Problems solved by technology

Generally speaking, materials such as chitosan and plant polysaccharides used in traditional coating technology are expensive, and they are also organic matter, which may become a medium for the growth of some fungi. In addition, the film-forming effect is seriously affected by the humidity of the storage environment, and the protectiv

Abstract

The invention discloses a fresh bamboo shoot cut protecting agent containing inorganic nanometer active components, and a method. The cut protecting agent consists of the following components in partsby weight: 20-30 parts of food-grade calcium hydroxide powder, 69.2-79.8 parts of food grade calcium carbonate powder and 0.2-0.8 part of nanometer silicon dioxide powder. Before being used, the protecting agent is uniformly mixed with water in the weight ratio of the protecting agent to the water being 1 to (2-3), blending is performed so that pulp is obtained, the pulp is applied to the surfaceof a cut which is subjected to cleaning, disinfecting and air-drying, the cut after being applied with the pulp is aired, and the fresh bamboo shoot cuts are stored. Compared with other bamboo shootfresh keeping agents, the preparation namely the fresh bamboo shoot cut protecting agent consists of inorganic components and nanometer components, does not contain chemical sterilization agents, hasthe fresh-keeping effects through pH environment regulation and the physical bacteriostasis effects of nanometer materials, is high in safety, low in cost, simple and convenient to operate and good inprotection effects, and can effectively prevent bamboo shoots from losing weight during storage and effectively prevent the cuts from decomposing and generating mildew and rot.

Description

technical field [0001] The invention belongs to the technical field of fruit and vegetable damage protection, and in particular relates to a fresh bamboo shoot cut protection agent containing inorganic nanometer active ingredients and a method thereof. Background technique [0002] Bamboo shoots are rich in nutrition and are deeply loved by consumers. However, due to high water content, fast metabolism, and warm and humid harvest season, bamboo shoots are very easy to rot. At present, the patented bamboo shoot preservation technology that has been published or authorized mostly uses whole bamboo shoots. For example, application number CN201710493932.8 discloses a preservation method similar to canned food through precooking, packaging and sterilization of bamboo shoots; application number CN201610442326.9 adopts preservation liquid Fresh-keeping methods of immersion, ultraviolet irradiation, heat shock treatment, and refrigeration after heat dissipation; application number ...
