The bacteriostatic agent disclosed by the invention is particularly applicable to food and also applicable to medicines and daily articles.

Description

technical field [0001] The invention relates to the technical field of preparation of bacteriostatic agents, in particular to a preparation method of mango peel bacteriostatic agents. Background technique [0002] In addition to eating fresh mangoes, most of them are processed into dried mangoes, mango wine, mango vinegar, canned mangoes, etc. Processing fresh mangoes into various mango products can solve the problem of unstorable mangoes, but it also produces a large amount of mango peels. At present, the processing method of mango peel is generally discarded, which not only causes waste of raw materials but also pollutes the environment. Mango skin contains natural chemical components such as flavonoids and mangiferin, which have obvious inhibitory effects on many microorganisms. It is estimated that mango peels account for 7% to 24% of the weight of fresh fruits. If these mango peel wastes can be utilized, it will have an inestimable effect on increasing the added value...
