Even moderate impacts can lead to internal damage, significantly affecting the shelf life and quality of the fruit. In recent years, technologies such as spatial frequency domain imaging and structured light reflection imaging have made progress in early damage detection. However, considering both economic feasibility and practical applicability, there remains a need to explore accurate and quantitative methods for damage assessment. To address this issue, this study constructed a 3D model of ‘Red Fuji’ apples through physical experiments and reverse engineering. Explicit dynamic simulations based on the finite element method were conducted to evaluate the mechanical damage under various impact conditions. A total of 125 simulation scenarios were designed by combining five impact heights, five impact angles, and five contact materials. Key data and visual representations of stress evolution were obtained from the simulations. Results indicated that the highest damage susceptibility occurred when apples impacted steel at a height of 20 cm and an angle of 135°, while the lowest damage susceptibility was observed when impacting polyvinyl chloride at a height of 15 cm and an angle of 90°. Furthermore, a response surface methodology was employed to analyze the quantitative values of damage susceptibility. The maximum discrepancies between experimental and simulated results in terms of damage depth, area, and volume were 0.90 cm, 2.94 cm², and 11.85 cm³, respectively. The prediction error of damage susceptibility ranged from 0.883 to 11.3 %. The consistency of the damage patterns further validates that the finite element model can effectively simulate apple damage under specific impact scenarios. This study provides insights for reducing mechanical damage during harvesting.</div></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"113 ","pages":"Article 102677"},"PeriodicalIF":2.7,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143917838","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}

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).

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.
