Microwave vacuum drying, due to the high efficiency of dielectric heating and vacuum's temperature-friendly conditions, has gained increasing attention. This study examined the moisture migration behavior of Camellia oleifera seeds during microwave vacuum drying and its effects on oil release and product quality. Results showed pronounced moisture variation, with the drying rate rising initially and then declining. The effective moisture diffusion coefficient was 1.358 × 10⁻⁸ m²/s, and the Page model accurately described the drying kinetics. Oil content first increased, peaking at 15 min with a 43.06 % rise over the initial value, before declining with prolonged drying. Bound and immobile water decreased steadily. Structural deformation of the seed shell and kernel intensified with drying time and moisture loss, leading to a denser pore distribution per unit area, along with visible oil exudation on the seed surface. X-ray micro-CT analysis confirmed outward moisture migration from the interior, beginning with small core pores that enlarged and merged over time. Total and open porosity increased continuously, while closed porosity rose to 5.67 ± 0.27 % at 10 min before declining. Correlation analysis emphasized the dominant role of moisture variation in pore formation. Overall, these findings provide new insights into the drying behavior of Camellia oleifera seeds under microwave vacuum conditions.

微波真空干燥由于介质加热效率高和真空的温度友好性而受到越来越多的关注。研究了微波真空干燥过程中油茶种子的水分迁移特性及其对油茶种子油脂释放和产品品质的影响。结果表明，水分变化明显，干燥速率先上升后下降。有效水分扩散系数为1.358 × 10−8 m2/s， Page模型准确地描述了干燥动力学。含油量首先增加，在15 min时达到峰值，比初始值增加43.06%，然后随着干燥时间的延长而下降。束缚和不流动的水稳步减少。随着干燥时间的延长和水分的流失，种子壳和籽粒的结构变形加剧，导致单位面积孔隙分布更密集，种子表面有明显的油脂渗出。x射线微ct分析证实了水分从内部向外迁移，开始于随着时间的推移而扩大和合并的小岩心孔隙。总孔隙度和开放孔隙度持续增加，封闭孔隙度在10 min时上升至5.67±0.27%，随后下降。相关分析强调水分变化对孔隙形成的主导作用。综上所述，这些发现为研究油茶种子在微波真空条件下的干燥行为提供了新的思路。

Fresh table grapes are highly perishable and prone to rachis browning, berry shattering, shriveling, and overall quality loss, thereby limiting their storage life and accelerating quality deterioration. In this study, table grapes were coated with oligochitosan (OGC) at concentrations of 0, 0.25 %, 0.5 %, and 1 %, and stored under ambient storage conditions (ASC, 20 °C) and low-temperature storage (LTS, 4 °C) for 15 and 30 days (d), respectively. It was found that the 1 % OGC treatment was most effective among all the applied coating concentrations at both temperatures. The 1 % OGC treatment reduced weight loss, decay incidence, and berry shattering. The OGC treatment reduced malondialdehyde, electrolyte leakage, hydrogen peroxide, and superoxide anion, indicating suppressed oxidative stress along with reduced respiration and ethylene production. It also stimulated the activities of glutamate decarboxylase (GAD) and γ-aminobutyric acid aminotransferase (GABA-T), resulting in higher GABA content. Antioxidant enzymes and non-enzymatic antioxidants-including ascorbic acid, glutathione, phenols, and flavonoids-were also elevated in treated grapes. The OGC-coated grapes retained higher titratable acidity and exhibited lower soluble solids content. In addition, the 1 % OGC treatment extended the shelf life (based on sensory quality limit) of table grapes by 10 d under LTS and by 6 d at ASC conditions. Therefore, the OGC (1 %) could be considered an ecofriendly coating for preserving the postharvest quality of table grapes under LTS and at ASC conditions.

新鲜鲜食葡萄极易腐烂，容易发生果轴褐变、浆果碎裂、枯萎和整体品质损失，从而限制了它们的储存寿命，加速了品质的恶化。在本研究中，鲜食葡萄分别涂上浓度为0、0.25%、0.5%和1%的低聚壳聚糖（OGC），在常温（ASC, 20°C）和低温（LTS, 4°C）条件下分别保存15天和30天。结果表明，在两种温度下，1% OGC处理效果最好。1%的OGC治疗减少了体重下降、腐烂发生率和浆果碎裂。OGC处理减少了丙二醛、电解质泄漏、过氧化氢和超氧阴离子，表明氧化应激受到抑制，呼吸和乙烯产量减少。刺激谷氨酸脱羧酶（GAD）和γ-氨基丁酸转氨酶（GABA- t）活性，使GABA含量升高。抗氧化酶和非酶抗氧化剂——包括抗坏血酸、谷胱甘肽、酚类和类黄酮——在处理过的葡萄中也有所升高。ogc包覆后的葡萄可滴定酸度较高，可溶性固形物含量较低。此外，1% OGC处理延长了鲜食葡萄的保质期（基于感官质量限制），在LTS条件下延长了10天，在ASC条件下延长了6天。因此，OGC（1%）可以被认为是一种在LTS和ASC条件下保持鲜食葡萄采后品质的环保涂层。

Nanotechnology offers innovative solutions for enhancing agricultural sustainability, with zinc oxide nanoparticles (ZnO-NPs) emerging as particularly promising agents for improving crop resilience and pest management. However, their potential specifically against Phthorimaea operculella a devastating pest causing significant pre- and post-harvest losses in potato cultivation remains underexplored. This study investigates the efficacy of Sargassum ilicifolium-synthesized ZnO-NPs as a dual-function agent to improve potato tuber quality and manage the destructive pest P. operculella. Tubers treated with 50 and 100 ppm exhibited significantly enhanced quality, with peak hardness (90.10 and 89.56 %) and elevated levels of total phenolics (282.6 and 271.5 mg GAE/g). The 50 ppm treatment yielded the highest flavonoid content and antioxidant activity (93.06 mg QE/g and 91.73 %), significantly exceeding control values (84.61 mg QE/g and 43.48 %, respectively). The most pronounced effects were observed at 100 ppm, which extended egg development duration to 7.55 days, reduced female fecundity to 34.18 eggs, and suppressed the intrinsic rate of increase (r) to 0.067 day⁻¹, compared to control values of 3.47 days, 146.7 eggs, and 0.128 day⁻¹, respectively. Furthermore, the 100 ppm induced severe morphological deformities in 51.4 % of emerging adults, predominantly manifesting as crumpled wings and eclosion failure. Our study confirms the dual efficacy of bio-synthesized ZnO-NPs (50–100 ppm) in potato cultivation, where they simultaneously function as a tuber quality enhancer and a potent bio-fertilizer against moth. This nanotechnology provides a sustainable IPM solution that enhances post-harvest quality and controls pests, effectively reducing economic losses while minimizing environmental impact through decreased pesticide reliance.

纳米技术为提高农业可持续性提供了创新的解决方案，氧化锌纳米颗粒（ZnO-NPs）正在成为提高作物抗逆性和病虫害管理的特别有前途的药剂。然而，它们对马铃薯种植中造成重大收获前和收获后损失的一种破坏性害虫——薄皮霉（Phthorimaea operculella）的特异性潜力仍未得到充分探索。研究了马尾藻合成ZnO-NPs对马铃薯块茎品质的双重防治效果。50和100 ppm处理的块茎质量显著提高，硬度峰值分别为90.10和89.56%，总酚含量分别为282.6和271.5 mg GAE/g。50 ppm处理的黄酮类化合物含量和抗氧化活性最高，分别为93.06 mg QE/g和91.73%，显著高于对照（84.61 mg QE/g和43.48%）。在100 ppm浓度下，虫卵发育时间延长至7.55天，雌虫产卵量减少至34.18个卵，内在增长率(r)抑制至0.067天−1，而对照值分别为3.47天、146.7个卵和0.128天−1。此外，100 ppm会导致51.4%的新生成虫出现严重的形态畸形，主要表现为翅膀皱褶和羽化失败。本研究证实了生物合成ZnO-NPs （50-100 ppm）在马铃薯栽培中的双重功效，在马铃薯栽培中，它们同时具有块茎品质增强剂和抗蛾生物肥料的作用。这种纳米技术提供了一种可持续的IPM解决方案，可以提高收获后的质量并控制害虫，有效地减少经济损失，同时通过减少对农药的依赖，最大限度地减少对环境的影响。

Plant-derived foods are essential components of the human diet, and their postharvest quality profoundly affects market value, storage stability, and consumer acceptance. Conventional quality evaluation methods relying on manual inspection are often time-consuming, subjective, and inconsistent, creating an urgent need for intelligent, automated alternatives. This review provides a comprehensive synthesis of recent advances in artificial intelligence (AI) and machine learning (ML) for non-destructive fruit quality assessment. Emphasis is placed on imaging-based technologies including RGB, multispectral, hyperspectral, X-ray, and magnetic resonance imaging that enable precise extraction of external and internal quality attributes such as color, texture, geometry, and biochemical composition. The integration of AI with complementary sensing systems, such as electronic noses and tongues, Internet of Things networks, and robotic platforms, is also discussed for achieving real-time sorting, grading, and early disorder detection. Key insights reveal the growing efficacy and versatility of AI-driven solutions in enhancing precision, speed, and sustainability of postharvest management. Nevertheless, challenges remain regarding dataset standardization, model interpretability, and cross-commodity generalization. Future research should focus on explainable AI, multimodal data fusion, and large-scale validation under practical conditions. Collectively, AI-enabled technologies are redefining postharvest fruit quality management toward a more intelligent and sustainable future.

植物性食品是人类饮食的重要组成部分，其采后质量对市场价值、储存稳定性和消费者接受程度有着深远的影响。依靠人工检查的传统质量评估方法通常是耗时的、主观的和不一致的，因此迫切需要智能的、自动化的替代方法。本文综述了人工智能（AI）和机器学习（ML）在无损水果质量评估方面的最新进展。重点放在基于成像的技术上，包括RGB、多光谱、高光谱、x射线和磁共振成像，这些技术能够精确提取外部和内部质量属性，如颜色、纹理、几何形状和生化成分。还讨论了人工智能与互补传感系统（如电子鼻和电子舌）、物联网网络和机器人平台的集成，以实现实时分拣、分级和早期疾病检测。关键见解揭示了人工智能驱动的解决方案在提高采收后管理的精度、速度和可持续性方面的有效性和多功能性。然而，在数据集标准化、模型可解释性和跨商品泛化方面仍然存在挑战。未来的研究应侧重于可解释的人工智能、多模态数据融合和实际条件下的大规模验证。总的来说，人工智能技术正在重新定义采后水果质量管理，朝着更加智能和可持续的未来发展。

Sustainable low-residue interventions are urgently needed against quarantine pests of stored commodities. Thus, this study evaluated clove (Syzygium aromaticum) and marjoram (Origanum majorana) essential oils applied at 0.10–1.00 % (w/v) to three carriers (activated charcoal, cork granules, filter paper) and tested fourth-instar larvae and 7–10-day adults of Trogoderma granarium for repellency, feeding deterrence, acute mortality (24, 48, 72 h), substrate weight loss and seed germination. Repellency was life-stage dependent: adults were markedly more repelled than larvae while concentration explained negligible variance (R² ≤ 0.09; all p > 0.05; marginal trend for adults on charcoal p = 0.060). Feeding deterrence exhibited strong log-dose responses across oils and carriers (OLS R² = 0.59–0.88; F_1,48 = 25.5–129.2; P ≤ 1.2 × 10⁻⁹), with clove producing consistently steeper slopes than marjoram. Adult and larval mortality increased with dose and exposure time; at 1.0 % clove adult mortality reached 58.1 %, 84.3 % and 92.9 % at 24, 48 and 72 h, respectively, and larval 72 h fits attained R² up to 0.96 (P ≤ 9.45 × 10⁻¹⁴). Carrier choice modulated commodity impacts and germination (quadratic fits R² ≈ 0.93–0.98). Canonical multivariate analysis identified a dominant discriminant (first canonical correlation r = 0.88; P < 0.001) linking life stage, residual mortality, feeding inhibition and weight loss. Clove on sorptive carriers (charcoal, cork) provided superior and sustained protection, supporting prioritised formulation development and targeted field validation for low-residue stored-product protection.

目前迫切需要可持续的低残留干预措施来防治储存商品的检疫性有害生物。因此，本研究评估了丁香（Syzygium aromaticum）和马郁兰（Origanum majorana）精油以0.10-1.00 % （w/v）的剂量涂抹在三种载体（活性炭、软木颗粒、滤纸）上，并测试了谷物Trogoderma granarium 4龄幼虫和7 - 10天成虫的驱避、阻食、急性死亡率（24、48、72 h）、基质失重和种子萌发。驱避是生活期依赖性的，成虫的驱避能力明显强于幼虫，而浓度对方差的解释可以忽略不计（R2≤0.09；均p >； 0.05；木炭上成虫的边际趋势p = 0.060）。在不同的油脂和载体中，摄食威慑表现出强烈的对数剂量反应（OLS R2 = 0.59-0.88; F1,48 = 25.5-129.2; P≤1.2 × 10 - 9），丁香产生的斜坡始终比马郁兰更陡峭。成虫和幼虫的死亡率随剂量和暴露时间的增加而增加；1.0%时，24、48和72 h成虫死亡率分别为58.1%、84.3%和92.9%，72 h幼虫死亡率R2达0.96 （P≤9.45 × 10−14）。载体选择调节商品影响和发芽（二次拟合R2≈0.93-0.98）。典型多变量分析发现了一个显性判别（第一典型相关r = 0.88; P < 0.001），将生命阶段、剩余死亡率、摄食抑制和体重减轻联系起来。吸附载体（木炭，软木）上的丁香提供了卓越和持续的保护，支持优先配方开发和低残留存储产品保护的目标现场验证。

Host switching, a strategy for population rejuvenation, is essential for sustaining pest control efficacy of parasitic natural enemies. This study evaluated the effects of switching the host of Habrobracon hebetor, reared long-term on Ephestia elutella, to either Plodia interpunctella or Corcyra cephalonica for five consecutive generations. The assessment focused on the parasitoid's subsequent parasitism fitness toward the original host, E. elutella, as well as the across parental and first offspring generations effects. Results showed that host switching significantly increased the number of hosts paralyzed, number of hosts parasitized, and fecundity of the parental generation of H. hebetor on E. elutella. The P. interpunctella–switched group achieved the highest number of parasitized hosts and fecundity, along with significantly extended female longevity. Offspring experiments revealed a shorter larval developmental period in the P. interpunctella–switched population with high percentages of pupal formation and adult emergence. Offspring from this group also showed significantly superior paralysis, parasitism, and fecundity relative to the control and C. cephalonica–switched groups, indicating that fitness benefits from host-switching persist across generations. Overall, P. interpunctella emerged as an optimal alternate host for rejuvenating H. hebetor populations, enhancing parasitic performance and longevity, likely through nutritional or physiological mechanisms. This study provides theoretical and practical guidance for rejuvenating H. hebetor in mass rearing under laboratory conditions, with application value for improving biological control efficacy.

寄主转换是一种种群复兴策略，是维持寄生性天敌害虫防治效果的必要手段。本研究评估了长期饲养在埃弗斯提亚（Ephestia elutella）上的哈伯角龙（habrobrabon hebetor）连续五代转换为间点倍亚（Plodia interpunctella）或头尾草（Corcyra cephalonica）的效果。评估的重点是寄生蜂对原始寄主elutella的后续寄生适合度，以及跨亲代和第一代后代的效应。结果表明，寄主转换显著增加了褐家蝇的麻痹寄主数、被寄生寄主数和亲本代对褐家蝇的繁殖力。点间假单胞虫切换组的被寄生寄主数量和繁殖力最高，雌性寿命显著延长。子代实验结果表明，换虫种群的幼虫发育周期较短，蛹形成率和成虫羽化率较高。这一组的后代在麻痹性、寄生性和繁殖力方面也明显优于对照组和调换了宿主的组，这表明调换宿主带来的健康益处在几代之间持续存在。总体而言，点间假单胞虫可能通过营养或生理机制，成为使大黄蜂种群恢复活力的最佳替代寄主，从而提高寄生性能和寿命。本研究为在实验室条件下进行大鼠回春养殖提供了理论和实践指导，对提高生物防治效果具有应用价值。

Hermetic storage bags (HSBs) are being introduced to smallholder farmers in sub-Saharan African countries to help mitigate postharvest grain losses. For widespread adoption of storage technologies to occur, they need to be acceptable, effective and economical. This study examined the economic impact of using different grain storage practices among smallholder farmers in selected districts of Zimbabwe. A partial budget analysis was employed to estimate the economic costs and benefits of storage practices and to compute the Marginal Rate of Return (MRR) between alternative storage practices. The results indicated that for maize and cowpeas, the MRR of changing from storing untreated grain in polypropylene bags to using HSBs was 544 % and 3059 %, respectively; assuming a 3-season lifespan of HSBs. If HSBs only last a single season's use, they are not economically viable for maize, but when used for two seasons, they yield a marginally acceptable return (MRR = 115 %). For cowpeas, even if the lifespan is limited to one or two seasons, use of HSBs remain economically viable, yielding MRRs of 252 % and 955 %, respectively. This highlights the need for proper handling, hygiene and maintenance of HSBs to ensure durability and maximise economic benefits. For maize, synthetic chemical grain protectant pesticide had a higher cost and lower net benefit than HSBs, so was considered a dominated treatment, indicating HSB use would be preferable. Economically, HSBs offer the best return on investment, helping smallholder farmers reduce losses and pesticide use, in addition to enhancing food, income, and nutrition security.

撒哈拉以南非洲国家正在向小农推广密封贮藏袋（hsb），以帮助减轻收获后的粮食损失。为了广泛采用存储技术，它们必须是可接受的、有效的和经济的。本研究调查了在津巴布韦选定地区的小农中使用不同粮食储存方法的经济影响。采用部分预算分析方法估算了不同存储方式的经济成本和效益，并计算了不同存储方式之间的边际收益率。结果表明，对玉米和豇豆而言，聚丙烯袋装与HSBs的MRR分别为544%和3059%；假设hsb的寿命为3个季节。如果hsb只持续一个季节的使用，它们对玉米来说在经济上是不可行的，但如果使用两个季节，它们产生的回报是可以接受的（MRR = 115%）。对于豇豆来说，即使寿命限制在一到两个季节，使用hsb在经济上仍然是可行的，mrr分别为252%和955%。这突出了对hsb的正确处理、卫生和维护的需要，以确保耐久性和最大限度地提高经济效益。对玉米而言，合成化学谷物保护剂农药的成本较高，净效益较HSB低，因此被认为是一种优势处理，表明使用HSB是可取的。从经济上讲，hsb提供了最佳的投资回报，除了提高粮食、收入和营养安全外，还帮助小农减少损失和农药使用。

Contact insecticides are one of the most used control and prevention methods for managing stored product insects however, the efficacy of organic or natural insecticides across multiple surfaces is limited. The objective of this study was to evaluate a deltamethrin, pyrethrin, and spinosad insecticide formulations applied to metal and concrete surfaces to control adults of six species of stored product insects. Metal and concrete arenas were treated with an insecticide, and ten adults of each species, including Tribolium castaneum (Herbst), Rhyzopertha dominica (F.), Cryptolestes ferrugineus (Stephens), Tribolium confusum Jacquelin du Val, Sitophilus zeamais Motschulsky, or Oryzaephilus surinamensis (L.), were added to treated arenas and evaluated for survival at 1, 3, or 7 days after exposure. Insect survival was significantly lower on metal (nonabsorbent) compared to concrete surfaces (absorbent). Among all species, insect survival was <5 % on metal surfaces treated at the high label rate of pyrethrin. Tribolium castaneum and T. confusum were the two most tolerant species. Tribolium spp. survival ranged from 40 to 100 % on metal and concrete arenas treated with deltamethrin and spinosad. Overall, all the insecticides were more effective on metal surfaces. Results of this study demonstrate the broad-spectrum efficacy of three different formulations of contact insecticides, however their efficacy depends on the surface substrate. Thus it is imperative that the species and surface properties be considered before application of a contact insecticide to provide a more targeted application treatment in processing facilities, storage areas, or as a pre-bin treatment.

接触式杀虫剂是储藏产品昆虫最常用的控制和预防方法之一，然而，有机或天然杀虫剂在多个表面的效果有限。本研究的目的是评价溴氰菊酯、除虫菊酯和spinosad杀虫剂配方对金属和混凝土表面6种储存品昆虫成虫的控制效果。用杀虫剂处理金属和混凝土竞技场，并在处理后的竞技场中分别添加10只成虫，包括castaneum （Herbst）、Rhyzopertha dominica （F.）、Cryptolestes ferrugineus （Stephens）、Tribolium confusum Jacquelin du Val、Sitophilus zeamais Motschulsky和Oryzaephilus surinamensis (L.)，并在暴露后1、3和7天评估其存活率。与混凝土表面（吸收剂）相比，金属表面（非吸收剂）的昆虫存活率明显较低。在高标记率除虫菊酯处理的金属表面上，昆虫的存活率为5%。castaneum和T. confusum是两个最具耐受性的物种。在溴氰菊酯和spinosad处理的金属和混凝土舞台上，Tribolium的存活率为40%至100%。总体而言，所有杀虫剂对金属表面更有效。本研究结果表明，三种不同配方的接触性杀虫剂具有广谱药效，但其药效取决于表面基质。因此，必须在施用接触杀虫剂之前考虑其种类和表面性质，以便在加工设施、储存区域或作为预仓处理提供更有针对性的施用处理。

Insect pests significantly degrade the physical and chemical quality of stored agricultural commodities, including nuts. This study investigated the impact of the Indian meal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae), infestations on the quality of hazelnuts from four premium cultivars of Türkiye: ‘Çakıldak’, ‘Mincane’, ‘Palaz’, and ‘Tombul’. Raw hazelnuts were infested with P. interpunctella larvae under controlled laboratory conditions. Quality parameters, including proximate composition, fatty acid profile, amino acid composition, and oxidative stability, were analyzed. The results revealed significant reductions in antioxidant activity (DPPH-RSA, TPC) and increases in free fatty acid (FFA) levels and peroxide values (PV) across all hazelnut cultivars. Çakıldak cultivar exhibited the greatest lipid degradation among them. Protein content and tocopherol levels varied across cultivar, indicating a differential susceptibility to infestation. An increase in saturated fatty acids and a change in the ratio of PUFA/SFA were observed in the fatty acid profile. Additionally, feeding the moth with hazelnuts led to a rise in free fatty acids (FFAs) due to hydrolytic and enzymatic degradation, an increase in lipid oxidation and in free amino acid (FAA) levels resulting from protein degradation. These processes significantly altered the chemical composition and nutritional quality of the hazelnuts.

害虫会显著降低储存农产品（包括坚果）的物理和化学质量。本文研究了印度斑间倍蛾（Plodia interpunctella (h bner)）（鳞翅目：皮蛾科）侵染对4个优质榛果品种（‘ Çakıldak ’、‘ Mincane ’、‘ Palaz ’和‘ Tombul ’）榛子品质的影响。在实验室控制条件下，对生榛子进行了点间假单胞虫幼虫侵染。分析了质量参数，包括近似组成、脂肪酸谱、氨基酸组成和氧化稳定性。结果显示，所有榛子品种的抗氧化活性（DPPH-RSA， TPC）显著降低，游离脂肪酸（FFA）水平和过氧化值（PV）增加。其中Çakıldak品种脂质降解程度最大。蛋白质含量和生育酚水平在不同品种之间存在差异，表明对侵染的不同敏感性。在脂肪酸谱中观察到饱和脂肪酸的增加和PUFA/SFA比值的变化。此外，用榛子喂养飞蛾会导致水解和酶降解导致的游离脂肪酸（FFAs）增加，脂质氧化和蛋白质降解导致的游离氨基酸（FAA）水平增加。这些过程显著地改变了榛子的化学成分和营养品质。

Soybean (Glycine max) is widely regarded as one of the most important oilseeds crops worldwide, valued for its critical source of protein, oil, and feed. However, its high lipid content and sensitivity to environmental factors make soybean particularly vulnerable to post-harvest losses during storage and preservation. This review synthesizes current knowledge on soybean storage systems, encompassing pre-harvest and harvest practices, drying methods, and both traditional (bag, bin) and modern (silo, hermetic, modified atmosphere, refrigeration) storage approaches. It critically evaluates chemical, biological, and physical seed preservation methods, alongside eco-friendly alternatives such as bio-priming and seed pelleting. Special attention is given to key quality determinants including seed moisture, viability, respiration, packaging, and genotype-dependent responses. Comparative insights from major soybean economies Brazil, United States, Argentina, China, and India highlight how storage infrastructure, policy, and environmental conditions influence preservation outcomes. The review further explores limitations in current storage strategies, such as lipid oxidation, microbial infestation, and inadequate farmer-level facilities, and identifies emerging opportunities in nanotechnology, smart packaging, and climate-resilient preservation systems. Future research must integrate sustainable storage technologies with real-time quality monitoring to minimize post-harvest losses, extend shelf life, and ensure soybean's contribution to global food and nutritional security.

大豆（Glycine max）被广泛认为是世界上最重要的油籽作物之一，因其蛋白质、油脂和饲料的重要来源而受到重视。然而，大豆的高脂含量和对环境因素的敏感性使其在储存和保存过程中特别容易遭受收获后的损失。这篇综述综合了目前关于大豆储存系统的知识，包括收获前和收获实践，干燥方法，以及传统（袋，仓）和现代（筒仓，密封，修饰气氛，冷藏）储存方法。它严格评估化学，生物和物理种子保存方法，以及生态友好的替代品，如生物启动和种子颗粒。特别关注关键的质量决定因素，包括种子水分、活力、呼吸、包装和基因型依赖性反应。来自巴西、美国、阿根廷、中国和印度等主要大豆经济体的比较观点强调了储存基础设施、政策和环境条件如何影响保存结果。这篇综述进一步探讨了当前储存策略的局限性，如脂质氧化、微生物感染和农民水平设施不足，并确定了纳米技术、智能包装和气候适应性保存系统的新兴机会。未来的研究必须将可持续储存技术与实时质量监测相结合，以最大限度地减少收获后损失，延长保质期，并确保大豆对全球粮食和营养安全的贡献。
