Problems solved by technology

[0005] However, the mold remover was used late in our country, and there is no corresponding national standard, so the use effect is very different.
At the same time, due to the complex composition of the mold remover, it is difficult to guarantee the safety; further, after being treated with the mold remover, it can only have the effect of adsorbing toxins, and mold may still exist

Embodiment 1

[0051] Take an appropriate amount of corn with different degrees of mildew, and the UV intensity is 6.6kJ / m 2 Under the condition of irradiating for 10min;

[0052] Place the mildewed corn after the ultraviolet treatment and the attapulgite with a particle size of 150 mesh in a closeable container according to a mass ratio of 1:1; close the container, place it on a shaker, and mix it thoroughly for 10 minutes;

[0053]Then, the corn and the attapulgite are sieved and separated, the treated corn is collected, and the AFB1 content in the treated corn is detected and recorded;

[0054] The process of treating corn with attapulgite is as follows figure 1 shown.

[0072] (1) Effect of different meshes and different proportions of attapulgite on AFB in moldy corn 1 Clearing effect experiment

[0073] with AFB 1 The moldy corn with a concentration of 84.41±3.94μg / Kg was used as raw material, and treated with attapulgite with different mesh numbers and mass ratios. The treatment method is as follows: put a certain mass ratio of attapulgite and moldy corn into a closeable container; close the container, place it on a shaker, and mix it thoroughly for 10 minutes; then, sieve the corn and attapulgite to separate, collect For the treated corn, the AFB1 content in the treated corn is detected and recorded.

Abstract

The invention provides a method of compound treatment of moldy grain. The method comprises the following steps that the moldy grain is treated through ultraviolet rays and attapulgite; an attapulgiteand ultraviolet compound system is adopted for treating the moldy grain, on the one hand, pathogenic bacteria and toxins in the moldy grain can be adsorbed through attapulgite, and meanwhile the removing efficiency of fungal viruses can be improved through the ultraviolet effect; on the other hand, long-acting sterilization is facilitated, and the quality guarantee period of the treated grain is prolonged; meanwhile, by means of the compound effect of two different treatment ways, the moldy grain can be subjected to mold removal and detoxification more effectively, and the grain loss is reduced.

Description

technical field [0001] The invention relates to the field of grain storage, in particular to a method for composite treatment of moldy grain. Background technique [0002] China is a large agricultural country with large grain reserves, but the deterioration of grain quality caused by mildew is serious, which has brought great hidden dangers to the quality and safety of grain in our country. [0003] The proportion of food contaminated by molds in the whole world is 5-7% every year, and the loss of agricultural products and industrial raw materials caused by moldy pollution mycotoxins reaches tens of billions of dollars every year. According to the statistics of the FAO, nearly one-third (about 1.3 billion tons per year) of the global food production for human consumption suffers from loss and waste. [0004] In order to solve the food loss caused by mildew, researchers have also developed a variety of grain anti-mold products, for example, using montmorillonite as a mildew...
