Abstract

To study the level of oligosaccharides present in selected Asian Indian minor millets such as Varagu (Paspalum scrobiculatum), Samai (Panicum millare) and  Thinai (Setaria italica) and the effect of germination on their oligosaccharide content. The select Asian Indian minor millets were obtained from local market and subjected to germination. The germinated and ungerminated samples were analysed for raffinose, stachyose and maltotetraose by extraction with hot water followed by High Pressure Liquid Chromatography analysis. The high oligosaccharide content (5 to 10%) was found in Thinai (Setaria italica). Raffinose content was around 8.5-12% in almost all minor millets. The oligosaccharide content in germinated minor millets reduced significantly due to enzymatic breakdown into simple sugars.
