摘要
优质籼稻在储藏期间品质容易发生改变,色泽的变化更是明显,而发生黄变的两个主要因素是微生物和环境条件.通过设置不同的水分含量和储藏温度,考察灰绿曲霉、黄曲霉、白曲霉和黑曲霉4种主要霉菌对优质籼稻黄变的影响.研究结果表明:在不同水分含量和储藏温度条件下,优质籼稻的黄度指数发生了不同程度的改变,其中单一接种灰绿曲霉水分含量为17%的优质籼稻在30 ℃储藏温度下,黄度指数增加最快;由带菌量和黄度指数的相关性分析得出4种霉菌分别在适宜的生长环境中,对黄变影响程度最大的为灰绿曲霉,最弱的为白曲霉.研究结果为储藏过程中稻谷黄变及预防提供了理论依据.
Abstract
The quality of high-quality indica rice is prone to change during storage,especially its own col-or.The main two factors of yellowing of high-quality indica rice are microbial and environmental condi-tions.In this paper,the effects of four main molds:Aspergillus glaucus,Aspergillus flavus,Aspergillus al-bicans and Aspergillus niger on the yellowing of high-quality indica rice were investigated by setting differ-ent water conditions and storage temperatures.The results showed that the yellowness index of high-quality indica rice changed to varying degrees under different conditions.Among them,high-quality indica rice with a water content of 17%was inoculated with Aspergillus glaucus at 30 ℃ for simulated storage,and the yellowness index increased the fastest.From the correlation analysis on the number of bacteria and the yel-lowness index,it was concluded that Aspergillus glaucus had the greatest influence on the yellowing in the suitable growth environment,and the weakest was Aspergillus albicans.
