ABSTRACT
Wheat (T1) and maize (T2) based sattu were formulated using chick pea, barley and other food adjuncts. Results revealed that, no significant difference was observed in the protein and ash content between control (chickpea basede sattu mix) and T1. However, significant difference was observed between the control and T2 sample between moisture, fat, insoluble and total fiber, with the exception of protein, soluble fiber and ash. In case of T1 and T2, significant difference was observed in fat and total fiber content. Coming on to the mineral composition, significant difference was observed between the mineral content in control and T1, with respect to calcium, potassium, sodium, magnesium, iron, manganese and copper. In case of control and T2, significant difference was observed with respect to calcium, potassium, sodium, magnesium, iron and copper, with the exception of manganese. Coming on to the mineral content of both the formulations, significant difference was observed with respect to all the minerals estimated. Significant difference was observed in the total amylose content between control and formulated samples on 0, 30 and 60 days. Microstructural studies of raw and roasted sattu and its ingredients by observation under scanning electron microscope revealed that substantial structural changes occurred during processing. The raw grains were tightly packed and contained no air spaces. However, a large number of air spaces are formed in the cotyledon of the roasted grain sample. It was observed that, T1and T2 had medium GI value (56 and 58% respectively), Whereas for control it was 60%. The formulated samples were found to be shelf stable for 60 days at RT, with an increase in moisture content of 4-6%. All the samples were sensorial acceptable and there was no perceptible off odor or off taste.
