The findings indicated that hermetic storage facilities outperformed conventional ones throughout the six-month storage period. For instance, GrainPro PHB exhibited the minimal increase in grain moisture contents (0.50 and 0.33%), resulting in the least grain damage (2.38 and 2.44%) and weight loss (0.93 and 0.39%) during both years, respectively. Additionally, GrainPro PHB recorded the highest seed germination (90.50 and 90.33%) for both years. Compared to conventional storage methods, GrainPro PHB exhibited a lower number of storage insects. The proximate composition analysis revealed significant nutritional differences between polypropylene bags and GrainPro PHB. GrainPro PHB successfully maintained proximate composition, with minimal decreases in protein (1.03 and 0.71%), fat (16.88 and 14.95%), and starch content (0.8 and 0.5%) and minimal increases in ash (25.00 and 23.33%) and fiber contents (18.33 and 16.80%) in both years. Moreover, results revealed a positive correlation between grain moisture contents and damage parameters, suggesting that the higher moisture contents may aggravate the percent grain damage and weight loss. There were also better rheological properties in flour made from grains stored in GrainPro PHB, like a lower minimum water absorption capacity (WAC), a longer dough development time (DDT), and a maximum dough stability time (DST). Furthermore, texture profile analysis (TPA) of bread made from flour stored in GrainPro PHB showed improved texture, with higher chewiness, cohesiveness, springiness, and resilience, and lower hardness, resulting in superior overall quality compared to bread made from conventionally stored grains. Eventually, these findings underscore the effectiveness of hermetic storage facilities in maintaining grain moisture contents, reducing losses, preserving seed quality, and enhancing food and nutrition security.
