Probiotic fermented foods are fast being recognized as health foods. Most of such foods are based on dairy products but little research work is available on coarse cereals and millets, which constitute the staple foods in developing countries. This paper aims to determine the effect of germination and fementation on nutrient composition of pearl millet based food blends.
Indigenously developed pearl millet based food blends containing raw and germinated pearl millet flour, whey powder and tomato pulp (2:1:1w/w) were autoclaved, cooled and fermented with 5 percent Lactobacillus acidophilus curd which supplied 106cells/ml to the slurry at 37°C for 12 h. The unfermented blends, after autoclaving, served as controls. The developed food blends were subjected to nutritional evaluation by using the standard methods of analysis. The data were statistically analysed.
Pearl millet based, germinated, autoclaved and fermented, food blend maintained adequate cell viability (8.64 cfu g‐1) as compared to non‐germinated food blend. Germination and probiotic fermentation caused significant improvement in the contents of thiamine, niacin, total lysine, protein fractions, sugars, soluble dietary fibre and in vitro availability of Ca, Fe and Zn of food blends.
Research is currently aimed at developing probiotic millet based food mixture, which had enhanced nutrient profile. Hence, it can be considered for commercialization after establishing its health/therapeutic implications among the population.
Dairy foods have preferentially been used as the carrier medium for probiotics. This paper explores the possibility of using staple foods as the carrier medium. The consumption of such food mixtures containing viable probiotic bacteria should be enhanced among consumers in term of their role in health maintenance and disease prevention.
