Abstract

The invention provides a preservative for navel oranges and a preparation method thereof. The preservative is mainly prepared from the following components by weight: 5 to 10 parts of chitosan, 15 to25 parts of chitosan oligosaccharide, 10 to 30 parts of glacial acetic acid, 1 to 5 parts of glycerin and 0.1 to 0.5 part of NaCl, with the balance being water, wherein the weight parts of the above components sum to 100 parts. The preservative provided by the invention can substantially prolong the preservation time of navel oranges and greatly reduce the rate of rotten fruit, and has the advantages of simple formula, convenient operation, etc.

Description

technical field [0001] The invention relates to the technical field of antistaling agents, in particular to a navel orange antistaling agent. technical background [0002] Navel orange has the advantages of tender pulp, strong sweet flavor and natural aroma, and is deeply loved by consumers. Navel oranges have a rot rate of up to 30% during storage and transportation, which brings huge losses to fruit farmers and is also unfavorable for the promotion of Gannan navel orange industry. The main factors leading to mildew in navel oranges are microbial action, bad weather and problems in the picking process. [0003] Chitosan is easy to dissolve in a weak acid solvent, and the dissolved solution contains amino groups, which can inhibit the growth of bacteria by combining negative electrons. Chitosan can inhibit the activity of bacterial growth, so it has a wide range of applications in the fields of medicine, textile and food. In addition, chitosan and its derivatives have goo...
