Abstract

The research was conducted at Agricultural College & Research Institute, Vazhavachanur of Tamil Nadu, India during the period from June 2019 to May 2022. In the study, five different millets and two varieties of each cultivated in and around Tiruvannamalai district of Tamil Nadu as the test cereal grains in completely randomized design with three replications were tried. Biochemical estimations were carried out to study the nutritional and mineral status in foxtail millet (ATL1, CO (Te) 7), kodo millet (CO 3, TNAU 86), little millet (CO 4, ATL1), barnyard millet (MDU 1, CO (KV) 2) and proso millet (ATL 1, CO (PV) 5). Simultaneously anti-nutritional factors were also quantified for the same grain samples. Results showed that Proso millet, variety ATL 1 has recorded the highest percentage of crude protein i.e. 12.2% and total protein 11.0% at moisture content 11.42% among the millets tested. Little millet, variety ATL 1 has recorded the highest carbohydrate content (71.2%) and starch content (69.2%) at moisture content 9.02% among the millets tested. Barn yard millet, CO 2 has recorded the highest percentage of amylose i.e. 29.3 g/100g starch and highest percentage of Resistant Starch i.e. 5.3 g/100g starch. Barn yard millet, variety MDU 1 has recorded the highest content of total phenols i.e. 14.40 mg/100g at moisture content 8.73%. Barn yard millet, MDU1 has recorded the highest Total flavonoids content i.e. 6.78 mg/100g. Proso millet, variety ATL 1 has recorded the negligible quantity of Tannin content i.e. 0.06mg/100g. Little millet, variety ATL 1 has recorded the lowest quantity of Phytic acid content i.e. 23mg/100g. Results revealed about a considerable variation in levels of different Biochemical traits due to the nature of minor millets and also based on the genotypes. The biochemical information’s on non-protein nitrogenous compound percentage, resistant starch percentage and carotenoid content, ratio of total phenol and total flavonoid, tannin content were not mentioned clearly in the previous literature. This study gives the information clearly. The overall results of this study revealed that Proso millet, variety ATL 1 and Barn yard millet, varieties CO 2 and MDU1 were considered as top three minor millets among the tested sources.

Conclusion

There was a significant variation in the nutritional and antinutritional profile of selected minor millets. Variation in levels of Biochemical traits in minor millets is due to their nature and also based on the genotypes.The overall results of this study revealed that Proso millet, variety ATL 1and Barn yard millet, varieties CO 2 and MDU1 were considered as top three minor millets among the tested sources. Millets can be used as delicious and medicinal food. Barn yard millet and Kodo millet are considered as top two millets based on consumer preferences. Millets are considered as good sources for revenue. Millet grain is now receiving more attention from biochemists, nutritionists and patients. If hundred reasons are there for hundred years for a person life period, then, millet may be the one.
