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...

BACKGROUND Plants produce secondary metabolites that often possess widespread bioactivity, and are then known as phytochemicals. We previously determined that several phytochemical-rich food-derived preparations were active against pathogenic foodborne bacteria. Trichomonads produce disease (trichomoniasis) in humans and in certain animals. Trichomonads are increasingly becoming resistant to co...

Vitis vinifera, known as the grapevine, is native to southern Europe and Western Asia. Grape seed and skin contain several active components including flavonoids, polyphenols, anthocyanins, proanthocyanidins, procyanidines, and the stilbene derivative resveratrol. Grape seed extract in particular has been reported to possess a broad spectrum of pharmacological and therapeutic effects such as an...

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 was carried out to evaluate the effect of heating and physical conditions of grape seeds on the antioxidant activity of their extracts. Two forms of grape seeds, whole and powdered forms, were heated at four different temperatures 50, 100, 150 and 200 C. After heating, grape seeds were extracted with 70% ethanol (0.1 g grape seed/10 mL of 70% ethanol), and total phenol contents (TPC)...

The effects of either cooking temperature (45, 80, and 100 °C) or inclusion of seed particles on the dynamic-mechanical and sensorial properties of value-added Crimson seedless, Black Pearl, or Baresana grape-based smoothies were studied. The inclusion of seed particles resulted in significant increases of the phenolic content, both in Black Pearl and Baresana, but it did not affect in a negati...

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...

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...

Modern medicinal agents currently available for treatment of cancers are very expensive, toxic, and less effective in treating some of the disease. Thus, one must investigate further in detail the agents derived from natural sources, such as grape seed, for the prevention and treatment of cancer and disease. In recent years interest of researchers has focused on grape seed and nowadays scientis...

BACKGROUNDS AND OBJECTIVE Several clinical trials have shown that grape seed extract can reduce blood pressure, but the results are often irreproducible. We therefore sought to systematically evaluate the impact of grape seed extract treatment on the changes of systolic/diastolic blood pressure (SBP/DBP) by meta-analyzing available randomized controlled trials. METHODS Trial selection and dat...
