早稻在收获季节,往往遇阴雨等原因,得不到及时干燥,造成霉变、堆黄损失.各地农村均有发生.现在对稻米含黄率的多少与黄曲霉毒素B_1含量的高低不呈正比关系的认识,应该说是基本解决了,但对变黄后的潮谷,是否比正常潮谷容易受黄曲霉毒素污染和污染的期限规律问题,研究尚少,为保障人民食用卫生,合理利用变黄稻米,我们于1981、1982年的两年中,在近郊早稻收获季节,将脱粒潮谷在室内堆积变黄后,立即薄摊降温,探索黄曲霉菌的侵染与产毒的发展过程,现将研试情况与结果报告如下:
Early rice in the harvest season, often Yu rain and other reasons, not timely drying, resulting in mildew, yellow pile loss occurred in rural areas have occurred now about the number of rice yellow rate and aflatoxin B_1 level is not proportional The understanding of the relationship should be said that the basic solution to the tide Valley after the yellow is more than normal tide valley susceptible to aflatoxin contamination and pollution of the deadline law, the research is still less, in order to protect people’s food hygiene, rational use of Yellowing of rice, we in 1981 and 1982, two years, in the suburbs of early rice harvesting season, the threshing trough indoors after the accumulation of yellow, cool down immediately to explore the development of Aspergillus flavus infection and toxigenic development , Now the research situation and the results reported as follows:
