Abstract

The invention provides a preparation method of a banana composite coating antistaling agent. The method includes: adding carrageenan into deionized water to prepare a carrageenan solution; adding whey protein concentrate into deionized water to prepare a whey protein concentrate solution; mixing the carrageenan solution and the whey protein concentrate solution evenly, adding carboxymethylcellulose, calcium chloride, potassium citrate and sorbitol, and stirring the substances evenly; adding ascorbic acid, stirring the materials evenly, and performing degassing under a vacuum condition so as to obtain the composite coating antistaling agent. The composite coating antistaling agent prepared by the method provided by the invention has good antistaling effect, can inhibit crack of oxidase from banana epidermal cells, and can prolong the shelf life of bananas.

Description

technical field [0001] The invention relates to a preparation method of a banana composite coating preservative. Background technique [0002] Banana is a kind of fruit widely cultivated in tropical areas. Its fruit has ribs, yellow peel, white flesh, and sweet taste. Bananas are not only delicious but also have many medicinal properties. A large amount of carbohydrates and dietary fiber in bananas can prevent and resist cancer; it can also clear intestinal heat, laxative, ease gastric acid stimulation, and protect gastric mucosa; bananas contain angiotensin-converting enzyme inhibitory substances, which can Inhibit the rise of blood pressure, relax muscles, promote digestion, and help sleep. It is a fruit with high edible value. [0003] However, because the epidermal cells of the banana peel contain an oxidative enzyme, this enzyme is sealed in the cell. However, when bananas are stored at a lower temperature or stored for a long time, the cells will break down, and th...
