Effect of supplementation of wheat flour by soymilk on chemical, biological and sensory evaluation of produced biscuit.

Abstract: ABSTRACT
The present study was carried out to investigate the effect of replacement of wheat flour (72% ext.) by 15% soymilk powder (SMP) or fermented soymilk powder (FSMP) on the quality of the produced biscuit and the effect of such replacement on osteoporosis status of ovariectomized female rats. The obtained results could be summarized as follows:
Chemical composition of biscuits of 15% soymilk or fermented soymilk powders lead to an increase in protein, fat, ash and mineral content. Isoflavones contents in biscuits was also determined.The results showed that biscuit contained 15% fermented soymilk powder is the richest product of daidzein and genistein than biscuit contained 15% soymilk powder.Sensory evaluation results indicated that addition of soymilk or fermented soymilk powders at 15% could be recommended for production of biscuits. Results of the biological experiment showed that biscuits contained 15% soymilk or fermented soymilk powders caused no significant differences in serum ca and p concentrations in both of ovariectomized and normal rats. On contrary, serum alkaline phosphates activity was higher in ovariectomized rats fed on diets containing SM and FSM powders compared with those found in rats fed on a basal diet or control biscuit. The femoral bone lengths were also taller in ovariectomized rats fed on diets containing SM and FSM powders than normal rats taking the same diets. Breaking forces of rats femurs were slightly higher in normal rats and ovariectomized rats fed diets containing soymilk and fermented soymilk powders compared with femurs of those fed on the diet control biscuit. On the other hand, bone density and bone mineral density values were elevated in ovariectomized rats fed on the tested diets (SM and FSM powders) compared with those fed on a basal diet or control biscuit.
