自然冷资源条件下低温储藏仓储藏稻谷的试验研究
Storage Character of Rice by Using Natural Cold Source Storage Warehouse
摘要
Abstract
The experiment was designed to solve the postponed q uality deterioration of rice by ordinary temperature storage method and to achieve the optimum storage conditions of rice at low temperature storage condition. In this research, rice was stored in natural cold source storage, and the fatty acid value, germination rate and total numbers of fungi of rice were evaluated at every end of the month from May to September. The rice storage experiment was designed in 2 factors with 3 levels, i.e. 3 storage temperature levels (5, 10 and 15 ℃) and 3 rice moisture content levels (15.0, 16.5 and 18.0%). A suitable combination of storage temperature and rice moisture content of storage characters was obtained by using comprehensive evaluation. The regression equations of fatty acid value, germination rate and total number of fungi were established by using SPSS software and the rice storage verification test was carried out according to the optimization results. The results showed that the natural cold source warehouse was cooled stability at low temperature during storage period. Storage temperature and moisture content of rice were positively correlated with fatty acid value and total number of fungi (p<0.05), and negatively correlated with germination rate (p<0.05). A comprehensive method of assessing storage characters of rice was established using a membership function method and the optimum storage conditions were the storage moisture content of 16.5% and storage temperature of 10℃. The rice storage verification test was carried out with the optimum storage condition of rice in natural cold source warehouse from May to September in the next year. The verification test result showed that the final fatty acid value in rice was 18.3 mg?(100g)-1, that the final germination rate was 86.75%, and that the final total number of fungi was 5.1×104CFU?g-1. This study provided a theoretical foundation for the application of natural cold source technology in large scale rice storage.关键词
