Storage, sterilization and pest preventing freshness-keeping film for broad bean, and preparation method thereof

Abstract

The present invention discloses a storage, sterilization and pest preventing freshness-keeping film for broad bean, and a preparation method thereof, and belongs to a protective measure for broad bean pest damage. The freshness-keeping film comprises, by weight, 0.2-0.5% of chloropicrin, 0.3-0.5% of aluminium phosphide, 3-4% of a mixture comprising flatspine pricklyash oil, cinnamon oil and porous starch, 1-2% of polyethylene wax, 0.5-1% of glycerol monostearate, 0.5-0.7% of oleamide, 2-3% of calcium carbonate, and 62.3-72% of a low density polyethylene resin. According to the present invention, the storage, sterilization and pest preventing freshness-keeping film for the broad bean is prepared by adopting commonly used sterilization and pest preventing components, the production process is simple, the existing equipment can be adequately adopted to process and produce the film according to the ratio of various components of the freshness-keeping film, the freshness-keeping film can further be used for provision of storage and pest preventing for other grains, and the application range is broad.

Description

technical field [0001] The invention relates to a protective measure against broad bean pests, in particular to a broad bean storage sterilization and insect-proof fresh-keeping film and a preparation method thereof. Background technique [0002] Doubanjiang is called the soul of Sichuan cuisine. There are more than 350 million people in the country who eat Doubanjiang. The annual production and consumption of Doubanjiang is huge. As one of the raw materials of Doubanjiang, the consumption of broad beans is also very large. During the preservation of broad beans, they are often eaten Erosion by pests such as broad bean gnats also greatly reduces the edible quality and nutritional value of broad beans, bringing serious economic losses to enterprises, and at the same time bringing safety hazards to the deep processing of broad bean food production in the later stage. Spray sterilizing and insect-repelling liquid on broad beans or other grains to achieve the purpose of killing ...

[0002] Doubanjiang is called the soul of Sichuan cuisine. There are more than 350 million people in the country who eat Doubanjiang. The annual production and consumption of Doubanjiang is huge. As one of the raw materials of Doubanjiang, the consumption of broad beans is also very large. During the preservation of broad beans, they are often eaten Erosion by pests such as broad bean gnats also greatly reduces the edible quality and nutritional value of broad beans, bringing serious economic losses to enterprises, and at the same time bringing safety hazards to the deep processing of broad bean food production in the later stage. Spray sterilizing and insect-repelling liquid on broad beans or other grains to achieve the purpose of killing pests. However, in actual operation, broad beans or other grains are stored for a long time. It also increases the workload of broad beans or other grain storage management, and more importantly, the liquid medicine will also damage the quality of broad beans or other grains, and will also bring safety hazards to later food deep processing production, so it is necessary to address this One defect for further improvement
