Energized Dispersive Guided Extraction (EDGE), a New Extractive Approach of Phenolics from Açaí (E. oleracea) Seeds: Chemical Characterization, Antioxidant Properties, and Bioaccessibility of the Extracts
Açai (E. oleracea) is a fruit known for its health benefits. Its industrial processing generates a large volume of seeds, a waste rich in phenolic compounds. In this work, three techniques of extraction were applied to this residue: dynamic maceration (DM), microwave-assisted extraction (MAE), and energized dispersive guided extraction (EDGE); this last one is a novel sample preparation technique. It evaluated the recovery of phenolic compounds in the extractions. The extraction processes were investigated using a central composite design to obtain an extract rich in phenolic compounds, being the EDGE’s extract exhibited the highest phenolic content. With this result, the antioxidant capacity, phenolic profile (HPLC–DAD), and in vitro digestion model were investigated in this extract. The antioxidant capacities found were 6150 µmol Trolox/g (ORAC), 1.39 mmol Trolox/g (DPPH), and 4.45 mmol Eq Fe2 + /g (FRAP). Procyanidin B1 (4.60 mg/g) and B2 (1.05 mg/g) and catechin (1.62 mg/g) were the prominent phenolics. Bioaccessibility ranged from 6.20 to 179.86%; being caftaric acid, quercetin 3-glucoside, and procyanidin B1 bioaccessible in dialyzed fraction. These remarkable results show the EDGE efficiency for recovering bioactive compounds that remain available for intestinal absorption.
期刊介绍:
Food and Bioprocess Technology provides an effective and timely platform for cutting-edge high quality original papers in the engineering and science of all types of food processing technologies, from the original food supply source to the consumer’s dinner table. It aims to be a leading international journal for the multidisciplinary agri-food research community.
The journal focuses especially on experimental or theoretical research findings that have the potential for helping the agri-food industry to improve process efficiency, enhance product quality and, extend shelf-life of fresh and processed agri-food products. The editors present critical reviews on new perspectives to established processes, innovative and emerging technologies, and trends and future research in food and bioproducts processing. The journal also publishes short communications for rapidly disseminating preliminary results, letters to the Editor on recent developments and controversy, and book reviews.
