Herein, the effects of different degrees of milling (DOMs) (0%–15.0%) on the texture, nutritional quality, and aroma properties of KSR were investigated. As DOMs increased, the brightness (<em>L∗</em>) values of rice raised, while the red/green (<em>a∗</em>) and yellow/blue (<em>b∗</em>) values decreased. Twenty-one volatile compounds were identified in KSR using gas chromatography–mass spectrometry. The unique flavor compounds 2-acetyl-1-pyrroline, hexanal, nonanal, octanal and 2-pentylfuran were found in brown rice. With an increase in DOM, the types and contents of most fragrant volatiles decreased. Textural analysis showed that the hardness and chewiness of the cooked KSR decreased but cohesiveness and springiness increased with an increase in DOMs. The peak pasting viscosity increased by 20.76% when the DOM was changed from 0% to 15.0%. With the removal of protein, lipid, and dietary fiber, the <em>in vitro</em> digestibility increased by 9.98% after 180 min compared with brown rice.

There were no significant differences in bioaccessibility and uptake efficiency between RS and WWF pasta. Antioxidant actions of carotenoid against AAPH-induced oxidative stress showed an efficient cytoprotective effect and intracellular oxidative stress attenuation. This was, however, flour type and concentration dependent. Intricate physical and chemical structural changes in the pasta matrix might have accounted for the observed differences. Hence, carotenoid absorption and protection against oxidants are mediated by pasta cooking and the overall food matrix, as they affect the digestive outcome of carotenoids. Understanding the effects of food processing can help improve the functionality of pasta carotenoids and enhance their ability to reach target organs and promote optimum health.</div></div>","PeriodicalId":15285,"journal":{"name":"Journal of Cereal Science","volume":"120 ","pages":"Article 104037"},"PeriodicalIF":3.9,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142433913","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}

The changes indicated that low level of WBDF induced a more compact protein secondary structure to inhibit protein digestion. Conversely, in noodles with high level of WBDF (>6%), the looser protein secondary structure partially alleviated the inhibitory effect of WBDF on protein digestion, which was caused by part of WBDF penetrating the protein's hydrophobic core.
