Preparation method of nano EGCG protein rod

Abstract

The invention discloses a preparation method of a nano EGCG protein rod. The preparation method comprises the following steps of: S1, preparing nano EGCG: S11, obtaining casein sodium salt from milk,adding purified water and dissolving to obtain a 5% casein sodium salt solution; S12, adding tea polyphenol powder into the 5% casein sodium salt solution while stirring to obtain a mixed solution of0.5% tea polyphenol and 5% casein sodium salt; S13, carrying out ultrasonic treatment on the mixed solution of 0.5% tea polyphenol and 5% casein sodium salt for 5 minutes to obtain nano tea polyphenoldispersion liquid; S14, refrigerating and drying the nano tea polyphenol dispersion liquid to obtain the nano EGCG; and S2, preparing the nano EGCG protein rod. According to the preparation method disclosed by the invention, the used casein sodium salt, purified water, tea polyphenol powder, nano tea polyphenol, additives, milk mineral salt, nano EGCG, green tea powder, skimmed milk powder, protein raw materials, crushed nuts, resistant dextrin liquid, protein rod and the like are all non-toxic and do not damage human health.

Description

technical field [0001] The invention relates to the technical field of EGCG protein rods, in particular to a method for preparing nanometerized EGCG protein rods. Background technique [0002] Epigallocatechin gallate (EGCG) is the main component of catechin, mainly derived from green tea, and is the main component of tea polyphenols. The unique chemical structure of EGCG endows it with more biological activities, such as anti Oxidation, anti-cancer, anti-bacterial, anti-cardiovascular disease, anti-mutation and other biological activities, however, EGCG has poor stability and is easily affected by temperature, pH and oxygen concentration. Studies have found that nanotechnology is the best way to improve the stability of EGCG. A good way to transform dosage forms. [0003] Protein bars have the characteristics of comprehensive nutrition, good for human digestion and absorption, easy to carry, light and fashionable, and are favored by the majority of fitness people, and beco...

Problems solved by technology

[0004] The existing publication number is CN111420064A, and the name is: a protein-EGCG composite nanoparticle and anti-oxidation Pickering high internal phase emulsion. EGCG uses methanol or acetone as an organic solvent during the nano-treatment process, which is likely to cause methanol or acetone residues. Methanol and acetone Toxic substances, human contact will damage human health
