Little millet is one of the small millets known for its nutraceutical properties among other cereals. The shelf life of millet flour can be extended by using various methods, such as use of ionizing radiation and different packaging materials. In the present study, irradiated little millet flour (1.5 kGy) and various packaging materials (LDPE, PP, PET, and MPP) were studied for their storage quality up to three months. The nutritional and functional properties of flour contained 7.7% protein, 6.7% fiber, and 65.43% carbohydrate with high calcium (17.43 mg/100 g) content. Gamma irradiation with PP and LDPE packaging significantly reduced peroxide values over 90 days of storage. The free fatty acid, an indicator of fat deterioration increased significantly for 0–90 days of storage. The alcoholic acidity, determining the age and shelf life of the flour showed increased values in conjunction with moisture content. Overall, irradiated MPP and PET packed samples showed significantly less biochemical changes (moisture, peroxide value, and FFA) without fungal growth. Insect infestation began after 30–45 days of storage in control and non-irradiated PP and LDPE covers, whereas no infestation was observed in MPP and PET packed flour. Thus, gamma irradiation and ideal packaging materials can aid in the preservation of millet flour for up to three months with minimal post-harvest losses. [ABSTRACT FROM AUTHOR] |
