Green solvents, like natural deep eutectic solvents (NaDES) derived from biobased molecules, are gaining prominence over conventional due to their eco-friendly, less toxic, biodegradable, and cost-effective attributes. This study focuses on NaDES food-grade compounds for extracting phenolic anthocyanins different rice bran types, comparing them with ethanol 10% acidic water. formulations displayed superior extraction efficiency both in bound free forms. Notably, the betaine/sucrose/water extracted highest antioxidant Niaw Dum Mor variety, showing 7 times higher activity than (2,2)-diphenyl-1-picrylhydrazyl assays 2.5 oil-in-water emulsion systems. highlights effectiveness of betaine-based sucrose compounds, offering a sustainable approach future extract formulations.

This article explores the novel use of natural deep eutectic solvents (NaDES) in real food by incorporating them into mayonnaise, either alone or with pigmented rice bran (RB). Results showed that NaDES-fortified mayonnaises could prevent lipid oxidation. Notably, NaDES2 (betaine:sucrose:water) significantly reduced production hydroperoxides, which was maintained to an average 2.6 mmol LOOH/kg oil, is 2.9 times lower than control (7.5 oil), 7.4 mayonnaise citric acid (19.1 oil). NaDES2-fortified high tocopherols levels (0.97 g/Kg oil) and volatile compounds from secondary effect may result NaDES altering aqueous phase properties notably reducing water activity ∼0.1. Finally, pre-enrichment bioactive molecules (e.g. RB) represents innovative perspective promote health benefits formulated foods.

This study investigates the extraction of phenolic compounds and antioxidant activity from spent coffee ground (SCG) cherry pulp (CCP) using subcritical water combined with high-pressure carbon dioxide (CO₂). The objective was to optimize conditions maximize total content (TPC) DPPH radical scavenging activity. Using Design Expert V.13 Central Composite (CCD), key parameters including time (30–60 min), temperature (180–220 °C), solid-to-water ratio (0.024–0.027 g/mL) were systematically analyzed. optimal for SCG determined be 198 °C, 0.027 g/mL ratio, 60 min, yielding a TPC 217.26 mg GAE/g DW value 23.28 µMol TE/g DW. For CCP, best 189 0.024 54 resulting in 230.13 32.63 results indicate that CCP exhibited higher than SCG, emphasizing its potential valorization. Furthermore, Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) Thin-Layer Chromatography (TLC) analyses confirmed presence bioactive such as quinic acid, theobromine, caffeine. These findings demonstrate effectiveness CO₂ enhancing recovery byproducts. optimized method provides sustainable solvent-free approach extracting high-value compounds, applications functional food, nutraceutical, pharmaceutical industries.
