“…Other farmers also sell their surplus crop harvests for fear of losing them to the agents of deterioration during storage [22] [46]. When sold immediately after harvest, households will be forced, in a few months, to buy grains at relatively higher prices than sold to meet their food needs [12] [47] [48]. Among other factors, this has kept many smallholder farmers of SSA in perpetual poverty.…”

“…Insect pests are the greatest challenge to stored grains, causing significant quantity and quality loss of up to 40% in some commodities [52]. By using HSTs, insect pests cannot thrive due to the creation of interstitial modified atmospheres of low oxygen and high carbon dioxide [48] [53] [54]. Due to inadequate oxygen supply, cessation of insect feeding, growth, development, reproduction, and eventual death occurs for insect pest species and their life stages [55].…”

Post-harvest storage losses (PHLs) remain significant in Sub-Saharan Africa (SSA) due to several factors mainly insect pests and molds. Hermetic storage technologies (HSTs) are being promoted to address these storage losses. In Uganda, HSTs were first introduced in 2012. However, its use among farming households remains low today. Data were collected from 306 smallholder farmers from four districts of Northern Uganda using a pre-tested semistructured questionnaire to understand their knowledge, use, and constraints to the adoption of hermetic storage. A multivariate Logit regression model was used to find the significance of the factors affecting adoption. Results showed low awareness and use of hermetic storage among smallholder farmers. Only 53.3% of the interviewed farmers were aware of the use of hermetic storage for grain storage. The SuperGrain bag was the most known form of hermetic storage (35.3%), followed by the Purdue Improved Crop Storage (PICS) bag (34.9%), metallic silo (15.5%), and plastic silo (14.4%). Hermetic storage use was even lower as only 17.6% of the surveyed farmers were using one or more forms of hermetic storage to store their grains. Insect pest management without chemical insecticides was the main reason (83.1%) for hermetic storage use. About 75.5% of those aware of hermetic storage had received training in the technology. Hermetic storage use in farming households led to improved food availability, household income, and nutrition. Lack of local availability (50.2%), high costs (37.8%), and inadequate knowledge (6.

“…The production of AFs by toxigenic Aspergillus species is influenced by various factors, including water activity (aw), temperature, substrate concentration, pH, and incubation time ( Northolt and Bullerman, 1982 , Omara et al, 2020 ). AF contamination in crops, particularly in legumes, cereals, nuts, and oil seeds, poses significant risks to human and animal health, as well as trade, due to the carcinogenic properties of AFB1 and its association with hepatocellular carcinoma ( Okori et al, 2022 ).…”

“…In a recent comprehensive review on grain hermetic storage and postharvest loss reduction in Sub‐Saharan Africa, it was concluded that hermetic storage technologies, such as layered bags and grain silos, effectively prevent losses and maintain grain quality, resulting in enhanced prices, safety, and nutrition for consumers. However, the review lacked quantitative comparisons between conventional and hermetic storage methods due to the absence of data meta‐analysis 29 …”

“…However, the review lacked quantitative comparisons between conventional and hermetic storage methods due to the absence of data meta-analysis. 29 This paper synthesizes data from multiple independent studies in which grain quality was evaluated following storage in hermetic and conventional bags. We focused on grain crops commonly cultivated by smallholder farmers in Sub-Saharan Africa.…”

Postharvest management is critical to attaining household food, nutrition, and income security. Hermetic grain storage bags offer an effective pesticide‐free way to protect stored grain against fungal and insect infestation. We evaluated articles indexed in the Web of Science that included experiments comparing the storage efficacy of conventional and hermetic storage bags based on grain germination rate, insect infestation, physical damage, mycotoxin contamination, and changes in weight and moisture content. Compared with grain stored in hermetic bags, grain stored in conventional bags lost 3.6‐fold more seed viability, contained 42‐fold more insects, had 11‐fold more physical damage, and lost 23‐fold more grain weight, while grain moisture levels were similar for both hermetic and conventional storage bags. Mycotoxin contamination levels were not as frequently assessed. Levels could be low in grain stored in both types of bags, or levels could be low in hermetic bags and significantly higher in conventional bags. The improved properties of grain stored in hermetic bags can increase food security and household income by providing safe storage options for maintaining seed germinability, and for consumption and/or sale when food supplies are high, or when prices are low. Hermetic bags are economically feasible for use by subsistence farmers in Sub‐Saharan Africa for grain for household consumption and for carrying‐over seed for planting in the next season. Additional studies are needed to verify the mycotoxin contamination results and to determine if there are differences in functional food characteristics, e.g. flavor and cooking properties, that have not been as comprehensively studied. © 2023 The Authors.
