Two-phase olive mill waste (TPOMW) is presently the major waste produced by the olive mill industry. This waste has potential to be used as substrate for solid state fermentation (SSF) despite of its high concentration of phenolic compounds and low nitrogen content. In this work, it is demonstrated that mixtures of TPOMW with winery wastes support the production of lipase by Aspergillus spp. By...

The aim of the present study was the assessment of the antioxidant effects of polyphenolic extracts derived from the stems of three Greek grape varieties (Moshomayro, Mavrotragano and Mandilaria) in endothelial (EA.hy926) and muscle (C2C12) cells. We also investigated the effects of the polyphenolic composition on the antioxidant effects of the grape stem extracts. For this purpose, the endothe...

Our previous study revealed that aqueous extract of grape pomace obtained from a winemaking process could exert bactericidal action upon photo-irradiation via reactive oxygen species (ROS) formation. In the present study, we focused on chemical composition and prooxidative profile of the extract. Liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) analysis showed that po...

background: this study examined the effect of grape seed proanthocyanidin extract (gspe) on lipid peroxidation content and activity of tissue antioxidant enzymes, including catalase, superoxide dismutase and glutathione peroxidase in diabetic rats. methods: thirty male rats were divided into three groups of 10 rats each: control, diabetic and diabetic groups that received 500 mg/kg gspe for 6 w...

Quantification of red grape tannin and red wine tannin using the methyl cellulose precipitable (MCP) tannin assay and the Adams-Harbertson (A-H) tannin assay were investigated. The study allowed for direct comparison between the repeatability of the assays and for the assessment of other practical considerations such as time efficiency, ease of practice, and throughput, and assessed the relatio...

Objective: This study aimed to evaluate the effect of consuming grape seed extract with moderate-intensity aerobic training on the expression of miR-126 and miR-29 in the cardiac tissue in type 1 diabetic male rats. Materials and Methods: 40 rats with an initial weight range of 160-220 g were divided into five groups: Training + Extract, Training, Extract, Diabetic / Control, and Healthy / Con...

Evaluation of physicochemical properties dried Damavand’s apple slices under the effect grape pomace extract

Background: Allergens are mostly composed of glycoprotein structures. It is believed that glycan-specific antibodies may lead to false-positive reactions in immunoassays. In this study we investigated the glycosylation state of grape allergens as well as the presence of antibodies to cross-reactive carbohydrate determinants (anti-CCDs) in sera from grape-sensitive individuals. Methods: Grape...
