A secondary benefit is the omission of chemical addition. Membrane-based clarification exhibits a high technical readiness level of 6 or 7. Pilot cases have demonstrated the ability of UF to reduce turbidity by &gt;98 % while significantly decolorizing the juice. In this paper, five processes using UF-clarification at the pilot plant scale are reviewed. Two of the pilot processes focused on softening and filtering the sugarcane juice to reduce the polyvalent ion concentration. While another two processes focused on decolorization by size exclusion of impurities with tighter membranes. The final white sugar products from the different pilot processes were between 60 and 600 International Color Units. The lowest color is achieved by an integrated membrane process for clarification, decolorization, and concentration. The two main recommendations for the operation of UF-clarification are (1) pre-filtering the raw sugarcane juice (by screens or centrifugation) and (2) optimizing membrane cleaning protocols. For clarification, the specified membrane molecular weight cut-off should be between 65 and 3000 kDa to achieve a permeate flux for sugarcane juice between 35 and 125 L/(m² hr). Polymeric spiral wound, tubular ceramic, and tubular stainless steel UF membranes are technically suitable options for sugarcane juice clarification. By combining ultrafiltration modeling, which accurately predicts system design and operating parameters, with machine learning models, model predictive controls of sugarcane processes can be achieved. Developmental work utilizing the clarification byproduct in soil application shows promise.</div></div>","PeriodicalId":359,"journal":{"name":"Journal of Food Engineering","volume":"402 ","pages":"Article 112693"},"PeriodicalIF":5.3,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144280789","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}

By addressing a typically discarded agricultural waste, this work not only contributes to waste reduction but also promotes the development of plant-based bioactive ingredients. Although the TCM extract exhibits strong antioxidant activity, its low stability under gastrointestinal conditions limits its application. To overcome this, phenolic compounds were extracted using ultrasonic-assisted extraction (60 % v/v ethanol) and encapsulated via complex coacervation to enhance their stability and delivery. Microcapsules were formed using soy protein isolate (SPI) with gum arabic (GA), inulin (IN), or sodium alginate (SA), and different core concentrations were tested. The SPI-inulin formulation at 0.1 % core concentration exhibited the highest encapsulation efficiency (98.74 %) and antioxidant recovery after <em>in vitro</em> digestion. These microcapsules also demonstrated favorable physicochemical characteristics, such as small particle size and positive surface charge, contributing to their structural stability. The results suggest that SPI-inulin-based microcapsules are particularly effective in protecting phenolic compounds during digestion and enhancing their potential bioavailability.

To address this issue, a simple approach was proposed in this study, which involves whipping hybrid gels to generate foamed emulsions and adjusting the component proportions of the gels to regulate both the physical properties and types of foamed emulsions. Specifically, hybrid gels were prepared by homogenizing the candelilla wax-based oleogel and glycyrrhizic acid-based hydrogel, followed by whipping these hybrid gels to produce foamed emulsions. The influence of the oleogel-to-hydrogel ratios on the physical properties of hybrid gels and foamed emulsions was investigated. Results demonstrated that increasing the ratio from 3:7 to 7:3, and then to 8:2 resulted in a catastrophic phase inversion of hybrid gels, transitioning from O/W to bicontinuous, and finally to W/O type. Foamed emulsions with aqueous continuous phase were derived from O/W type hybrid gels, where partially coalesced oleogel droplets stabilized these bubbles. Moreover, the foamed emulsions with oil continuous phase were prepared by whipping the bicontinuous or W/O type hybrid gels wherein wax crystals anchored on the bubble surface. Small amplitude oscillatory shear (SAOS) and large amplitude oscillatory shear (LAOS) test results illustrated that foamed emulsions with aqueous continuous phase demonstrated superior mechanical strength and deformation resistance compared to their oil continuous phase counterparts, making them ideal ink for 3D printing. These findings enrich the formulation of foamed emulsions, enabling their use in developing low-fat, low-sugar foods as well as customized food processing.</div></div>","PeriodicalId":359,"journal":{"name":"Journal of Food Engineering","volume":"402 ","pages":"Article 112690"},"PeriodicalIF":5.3,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144297279","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}

Each method has strengths and limitations, yet discrepancies in measurements remain poorly understood. This study aimed to investigate the agreement and differences among these techniques in characterizing dried apples and pears dehydrated using hot air-drying (HAD), blast freeze-drying (BFD), and liquid nitrogen freeze-drying (FDN). The bulk density of freeze-dried apples and pears was approximately 0.14 and 0.18 g/ml, respectively, while HAD apples and pears averaged 0.54 g/ml and 1.12–1.29 g/ml. Particle densities measured by MIP and pycnometry were similar, but micro-CT produced different values. For HAD apples, porosity values were 62.3 % (pycnometry), 59.6 % (MIP), and 54.6 % (micro-CT). For FDN pears, the values were 83.5 %, 83.3 %, and 70.9 %, respectively, while for BFD pears, they were 86.1 %, 86.0 %, and 72.1 %. The discrepancies in micro-CT results may stem from resolution limitations or image processing techniques. The findings of this study suggest that care should be taken when selecting and applying micro-CT to characterize dried food porous microstructures. To ensure the comprehensive characterization of dried food porosity, micro-CT should be combined with pycnometry or MIP. This combination provides a more accurate quantification of pore volume and size and a deeper and more reliable understanding of porous structures, leading to improved food quality, efficiency in production, and innovation in food processing technologies.</div></div>","PeriodicalId":359,"journal":{"name":"Journal of Food Engineering","volume":"402 ","pages":"Article 112688"},"PeriodicalIF":5.3,"publicationDate":"2025-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144270236","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}

As a result, the relationship between EC and temperature cannot be accurately determined. In addition, for cake batter, starch gelatinization occurs during the measurement, leading to more complex EC curves. To address these issues, this study proposes a numerical method for determining EC that accounts for temperature non-uniformity. This model is coupled with a starch gelatinization model. The principle is based on the estimation of the EC using the method of least squares between the experimental temperature and the numerical one. The estimation of the EC of the cake batter consists of two steps: first, the device was characterized with xanthan and potassium chloride solutions of known electrical conductivities. A conversion efficiency of 0.77 was found. This efficiency was used to estimate the EC of the cake batter as a function of temperature and for different electric fields.

Despite advancements in food engineering, research focused on effective odor control in algal-based functional foods remains limited. This study utilizes machine learning to analyze the molecular structures of algal-derived odor compounds, aiming to enhance sensory quality through targeted processing methods. Molecular descriptors were extracted using RDKit from compounds in the OlfactionBase and PubChem databases, followed by visualization with t-distributed stochastic neighbor embedding (t-SNE), revealing distinct clustering patterns for specific odor profiles. Six machine learning algorithms, including Gaussian Naive Bayes, Random Forest, Support Vector Machine, k-Nearest Neighbors, Stochastic Gradient Descent, and Gradient Boosting Decision Trees, were evaluated for classification accuracy. Initially, a binary classification model was constructed to differentiate between “Ammonia-like” and “Rancid” odors. To further enhance model generalizability, an additional odor class (“Other”) was incorporated to reflect non-typical or mixed odor profiles, resulting in a multiclass classification task. Feature selection and dimensionality reduction were conducted using RFECV and PCA, respectively, followed by model training and validation. In the binary classification task, the k-Nearest Neighbors model demonstrated superior performance, achieving accuracies of 94.25 % and 93.11 % in 3-fold and 5-fold cross-validation, respectively. In multi-classification tasks, Stochastic Gradient Descent achieves the best results.
