The oil extracted from its seeds is a good source of α-linolenic acid, which is an unsaturated fatty acid. Unsaturated fatty acids are prone to oxidation. Pan roasting and hot air oven treatment are crucial pre-treatments for seed oils because they improve extractability, lower moisture content, and preserve oil quality. Therefore, this study investigated the influence of hot air oven treatment and pan roasting on physicochemical and antioxidant characteristics of basil seed oil during nine months of storage. Oil yield of seeds was highest for pan-roasted (PR) sample. The highest DPPH (92.63%) and ABTS (33.34%) scavenging activities were observed for oil derived from oven heated (OD) seeds. Oil derived from pan roasted seeds had the highest density (0.78 g/cm³), peroxide value (36.04 mmol O₂/kg) and carotenoids (2.51 mg/kg). Peroxide (6.01–73.00 mmolO₂/kg), and acid (2.24–6.73 mgKOH/g) values of oils increased significantly (p&lt;0.05) with storage. However, decline in % DPPH inhibition (28.20–92.63%), TFC (9.44–46.20 mgQE/g) and ABTS (5.20–33.34%) contents of oil were observed with storage. Predominance of unsaturated triacylglycerides (TAGs) was observed for fresh oil (FO) due to oxidative degradation of TAGs during hot air treatment and pan roasting. The lowest amount of lipolysis occurred during digestion of FO oil during first 60 min of digestion process. However, during the last 60 min of digestion, the lowest amount of lipolysis was observed for OD sample. Oil from both hot air oven and pan roasted seeds demonstrated superior antioxidant stability over fresh oil, despite deteriorating stability with storage.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"114 ","pages":"Article 102768"},"PeriodicalIF":2.7,"publicationDate":"2025-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144763706","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}

Globally, substantial post-harvest grain losses often exceeding 10–15 % undermine food security, strain supply chains, and waste natural resources, particularly in developing economies such as India. Addressing these losses through technological innovation is essential for achieving sustainable food systems. This review provides a comprehensive analysis of recent technological innovations that are transforming traditional practices in food grain handling. It explores advancements in mechanized cleaning, sensor-based grading, hybrid and renewable energy-assisted drying systems, and precision milling technologies that collectively reduce post-harvest losses and enhance value addition. The paper further examines the integration of smart automation, artificial intelligence (AI), Internet of Things (IoT), and blockchain technologies in storage systems to enable real-time environmental monitoring, predictive maintenance, and traceability throughout the grain supply chain. Emphasis is placed on hermetic storage, controlled and modified atmosphere technologies, and integrated pest management (IPM) approaches that minimize biotic and abiotic deterioration while aligning with food safety standards. Despite significant progress, adoption barriers persist due to high capital costs, inadequate rural infrastructure, limited technical capacity, and fragmented policy support. Emerging trends such as decentralized storage models, community-level processing units, and sustainable packaging solutions are identified as key drivers for inclusive innovation diffusion. The review also outlines future research directions, including climate-resilient infrastructure, low-cost sensor technologies, and AI-augmented post-harvest decision systems. A coordinated policy and institutional ecosystem is deemed essential to facilitate technology penetration at scale, particularly for smallholder and marginal farmers. By synthesizing multidisciplinary insights, this review underscores the transformative potential of technological innovations in building a resilient, efficient, and equitable food grain system that supports long-term agricultural sustainability and food security.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"114 ","pages":"Article 102757"},"PeriodicalIF":2.7,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144738917","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}

This study tested the hypothesis that wheat flour with a history of <em>Tribolium castaneum</em> infestation alters insect preference and development through specific semiochemicals generated or depleted during prior colonization. Significant differences in VOC profiles were detected between uninfested and previously infested flour. Key compounds such as sucrose, ethyl linoleate, phthalic acid ester, and N-(2-hydroxyethyl) decanamide appeared exclusively in uninfested flour, while hexadecenoic acid, linoelaidic acid, and 11-methylpentacosane were unique to beetle-infested flour. Biological assays revealed that uninfested flour supported greater consumption, food conversion efficiency, insect growth, reproduction, and flour loss compared to infested flour. However, no significant difference in initial insect preference between the two substrates was observed. Results suggest that certain VOCs found in uninfested flour may reduce initial attraction but promote consumption, whereas VOCs unique to infested flour enhance colonization preference but suppress feeding. Importantly, substrate preference alone does not predict consumption, which is the key driver of insect development, progeny production, and wheat flour degradation. These findings deepen our understanding of flour beetle-chemical interactions and provide a foundation for targeted pest control strategies based on VOC manipulation.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"114 ","pages":"Article 102766"},"PeriodicalIF":2.7,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144723515","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}

This study addresses this gap by investigating the effects of chitosan, CO₂, and MAP on the shelf life and quality of fully ripened ‘Irwin’ mangoes stored under two storage conditions: room temperature (20 °C) for 12 days, and cold storage (7 °C) for 14 days followed by 9 days at ambient temperature to simulate commercial market conditions. The treatments included 1 % chitosan, 10 % CO₂ for 2 h, and 150,000 cc MAP. The physicochemical characteristics, respiratory gases, ethylene content, and disease incidence were then measured. Among the treatments, MAP was the most effective in preserving fruit quality. It significantly reduced weight loss to 0.7 % at room temperature and 0.8 % after cold storage, compared to 11.4 % and 9.5 % in untreated fruits, respectively. Firmness was better retained in MAP-treated mangoes (4.2 N) than in controls. Additionally, MAP-treated fruits showed the lowest incidence of anthracnose lesions (&lt;1 %) and maintained acceptable external appearance throughout storage. Chitosan treatment moderately reduced disease severity but caused surface wrinkling, while CO₂ treatment had a limited impact. Overall, MAP was the most effective treatment, extending total shelf-life to 20 days while preserving physicochemical and visual quality. These results demonstrate the practical value of MAP as a scalable postharvest strategy for reducing losses and enhancing the marketability of ‘Irwin’ mangoes.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"114 ","pages":"Article 102762"},"PeriodicalIF":2.7,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144723514","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}

Aggregation pheromones, mediating intraspecific communication, foraging, and reproduction among Bostrichidae species, and have been increasingly exploited for the development of pheromone-based lures to monitor and manage their populations in both indoor storages and fields. This review highlights current knowledge on aggregation pheromones from four previously reported bostrichid species, i.e., <em>Rhyzopertha dominica</em> (Fabricius), <em>Prostephanus truncatus</em> (Horn), <em>Dinoderus bifoveolatus</em> (Wollaston), and <em>Lyctus africanus</em> Lesne.

Additionally, we summarize the chemical synthesis procedures of these pheromones, and assess the efficacy of different trap designs, lure formulations, placements, and heights. Finally, we discuss the limitations in species coverage of current studies, practical application, and the understanding of olfactory mechanisms of aggregation pheromones. By consolidating fragmented knowledge and identifying research gaps, this review provides a scientific foundation for improving monitoring and control strategies.
