used in a broad range of biotechnological applications such as animal feed, biodegradation of food phytates, preparations of myo-inositol phosphates, and sulfoxidation by vanadate-substituted peroxidase. This article provides information on different matrices used for phytase immobilization from the last two decades, including the process of immobilization and support material, surface analysis techniques, and multifarious biotechnological applications of the immobilized phytases.
