“…For example, the pH-values of BGlc and BEG are quite similar (6.64 and 6.86, respectively), but the total polyphenols content differs significantly (26.07 and 8.72 mg g dw −1 of pomace, respectively). The same effect was observed for DES’ polarity influence on the polyphenols’ yield [ 30 , 31 ]. Moreover, according to the website of Merck, Germany (20 June 2021), the estimated price of BGlc is close to the organic solvents currently used in the industry (70.22 € kg −1 ) and is therefore suitable for application.…”

The aim of this work is to develop an industrially suitable process for the sustainable waste disposal in wine production. The proposed process involves the development of an environmentally friendly method for the isolation of biologically active compounds from Graševina grape pomace according to the green extraction principles, in order to obtain a ready-to-use extract. In this process, deep eutectic solvents (DES) were used as extraction solvents. Aiming to save time in selecting the optimal DES that would provide the most efficient Graševina pomace polyphenols extraction, the user-friendly software COSMOtherm was used and 45 DES were screened. Moreover, the prepared extracts were chemically and biologically characterized to confirm their safety for human application. Computational and experimental results proved the applicability of COSMOtherm in the selection of the optimal DES for the environmentally friendly preparation of the ready-to-use extract from Graševina grape pomace with expected application in the cosmetic industry.

“…In this context, natural deep eutectic solvents (NADES) stand out as they are formulated by a mixture of two or more natural components, such as non-toxic quaternary ammonium salts and uncharged hydrogen-bond donors, that interact through intramolecular hydrogen bonds. NADES offer different advantages, including low cost, easy preparation from readily available materials, negligible volatility, and low toxicity [78].…”

Identification and Recovery of Valuable Bioactive Compounds from Potato Peels: A Comprehensive Review

2021

View full text Add to dashboard Cite

Nowadays, the potato is one of the most cultivated and consumed food crops in the world and, in recent years, its production has experienced a sharp increase. Its industrial processing generates several by-products that are wasted and cause economic and environmental problems. Among them, potato peel stands out, representing up to 10% of the total potato residues obtained in the processing. On the other hand, these wastes, in addition to presenting antioxidant compounds, are rich in interesting chemical compounds of great value in a biorefinery model. This review summarizes the main compounds present in potato skins as well as the most used and innovative extraction methods employed for their isolation, with special emphasis on the fractions with biological activities. In addition, a sustainable biorefinery proposal focused on obtaining high added-value products with potential applications in the pharmaceutical, food, nutraceutical, or cosmetic industries is included.

“…Two of the selected studies that used citrus peel (orange and lemon) have been included. In the first study, the performance of NADES at 30, 50, or 80% water (v:v) to extract TPC from orange peel was analyzed [3] and the best results were found to be the combinations of NADES 50 and 80% water (5200 and 5100 mg GAE/100 g fresh weight (FW), respectively). The ethanol reference extract obtained 4000 mg GAE/100 g FW, thus, a better performance was observed for the more hydrophilic NADES extracts.…”

“…Orange residues obtained from the orange juice industry are one of the most abundant in the food industry. Seventy million tons of oranges are produced annually worldwide, and the peel comprises 40-50% of the total weight of an orange [3].…”
