Abstract

The invention discloses a preparation method of biomacromolecule compound stable quercetagetin, and belongs to the technical field of transmission systems in function factor steady-state technology. According to the method, zein and propylene glycol alginate serve as raw materials, the quercetagetin serves as bioactive substances, a zein-propylene glycol alginate biomacromolecule compound loaded the quercetagetin is prepared by an anti-solvent co-precipitation method, the weight ratio of the zein to the propylene glycol alginate is 40:1-1:10, and the adding amount of the quercetagetin is 0.1wt%-2.0wt%. The dried biomacromolecule compound is spongy, water solubility of the quercetagetin is remarkably improved, the embedding rate of the quercetagetin is 90% or more, the loading amount of the quercetagetin is 6%-15%, the light degradation rate and the heat degradation rate of the quercetagetin are reduced, and the bioavailability of the quercetagetin is obviously improved. The preparation method can provide new ideas and new pathways for function factor stabilization.

Description

technical field [0001] The invention belongs to the technical field of delivery system in the stabilization technology of functional factors, and in particular relates to a preparation method of stable quercetin tagetin of biomacromolecular complex. Background technique [0002] As a kind of polyhydroxy flavonoids, quercetin tagetin has various biological functions and pharmacological effects such as anti-oxidation, anti-cancer, anti-inflammation, anti-bacterial, anti-virus, etc. It can effectively prevent cardiovascular diseases and significantly improve human immunity . However, quercetin is insoluble in water, sensitive to light, heat, and oxygen, prone to degradation, and low in bioavailability, which obviously limits its application in the food field. Existing studies have shown that polysaccharides and protein biomacromolecules can be used for the embedding, protection and delivery of various bioactive substances due to their safety, biodegradability and strong stabil...
