BACKGROUND Grape skin, a rich source of phytochemicals, has been reported to possess remarkable anti-obesity activity. Fatty acid synthase (FAS) is a key enzyme catalyzing the synthesis of fatty acid de novo, and has been considered as an anti-obesity target. To elucidate the anti-obesity mechanism of grape skin, we investigated the effects of grape skin extract (GSE) and resveratrol, one of th...

The objective of this work was to estimate the antioxidant potential of the extracts from pink shrimp residue and red grape pomaces (Merlot and Syrah varietals), evaluated according to its antioxidant activity with different analytical methods, associating these properties with the chemical composition of the extract and, as a consequence, with the extraction procedure. The shrimp residue was p...

The aim of this work was to determine the effect different drying treatments: freeze-drying, room-drying, and oven-drying on grape phenolic composition 'Regent' 'Cabernet Sauvignon' varieties. After drying, samples were grounded, submerged ultrasound-assisted extraction, analyzed with high-performance liquid chromatography (HPLC). This study demonstrated that use methods significantly affects c...

this study was conducted to assess the in vitro organic matter digestibility (omd) of pistachio hull using rumen fluid of taleshi sheep. animals were fed diets composed of 34% pistachio hull, 29% grape pomace, 32% alfalfa, and 5% grain barley. the chemical composition and phenolics' levels of pistachio hull, either industrially dried pistachio hull (idph) or sun dried pistachio hull (sdph)...

Among 60 vining species growing almost exclusively in the Northern hemisphere, only the grapevine (Vitis vinifera L.) (Vitaceae) is the single species largely used in the global wine industry. Grapes are important sources of antioxidants, such as phenolic compounds. The antioxidant activity of these polyphenols is considered much higher than that of the essential vitamins, thus contributing sig...

Abstract Grape pomace, a press residue of winemaking process, has great usage potential in many fields because its phenolic components such as anthocyanins, antioxidants and dietary fiber. In this study, it was aimed to determine most suitable parameters for production food colorant from grape pomace (variety okuzgozu) under different extraction conditions, thus utilising waste wine production....

Grape stems are a by-product of wine production which is managed as waste. Animal feeding arises potential alternative. However, its practical use may be compromised by high lignin content. In this sense, hydrolysis emerges strategy to increase fibre digestibility. addition, due and variable moisture content, it should dried prevent microbial deterioration washing pre-treatment reduce sugar con...
