DBP extraction was carried out using maceration (control) and three levels of ultrasound power (256, 448, and 640 W) for 5, 15, and 25 min. Ultrasound-assisted extraction (UAE) of DPB resulted in a 40% higher yield than macerated samples (9.35%). Specifically, UAE Sample C (256 W, 25 min) significantly improved the total monomeric anthocyanin content (by 33%), total phenolic content (up to 16%), and radical scavenging activity (by 26%) compared to the control. The morphology of the ultrasound-treated DBP showed porous cells that resembled a hollow honeycomb structure. The phenolic profiling of ultrasound-treated DBP showed significantly higher contents of anthocyanin, hydroxycinnamic acid, and flavonols than the control. Ultrasound can also extract compounds such as myricetin and quercetin, which typically require strong acids and high temperatures, thus proving that ultrasound is a better extraction method than conventional extraction.","PeriodicalId":72048,"journal":{"name":"ACS food science & technology","volume":"4 11","pages":"2645–2654 2645–2654"},"PeriodicalIF":2.6,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142641061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Samples of Khaki, Cherry, Italian, and Long-Life tomatoes were collected and had their phenolic acid and amino acid profiles determined by HPLC-PDA and HPLC-FL, respectively. Enzymatic activities of peroxidase (PO), polyphenoloxidase (PPO), catalase (CAT), and phenylalanine ammonia lyase (PAL) were also determined. OTA levels were below the quantification limit (2.2 ng g–1) in every sample. Their dissimilarity was determined by the CA of the defense mechanism components. The tomato varieties were classified into three subgroups: Italian, Khaki, and Long-Life and Cherry. They had similar soluble phenolic contents whose extracts were inhibited at around 50% growth of P. verrucosum and A. ochraceus. Although they did not have any fungistatic effect, the minimal inhibitory concentration was low (0.2 ng mL–1). Absence of OTA in samples and antifungal activity of phenolic extracts suggested that these tomato varieties had efficient strategies against damage caused by these toxigenic fungal species.","PeriodicalId":72048,"journal":{"name":"ACS food science & technology","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142262686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, five-day fermentation cocoa sweating (FS) was collected, freeze-dried, and incorporated into wheat bread production. The organic acids and sugars found in FS were citric acid (13 g/kg), acetic acid (10.2 g/kg), lactic acid (0.06 g/kg), and sucrose (4.7 g/kg), glucose (5.9 g/kg), and fructose (4.5 g/kg), respectively. Microbiologically, FS contained lactic acid bacteria (LAB; 5.1 log CFU/g), yeast (2.4 log CFU/g), and no coliforms detected. The bread produced with FS (BFS) had water absorption (64.75%), mixing time (3 min), and breadmaking features comparable to those of the control wheat bread (BWF). However, BFS had significantly lower bread volumes. The organic acids found in BFS (citric acid, 200 mg/kg; acetic acid, 670 mg/kg; lactic acid, 3460 mg/kg) were comparable to those in BWF. Despite its browner crumb color, BFS demonstrated superior flavor, aroma, and overall sensory acceptability. Therefore, the FS is a potential ingredient in breadmaking.","PeriodicalId":72048,"journal":{"name":"ACS food science & technology","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142262685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective was to determine the IRI activity of sorghum kafirin hydrolysates as affected by succinylation and the dispersing medium. The IRI activity of the sorghum kafirin hydrolysates was analyzed by the splat assay in phosphate-buffered saline (PBS) and 10 mM NaCl. At 2% concentration, sorghum kafirin hydrolyzed by bromelain for 1 h resulted in 55% reduction in ice crystal size in 10 mM NaCl, while this was not observed when the dispersing medium is PBS. Succinylation at 0.25:1 molar ratio (succinic anhydride: amine group of the peptides) yielded modified hydrolysates that were slightly more IRI active in PBS, but the difference was not significant. The data showed the potential application of sorghum kafirin hydrolysates to act as antifreeze molecules to preserve the quality of frozen materials.","PeriodicalId":72048,"journal":{"name":"ACS food science & technology","volume":"4 9","pages":"2106–2114 2106–2114"},"PeriodicalIF":2.6,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142273744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
