Therefore, it is necessary to explore a cryoprotectant to improve cell survival during the process. This research aimed to explore the optimal cryoprotectant formulation of <em>L. acidophilus FMNS-10</em> and its protection mechanism. The optimal cryoprotectant consisted of 10.7 % skim milk, 3 % sodium L-glutamate and 10 % D-trehalose, resulting in a survival rate of 91.69 % for <em>L. acidophilus FMNS-10</em> after freeze-drying (<em>p</em> &lt; 0.05). Under this condition, the integrity of cell wall and membrane of <em>L. acidophilus FMNS-10</em> was close to that of the fresh strain, which could be attributed to preventing ice crystal formation. Cryoprotectants demonstrated a significant protective effect on enzymatic activities. In the cryoprotectant-free group, the activities of β-galactosidase, L-LDH, Na⁺/K⁺-ATPase and the concentration of Ca²⁺ decreased by 36.19 %, 51.82 %, 89.40 %, and 41.90 %, respectively. However, the cryoprotectant group were only 7.10 %, 1.66 %, 7.41 %, and 4.10 % reductions compared to the cryoprotectant-free group (<em>p</em> &lt; 0.05). These results indicated that the optimal cryoprotectant improved the survival rate of <em>L. acidophilus FMNS-</em>10 by inhibiting the loss of enzyme activity. In addition, the optimal cryoprotectant significantly mitigated the DNA damage induced by freeze-drying. The reduction in enzyme and DNA damage may be attributed to complex cryoprotectants maintaining the stability of their three-dimensional structures and reducing structural disruption caused by freezing. Further analysis of storage stability revealed that the viable count of <em>L. acidophilus FMNS-10</em> exceeded 10⁷ CFU/mL when stored at −20 °C for 180 days. These findings provide a comprehensive theoretical foundation for how to freeze-dry <em>Lactobacillus acidophilus.</em></div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"112 ","pages":"Article 102646"},"PeriodicalIF":2.7,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876727","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}

Still, post-harvest losses caused by insect pests, such as the rice weevil (<em>Sitophilus oryzae</em> L.), significantly compromise grain quality and storage. Conventional pest control methods, particularly chemical insecticides, pose environmental and health risks, highlighting the urgent need for safer alternatives. This study assessed the efficacy of silicon nanoparticles in controlling weevil infestations and investigated their residual and physicochemical effects on wheat grains. Laboratory experiments were conducted using silicon powder at various concentrations, with untreated grains as control. Over 15 days, mortality rates, grain weight loss, and damage were recorded. The results demonstrated that higher concentrations of silicon, particularly 700 and 1000 ppm, achieved complete pest mortality within 5 days. Both weight loss and grain damage were significantly reduced at these concentrations, with the lowest rates observed at 0.50 % for weight loss and 0.44 % for damage at 1000 ppm. Additionally, the study examined the physicochemical properties of the silicon-treated grains, including moisture content, bulk density, porosity, and water uptake. The measurements were taken on the first day and again on the 180^th day of storage. While storage-induced changes were noted in treated and untreated grains, no adverse impacts on grain quality were identified. Residual silicon analysis using scanning electron microscopy-energy dispersive X-ray spectroscopy confirmed effective removal following double washing, ensuring the treated grains comply with safety standards. In conclusion, the findings suggest silicon nanoparticles represent a promising, residue-free, and environmentally sustainable approach to post-harvest pest management, effectively preserving grain quality while mitigating pest-induced losses.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"112 ","pages":"Article 102664"},"PeriodicalIF":2.7,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143868404","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}

Fresh-cut processing favors convenience but accelerates leaf senescence and quality degradation, contributing to consumer rejection and postharvest losses and waste. Turnip greens, cultivated year-round in different regions, are exposed to variable growing conditions across seasons. While seasonal variations in nutritional and organoleptic quality are documented for other species during postharvest storage, this has not been investigated in turnip greens in fresh-cut format. In this study, turnip greens grown in two seasons—fall and winter-spring—were fresh-cut processed and stored at 5 °C for up to 21 days. Subjective (marketability scores), and objective (color, total chlorophyll, carotenoids, polyphenols and ammonia contents) parameters were monitored at 0, 7, 14, and 21 days of storage. Results showed that while sensory quality declined during storage in both seasons, leaves grown in the fall exhibited a significantly faster deterioration rate compared to winter-spring samples. This trend mirrored the higher rates of chlorophyll and fresh weight loss shown by turnip greens grown in the fall. Seasonal variations in environmental factors and agronomic practices likely induced distinct physiological responses, influencing postharvest quality and shelf-life. This is the first report of organoleptic and compositional quality changes in fresh-cut turnip greens affected by the growing season. Tailoring postharvest practices to seasonal shelf-life variations can contribute to minimizing food losses and optimizing produce supply chain performance.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"112 ","pages":"Article 102661"},"PeriodicalIF":2.7,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143859203","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}
