- ItemA Feasible Approach to Developing Fiber-Enriched Bread Using Pomegranate Peel Powder: Assessing Its Nutritional Composition and Glycemic Index(2023) García, Paula; Bustamante, Andrés; Echeverría González, Francisca Cecilia; Encina, Cristian; Palma, Manuel; Sanhueza, Leyla; Sambra, Verónica; Pando, Maria Elsa; Jiménez, PaulaThe consumption of dietary fiber (DF) has been associated with a reduced incidence of non-communicable diseases. Despite various strategies implemented worldwide to increase DF intake, it remains low. Therefore, the development of new fiber-rich food products that are widely consumed could be a strategy to improve DF intake. In this study, an agro-industrial by-product, pomegranate peel powder (PPP), was used as an innovative source of DF and antioxidant. The objective was to develop a bread enriched with DF, antioxidants, and sensory characteristics by partially replacing wheat flour (WF) with PPP at levels of 0%, 2.5%, 5%, 7.5%, and 10%. Bread with 2.5% and 5% PPP was chosen for a clinical trial to evaluate glycemic response (GR) in healthy subjects and determine the bread’s glycemic index (GI). As the percentage of PPP increased, both the DF and total polyphenol content increased significantly. The highest overall acceptability was achieved with bread containing up to 5% PPP. Consumption of bread with 2.5% and 5.0% PPP significantly reduced the GI compared to the control bread, while the decrease in GR was not significant. PPP could be a potential food and low-cost ingredient to improve the bread’s nutritional quality through its contribution to DF and antioxidants.
- ItemMetabolic Benefits of Phytosterols: Chemical, Nutritional, and Functional Aspects(2023) Jiménez, Paula; Bustamante, Andrés; Francisca Echeverría, Verónica Sambraa, Miguel Ángel Rincón-Cerverac,d, Camila Faríasa, and Rodrigo ValenzuelaPlant sterols encompass phytosterols and phytostanols, with over 250 iden-tified types. They’ve garnered attention in the food industry due to their potential hypocholesterolemic effects. This manuscript offers a current view phytosterols content in foods, their bioaccessibility, bioavailability, and meta-bolic benefits based on existing preclinical and clinical data. Published articles from 2016 to 2023 regarding the effect of sitosterol, sitostanol, campesterol, campestanol, stigmasterol, and mixed phytosterols on preclini-cal models and clinical trials were included. Food and technology-related issues were also discussed. Phytosterols’s bioavailability in food is limited, exhibiting vulnerability to oxidation, low water solubility, and a distinctive taste. Nevertheless, various technological approaches have been devised to enhance its inclusion in food, ensuring adequate doses for harnessing its cholesterol-lowering potential. This effect has been extensively researched, alongside its hypoglycemic and anti-inflammatory properties. There’s a need to create novel functional foods enriched with phytosterols to attain the daily dosage required to leverage its hypercholesterolemic, hypoglycemic, anti- inflammatory, and other ongoing beneficial effects.
