“…The values for ABTS reported in the present study are similar to those reported by Karacabey et al . and slightly higher than those reported by Gullón et al ., although the DPPH values are higher than those reported in the present study and by Moreira et al . In the present study, TPC was measured by two methods, FC and absorbance reading at 280 nm, expressed as mg of GAE, which was positively correlated with ORAC, ABTS and DPPH values for the same samples, with r ≥ 0.83 (Table ).…”

“…The TAC determined by ABTS and DPPH varied from 108 to 221 μmol TE g −1 DW and from 88 to 188 μmol TE g −1 DW, respectively. Gullón et al . analyzed the TAC of the ethyl acetate extracts from vine shoots liquors by ABTS, with values in the range of 63–178 μmol TE g −1 DW and, for DPPH, values were in the range of 23–42 μmol TE g −1 DW.…”

Bioactive compounds and total antioxidant capacity of cane residues from different grape varieties

et al. 2019

BACKGROUND: Every year, the viticulture activity generates considerable amounts of underused lignocellulosic residues as grape cane, which are generally composted or burned despite their potential value as a source of bioactive compounds. Determination of their phytochemical composition and total antioxidant capacity (TAC) may be a useful way of exploiting different high-added value applications. RESULTS: Twenty-one phenolic compounds (PC) and two carotenoids (Car) were quantified by high performance-liquid chromatography-diode array detection in eight grape varieties from different locations inMendoza, Argentina. The maximum concentrations corresponded to the stilbene -viniferin [10 552 g g −1 dry weight (DW)], followed by the flavanols (+)-catechin (3718 g g −1 DW) and (−)-epicatechin (2486 g g −1 DW). In addition, lutein and -carotene were quantified at levels ranging between 350 and 2400 ng g −1 DW. The TAC of the extracts was assessed by oxygen radical absorbance capacity , 2,20-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid and 1,1-diphenyl-2-picrylhydrazyl assays, with a good correlation between TAC and total PC for each sample (r ≥ 0.82). CONCLUSION: Samples of cv. Malbec, the most representative variety of Argentina's winemaking industry, presented high contents of PC, particularly -viniferin, (+)-catechin and (−)-epicatechin. Quercetin-3-galactoside, OH-tyrosol and Car were reported for the first time in grape canes of the eight varieties. The results add to the existing knowledge related to this inexpensive source of high-value bioactive compounds, which could be used as functional ingredients.

“…As previously mentioned, only two studies reporting the use of UAE probes for the recovery of phenolic compounds from vine-canes were found, being one of them exclusively focused on the stilbenes compounds [13,26]. Delgado-Torre et al [14] compared the efficiency of three environmentally friendly extraction techniques, namely SHLE, MAE and UAE, reporting that SHLE allowed to obtain the highest TPC (650.4 µg/mL).…”

“…Even so, there has been a search for more profitable applications for vine-canes, and several alternatives were already investigated, such as the production of biochars, biofuels, pulp for paper sheets, particle board and lignin [7][8][9][10][11]. Recently, several studies have demonstrated that vine-canes are rich in polyphenols [12][13][14][15][16][17] and could be used as a source of these bioactive compounds. of the obtained extracts were also determined by high performance liquid chromatography with photodiode array detection (HPLC-PDA).…”

Vine-Canes Valorisation: Ultrasound-Assisted Extraction from Lab to Pilot Scale

Wine production generates large amounts of vine-canes, a devalued by-product that could be used for the recovery of bioactive compounds. In this work, two vine-canes varieties, namely Touriga Nacional (TN) and Tinta Roriz (TR), were submitted to different ultrasound-assisted extraction (UAE) conditions. The highest phenolic and flavonoid content was observed for TR extract obtained at lab-scale without an ice bath and pilot-scale after 60 min of extraction (32.6 ± 2.1 and 26.0 ± 1.5 mg gallic acid equivalent/g dry weight (dw) and 9.5 ± 0.6 and 8.3 ± 0.8 mg epicatechin equivalents/g dw, respectively). Further, all extracts demonstrated a high antioxidant activity to scavenge DPPH free radicals with the best value reached by TR at the lab-scale without an ice bath after 30 min and pilot-scale extraction after 60 min (34.2 ± 2.4 and 33.4 ± 2.1 mg trolox equivalents/g dw, respectively). Extracts phenolic composition were also evaluated by HPLC, demonstrating that resveratrol, myricetin and catechin were the main compounds. According to our knowledge, this is the first time that a pilot scale of UAE of phenolic compounds from vine-canes was performed. This paper represents an important step to the use of UAE as an industrial process to recover bioactive compounds.

“…Vine shoots are considered novel biomass agricultural residues and their management under a biorefinery perspective is attracting notice (Nabais et al, 2010;Dávila et al, 2016). Numerous studies are available in the literature focused on the valorization of vine shoots to obtain high added value products, such as activated carbon (Nabais et al, 2010), polyphenols (Gullón et al, 2017), ethanol (Jiménez et al, 2007), lactic acid and/or xylitol (Rivas et al, 2007). However, to the best of our knowledge, the environmental sustainability of these production schemes has not been assessed yet.…”

The use of vine shoots as feedstock in biorefining activities to obtain bioproducts under efficient and optimized conditions could be crucial to make future high added value compounds and processes more sustainable. In this study, five different potential valorization scenarios from vine shoots differing on diverse extraction and delignification steps were assessed from an environmental perspective using the Life Cycle Assessment methodology to identify the most sustainable biorefining route. The main findings from this study reported that an increment on the number of valorization steps involved higher energy and chemical requirements deriving on worse environmental profiles. Scenarios incorporating fermentation of the glucose liquors or organosolv delignification performed the worst profiles. Autohydrolysis, concentration and freeze drying and enzymatic hydrolysis were the main responsible stages of the environmental burdens. Further research should be focused on optimizing chemicals and electricity requirements to develop greener systems.
