“…For HC-mediated extractions, we opted for water (the greenest of solvents) and 70% (v/v) ethanol ( Mahato et al, 2019 ; Viñas-Ospino et al, 2023 ). Dried peel was enclosed in a 50 μm muslin bag and inserted into a 200 mL double-walled Scott bottle fitted with a two-port screw cap ( Supplementary Figure S2A ).…”

“…2.2.1 Solvent-mediated extractions 70% (v/v) ethanol (Biochem Chemopharma, France) was the selected green solvent (as was previously identified as an optimal green solvent for at least total phenolic extraction by maceration (Mahato et al, 2019;Viñas-Ospino et al, 2023)). Drying effectiveness was primarily based on the process's ability to preserve the ethanol-extracted biocomponents and/or to improve their antioxidant activities, relative to fresh peel.…”

Introduction: The endorsement of circular economy, zero-waste, and sustainable development by the EU and UN has promoted non-thermal technologies in agro-food and health industries. While northern European countries rapidly integrate these technologies, their implementation in Mediterranean food-supply chains remains uncertain.Aims: We evaluated the usefulness of hydrodynamic cavitation (HC) for valorizing orange peel waste in the fresh orange juice supply chain of the Maltese Islands.Method: We assessed: a) the effectiveness of HC in extracting bioactive compounds from orange peels (Citrus sinensis) in water (35°C) and 70% (v/v) ethanol (−10°C) over time, compared to conventional maceration, and b) the potato sprouting-suppression and biosorbent potential of the processed peel for copper, nitrate, and nitrite binding.Results: Prolonged HC-assisted extractions in water (high cavitation numbers), damaged and/or oxidized bioactive compounds, with flavonoids and ascorbic acid being more sensitive, whereas cold ethanolic extractions preserved the compounds involved in radical scavenging. HC-processing adequately modified the peel, enabling its use as a potato suppressant and biosorbent for copper, nitrate, and nitrite.Conclusion: Coupling HC-assisted bioactive compound extractions with using leftover peel for potato-sprouting prevention and as biosorbent for water pollutant removal offers a straightforward approach to promoting circular economic practices and sustainable agriculture in Malta.

“…The whiter GM particle was obtained from a higher removal level of impurities. Additionally, ethanol or NADES might dissolve the native carotenoid on the tuber (which served as the color) and remove it during filtration [32,33]. Konjac corm (elephant yam, Amorphophallus rivierii) contained 40 mg total carotenoids per kg fresh corm [34].…”

“…Konjac corm (elephant yam, Amorphophallus rivierii) contained 40 mg total carotenoids per kg fresh corm [34]. Extraction of carotenoids using NADES was possible due to the hydrogen bonding interactions between the solvent and carotenoid [33]. Impaprasert et al [24] reported that the L-value, a-value, b-value, and WI of konjac GM flour were 84,9 0.8, 1.4, and 79.5, respectively.…”

Porang tuber (Amorphophallus muelleri Blume) contains a high amount of glucomannan, an indigestible dietary fiber. Glucomannan is generally isolated using ethanol. To overcome competition with food and feed in the production of bioethanol, it is proposed to use Natural Deep Eutectic Solvents (NADES) for isolating glucomannan. This study evaluated the application of NADES and ethanol to isolate glucomannan from porang flour. The NADES was prepared by mixing betaine and glycerol in different mole ratios. (1:1, 1:2, and 1:3). The result showed that the obtained glucomannan flour ranged from 74.36% to 77.40%. Results indicated that the glucomannan content of glucomannan flour isolated by NADES was lower than that of ethanol. However, glucomannan flour isolated by NADES showed brighter color than that produced by ethanol. The rheological result indicated that the gel of glucomannan flour (1% w/v in water) exhibited pseudoplastic behavior. NADES (betaine and glycerol with a mole ratio of 1:2) was found to be the most effective formula to isolate glucomannan from porang flour compared to the other mole ratios with glucomannan content, viscosity, and whiteness index of 86.78% (dry base), 17,680 cP, and 75.62, respectively.

“…However, most of the extraction processes use organic solvents such as acetone, hexane, ethanol, etc. According to published research, acetone can provide an extraction yield of 7.88 ± 0.59 µg/g dry weight [6], hexane can provide an yield of 113.5 ± 0.4 mg/100 g fresh weight, and ethanol can provide an yield of 110.3 ± 0.3 mg/100 g fresh weight [7]. These solvents pose risks to human health due to their flammability and toxicity, and are harmful to the environment [8].…”

The food industry produces substantial amounts of waste, which can cause a lot of environmental issues. However, such waste is also a valuable source of bioactive substances that can potentially be used either by the food industry or other types of industries, in the production of medicines, nutraceuticals, cosmetics, etc. The present study proposes a novel approach to extract such bioactive compounds from orange peel waste using hydrophobic eutectic solvents synthesized with thymol and fatty acids (hexanoic and octanoic acid). A response surface methodology was employed to optimize the extraction conditions and achieve maximum recovery of carotenoids. The optimal hydrophobic eutectic solvent consisted of thymol and hexanoic acid at a molar ratio of 2:1, and the optimum extraction was achieved using a solvent-to-solid ratio of 12:1 and a temperature of 20 °C for 78 min; this resulted in a recovery of 259.45 μg of total carotenoids per g of dry matter, which is a significantly higher recovery compared to common organic solvents. Based on the above, it is demonstrated that hydrophobic eutectic solvents is a promising solvent that can be used to extract bioactive compounds from orange peel waste.
