Problems solved by technology

However, the former has potential safety hazards because it is difficult to clean fruits and vegetables when they are eaten, and sometimes causes intestinal infections; while the traditional corrugated boxes mentioned in the latter are due to the complexity of the process, high manufacturing costs, and no functional fresh-keeping components in the inner layer. , it can only achieve a limited fresh-keeping effect in the end, and has not been widely promoted and applied in the market

Abstract

The invention discloses a fruit and vegetable antistaling coating, which is composed of the following raw materials (by weight): 1 part of an ethylene absorbent, 100-200 parts of an adhesive, 0.1-10 parts of a water regulator and 0.05-15 parts of an antibacterial agent. A preparation method of the fruit and vegetable antistaling coating is simple; manufacturing cost is low; antistaling function is good; and the formula used has good safety, has no residue, can be used for directly packaging fruit and vegetable products, and has strong market competitive superiority.

Description

(1) Technical field [0001] The invention relates to a fresh-keeping paint, in particular to a fresh-keeping paint for fruits and vegetables. (2) Background technology [0002] During the entire logistics process of fruit and vegetable harvesting, storage, transportation, and reaching consumers, if the preservation is not done properly, it will cause losses after harvesting. In order to adjust the market supply, it is necessary to properly preserve the freshness of the fruits and vegetables after harvesting. processing to meet people's needs. [0003] Over the years, in order to keep fruits and vegetables fresh during storage and transportation, researchers have successfully developed a variety of preservation methods and technologies based on the physiological and physical characteristics of fruits and vegetables. On fruits and vegetables, or dilute the preservative with water to form a fresh-keeping liquid, soak the fruits and vegetables for a period of time, dry them befo...
