Forty-four normal-weight participants (age: 30 ± 10 y; BMI: 23 ± 2 kg/m²) participated in this double-blind, randomized cross-over trial, consisting of two study visits separated by one week. During each study visit, gastric emptying, subjective appetite, glucose, and C-peptide concentrations were measured at regular time intervals over a 4-h period. After 4 h, <em>ad-libitum</em> energy intake was assessed. Despite no effect of bread type on <em>ad-libitum</em> energy intake at the subsequent meal (p = 0.068), WSB led to lower hunger (p &lt; 0.001), higher fullness (p &lt; 0.001), lower desire to eat (p &lt; 0.001), and lower prospective food consumption (p &lt; 0.001) compared to WYB.

Recent research highlights these by-products as abundant sources of bioactive compounds with promising health-promoting properties. This synthesis of current scientific evidence focuses on the potential of pomelo by-products to support gut health and digestive function, with particular emphasis on metabolic regulation. Key bioactive constituents identified in pomelo by-products include dietary fibers, pectins, flavonoids, and essential oils. These compounds have demonstrated the capacity to modulate gut microbiota composition by selectively promoting beneficial bacterial genera and enhancing short-chain fatty acid production. Additionally, pomelo by-products can inhibit carbohydrate-degrading enzymes such as α-glucosidase and lipid-degrading enzymes like pancreatic lipase, contributing to improved glycemic control and lipid metabolism. Furthermore, bile acid binding by pomelo by-product extracts can influence cholesterol metabolism and lipid absorption. Advanced processing technologies including super-comminution, enzymatic modification, fermentation, and pulsed electric field treatments have been investigated to enhance the release, stability, and bioavailability of these bioactive compounds, thereby improving their functional efficacy in food systems. Processing techniques are critically evaluated, highlighting their potential for sustainable upcycling of pomelo processing waste into high-value functional food ingredients and nutraceuticals. Despite encouraging preclinical evidence supporting the health benefits of pomelo by-products, further well-designed clinical trials are necessary to confirm their efficacy and safety in human populations. Overall, pomelo by-products show potential for development into sustainable and functional food ingredients that support gut health, regulate metabolic processes, and contribute to healthier dietary patterns.</div></div>","PeriodicalId":10939,"journal":{"name":"Current Research in Food Science","volume":"11 ","pages":"Article 101150"},"PeriodicalIF":6.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144695340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
