24 soybean varieties from three northeastern provinces and Inner Mongolia Autonomous Region were selected for yuba processing,and the physical and chemical parameters of different soybean varieties,as well as the yield,rehydration,dry matter loss rate of yuba were analyzed,the relationship between the soybean varieties physical and chemical characteristic and yuba quality parameters was investigated.The results showed that there were a big differences in the quality and yield for yuba production with different varieties of soybean.The amplitude of yuba yield,rehydration,and dry matter loss rate were 35.72% to 45.18%,127.34% to 274.54% and from 3.85% to 6.75%.Physical and chemical characteristics and the yuba yield and quality parameters were closely related to soybean varieties.Yuba rehydration was highly significantly negative correlated with the fat content of soybean varieties,but yuba yields was significantly positive correlated with the fat content of soybean varieties.The protein content of soybean varieties was significantly negative correlated with yuba dry matter loss rate,but significantly positive correlated with yuba rehydration.
