Regular fish oil consumption can supply enough omega-3 fatty acids to human metabolism. However, omega-3 fatty acids consist of a high amount of polyunsaturated fatty acids that are prone to oxidation, and hence, the storage, transportation, and processing of fish oil are challenging. Therefore, fish oil needs to be transformed into an easy-to-use and stable formulation. The objective of this study was to load fish oil into hollow solid lipid particles using a particle formation technique based on supercritical carbon dioxide (SC-CO<small><sub>2</sub></small>). Powder formulations of fish oil were obtained using two different natural waxes, namely, candelilla and carnauba wax, at different initial fish oil concentrations (30, 40, and 50% w/w). All particles exhibited a spherical shape with a smooth surface. The melting point of the particles decreased on increasing the initial fish oil concentration. The highest loading efficiency was achieved at 50% w/w, with the initial fish oil concentration for candelilla and carnauba wax particles at 72.9% and 92.5%, respectively. Moreover, accelerated oxidative stability tests for 21 days of storage proved that the SC-CO<small><sub>2</sub></small>-assisted particle formation technique successfully protected fish oil against oxidation and increased the shelf life of fish oil. Loading fish oil into waxes enhanced the bioaccessibility of EPA/DHA fatty acids regardless of the wax type, from 6.1% to 8.5% and 11.2% in CLW and CW particles, respectively. Thus, the findings suggest that SC-CO<small><sub>2</sub></small>-assisted particle formation could be an efficient method for forming more stable fish oil formulations.</p>","PeriodicalId":101198,"journal":{"name":"Sustainable Food Technology","volume":" 2","pages":" 436-444"},"PeriodicalIF":0.0,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/fb/d4fb00345d?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review focuses on the extraction of polyphenols as well as the purification, food industry applications and health effects of punicalagin. Considering polyphenol extraction, solvent extraction is the most commonly used method because it offers the highest total phenolic content; however, it is time consuming and energy intensive. Therefore, advanced methods are used to enhance its extraction efficiency, such as enzyme-assisted solvent extraction, resulting in the highest extraction yield. As for the purification of punicalagin from polyphenols, liquid chromatography is the most widely used method, and the highest purity is achieved with semi-high-pressure liquid chromatography (HPLC). Medium-pressure liquid chromatography (MPLC) and high-speed countercurrent chromatography (HSCCC) have similar effects, but relatively fewer studies have adopted these two methods. Besides, punicalagin has outstanding antioxidant properties and can thus be added to functional foods to extend their shelf life. Moreover, it shows great antibacterial effects on drug-resistant pathogens. Its anti-inflammatory potential is governed by its ability to treat infection and hyperimmune-related disorders.

Watermelon seeds are rich in proteins, fats, vitamins, and minerals, and they also contain bioactive compounds such as phenolic acids, flavonoids, and carotenoids. This review seeks to investigate the proximate composition of watermelon seeds, novel techniques employed in the extraction of bioactive compounds and the various facets of therapeutic applications of these seed bioactivities, such as antioxidant, antimicrobial, antimutagenic, hypoglycaemic and anti-inflammatory properties. The effects of these seeds are assessed based on the pharmacological mechanisms underlying their therapeutic actions.

These include health-enhancing food supplements, cosmetics, and newly developed edible products for human consumption.
