Skipjack myofibrillar protein metal nanometer composite membrane

Abstract

The invention discloses a skipjack myofibrillar protein metal nanometer composite membrane, which has the antioxidation and the antimicrobial activity and is prepared from skipjack ground meat. The composite membrane comprises the following ingredients in parts by weight: 20 to 22 parts of myofibrillar proteins, 0.16 to 0.24 part of ZnO, 0.6 to 1.1 parts of enteromorpha antioxidants and 4 to 5.5 parts of plasticizers. The skipjack myofibrillar protein metal nanometer composite membrane has the advantages that skipjack ground meat is used as major raw materials, and a new path is opened up for the high-valued utilization of skipjack processing leftovers; the prepared myofibrillar protein-ZnO nanometer composite membrane has the obvious characteristics of antioxidation, bacteriostasis and the like.

Description

technical field

[0001] The invention relates to an antibacterial composite film, in particular to a bonito myofibrillar protein metal nanocomposite film. Background technique

[0002] Myofibrillar protein accounts for more than 50% of fish protein, and is the most biologically functional structural protein group in fish. Its structure, gel and rheological properties have an important impact on the quality of fish products. In recent years, the research on myofibrillar protein has found that it has good film-forming properties, which has laid a theoretical foundation for its application in the field of biofilm preparation.

[0003] Tuna is an important pelagic commercial food fish with an annual catch of more than 6 million tons. During the processing of tuna and fish fillets, a large amount of leftovers such as minced meat are produced, which are not effectively utilized and precious fishery resources are wasted.

[0004] Based on this, the applicant prepared its myofibril...
