International competition within the wine market, consumer demands for newer styles of wines and increasing concerns about the environmental sustainability of wine production are providing new challenges for innovation in wine fermentation. Within the total production chain, the alcoholic fermentation of grape juice by yeasts is a key process where winemakers can creatively engineer wine charac...
Metal ions such as iron can induce DNA damage by inducing reactive oxygen species (ROS) and oxidative stress. Vitamin C is one of the most widely consumed antioxidants worldwide, present in many fruits and vegetables, especially inMalpighia glabra L., popularly known as acerola, native to Brazil. Acerola is considered a functional fruit due to its high antioxidant properties and phenolic conten...
Objective: Due to rich resources of phenolic components such as anthocyanin and flavonoids, grape has grabbed lots of attention. Antioxidants are the frontline of the human immune system against free radicals and they are of high importance for the human health. Methods: In order to determine antioxidant activities, the amount of phenols, anthocyanin and ascorbic acid of 2 grapes’ varieties ("w...
the popularity of non-dairy probiotic products continues to persist as the consumers prefer functional foods satisfying their health needs. among these promising foods, probiotic grape drink would have beneficial effects on modifying gastrointestinal flora and human health. in this study, the pasteurized grape drink was inoculated by three species of lactic acid bacteria (lactobacillus delbruec...
response surface methodology (rsm) was used in order to find the suitable conditions of ultrasonic treatment for achieving the maximum inactivation rate and anthocynins content during ultrasonic processing of red grape juice. temperature in 3 levels (25 - 37.5 - 50°c), time in (20 – 30 - 40 minutes) and frequency (0 - 67.5 – 135 khz) were parameters which effects were studied. experiments were ...
UNLABELLED The disruption of plant cell walls during fruit juice processing results in the enzymatic formation of herbaceous-smelling green leaf volatiles (GLVs). Our objective was to assess the impact of thermal processing conditions on resulting levels of GLVs (hexanal, trans-2-hexenal, hexanol, cis-3-hexenol, and trans-2-hexenol), total phenols, monomeric anthocyanins, and percent polymeric ...
Polyphenols in grape and wine have been suggested to contribute to the cardiovascular health benefits of the Mediterranean lifestyle. The reported effects of grape products on blood pressure (BP) remain, however, equivocal. In a double-blind placebo controlled crossover study, the effect of two grape extracts on BP and vascular function was assessed in 60 untreated, mildly hypertensive subjects...
The grape juice industry has shifted almost entirely from the old method of storing juice in 5-gallon carboys to cool storage in tanks at 22 to 28 F (-5.5 to -2.2 C). Excess tartrates are precipitated during storage. When juice was stored in carboys, the carboys wNere filled at processing temperature, and either spray-cooled or allowed to cool slowly at the cellar storage temperature. For the m...
