Dosa is a thin, crispy, texture and desirably sour flour. The dosa is a power packed healthy breakfast or snack for all ages. It is a rich source of proteins, carbohydrates. Rice has been used in many countries (Malaysia, China) for medicinal purpose. In chinesh believe, rice strengthen the spleen, weak stomach, increase appetite and also rice has the capability to enrich body elements, to regulate blood pressure, to prevent skin disease. In Kerala, the Navara is believed to have medicinal property and is used to increase semen, fertility, increase the weight of foetus, increase the mother milk and it also a remedy for Rheumatism and Neural disorders. The dosa mix was prepared with Navara rice, legumes like black gram, Bengal gram, green gram, spices, medicinal leaves like Tulasi, Modakkarthan etc. The Proximate analysis of Navara Dosa mix have high amount of Protein and Fibre when compare with Navara Rice and also the Navara dosa with leafy material shows low hardness (64.682), stickiness (−1.005) and stringiness (13.269). The growth of microorganisms can be inhibited or killed by some active compounds. These are called antimicrobial activity. Aspergillus flavus is a mould and some stains are producing large amount of Aflotoxin. The inhalation of spores causes bronchial and pulmonary infection of man. E.coli is a gram negative, rod shape bacteria. It is found in gut of human. It can be an opportunistic pathogen causing Pneumonia, and urinary infection. The antimicrobial activity was studied by KirbyBauer disc diffusion method. The Zone of inhibition was 25mm for A.flavus and E.coli, due to the combine of Navara rice, legumes, spices and medicinal leaves. Hence, the dosa mix has implication for preventing or treating infections caused by microorganisms. The Navara dosa mix have high amount of protein content and also have low amount of fat content due to the addition of leafy materials and pulses. This is used for the growth of children. From this study it is inferred that Neutraceutical and also healthy break fast food for human and children.
