Moisture, carbohydrate, protein, fat, calcium, and zinc content in finger, foxtail, pearl, and proso millets

Abstract

BACKGROUND: Millets are a group of variable small seeded grass, widely grown around the world as cereals crop. The finger millet had more moisture and calcium content. Whereas, fat content was least when compared to three other different millets. Foxtail millets had more protein content, pearl millets had more zinc and proso millets had more carbohydrate and fat content. AIM: To determine the proximate constituent and micronutrient content of finger millet, foxtail millet, pearl millet and proso millet. OBJECTIVES: To analyse the moisture, carbohydrate, fat, and protein content of finger millet, foxtail millet, pearl millet, proso millet by standard methods of AOAC. To analyse the calcium and zinc content of finger millet, foxtail millet, pearl millet, proso millet by atomic absorption spectrophotometer.MATERIALS AND METHODS: Proximate analysis of samples (moisture content, carbohydrate, protein, fat, calcium and zinc) was performed by standard methods of Association of Official Analytical Chemist (AOAC).RESULTS AND CONCLUSION: The mean values of finger millet for moisture content (12.86 ± 0.95) had highest and fat content (1.58 ± 0.36) was least. In foxtail millet protein content (12.94 ± 0.87) was highest and in pearl millet zinc content (3.29 ± 0.47) was highest. In proso millet fat content (12.80 ± 0.30) and carbohydrate content 75.06 ± 7.3) was highest when compared to the other millet. Calcium (344.45 ± 2.62) had highest in finger millet whereas pearl millet zinc content (3.29 ± 0.47) was highest when compared to the other millets. Hence, the study results can be useful for informing the people to select the different millets depending upon the nutritional needs.
