Problems solved by technology

Although artificially synthesized chemical anti-mold preservatives have inhibitory effect on mold, they have poor broad-spectrum, high cost, high toxicity, and there are industrial waste problems, which are easy to pollute the environment. For example, anti-mold agents such as sodium benzoate have been used by many The country strictly limits the use of
The relevant toxicological evaluation of some chemically synthesized anti-mold preservatives has not been completed, and there are certain potential safety hazards

Embodiment 1

[0008] Embodiment 1: the inhibitory effect of sorbaldehyde on the contamination of Aspergillus flavus in corn storage

[0009] Select corn seeds with full grains and no mold contamination, disinfect with 1% sodium hypochlorite solution, rinse with sterile water, and finally dry the surface of corn seeds with sterile filter paper. To adjust the desired moisture content, maize seeds were soaked in a freshly prepared suspension of A. flavus spores for 30 seconds, and the surface moisture was blotted dry with sterile filter paper. For each fumigation concentration, 10-15 corn seeds treated by the above steps are evenly placed in a sterile glass bottle. Dilute sorbaldehyde 2 times with n-hexane, use a micro-sampler to accurately draw different volumes of the mixed drug solution and drop it on the sterile filter paper carrier on the inner wall of the bottle cap, quickly screw the cap and seal it with a profile film, and place it at 28±2 Cultivate in a constant temperature incubator...

Abstract

The invention discloses an application of sorbaldehyde as a natural anti-mould agent in grain storage, and aims to control the pollution of biological harmful factors such as poisonous fungi and mycotoxins generated in a grain storage process. The invention relates to the technical field of grain mould prevention, in particular to the use of sorbaldehyde as a natural anti-mold agent, controls theharm of harmful mould such as aflatoxin in the storage process of grains such as corn and peanuts so as to prevent or reduce the pollution of the mycotoxins such as the aflatoxin in the grains, and ensures the edible safety of grains serving edible and processing applications. The sorbaldehyde (E, E-2, 4-Hexadienal) used in the present inventio is a micromolecular volatile substance which naturally exists in plants, has the advantages of strong bacteriostatic activity, good volatility, high safety, gas phase bacteriostasis, convenient use and no residue, and meets people's requirements of green, safty and environmental protection of grain anti-mould agents.

Description

technical field [0001] The invention relates to a natural grain antifungal agent, in particular to sorbaldehyde (CAS No.: 142-83-6) used as a natural antimold agent to control the harm of corn, peanuts and other grains during the storage process of harmful molds such as Aspergillus flavus, Eliminate or reduce the contamination of mycotoxins such as aflatoxin in food. Background technique [0002] In the process of grain storage, under certain environmental conditions, microorganisms can multiply and grow rapidly and cause grain deterioration. Even if the storage conditions are good, microorganisms can grow slowly, which can also change the color, flavor, and quality of the food, thereby reducing the food quality and safety of the food. With the increasingly prominent food safety issues, mold contamination of food has attracted more and more public attention. The safe production, circulation, and sales of food are closely related to the lives of the public, and are one of t...
