This review highlights the key constituents of EOs, including terpenes, aldehydes, alcohols, ketones, and alkaloids, and evaluates their effectiveness against grain storage pests and microorganisms. We discuss various extraction methods, highlighting their advantages and disadvantages. EOs are shown to act through fumigation, contact, and behavioral disruption, although their precise mechanisms of action require further study. Their applications extend to pest eradication, mold prevention, and weed control, enhancing the effectiveness of pesticides. The role of microencapsulation and nanotechnology in stabilizing EOs for broader use in grain preservation is also explored, emphasizing their potential to enhance stored grain safety. Balancing the discussion on essential oils' utility, this review emphasizes the necessity for continuous research and innovation in sustainable pest management strategies.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"111 ","pages":"Article 102537"},"PeriodicalIF":2.7,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143180510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using proximate composition analysis as per the Association of Official Analytical Chemists (AACC) standards, the results showed that after six months of storage, PICS bags preserved the highest germination energy (87.83%), whereas underground pits had the lowest (39.79%). PICS bags were the only technology maintaining germination viability above 85%. Moisture content increased across all storage technologies, with the most significant rise observed in underground pits (11.42%–17.48%). Nutrient losses, including reductions in protein, fiber, ash, and fat, were more pronounced in grains stored in filter-cake-treated bags, ZeroFly bags, polypropylene bags, and underground pits. However, minimum loss was recorded in the PICS bag. Sensory analysis demonstrated that injera made from sorghum stored in PICS bags received the highest preference scores. The findings highlight that PICS bags effectively preserve the physical, nutritional, and sensory quality of sorghum grains while mitigating storage losses. Consequently, PICS bags are recommended as a sustainable and eco-friendly solution for improving postharvest grain management in diverse agro-ecological settings in Tigray, Ethiopia.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"111 ","pages":"Article 102530"},"PeriodicalIF":2.7,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143105054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
