Microwave pretreatment conditions, including processing time and power levels (120, 400, 640, and 800 W), were examined for their impact on texture softening efficiency, microstructure, β-carotene content, and color. Regression analysis confirmed that processing time substantially influenced carrot hardness, with higher the softening rate increasing as microwave power levels rose from 120 to 800 W. The log-linear model demonstrated a strong correlation coefficients (<em>R</em><sup>2</sup> = 0.9732–0.9407) across different power levels, confirming its reliability in achieving the target texture. The derived times, based on a log-linear model, successfully reached a target hardness of 5.0 × 10<sup>4</sup> N/m<sup>2</sup> (KS level 2), with times of 371 s at 120 W, 198 s at 400 W, 72 s at 640 W, and 61 s at 800 W. The samples pretreated for the derived times corresponding to 120, 400, 640, and 800 W exhibited varying porosity levels, influencing the quality of enzyme-infused carrots. With increasing microwave power, the microwave-pretreated carrots showed improved color (more yellow and red) and preservation of β-carotene, potentially linked to shorter processing times. These results suggest that microwave pretreatment followed by enzyme infusion is an efficient approach to softening carrot texture without compromising its quality, and the log-linear model offers a predictive framework for modifying food textures in dysphagia management.</div></div>","PeriodicalId":329,"journal":{"name":"Innovative Food Science & Emerging Technologies","volume":"98 ","pages":"Article 103865"},"PeriodicalIF":6.3,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142655818","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}

The transmitting units are placed at heating materials regions, utilizing the characteristics of time-reversal spatial focusing and the principle of electric field superposition to achieve multi-objective directional heating. These transmitting units radiate electromagnetic waves sequentially, while receiving units collect and process the information from the transmitting units, then send it back into the cavity, enabling multi-objective directional microwave heating. To validate the proposed method, both simulations and experiments were carried out. The heating performance was measured by infrared thermal imager and thermocouple. The results demonstrate that the method effectively achieves multi-objective directional heating. Additionally, the strategy of introducing an aluminum block inside the cavity to enrich the scattering environment and thereby improve the time reversal heating effects were also verified through simulations and experiments.
