However, broader consumer adoption hinges on their ability to closely mimic the textural and sensory properties of real meat. While textural characterisation of HMMA, including hardness, springiness, chewiness, and cutting force, has been reported, optimising HMMA production to achieve these properties remains a challenge. This study presents a human-guided multi-objective Bayesian optimisation (MOBO) framework to optimise the textural properties of HMMAs that were produced by high-moisture extrusion cooking. A Gaussian process surrogate model was employed to map the relationship between extrusion parameters (moisture content, barrel temperature, and screw speed) and HMMA textural properties, and the MOBO framework used this surrogate model to generate promising candidates for the subsequent trials. The objective was for HMMAs to attain the texture of cooked chicken breast meat. Our results demonstrated the effectiveness of MOBO in guiding the optimisation process. The Pareto front, a set comprising optimal trade-off values of hardness and cutting force such that improving one necessarily degrades another, was monitored across multiple trials, converging towards the desired target values for hardness and cutting force with a range of difference between −5.23% and −7.10% and −14.67%–7.33%, respectively. This proof-of-concept framework lays the groundwork for future studies exploring more complex extrusion parameters and expanding the range of targeted meat analogues.</div></div>","PeriodicalId":359,"journal":{"name":"Journal of Food Engineering","volume":"396 ","pages":"Article 112566"},"PeriodicalIF":5.3,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143592664","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}

Conventional measuring techniques like scanning electron microscopy (SEM), light microscopy (LM), confocal laser scanning microscopy (CLSM) and transmission electron microscopy (TEM) have been widely used to investigate the internal and structural characteristics of dried agricultural products. However, these conventional measuring techniques have some limitations, which include the destruction of the food samples, sample preparations, and the development of artifacts. In order to overcome the limitations of conventional measuring techniques, non-invasive measuring techniques like X-ray microcomputed tomography (XCT), low-field nuclear magnetic resonance (LF-NMR), magnetic resonance imaging (MRI) and neutron imaging have been used to investigate the internal changes of agricultural products during drying in ex-situ and in-situ. However, the use of these non-invasive measuring techniques has yet to gain wide acceptance and utilization in the drying of agricultural products. Therefore, the purpose of this paper is to review the applications, advantages and limitations of XCT, LF-NMR/MRI and neutron imaging in the drying of agricultural products. The information contained in this review would enhance further developments and applications of these non-invasive measuring techniques in the drying of agricultural products. The review also shows that the non-invasive techniques could provide information on the drying properties (drying kinetics, porosity, pore size, wall thickness, moisture profile, local water distribution, shrinkage and moisture distribution) of food products subjected to drying in ex-situ and in some cases in in-situ.</div></div>","PeriodicalId":359,"journal":{"name":"Journal of Food Engineering","volume":"396 ","pages":"Article 112558"},"PeriodicalIF":5.3,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143601786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Food simulants, including deionized water representing aqueous food, 3% acetic acid representing acidic food, and 50% ethanol representing alcoholic food, were used for pouching and packaging of the PVA-coated composite films. The films were also subjected to water bath (80 °C for 30 min) and accelerated treatment (80 °C for 60 min and 100 °C for 60 min) to simulate industrial pasteurization and more severe damage. The morphology, chemical composition, thermal stability, barrier properties, and other characteristics of the materials were evaluated. In this study, it was found that all three simulants had an effect on the barrier properties of the films. Among them, acidic and alcoholic simulants had a relatively large impact on the oxygen barrier properties of the films, with decreases of 44.99% and 79.48%, respectively. The alcoholic simulant also had the largest effect on the moisture barrier properties of the films, with a decrease of 28.33%. Additionally, the addition of the three food simulants led to a significant reduction in the mechanical properties of the films and a significant decrease in transmittance. Microstructural characterization revealed that the above performance changes originated from the harsh conditions when the food simulants first contacted the base film, damaging the internal structure. Subsequently, the barrier layer PVA was penetrated and dissolved, thus affecting the performance. The fragmentation of thin film crystals and the penetration of the simulant were also evidenced by XRD and FTIR.

Previously, a combined sweeping and complementary relative phase strategy was used to deliver more uniform heating than microwave heating processes using fixed or orderly sweeping relative phases. However, extensive relative phase sweeping (e.g., ∼44% of the 3-min whole heating time) is needed to collect relative phase-dependent thermal contributions to implement the complementary strategy. This limitation can be addressed by utilizing the constructive and destructive dual-port microwave interactions to develop a more efficient complementary strategy. Built upon the observation that the spatial microwave power dissipation density varies in a sinusoidal wave shape, this study developed a Predictive-Complementary relative phase strategy. Instead of collecting relative phase-dependent thermal contributions using extensive relative phase sweeping, the predictive approach only collected three thermal contributions at relative phases of 0°, 90°, and 180° and then predicted all others for implementing the complementary strategy. The predicted thermal contributions were validated by comparing them with the experimentally collected ones in dual-port microwave heating of gellan gel samples, which showed good correlations with R² values between 0.91 and 0.97 and Root Mean Square Error (RMSE) values between 0.17 and 1.02 °C. By comparing with other reported Fixed, Sweeping, and Sweeping-Complementary relative phase strategies, the Predictive-Complementary relative phase strategy devoted ∼83% of the 3-min heating time in the complementary shifting stage and showed the best microwave heating uniformity and power absorption efficiency. The Predictive-Complementary relative phase strategy presented an efficient approach to predicting relative phase-dependent thermal contributions for more uniform microwave heating using complementary relative phases. The algorithm can be integrated as an advanced relative phase heating strategy in smart solid-state microwave systems.</div></div>","PeriodicalId":359,"journal":{"name":"Journal of Food Engineering","volume":"395 ","pages":"Article 112544"},"PeriodicalIF":5.3,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143488834","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}
