Abstract

The invention discloses a composite plant mildew preventive for unhusked rice and a preparation method of the composite plant mildew preventive. The composite plant mildew preventive is prepared fromthe following raw materials of 100-120 parts of litsea cubeba, 100-120 parts of fructus psoraleae, 100-120 parts of fructus cnidii, 200-250 parts of sapindus mukorossi and 600-750 parts of distilled water. Instruments required for preparation comprise a high-speed universal crusher, an ultrasonic cleaning instrument, a multi-pipe-frame automatic balancing centrifugal machine and a constant-temperature oscillator. The preparation process comprises the following main steps of ultrasonically cleaning, drying and crushing raw materials, adding the distilled water into sapindus mukorossi dry powder, performing full and uniform stirring, performing ultrasonic extracting, performing centrifugal separating, and taking supernatant; and mixing the litsea cubeba, the fructus psoraleae and fructus cnidii dry powder with the sapindus mukorossi extracting solution, and performing constant-temperature extraction to obtain the composite mildew preventive. According to the method, effective antibacterial components extracted from natural plants are used as natural preservatives of grains, so that the composite plant mildew preventive not only can resist bacteria and prevent corrosion, but also canenhance the fragrance of the grains.

Description

technical field [0001] The invention belongs to the technical field of mold prevention, and in particular relates to a compound plant mold inhibitor for paddy and a preparation method thereof. Background technique [0002] The main rice production and storage areas in my country are located in the south of the Yangtze River. The south of the Yangtze River is in a monsoon climate with high temperature and heavy rainfall, which is very easy to cause the growth and reproduction of microorganisms and pests. cause severe loss. [0003] Mycotoxins are toxic secondary metabolites produced during the growth of molds, and are widely found in feed, feed ingredients and human food. Enter human and animal body through food or feed, cause acute or chronic poisoning of human and animal, damage the body's liver, kidney, nerve tissue, hematopoietic tissue and skin tissue, etc. Feeding moldy feed can not only directly cause poisoning death of livestock and poultry , but also endanger human ...
