To enhance probiotic stability, this study explored the microencapsulation of probiotics using complexes formed from resistant starch (RS3) extracted from avocado seeds and okara protein isolate (OPI), which underwent the Maillard reaction. The addition of RS3 altered the secondary structure of OPI and increased its thermal resilience. An optimal ratio of RS3 to OPI was identified. At this ratio, the microcapsules had under 5 % of moisture content which was suitable for long-term storage at 25 °C and 4 °C for up to 8 weeks. This compact structure provided better protection for over 80 % of probiotics at the inlet temperatures and around 99.77 % under simulated gastrointestinal conditions, demonstrating superior characteristics compared to other studies. Additionally, the use of okara protein as a plant-based alternative to animal-derived proteins eliminated allergen concerns, making the encapsulation system suitable for a wider range of consumers. The findings suggested that these naturally derived, biodegradable complexes offered a promising encapsulation material for improving probiotic stability and targeted delivery in functional food and pharmaceutical applications.

This study explores the incorporation of lemon by-products—fresh pomace, flour, and extract—into muffin formulations to enhance their nutritional, antioxidant, and sensory properties while reducing waste. While previous studies have separately explored the use of these lemon by-products, this work uniquely compares all three in a single context. Muffins enriched with lemon by-product flour showed lower lipid (9.97 %) and higher protein content (1.35 %), while those with fresh pomace had the highest fiber levels (6.55 %). Baking significantly increased antioxidant activity and total phenolic content due to the release of bound phenolics and the formation of Maillard reaction products. Sensory analysis revealed that muffins with fresh pomace and extract had the most appealing aroma, whereas those with flour scored lower due to the astringency of citrus peel components. Nonetheless, all formulations achieved high consumer acceptance, with muffins containing fresh pomace offering the best balance between nutritional and sensory qualities. This work highlights the influence of thermal processing on phenolic stability, showing reductions in flavonoids like rutin and naringenin during baking. The findings demonstrate that lemon by-products can be successfully incorporated into baked goods to create functional foods, supporting waste reduction and promoting a circular economy.</div></div>","PeriodicalId":73040,"journal":{"name":"Food chemistry advances","volume":"7 ","pages":"Article 100972"},"PeriodicalIF":0.0,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784007","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}

The antioxidant blend reduced initial burnt notes but also slowed flavor loss and inhibited the development of off-flavors.
