Utilization of Minor Millets for Tempeh Production

An experiment was carried out for the utilization of minor millets (little foxtail and finger millet) with the soybean and horse gram for millet tempeh production. Rhizopus microsporus var oligosporus was grown satisfactorily on the substrates. At 35°C fermentation was completed within 39.50 hours compared to 30°C (53.14 hours). The pH, which was adjusted at about 5.2-5.5 with acetic acid in the substrates and during fermentation, raises progressively upto 48 hrs of incubation period to above 7.1-7.3, which was maintained constantly. The Acid protease activity was found to be increased with increase in time intervals upto 36 hrs beyond which, it decreased significantly. But, Acid protease activity was significantly highest at 350C as compared to 30°C.
