Study on Standardization of Fermentation Time for Foxtail Millet to Blackgram

Abstract

Fermentation is an easy and economic food processing method used to prepare desirable convenient foods. Instant or ready to use dosa mix from foxtail millet, rice and pulses (black gram and green gram) at 37°C with fermentation intervals of 6, 12 and 18 hours depending upon the pulse were analysed. Different combinations were prepared by mixing these ingredients in various ratios like 70% foxtail millet, 20% black gram, 10% green gram or 50% foxtail millet, 20% rice, 30% black gram and 10% green gram or 50% foxtail millet, 20% rice, 20% black gram, 10% green gram and control of 70% foxtail millet and 30% black gram. The results revealed that 12 hours of fermentation was necessary to give best dosa for all combinations and control. The first combination gave better results when compared with control and the percentage increase in appearance, texture, flavour and overall acceptance were 3.66%, 2.41%, 1.18% and 1.19% respectively with decrease in taste by 7.53% and no change in sourness for both samples.
