The system consists of an image acquisition subsystem and an impurity classification subsystem, which aim to accurately evaluate the quality of paddy grains. The image acquisition subsystem is composed of a multi-degree-of-freedom manipulator, a flexible vibrating disc, an industrial camera, a light source, and an embedded computing platform. The multisensor fusion technology is used to realize the two-dimensional imaging of the target paddy. Moreover, the impurity classification subsystem innovatively adopts the feature extraction method based on convolutional neural network to realize the fast and accurate classification of paddy impurity images. To balance the classification accuracy and computational complexity, we use GhostNet as the backbone network for efficient high-dimensional semantic feature extraction from paddy images. Furthermore, the visual attention mechanism and multiscale feature aggregation strategy are introduced to enhance the extracted features and improve the accuracy of impurity classification. The image acquisition subsystem collects 256 raw images with a resolution of 5120 × 5120. After image preprocessing, a total of 5000 paddy image blocks are obtained, and each block has different resolutions. These image blocks include lesion paddy images, moldy paddy images, sprout paddy images, immature paddy images, and normal paddy images. The trained impurity classification model achieves 83.64% precision, 83.60% recall, 83.54% <i>F</i>1 score, and 93.44% accuracy. These results not only show the efficiency and accuracy of the system in practical applications but also provide important reference value for future research and application in a wider range of agricultural detection fields.</p>","PeriodicalId":15717,"journal":{"name":"Journal of Food Processing and Preservation","volume":"2025 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/jfpp/2338160","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145012634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is difficult to prevent the intake of food allergens due to the complex nature of food products. Food researchers are striving to find innovative techniques to remove allergy-causing agents and produce nonallergenic food products. The prime objective of this study was to assemble the latest information to produce hypoallergenic food with the help of emerging technologies including irradiation, high-pressure processing (HPP), pulsed ultraviolet light (PUL), pulsed electric fields (PEFs), cold plasma, ultrasound, and their combination. Classification of food allergy, epitope description, identification method, and clinical manifestations are also presented. Studies showed that processing technologies reduce allergenicity while retaining the sensory and nutritional integrity of food products. The effectiveness of each method appears to be highly dependent on the specific food matrix, the type of allergen, and the processing parameters used. Among the technologies discussed, cold plasma, HPP, and ultrasound demonstrated the most significant reduction in food allergenicity, while irradiation and PEF were less effective. Notably, combining multiple nonthermal technologies emerged as the most promising strategy to develop hypoallergenic foods with minimal compromise to quality.

The use of a solar dryer for multicrop may also make this technology cost-effective. In fact, the performance evaluation of a solar dryer for different fruits and vegetables promotes the usability of a dryer for crops. Hence, in this study, a newly developed natural convection solar dryer has been evaluated for drying cabbage. Cabbage samples were pretreated with a brine solution (with 5% [<i>w</i>/<i>w</i>] NaCl) followed by blanching. Pretreated samples were dried both in the dryer and open sun. Control samples were also dried in the solar dryer and open sun. The cabbage was dried in single and multilayer arrangements, maintaining thin layer drying thickness. Temperature distribution in and outside of the dryer was also investigated during the experiment, both spatially and temporally. The acceptability of dried cabbage was checked using a 9-point hedonic scale test. The experimental value of the moisture ratio was fitted with four different thin layer drying models—Newton, Page, modified Page, and Henderson. The drying air temperature consistently exceeded the ambient temperature by approximately 1°C–35°C, depending on the intensity of solar radiation. Drying efficiency for single-layer and multilayer arrangements were 25.25% and 43.57%, respectively. Hence, multilayer drying of cabbage in the dryer can be an effective means of drying with higher efficiency. From the acceptability test, it was found that solar dried pretreated cabbage was mostly liked. The best fitted model was the Page model for both single and multilayer drying.

Consequently, the potential for producing phenolic extract from OMWW is substantial. Membrane processing stands as a viable technology for the recovery of phenolic compounds from OMWW. In this study, the extraction of phenolic compounds through membrane processes was carried out employing enzyme and solvent pretreatments for two olive cultivars (Koroneiki and Roghani). The extraction methods were assessed by determining the total polyphenol content, extraction efficiency, and antioxidant activity of the extract. Statistical analysis revealed that the extraction method and its interaction with the cultivar significantly impacted the extraction efficiency, while the effect of the cultivar itself was not significant. Across both cultivars, the enzymatic pretreatment method exhibited the highest extraction efficiency and phenolic compound content. Additionally, it was found that the Koroneiki cultivar had a higher amount of phenolic compounds than the Roghani cultivar. The enzymatic pretreatment achieved the highest extraction efficiency (75.5%) and phenolic content (1631.7 mg/L). The enzymatic pretreatment exhibited a lower value for the radical scavenging activity of the phenolic compound extract, whereas the iron reducing power of the phenolic compound extract was the highest with enzymatic pretreatment.
