Use of minced tuna flesh nanoparticle composite membrane

Abstract

The invention discloses a use of a minced tuna flesh nanoparticle composite membrane. The minced tuna flesh is used for preparing a myofibrillar protein-chitosan nanoparticle composite membrane; the technical process comprises the steps of: preparing minced tuna flesh myofibrillar protein, preparing a tuna bone gelatin plasticizer and preparing chitosan nanoparticles; next, orderly adding the prepared myofibrillar protein, bone gelatin plasticizer and chitosan nanoparticles and an antioxidant to double distilled water in a certain ratio to form a film forming solution, and finally, pouring the successfully prepared film forming solution onto a polyvinyl chloride crystal plate, scraping, drying and uncovering a film, thereby obtaining the myofibrillar protein-chitosan nanoparticle composite membrane. The prepared myofibrillar protein-chitosan nanoparticle composite membrane has remarkable characteristics of oxidation resistance, bacteriostasis and the like, and can be applied to bacteriostasis or oxidation resistance in the packaging field.

Description

Technical field [0001] The present invention is the field of food quality and safety technology, especially the use of a tuna shattered nano -sano -ball composite film. Background technique [0002] The large amount of non -degradable plastic packaging materials have caused an increasingly negative impact on the environment.Therefore, searching for non -degradable plastic packaging materials has become a hot spot in the field of food packaging.Protein resources are abundant, biomagitariated, and strong plasticized. More importantly, it is better than polysaccharides such as oxygen and carbon dioxide resistance in food packaging.Therefore, the use of protein resources to prepare edible membranes has attracted widespread attention. [0003] Tuna is an important consumer fish for ocean -sex goods, with an annual capture of more than 6 million tons.During the processing of tuna, a large number of minced meat and fish bones failed to be effectively used, which wasted valuable fishery ...

AI Technical Summary

Problems solved by technology

In the process of tuna processing, a large amount of minced meat and fish bones have not been effectively utilized, wasting valuable fishery resources and limiting the in-depth development of the industry

After searching, there is no report on the preparation of biofilms for packaging using myofibrillar protein prepared from minced tuna and nano-microspheres prepared from chitosan
