“…Another important problem to be addressed stems from the wine industry, which is developing worldwide [16] representing an important economic activity that was affected by the COVID-19 pandemic [17]. In particular, the problem is that approximately 20 % of the grapes, including the seed, stalk, and skins, are not used in wine production and therefore end up in landfills [18] generating pollution.…”

In most cases, waste from the wine industry is wasted, generating environmental pollution. For this reason, the objective of this research was to prepare soaps from the oil of these seeds for subsequent determination of the antioxidant capacity by the 2,2-Diphenyl-1-picrylhydrazyl (DPPH) assay, and with the residues generated from the extraction of the oil, the adsorbent potential of this residue for an anionic textile dye was evaluated. The results showed that the prepared liquid soap presented an antioxidant capacity corresponding to an IC50 of 3.33%. Higher antioxidant capacity was obtained in the solid soap with an IC50 of 0.075%. After the adsorption study of the anionic green acid dye 25 (AG25) with defatted grape seed residues, it was possible to remove 100% of the color from water contaminated with AG25 at a concentration of 30 mg/L at pH=2, a dosage of 0.5 g/L, and an agitation speed of 300 rpm for 120 minutes. The pseudo second order kinetic model was a better fit for the dye removal process thus evidencing that the adsorption mechanism involved is chemisorption. The results of the FTIR-ATR analysis showed that the original grape residue has OH, C-H, and C=O groups that are characteristic of the presence of oil in the seed, and after oil extraction the intensity of the vibrations of the C=O and C-H groups are reduced because the residue was defatted. After the adsorption of AG25, the C-H vibration became less intense. Finally, the point of zero charge of the grape seed variety Italia was 4.67, so the interaction between adsorbate-adsorbent would correspond to electrostatic attractions. The present study has shown that the grape seed variety Italia is a waste with biorefinery potential as it possesses antioxidant compounds found in soaps, which could economically benefit the wine industries, and at the same time, the degreased waste has a high capacity to remove dyes, being an environmentally friendly alternative that can be considered for the treatment of textile wastewater.

Purpose Given the intensified competitiveness in the wine retail industry, partnering with quality suppliers becomes critical to ensure a steady supply of high-quality products and sustainable business growth. This study aims to explore how wine supplier quality attributes impact wine retail businesses and if such effects differ depending on wine retail types. Design/methodology/approach Data were obtained from wine purchasing managers in Korea. To validate the proposed relationships, structural equation modeling was used. A multigroup analysis was conducted to test distinct roles of on/off-premise wine retail types within this research framework. Findings Results support the significance of supplier quality attributes in shaping the landscape of wine retail businesses. Operational and strategic benefits exhibited a positive effect on both financial performance and suppliers’ relationship satisfaction, thereby improving the intent to continue working with suppliers. This study revealed noteworthy distinctions in the effects of supplier quality attributes on operational and strategic benefits between on-premise and off-premise wine retailers. Research limitations/implications Findings provide valuable insights to wine suppliers and buyers concerning the establishment of a mutually beneficial long-term interdependent relationship. The approach sheds light on the unique dynamics of wine retail types, contributing to a more comprehensive understanding of the distinct roles of supplier quality attributes on on-premise and off-premise retailers. Originality/value This study developed an integrative framework, emphasizing the importance of supplier quality attributes in the wine retail industry. This model offers valuable insights into creating favorable buyer–supplier relationships that result in mutual benefits for both wine retailers and suppliers.
