However, their natural bitterness caused by the presence of oleuropein makes them unpalatable in their raw form. Throughout history, various methods have been tried and developed to remove the bitterness of olives. In this study, Gemlik variety black olives underwent a heat pump drying (HPD) process at 40°C for semidrying, followed by different debittering treatments of dry salting and brining, and then samples were stored at 4°C for 5 days. The raw olive sample was found to be the richest in total phenolic content (TPC), oleuropein content, total antioxidant activity (TAA), and total monomeric anthocyanin (TMA) content. The debittering treatments reduced TPC; especially, dry salting led to the highest loss. However, the in vitro gastrointestinal (GI) digestion process increased TPC, indicating that phenolic compounds are still being extracted and released during digestion. DPPH and FRAP values of the predigestion (Ud) samples varied between 102.62 μmol TE/g dw and 224.62 μmol TE/g dw and between 12.67 and 127.96 μmol TE/g dw, respectively. Among the table olives processed using different debittering treatments, the one stored at +4°C exhibited the highest values for TAA and TMA content. All debittering treatments led to reductions in TAA and TMA levels. However, the in vitro small intestinal-digested (Isid) samples showed variations in TAA values, with an increase observed in TAA values for all samples determined by FRAP method. Similarly, TMA values ranged from 12.74 to 30.05 mg/kg in the Ud samples, while TMA values of the samples after in vitro GI digestion ranged from 36.06 mg/kg to 103.28 mg/kg. The treatments used lead to a decrease in oleuropein concentration and an increase in hydroxytyrosol and tyrosol levels. In the evaluation of the fatty acid composition of raw and table olives, 11 different fatty acids including oleic, palmitic, linoleic, stearic, elaidic, palmitoleic, and arachidic were detected in all samples. A total of 57 aroma compounds were detected in the samples, of which 55 were successfully identified. Among the samples, the one subjected to dry salting was the most preferred in terms of sensory evaluation. These findings suggest that when reduced salt consumption is a priority, low-temperature drying process in combination with other debittering treatments can result in olives with an improved flavor and enhanced functionality, providing a healthy black table olive option for consumers.</p>\u0000 </div>","PeriodicalId":15951,"journal":{"name":"Journal of Food Quality","volume":"2025 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/jfq/3738986","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497355","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}

Voluntary and involuntary power cuts on the one hand, and packaging problems on the other, lead to storage problems for these meats, resulting in putrefied meat.

The main objective of this study was to develop sodium alginate-based edible coatings incorporated with gelatin nanoparticles encapsulating pitaya extract (<i>Stenocereus thurberi</i>) using the coaxial electrospray technique. Nine formulations of sodium alginate at 1, 1.5, and 2 (% w/v) were tested with glycerol (1, 1.5, 2% w/v) as a plasticizer. These concentrations were chosen based on previous studies that found similar formulations to provide optimal film-forming properties without affecting color or pH. Rheological tests showed pseudoplastic behavior, typical of polysaccharide-based films. This work is novel in combining sodium alginate with gelatin nanoparticles and pitaya extract, which has been scarcely explored in the literature, improving the functional properties of coatings. Gelatin nanoparticles were obtained with and without pitaya extract, and SEM analysis revealed improvements in morphology, with average diameters of 865 nm. FTIR analysis showed interactions between sodium alginate and nanoparticles via carboxyl, amino, and hydroxyl groups. The coaxial electrospray technique was used to incorporate pitaya extract into gelatin nanoparticles, allowing precise encapsulation and controlled release of bioactive compounds. The physicochemical characterization of solutions with nanoparticles (25% and 30% w/w alginate base) showed significant differences, including decreased luminosity and pH. Zeta potential values ranged from −75.1 to −78.1 mV, indicating strong repulsion between particles, which prevents agglomeration. DPPH and ABTS radical elimination tests revealed a significant increase in antioxidant activity (<i>p</i> &lt; 0.05) in formulations with coaxial nanoparticles. Compared to other formulations in the literature, these coatings exhibited superior antioxidant activity, particularly in radical scavenging. These findings demonstrate that the developed coating is a viable food coating with antioxidant properties, ideal for preserving fatty foods like meat and meat products.
