The Soybean (Glycine max L.) variety JS-97 52 used for preparation of soy milk & tofu (Soy paneer). Tofu and soy milk producers prefer the higher protein cultivars. The shelf life of tofu is very less therefore to extend it, effect of different doses of gamma radiation on physical & hunter colour of tofu using packaging material as BOPP, HDPE and LDPE at 0, 5, 10, 15, 20 days have been studied. The Hunter colour L, a and b value of tofu shows that the colour of tofu varies from light creamy with fine yellow colour. As earlier researchers stated that colour of product changed after irradiation. In this finding seems to be that effect of radiation may be due to removal of water. The biomolecules may also undergo for conformational changes due to radiation which may cause the variation in the concentration during storage. | Studies on physical and hunter colour of gamma irradiated tofu (Soy Paneer)
