Nutrient profile of porridge made from Eleusine coracana (L.) grains: effect of germination and fermentation

Porridge ( koozh ) is one of the traditional foods made from Eleusine coracana L. grains (Finger millet). It is a soft food prepared from processed (germinated & fermented) finger millet flour (FMF). However, in the modern world of fast food, koozh is usually prepared from non-processed (non-germinated & non-fermented) FMF. Hence, present study was undertaken to evaluate the macro and micro nutrient contents in koozh prepared from germinated (fermented & non-fermented) and non-germinated (fermented & non-fermented) FMF. Highest protein, carbohydrate and glycoprotein contents were found in koozh prepared from germinated & non-fermented FMF. The free amino acid contents are higher in germinated & fermented condition when compare to other preparations. No significant change was observed in the calorific value of all preparations. There is no statistical difference in macro-nutrients & micro-nutrients minerals such as calcium, iron, magnesium, manganese, phosphorous and zinc among all the preparations. However, copper content is higher in non-germinated condition, whereas selenium, silicon and sulphur are higher in germinated FMF when compared to others. Significant level of total phenol, total flavonoid and free radical scavenging activity was observed in all preparations, which increased further during fermentation. The present observations, lead us to conclude that koozh prepared from germinated & non-fermented FMF contains higher level of carbohydrate, protein and glycoprotein, however germinated & fermented koozh has increased aminoacids, phytochemicals and free radical scavenging activity. Hence it is suggested that the consumption of koozh made from germinated & fermented FMF may provide easily digestible and energetic nutrients for healthier life.
