Ensilage and bioconversion of grape pomace into fuel ethanol.
Two types of grape pomace were ensiled with eight strains of lactic acid bacteria (LAB). Both fresh grape pomace (FrGP) and fermented grape pomace (FeGP) were preserved through alcoholic fermentation but not malolactic conversion. Water leaching prior to storage was used to reduce water-soluble carbohydrates and ethanol from FrGP and FeGP, respectively, to increase malolactic conversion. Leache...
متن کاملMeat Quality and Storage Characteristics of Pork Loin Marinated in Grape Pomace
This study investigated the meat quality and storage characteristics of pork loin marinated in grape pomace powder during different storage periods. The experimental design included six treatments : pork loin containing only 100% water (Control, C); pork loin containing a combination of 20% grape pomace and 80% water (T1); pork loin containing a combination of 40% grape pomace and 60% water (T2...
متن کاملEffect of the Drying Process on the Intensification of Phenolic Compounds Recovery from Grape Pomace Using Accelerated Solvent Extraction
In light of their environmental and economic interests, food byproducts have been increasingly exploited and valorized for their richness in dietary fibers and antioxidants. Phenolic compounds are antioxidant bioactive molecules highly present in grape byproducts. Herein, the accelerated solvent extraction (ASE) of phenolic compounds from wet and dried grape pomace, at 45 °C, was conducted and ...
متن کاملAntioxidant rich grape pomace extract suppresses postprandial hyperglycemia in diabetic mice by specifically inhibiting alpha-glucosidase
BACKGROUND Postprandial hyperglycemia is an early defect of type 2 diabetes and one of primary anti-diabetic targets. Treatment of postprandial hyperglycemia can be achieved by inhibiting intestinal α-glucosidase, the key enzyme for oligosaccharide digestion and further glucose absorption. Grape pomace is winemaking byproduct rich in bioactive food compounds such as phenolic antioxidants. This ...
متن کاملProcyanidin content of grape seed and pomace, and total anthocyanin content of grape pomace as affected by extrusion processing.
UNLABELLED Grape juice processing by-products, grape seed and pomace are a rich source of procyanidins, compounds that may afford protection against chronic disease. This study was undertaken to identify optimal extrusion conditions to enhance the contents of monomers and dimers at the expense of large molecular weight procyanidin oligomers and polymers in grape seed and pomace. Extrusion varia...
