In this study, flexible V-type starch was utilized to adsorb heptanal and 1-octen-3-ol as representative binary off-odor compounds related to oyster enzymatic hydrolysate. Although 1-octen-3-ol alone has a higher affinity for V-type starch than heptanal, an appropriate proportion of 1-octen-3-ol enhances the encapsulation and loading efficiency of heptanal in the binary system. Compared with the single system, the binary system exhibited lower relative crystallinity and greater enthalpy, suggesting that co-inclusion of the two guest molecules disturbed the long-range crystalline packing while increasing the extent and/or stability of inclusion complex formation. Molecular dynamics simulations suggested that 1-octen-3-ol induced a larger amylose helical cavity and modified the hydrogen-bond network, which may facilitate heptanal accommodation at an appropriate H/O ratio. These findings clarify binary off-odor co-encapsulation by V-type starch and provide a basis for developing starch-based odor-scavenging materials for aquatic foods.","PeriodicalId":318,"journal":{"name":"Food Chemistry","volume":"532 Pt 2","pages":"151573"},"PeriodicalIF":10.4,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149223008","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}

PNLA performed best: it maintained texture, minimized cooking loss, and inhibited spoilage. Lipidomics revealed that PNLA was associated with relative preservation of certain phosphatidylethanolamine species and a distinct glycerophospholipid remodeling pattern, whereas other treatments were linked to increased phospholipase markers and phosphatidylcholine oxidation. These associations suggest a potential protective effect on membrane lipids; however, direct measurements were not performed. Thus the proposed mechanisms remain correlational and hypothesis-generating. Although reactive species were not quantitatively measured, PNLA's distinct profile was hypothesized to enable multi-target preservation by reducing lipid oxidation, microbial spoilage, and structural degradation.

Herein, we presented a strategy for finely tuning the encapsulation and release profiles of fragrant molecules through engineering the pore surface properties of covalent organic frameworks (COFs). Three imine-based COFs with variable functional groups (TAPB-DHTP-COF, TAPB-DMTP-COF, and TAPB-DVA-COF) were rationally designed and constructed via solvent evaporation method, which exhibited stable crystallinity, uniform morphology, and tunable surface areas (152-1056 m2 g-1), and pore sizes (2.3-3.9 nm). Notably, the polar COFs demonstrated significantly higher loading capacities for polar aldehyde-type fragrances (anisaldehyde, Ani; and citral, Cit) compared to nonpolar terpene-type (limonene, Lim). Density functional theory (DFT) calculations revealed that the superior adsorption of polar fragrances into the COFs was governed by strong hydrogen bond interactions, with adsorption energies of -1.16 eV (Ani) and -1.17 eV (Cit) versus -0.37 eV (Lim). All fragrance-loaded COFs exhibited sustained release profiles over 48 h, in stark contrast to the rapid release of free fragrances. Importantly, the release rate was tunable by modulating host-guest interactions, stronger hydrogen bonding led to more prolonged release. This pioneering research established COFs as a heavy metal-free, designable platform for the encapsulation and controllable release of volatile fragrances, showcasing promising applications in cosmetics and personal care industries.","PeriodicalId":318,"journal":{"name":"Food Chemistry","volume":"532 Pt 1","pages":"151504"},"PeriodicalIF":10.4,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149178491","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}
