Variation of tofu yield and qualities of soybean globulin subunit mutants/
Four soybean germplasm with typical variation in soybean 7S, 11S globulin subunit composition were used to make tofu by mini-specimen soybean processing method. The tofu yield, dry tofu weight (DTW), protein content (PC), hardness of tofu and ratio of protein amount in soybean milk to total protein amount (RPA) were examined, and the four soybean germplasm's potential usability of tofu quality processing were analyzed .The results indicated the tofu made from riA-5 with αt-subunit null, riB-1 with [(αt+ α) + 11S(ll b + ll a)]-subunit null and Yuenanheqi with β-subunit extremely low had significant variation in tofu yield, DTW, PC, hardness of tofu, RPA and other quality traits. The genetics variation coefficient of wet weight and dry weight of tofu among four experiment materials was bigger. The riA-5 with αt-subunit null was suitable for tofu production which takes CaSO4 as the coagulator. The tofu made from riB-1 with low 7S globulin and deficiency of 11S globulin acid subunit had smaller hardness of tofu and bad tofu shaping and appearance quality. The Yuenanheqi with β-subunit extremely low could be used as choosing parents for breeding good quality tofu.
