Abstract Background and objectives: The presence of pathogenic bacteria and the factors causing food spoilage are the great challenge for public health. Attention to natural additives instead of chemical preservatives resulted in conducting several studies on plant essential oil and extracts. We aimed at evaluating the antibacterial effect of carboxymethyl cellulose coating enriched by Zataria...
Revalorization of the winery industry residue, grape seed is studied for the production of an oil and defatted meal with nutraceutical properties. Conventional grape seed oil extraction process is carried out by pressing at high temperature affecting the product quality. Oil extraction by cold pressing improves product quality, but it gives a low oil yield. Oil extracted is increased at the pre...
Phenolic compound profiles were investigated by HPLC-MS in two consecutive years to assess genotypic variation in berry skins of nine red Vitis vinifera cultivars. The results showed that the types and levels of phenolic compounds greatly varied with cultivar. Common wine grape cultivars such as Syrah, Cabernet Sauvignon, Cabernet Gernischt and Merlot contained more types of anthocyanins, flavo...
Grape seed oil is a product resulting from the processing of grape marc. It is ever more appealing for the cosmetic and pharmaceutical industries: the pharmaceutical activities concern its antioxidant properties, due to the large content of unsaturated fatty acids. Grape seed oil could be extracted mechanically by pressing or chemically by means of solvents. Among the latter, supercritical CO2 ...
The aim of current research was to develop a water-in-oil emulsion containing grape seed extract for application in cosmeceuticals. Finally grinded dried grape seeds powder was extracted with hydro alcoholic mixture. Emulsions consisting of different concentrations of cetyl dimethicone (Abile EM90), the nonionic emulsifier, liquid paraffin as oily phase and water as aqueous phase were developed...
OBJECTIVE Four plant extracts possessing molluscicidal and insecticidal efficacy were evaluated under laboratory conditions versus Biomphalaria alexandrina, Lymnea cailliaudi snails, their egg masses and Culex pipiens larvae. These extracts included Grape seed, Eucalyptus, Pomegranate, Verbesina alcoholic extracts, as well as Eucalyptus oil. METHODS Different mortalities in the exposed vector...
Today in the wine industry, oenological tannins are widely used to improve wine quality and prevent oxidation in wine aging. With the development of tannin products, new oenological tannins are developed with many specific functions, such as modifying antioxidant effect, colour stabilization and aroma modifications. The aim of this work is to investigate effects of pre-fermentative addition of ...
BACKGROUND: Autoxidation is an irreversible reaction which occurs with the effect of oxygen in the air, and results in unpleasant taste and smell that are known as the signs of rancidity in oil. OBJECTIVES: In this study, the antioxidant potential of clove, summer savory and tarragon essential oils (EOs) in grape seed oil was evaluated. METHODS: Effects of EOs at different concentrations (0.3, ...
