This invention discloses a method for preparing resveratrol-loaded whey protein amyloid fibers based on moderate electric field modification. The method involves pretreating whey protein using a moderate electric field non-thermal effect, forming amyloid fibers through acid-thermal treatment, and further constructing a resveratrol delivery system based on protein fibrils. The resulting whey protein fiber-resveratrol complex exhibits excellent loading performance, antioxidant activity, and bioavailability, providing an effective carrier construction strategy for the efficient delivery and stabilization of hydrophobic and environmentally sensitive active molecules. This invention reveals the regulatory mechanism of the moderate-intensity electric field non-thermal effect in the protein fibrillation process, providing new technical ideas and theoretical references for the precise design of protein fiber structures and the development of functional protein-based delivery carriers, and providing technical support for the green preparation of protein fibrils and their in-depth development in functional foods.

The application relates to the technical field of drug delivery, in particular to a ZIF-8 / PDA composite material and a preparation method and application thereof. The ZIF-8 / PDA composite material provided by the application has good feasibility in terms of loading and delivering curcumin. The ZIF-8 material is modified by polydopamine, and the loading effect of the ZIF-8 material as a carrier on drugs is improved. The characterization results show that the drug loading performance of ZIF-8@PDA is obviously improved. The in-vitro release experiment results show that CuR@ZIF-8@PDA has more significant pH response drug release characteristics, shows good inhibition on Staphylococcus aureus and Escherichia coli, the hemolysis rate is 3.1%, is within a safe range, the inhibition on HepG2 cells is stronger than that of CuR@ZIF-8, and more obvious oxidative stress reaction and cell apoptosis can be induced.

The invention discloses a method for repairing damage of high-dose gallic acid to the performance of myofibrillar protein gel based on a beta-cyclodextrin metal organic framework. Extracting myofibrillar protein; the preparation method comprises the following steps: preparing a beta-cyclodextrin metal organic framework by taking beta-cyclodextrin and potassium ions as raw materials; mixing the gallic acid solution with the beta-cyclodextrin metal organic framework solution to obtain a gallic acid / beta-cyclodextrin metal organic framework inclusion compound solution; then adding myofibrillar protein for homogenization, then adding a Fenton oxidation system, uniformly mixing and reacting; and heating the reacted myofibrillar protein in a water bath, and cooling to obtain the performance-repaired myofibrillar protein gel based on the beta-cyclodextrin metal organic framework encapsulated gallic acid. The gallic acid is encapsulated by the beta-cyclodextrin metal organic framework, so that excessive aggregation of myofibrillar protein caused by high-dose gallic acid is reduced, more proteins are promoted to participate in formation of an ordered gel network structure, and the myofibrillar protein gel with higher gel strength and water binding capacity is obtained.
