These methods, being eco-friendly, effectively inactivate microorganisms and enzymes without compromising the sensory and nutritional qualities of juices. Among these, pulsed magnetic field (PMF) technology is a promising technique that involves exposing liquid foods to a magnetic field in the form of pulses, exhibiting a bactericidal effect without any rise in temperature. The study aimed to develop a PMF processing system capable of generating low-frequency, high-intensity oscillating magnetic fields and optimized its application on orange juice at varying concentrations (10%, 15%, and 20%), magnetic field intensities (2, 4, and 6 T), and treatment times (5, 10, and 15 min). Additionally, the process conditions were optimized to preserve the nutritional quality, sensory properties, and microbial safety of orange juice. Fresh orange juice had an initial bacterial load of 2.09 × 10<sup>6</sup> CFU/mL, which was reduced to 1.43 × 10<sup>4</sup> CFU/mL at 4 T for 15 min in 15% juice. Similarly, yeast and mold counts decreased from 1.85 × 10<sup>5</sup> to 1.68 × 10<sup>4</sup> CFU/mL in 20% juice. The nonthermal nature of PMF was confirmed by negligible temperature rise. Posttreatment, <i>L</i>-values ranged from 82.4 to 83.79, decreasing to 80.2–82.55 during storage, while <i>b</i>-values ranged from 16.48 to 16.96, slightly reducing to 16.34–16.86. Viscosity for 10% juice ranged from 0.0645 to 0.0687 Pas posttreatment, reducing to 0.06–0.0648 Pas after 10 days. Minimal pH variation was observed. The optimal PMF treatment (4 T, 15 min, 20% concentration) effectively reduced microbial load while preserving juice biochemical (pH, color) and rheological (viscosity) during storage at 4°C. PMF-treated orange juice showed minimal changes in color, viscosity, and microbial stability during refrigerated storage. The absence of heat-related degradation ensures retention of quality attributes. This study demonstrates that PMF is a viable, nonthermal alternative for processing high-acid fruit juices, providing a balance between microbial safety and quality preservation.</p>\u0000 </div>","PeriodicalId":15932,"journal":{"name":"Journal of Food Process Engineering","volume":"48 5","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During harvesting or transportation, kiwifruit sustained surface invisible damage due to collisions or pressure. To conduct non-destructive detection of minor mechanical damage in kiwifruit, this study investigated two widely cultivated varieties in China. Near-infrared spectroscopy was employed to collect spectral data from both intact samples and early-damaged samples. These datasets were utilized to develop classification models aimed at assessing the extent of damage in kiwifruit. Initially, the first derivative method was applied as a spectral preprocessing technique. Three feature selection methods—Competitive Adaptive Reweighted Sampling (CARS), Genetic Algorithm (GA), and Bootstrap Soft Shrinkage (BOSS)—were implemented to extract characteristic wavelengths from the preprocessed spectra. Subsequently, classification models were constructed based on both the selected feature spectra and the original spectra. A novel Stacking ensemble model was developed using Support Vector Machine (SVM), Extreme Learning Machine (ELM), and Extreme Gradient Boosting (XGBoost) as first-level classifiers, with Logistic Regression serving as the second-level classifier. By establishing training and testing datasets while comparing performance metrics against those of individual first-level classifiers, the study evaluated the model's efficacy. The results indicated that the Stacking model consistently demonstrated high accuracy across all feature selection algorithms; notably, when combined with CARS feature selection, it achieved accuracy rates of 100% and 98.60% on training and testing sets, respectively, underscoring its superior performance. This suggested that integrating the Stacking model with CARS provided optimal predictive capabilities for this dataset.

In Sub-Saharan Africa, where the loss of fruits and vegetables can be particularly high, incorporating cold chain systems into value chains is an important strategy. Nevertheless, the absence of fundamental infrastructure and managerial expertise required to facilitate the advancement of cohesive cold chains, especially in rural regions, poses a substantial obstacle. Evaporative cooling has been suggested as an inexpensive cooling substitute for increasing the shelf life of fresh fruits and vegetables in hot, dry climates. Evaporative cooling is not a new concept; its use in buildings can be traced back thousands of years. However, renewed interest is spurring innovation in evaporative-cooling technologies. This comprehensive review explores the fundamental concepts and applications of different classes of evaporative cooling systems, with a particular focus on the preservation of postharvest quality of fruits and vegetables, and its economic implications. In addition, the review discusses the role of desiccant/dehumidification systems in improving the performance of evaporative cooling and furthermore presents a decision support system as a tool that promotes the effective use of evaporative coolers. The review underscores the potential of evaporative coolers as a viable solution for short-term postharvest preservation of horticultural produce. This system not only significantly lowers storage temperature, but also elevates the relative humidity within the storage environment, a critical factor in preserving the freshness and quality of the stored commodities.
