This study investigated the interactive effects of microwave power and pulse ratio on various properties of potato slices during drying. The drying process was further modeled using moving boundary conditions to assess the influence of these variables on heat and moisture diffusion. Results demonstrated that increasing microwave power and decreasing the pulse ratio significantly reduced drying time due to intensified effective moisture diffusion coefficient (14.28%). Enhanced product quality—evidenced by minimized shrinkage (26.28%), reduced bulk density (13.22%), and improved rehydration ratio (28.96%)—alongside increased energy efficiency, was observed with higher power levels and pulse ratios. Additionally, a higher pulse ratio intensified the electric field due to shorter microwave “on” durations, promoting a more uniform wave distribution within the product. Unlike convective air drying, where moisture removal initiated from the food's edges, the combined microwave-air drying approach exhibited a distinct moisture migration pattern attributed to the volumetric heating mechanism of microwaves, which directed heat transfer from the interior to the surface of the potato slices. The model's performance, evaluated using R<sup>2</sup> and RMSE metrics, was deemed satisfactory. Overall, this research highlights the importance of optimizing microwave power and pulse ratio for the efficient production of high-quality potato chips.</div></div>","PeriodicalId":10939,"journal":{"name":"Current Research in Food Science","volume":"10 ","pages":"Article 101013"},"PeriodicalIF":6.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143528730","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}

Both correlation analyses on the response parameters and parameter variance are studied to distinguish the product sets. Strong correlations are found between anisotropy-related parameters, such as fibre score in macrostructure, air anisotropy in microstructure, and the toughness anisotropy index from mechanical properties. Some correlations are found to be product-set independent, such as air bubble anisotropy and fibre score, indicating universal relationships within this study, while other correlations are product-set dependent, such as between fibre score and the anisotropy index of the Young's Modulus in the mung bean fine fraction product set.

This article used menthol as the research subject and investigated the binding effects of three different CDs through experiments and computer simulations.

The results indicated that the IC formed between β-CD and menthol (menthol/β-CD-IC) is the most stable, with a binding free energy (ΔGbind) of −7.27 kcal/mol. The IC formed between α-CD and menthol (menthol/α-CD-IC) is the least stable one (ΔGbind = 2.59 kcal/mol).
