This study was conducted to explore the possibility of utilization of waste residues (pomace) obtained during carrot juice extraction for the preparation of a value added product viz. carrot based condensed milk product (gazrella, an Indian sweetmeat). The carrot pomace was treated osmotically in two ways: Firstly, dipping in 65°Brix sucrose syrup, secondly, by adding 35% sucrose (dry powder) t...

Grape pomace (GP) is a major byproduct of wine and juice industry, rich in polyphenolics with demonstrated health benefits. Extrusion processing for development of healthy and quality GP supplemented cornstarch snack foods was evaluated using response surface methodology. The retainability of polyphenolic content and antioxidant activity after extrusion processing were further assessed. The pro...

As the major byproduct of winemaking industry, grape pomace remains an untapped source valuable bioactive phenolic compounds. This study elucidated optimal aqueous extraction parameters for maximizing extractability, while avoiding use harsh conventional solvents and limiting water usage, from Cabernet Sauvignon in which red was processed white wine. In single-stage process (AEP), concurrent im...

BACKGROUND/OBJECTIVES We investigated the effects of a combination of grape pomace (Vitis labrusca, Campbell Early) and Omija fruit (Schizandra chinensis, Baillon) ethanol extracts on lipid metabolism and antioxidant defense system in diet-induced obese mice. MATERIALS/METHODS Forty male C57BL/6J mice were divided into four groups and fed high-fat diet (control group, CON) or high-fat diet ad...

The annual production of grape worldwide amounts to almost 70 million tons, and around 80% is used for winemaking. The two major wastes from winemaking process, pomace and lees account for 20 and 7% of the grapes, respectively. They have been expected as a valuable resource to be recycled because they are rich in polyphenols. Polyphenols possess prooxidatve activity as well as antioxidative one...

This study investigated the effects of combined grape pomace and omija fruit extracts (GO) on diabetes-related metabolic changes in type 2 diabetic db/db mice. The effects of GO were compared with those of a resveratrol and schizandrin mixture (RS), which is a mixture of major components of GO. Mice were fed a normal diet with RS (0.005% resveratrol and 0.02% schizandrin in diet, w/w) or GO (0....
