Abstract:
Soybean is a high-purine food, in order to reduce the purine content of whole soybeans,this study soaked soybean with different conditions, the perchloric acid hudrolysis was used to extract the purines and their compounds and the purine content of soybean was determined by HPLC to study the influence of soaking conditions on purines and their compounds. The method of single factor and orthogonal experiment were used to optimize the technological conditions. The results showed that under the soaking conditions which including addition of calcium chloride 4%( g:mL),soaking temperature 60℃, soaking time 2.5 h,the ratio of material to liquid 1∶5(g∶mL), the removal efficiency of total purine in whole soybean was the best, which declined from 1.645 mg?g-1 to 1.199 mg?g-1. The removal of the main purine compounds were small molecule purines, the macromoleculars were not easy to dissolve from soybean. The loss of nutrients in the treated soybean was small and the overall sense was good.
