BACKGROUND In northeastern Brazil, grape pomace has become a potential alternative byproduct because of the recover phenolic compounds from the vinification process. Comparative analyses were performed between lyophilized extract of grape skins from pomace, described as fermented (FGS), and fresh, unfermented (UGS) grape skins to show the relevant brand's composition upon the first maceration i...

Ochratoxin A (OTA) is one of the most important mycotoxins that contaminate a broad range of agricultural and food products. In this study, the occurrence of OTA in available brands of grape juice in Iran purchased from retail outlets or producer were determined for the first time using high-performance liquid chromatography (HPLC) with immunoaffinity columns(IAC) as the clean-up step. The aver...

A growing demand – above all in industrialised countries – for safer foods and cleaner production processes has been observed in recent times. This has led to a drive, by the agro-alimentary industries, for waste reduction and upgrading as a strategy to reduce costs and achieve new sources of income. In fact, waste may be a source of high-added value products potentially useful as beneficial fo...

the popularity of non-dairy probiotic products continues to persist as the consumers prefer functional foods satisfying their health needs. among these promising foods, probiotic grape drink would have beneficial effects on modifying gastrointestinal flora and human health. in this study, the pasteurized grape drink was inoculated by three species of lactic acid bacteria (lactobacillus delbruec...

There are many studies related to the antioxidant activity of grape products; however, they concern only purple and white grape varieties. Up to now, there are no reports of studies on the Goethe rose grape variety, either on its antioxidant activity or on its phenolic and mineral quantification. Thus, the purpose of this study was to evaluate in vitro and in vivo antioxidant activity, as well ...

Wine grape quality and quantity are affected by vine growing conditions during critical phenological stages. Field observations of vine growth stages are too sparse to fully capture the spatial variability of vine conditions. In addition, traditional grape yield prediction methods are time consuming and require large amount grape samples. Remote sensing data provide detailed spatial and tempora...

Letter to Editor: We read with interest the AHA consensus statement “Wine and Your Heart” by Goldberg et al.1 Observational studies suggest an inverse association between the consumption of alcoholic beverages and coronary artery disease. It has been suggested that red wine might be more protective than other alcoholic beverages, although observational studies have wide variations in methodolog...

Copper sulfates (CuSO4) are widely used as the primary component of fungicides in the grape industry. The agricultural-grade CuSO4 that we collected from Chinese nationwide markets were found to be contaminated by polychlorinated dibenzo-p-dioxins and dibenzofurans and high levels of polychlorinated biphenyls (Σ19PCBs: 0.32~9.51 ng/g). In the following research, we studied the impact of CuSO4 a...

Black carrots and black carrot-derived products have gained great popularity in recent years due to their significant content of health-promoting bioactive compounds. Therefore, this study focuses on the production vinegar from carrot juice (BCJ) derived concentrate (BCJC), attain a food product with nutritional added value. In study, effect alcoholic fermentation by Saccharomyces cerevisiae ac...
