Grape fruits with blue mold symptoms were collected from house storages in different locations in Korea and were investigated for their association with Penicillium species. A total of 12 isolates of Penicillium were isolated from the collected fruits. Based on morphological and cultural characteristics and β-tublin gene sequence data analysis, they were identified as P. bialowiezense, P. citri...

the effects of grape pomace extract (0, 2 and 4%) on quality and shelf life of silver carp ( hypophthalmicthys molitrix ) fillets during chill storage (4°c) were investigated. the control and the treated fillets were analyzed periodically for microbiological (tvc and ptc), chemical (tvb-n), and sensory characteristics. the results showed that grape pomace-treated samples have lower tvb-n (24.2 ...

Objective(s): The aim of this study was to improve different characteristics including antibacterial, antioxidant and physical properties of nanochitosan film by incorporating Mentha spicata essential oil (EO) and methanolic pomegranate peel and grape seed extracts. Methods: The determination of the chemical composition of M. spicata EO was conducted by means of gas chromatography with ma...

Objective: This study was done on 40 male wistar rats to evaluate the curative and protective effect of grape seeds extract on oxidative damage, inflammatory and apoptotic insult on lung tissue induced by cadmium chloride toxicity. Materials and Methods: The rats were classified to control group (group I), cadmium chloride group (group II), grape seeds extract group (group III) and mixture of g...

The crude seed extract of neem, black pepper, mahogani, and garlic bulb with three doses were evaluated against legume pod borer in the country bean field in two seasons kharif 2006 and rabi 2006-2007. The neem seed extract applied @150 and 100 g/l and mahogani seed extract @ 100 g/l of water 7 days intervals on the country bean showed better performance in the reduction of flower and pod damag...

Appearance of a lag period dependent on pH in the expression of the catecholase activity of a polyphenoloxidase extracted in a latent state from Airen grape (Vitis vinifera L.) berries, is revealed, suggesting the hysteretic nature of the enzyme. The lag time was independent of enzyme concentration, indicating that slow pH-induced conformational changes in the protein must occur during assay. R...

the effect of different solvent systems on the extraction of antioxidant and anti radical agents of grape seed was studied. for this purpose 6 different solvent systems with similar polarity and different selectivity were used to prepare grape seed extract. extraction efficiency, reducing activity, radical scavenging property and the effect of each extract on the increase of thermal resistance ...

this study has been done to survey of solvent system effect on extraction of grape seed extract and its antimicrobial properties. for this purpose, grape seed extracts were extracted with six different solvent systems. minimum bactericidal concentration (mbc) of extract on six spoilage and food-born pathogens was determined. the results indicated that mbc of different extracts have no significa...
