Therefore, the objective of this work was to evaluate the technique of hyperspectral imaging for studying the hydration kinetics of pinto beans. For this purpose, a sample of pinto beans was hydrated in distilled water, determining moisture content during the process and taking hyperspectral images by reflectance mode, in the range 400 to 800 nm until constant mass. The moisture content was modelled using Peleg and a sigmoidal model. Next, the images were pre-treated and the median spectral profile for each bean was obtained. Then, a regression model was fitted, using the wavelength that maximized the coefficient of determination (<em>R</em><sup>2</sup>) and minimized the root mean square error (<em>RMSE</em>). The results show that Peleg model fit experimental data with <em>R</em><sup>2</sup> in the range of 0.974 to 0.989 while sigmoidal model of 0.997 to 0.999. On other hand, mean spectral profiles at 632 nm and sigmoidal model give the higher metrics 0.997 and 38.3 for <em>R</em><sup>2</sup> and <em>RMSE</em> respectively.

In this study, we measured the dielectric properties (dielectric constant and loss factor) of eight fruit juices (passion fruit, melon, pineapple, cashew, orange, lemon, acerola, and guava) using an open-ended coaxial-line technique for temperatures ranging from 5 to 90 °C at commercial frequencies of 915 and 2450 MHz, alongside electrical conductivity. These properties were successfully correlated with the temperature for each individual juice; then, machine learning techniques (random forest, gradient boosting machine, and multilayer perceptron) were used to predict the properties of this diverse group of eight juices based on various physicochemical measurements. These techniques revealed temperature and electrical conductivity as the most critical predictors, while total solids, pH, acidity, ashes, and select color parameters also emerged as significant variables. These findings demonstrate that the integration of physicochemical analyses with machine learning tools offers an objective approach to correlate and predict dielectric properties for a group of food products, facilitating adjustments in product composition without additional measurements, thus enhancing the efficiency and accuracy of microwave-assisted thermal processing simulations and optimizations.</p></div>","PeriodicalId":100898,"journal":{"name":"Measurement: Food","volume":"14 ","pages":"Article 100158"},"PeriodicalIF":0.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S277227592400025X/pdfft?md5=f7951dde66933da4ce07f39653104f5a&pid=1-s2.0-S277227592400025X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140209416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The investigation of the potential therapeutic effects of plants within this scope is important in terms of their utilisation as natural resources. In this study, a compilation of research conducted on <em>Cuminum</em> species in the literature is presented. Within this context, the utilisation areas, general characteristics, biological activities, and chemical contents of Cuminum species have been compiled. According to the literature, it has been determined that spices are particularly utilised in the fields of cosmetics, disease management, and culinary arts. Furthermore, it has been observed that they are significant sources in terms of anticancer, antioxidant, and antimicrobial properties. It has been observed that the compound with the highest concentration in its constituents is cuminlaldehyde (19.9–64.31 %). When necessary studies and procedures are applied based on literature data, <em>Cuminum</em> species serve as important natural resources in pharmacological designs.</p></div>","PeriodicalId":100898,"journal":{"name":"Measurement: Food","volume":"14 ","pages":"Article 100157"},"PeriodicalIF":0.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772275924000248/pdfft?md5=c221444fbe789447d297c6bbdfb3d920&pid=1-s2.0-S2772275924000248-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140191092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
