Effectiveness of Hermetic Bag for Long-Term Storage of Pearl Millet Grains

Abstract

The study aimed to evaluate the effectiveness of hermetic bags for long-term storage of pearl millet grains. The experiment was conducted with moisture levels of 10%, 12%, and 14% (wb). Grains stored in hermetic bags showed a smaller range of temperature fluctuations. In samples with higher moisture levels, the decrease in oxygen concentration and the increase in carbon dioxide concentration were more evident. The findings also indicate that the moisture content of the grains was maintained by the hermetic bags with minimal variation. In comparison to the polypropylene bags, the germination percentage of pearl millet grains stored in hermetic bags was higher. During the storage period, the brightness value of pearl millet samples experienced a significant decrease, resulting in a darker appearance. Despite no noticeable variation in the milling characteristics of pearl millet grains during storage, these characteristics were significantly influenced by the grain moisture content at the time of milling. Hence, hermetic bags can be considered as a viable option for the long-term storage of pearl millet grains.
