Abstract

The invention relates to apple fresh-keeping liquid as well as a preparation method and application thereof. Effective components are dissolved into an acetic acid solution with the volume concentration of 1 to 5 percent to prepare a viscous colloidal solution with the mass concentration of 10 to 30 percent; the effective components comprise the following components in parts by weight: 15 to 30 parts of shenqinmycin fermentation filtrate, 5 to 10 parts of an eggplant peel extracting solution, 10 to 20 parts of chitosan, 5 to 10 parts of corn starch and 15 to 30 parts of distilled water. Compared with the prior art, the apple fresh-keeping liquid provided by the invention is safe, green and environmentally friendly; instruments and equipment are simple and utilized reagents are cheap and easy to obtain; industrialized production and popularization and application in the market are convenient to realize, and the potential safety hazard problems of pesticide residues, toxicity and the like; chemical pesticide or preservatives are not needed, and long-time fresh keeping can be realized.

Description

technical field [0001] The invention relates to the technical field of fruit fresh-keeping, in particular to an apple fresh-keeping liquid and its preparation method and application. Background technique [0002] Apple fruit is spherical, mild in nature and flavor, crisp in taste, and rich in carbohydrates, vitamins and trace elements, organic acids, pectin, protein, calcium, phosphorus, potassium, iron, vitamin A, vitamin B, vitamin C and dietary Fiber, which also contains malic acid, tartaric acid, and carotene, is the closest to perfect nutritional value among all fruits and vegetables, so it has the title of "King of Fruits". China is the world's largest apple producer, accounting for more than 50% of global apple production, and its apple exports rank among the top in the world. In 2016, my country's apple production was 43.88 million tons, which is the largest fruit variety in my country (excluding melons). However, due to the seasonality and regionality of apple pro...
