These peptides have attracted significant interest due to their potential therapeutic benefits in managing cardiovascular diseases and their favorable safety profiles. In this study, tilapia skin protein was hydrolyzed using alcalase to generate a peptide hydrolyzate with antioxidant activity. The hydrolyzate was subsequently fractionated through a series of methods including dialysis, Sephadex G-100 gel filtration, DEAE-Sepharose fast-flow ion-exchange chromatography, and reversed-phase high-performance liquid chromatography (RP-HPLC). RP-HPLC analysis indicated that the purity of the enriched antioxidant peptides reached 92.91%. The primary structure of the peptides was characterized by liquid chromatography – tandem mass spectrometry (LC – MS/MS), while circular dichroism (CD) spectroscopy was employed to elucidate the secondary structure of the major peptide component, designated P1-2. Six peptide segments were identified within P1-2, with the following amino acid sequences: ADQLTDDQISEFK, VFDKDQNGFISAAELR, LTDEEVDEMIR, DTDSEEELKEAFR, EADVDGDGQINYDEFVK, and SLGQNPTEAELQDMINEVDADGNGTIDFPEFLNLMARK. Hydrophobic and aromatic amino acids accounted for 40.14% and 11.32% of the total composition, respectively. Database searching with Mascot software followed by alignment analysis using the NCBI database revealed that P1-2 exhibits 72% sequence similarity to a peptide encoded under the accession gi|194716545|gb|ACF93134.1|.

However, its commercial development is severely hampered by the intrinsic instability of its key odorant, 2-propionyl-3,4,5,6-tetrahydropyridine (2-PTHP). This compound undergoes progressive degradation during storage, resulting in a marked attenuation of the characteristic rice-like aroma. To minimize flavor loss during processing, ultrasonic-assisted extraction (600 W for 15 min for 50°C) was utilized to obtain S. tonkinensis extracts. The volatile profile of the extract was characterized by gas chromatography-mass spectrometry (GC-MS) and odor activity value (OAV) analysis, leading to the identification of 28 key aroma compounds, among which five pyridine derivatives showed exceptionally high OAVs ( >400), confirming their dominant role. Furthermore, nontargeted liquid chromatography-mass spectrometry (LC-MS) analysis demonstrated that 2-PTHP primarily exists in solution as stable dimeric adducts. The efficacy of hydroxypropyl-β-cyclodextrin (HP-β-CD) in preserving the rice-like aroma was then systematically evaluated, and the results demonstrated that the addition of 1% HP-β-CD could enhance the concentration of the key odorant 2-PTHP by up to 20%. This study proposes a novel strategy for stabilizing volatile imine aromas in food systems, underscoring the potential of cyclodextrins as versatile tools for aroma preservation and restoration.","PeriodicalId":14050,"journal":{"name":"International Journal of Food Properties","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147908048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our results indicate that the Z variety was rich in glycerophospholipids, isoflavonoids, morphinans, organic oxides, organic phosphonic acids, purines, and thiadiazines. A total of 427 metabolites were differentially accumulated between Z and B during three stages of processing (S, M, and Z). These metabolites were significantly enriched in ABC transporters, flavonoid biosynthesis, tyrosine metabolism, glutamic acid, linoleic acid metabolism, etc. Epicatechin, phenylacetic acid, (-)-cis-carveol, and neochlorogenic acid had higher levels in Z. Forty-three volatile compounds were differentially accumulated in BvsZ and their accumulation levels were affected by processing. The variety Z had a higher relative percentage of alcohols, and esters. Forty-six of the 75 substances contributed to the tea aroma. ZT had compounds with higher ROAV values such as furan (caramel-like and sweet fruity), 2-pentyl- (green beans, vegetable), heptanal (citrus, fatty, and rancid), and others. In total, 113 unique flavors were associated with substances that accumulated at higher levels in ZT.

This study investigates the phenolic compound profile, antioxidant, and α-glucosidase (αG) inhibition activities of different fractions from seedless chestnut rose fruit. Using HPLC-PDA, fourteen polyphenolic compounds were identified, with gallic acid and epicatechin being the predominant components, particularly in the ethyl acetate fraction (EE). The EE exhibited the strongest antioxidant and αG inhibitory activities, attributed to its rich polyphenol content. The superoxide anion scavenging ability of EE was comparable to that of ascorbic acid, with a half-maximal inhibitory concentration (IC50) of 0.302 ± 0.001 mg/mL, while the IC50 of ascorbic acid was 0.301 ± 0.001 mg/mL. EE also showed the highest αG inhibition, with an IC50-αG of 13.922 ± 0.673 µg/mL and an inhibition rate of 97.41%. Kinetic studies confirmed mixed-type inhibition. These findings suggest that phenolic compounds in EE, including gallic acid, ferulic acid, gallocatechin, epigallocatechin, and rutin, significantly contribute to its antioxidant and αG inhibitory activities, positioning EE a promising candidate for nutraceutical and pharmaceutical applications.","PeriodicalId":14050,"journal":{"name":"International Journal of Food Properties","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.tandfonline.com/doi/pdf/10.1080/10942912.2025.2479040?needAccess=true","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147880302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
