“…Hermetic technologies preserve the percentage of seed germination by limiting oxygen availability and maintaining low-equilibrium relative humidity for stored seed, which in turn slows oxidative reactions associated with decreased seed viability [ 50 ]. These results are valid over an extended storage time (up to 7 months), as demonstrated by Kuyu et al [ 25 ]. Regarding special treatments, percussion treatments in this study tended to reduce the percentage of normal seedlings.…”

“…High oxygen levels are also associated with seed viability declines; mainly due to oxidative processes, particularly in seed stored at high moisture contents [ 21 ]. Storing low moisture content seed using hermetic technologies allows the preservation of seed quality by maintaining a low-equilibrium relative humidity and seed dryness, as well as limiting oxygen availability during storage [ 22 , 23 , 24 , 25 ]. However, there is a lack of evidence on the effect of different storage technologies, as well as the suggested seed treatments, on maize landrace seed germination.…”

Smallholder farmers who grow maize landraces face important challenges to preserve their seed biodiversity from one season to another. This study was carried out in the central highlands of Mexico to compare the effectiveness of two seed storage practices—specifically, polypropylene woven bags (farmers’ conventional practice) vs. hermetic containers—for minimizing seed losses and maintaining germination. Four Mexican landraces were stored for three and six months. Data on moisture content and kernel damage were collected at the beginning and the end of the storage period. Pest-free samples collected were also analyzed for seed germination. Moisture content was below 13% overall and was not significantly affected by storage technology or storage time. Samples from the polypropylene woven bags suffered significant damage from Sitophilus zeamais and Prostephanus truncatus, with the percentages of insect damage and weight loss reaching 61.4% and 23.4%, respectively. Losses were minimal in seed stored in hermetic containers, with a maximum insect damage of 4.1% and weight loss of 2.2%. Overall, the germination rate of samples stored in these airtight containers was greater than 90%. This study provides additional evidence on the effectiveness of hermetic containers at maintaining Mexican landraces’ seed quantity and quality during storage in smallholder conditions in central Mexico.

“…The grains were stored for 7 months at temperature varying from 26.8 to 14.8 °C and relative humidity in the range of 88.4% to 61.8%. Grains stored in hermetic bags had better nutritional properties and seed damage below 3.8% as compared to 61.2% grain damage in jute sacks …”

“…Vacuum decreases the partial pressure of oxygen and water vapor of the interstitial atmosphere resulting the death of insects through dehydration and hypoxia. 47 George et al studied the effectiveness of hermetic bags in storing shea nuts and compared it with jute and polypropylene bags. After 30 weeks of storage period the moisture content variation in hermetic bags was in the range of 1% from initial moisture content as compared to 3% variation in jute and polypropylene bags, insect infestation was around 30% (28% at the beginning of the study) in hermetic bags while in jute and polyprobylene bags it was 82% and 80%, respectively, and the carbon dioxide concentration was below 6% during whole period of study.…”

Millions of people worldwide are deprived of sufficient, safe, and nutritious food required for an everyday and healthy life. The hunger crisis is worsening over time, even though many attempts have been made to minimize it. Increasing world population and competition for natural resources, climate change, natural disasters, urbanization, poverty, and illiteracy are the main causes that need to be addressed to reduce the hunger crisis. Various nonfarm technologies are being used to eradicate hunger but their long-term impact on the environment should also be considered. The real sustainability of several novel technologies being implemented to deal with hunger is an issue to tackle. This paper discusses the potential applications of storage facilities, underutilized crops, waste valorization, food preservation, nutritionally enriched novel food products, and technological advancement in food processing to achieve zero hunger. An attempt has also been made to address the sustainability of various nonfarm technology utilized to minimize the global hunger crisis.

Chickpea (Cicer arietinum L.) is the most important winter season food legumes in Ethiopia. Despite being a major producer and consumer of chickpeas, Ethiopia experiences lower yields due to biotic and abiotic stresses, particularly insect pest infestations during storage. This study aimed to evaluate the impact of different storage technologies and durations on the losses of stored chickpea seeds, both in terms of quantity and quality. The experiment involved five storage technologies and three durations, spanning a period of six months with data collected at two‐month intervals. The results showed that the Purdue Improved Crop Storage (PICS) bag, Super GrainPro (SGP) bags effectively maintained inter‐granular temperature, seed moisture content, and relative humidity throughout the storage period, followed by the modified hermetic metal silo. In contrast, traditional bags exhibited a significant increase in these parameters. The PICS and SGP bags also exhibited the lowest numbers of total insect pests after six months, while the jute bag had the highest infestation. Common insect species found in the stored chickpea seeds were Callosobruchus chinensis (L.), Sitophilus oryzae (L.), and Tribolium confusum (duVal). Furthermore, hermetic bags (PICS and SGP) demonstrated the least grain damage and weight loss, while the jute bags had relatively higher values. Seed viability was well maintained in hermetic bags but significantly decreased in traditional bags. Overall, hermetic storage technologies, such as the PICS and Super GrainPro bags, effectively suppressed insect development, reduced losses, and preserved seed viability without the need for insecticides. It is recommended that farmers use these hermetic storage bags after proper drying to enhance food security and income generation in the country. By implementing these recommendations, Ethiopia can enhance its chickpea storage practices, reduce post‐harvest losses, and contribute to improved food security and economic sustainability in the chickpea sector.This article is protected by copyright.
