| Abstract: |
| In order to explore the changing cycle of soybean storage quality in three grain storage ecological regions in China and guide the technical measures of soybean quality preservation in different grain storage ecological regions. Soybean quality data from relevant storage points during 2014-2016 were collected, the changes in crude fat acid value and protein solubility ratio during storage of soybeans were examined, and the correlations between soybean quality indexes and crude fat acid value, protein solubility ratio were analyzed. The results showed that regional storage temperature had obvious effect on crude fat acid value of soybean, but had little effect on protein solubility ratio. Storing soybeans in the fifth areas with moderate temperature and high humidity had a certain relationship with the increase of crude fat acid value and the increase of damaged grains, heat damaged grains, and storage time. There was a certain relationship between protein solubility ratio and heat damaged grains. In conclusion, reasonable control of damaged grain ratio and heat damaged grain ratio of soybean has obvious effect on controlling crude fat acid value and protein solubility ratio. |
