A liquid chromatographic method for the determination of ochratoxin A in grapes, dried vine fruits, and winery byproducts was developed. A mixture of either acetonitrile/water or acetonitrile/water/methanol was used as an extraction solvent mixture. After immunoaffinity column cleanup, the final extract was analyzed by high-performance liquid chromatography (HPLC) with a fluorometric detector (...

A five level four factors central composite rotatable design under response surface methodology was used to optimize process conditions of the foam mat drying process i.e. egg albumen (0%-12%), methyl cellulose (0.1%-0.5%), drying bed thickness (3-7 mm) and drying temperature (55-75°C) to develop grape bar with final moisture content of 14%±1% (dry-base). Contour and response graphs were genera...

As grape seed is the waste material in processing, these generally utilized as cattle feed many countries, while has been shown to contain high amount of antioxidant compounds and a good source polyphenols wide variety proanthocyanidins. For current study, seeds were collected, dried powdered separately incorporated different noodles such tomato, mint beetroot at 10%, 20% 30% levels. Among thre...

The grape (Vitis vinifera L.) posses several remedy effects. In this study, the anti limnatis nilotica effect of methanolic extract of Vitis vinifera L. plant as well as niclosamide were investigated by anti-leech assay. Distilled water selected as placebo. The mean death time of leeches in groups treated with niclozomide for mature and immature form were 15.4 and 10.1 minutes, respectively. Th...

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 ...

This study performed physical, chemical, and microbiological analyses to determine the best formulation shelf life of a new additive-free Mediterranean diet product. The spreadable creamed product was formulated with roasted peanut (32%) hazelnut mixed, sweetened dried grape (15%) sun-dried apricot (15%). Different storage temperatures as 25 oC, 35 45 oC were used for prediction accelerated she...

Grapes and grape-derived products have worldwide importance due to its consumption by human, however, they may also be used for ruminant feeding when their price or quality is low. The objectives of current study were to determine the nutritive value, in terms of chemical composition, in vitro rumen gas production kinetics and predicted nutrient supply, Fourier Transform Infrared Spectroscopic ...
