Conteúdo: | In this study, we evaluate industrial grape pomace from two wineries in the region known as São Francisco Valley, in Brazil, which were produced in two different cycles in 2015. The interest in this field of research arises from recent studies that have shown that macro-antioxidant (MACAN) substances have a positive effect on the body, especially because they favor the health of the gastrointestinal tract. Thus, in this research we analyze several varieties of grapes, such as Alicante Bouschet, Egiodola, Tempranillo, Touriga Nacional and Syrah. We quantify the contents of extractable polyphenols, antioxidant activity by the ABTS assay, and non-extractable polyphenols (MACAN). The varieties that showed the highest values regarding the total extractable polyphenols were Alicante Bouschet, 2nd cycle (seed) with 485.79 GAE/100g, and Egiodola 2nd cycle (skin) with 470.74 mg GAE/100g. In the quantification of antioxidant activity by the ABTS assay, the variety Egiodola 2nd cycle (seed) presented 21.06 µM Trolox/100g. The variety that showed the highest MACAN result was Tempranillo 1st cycle (seed) with 613.99 mg/100g. The MACAN compounds available in the analyzed grape pomace presented significant results, due to its high nutritional values that can be incorporated by the food industry in the formulation of new products.
