Among 3 types of polysaccharides (tested konjac gum, soluble soybean polysaccharide, and PUL), the PUL-APE composite film demonstrated superior film performance. The effects of APE concentrations at 1, 2, 3, 4, and 5 % (<em>w/v</em>) on the barrier, mechanical, physical, and optical properties of the developed films were evaluated while exploring intermolecular interactions between APE and polysaccharides. Results revealed that increasing APE concentration significantly enhanced the thickness, moisture content, and water solubility of PUL-APE composite films while decreasing brightness and opacity rate (<em>P</em> &lt; 0.05). Compared to other groups, the composite film containing 3 % APE exhibited superior barrier and mechanical properties with a minimum water vapor permeability value of 2.35 ± 0.05 g/m² and maximum tensile strength value of 55.82 ± 0.42 MPa. Additionally, the packaging effect of PUL-APE composite film on chilled PLL samples was investigated. The film effectively delayed microbial growth and minimized oxidative rancidity, texture changes, and cooking loss during refrigerated storage of PLL samples. Therefore, these PUL-APE composite films hold great potential as edible materials for meat packaging applications.</div></div>","PeriodicalId":389,"journal":{"name":"Meat Science","volume":"225 ","pages":"Article 109801"},"PeriodicalIF":7.1,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143620552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This enhancement method considered the position shift and uneven colour presentation of sensitive points during the preparation and reaction of olfactory visualization sensor array. Based on the enhanced images, three advanced deep learning models (InceptionNetV3, ResNet50 and MobileNetV3) were established, and compared with three traditional machine learning models of partial least squares regression (PLSR), support vector regression (SVR) and random forest (RF) based on manually extracted colour space features.
