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 ...

BACKGROUND Recent studies have demonstrated a correlation between perceived stress and oxidative stress. As SOD is the main enzyme of the enzymatic antioxidant defence system of the body, we evaluated the effect of an oral daily intake of a proprietary melon juice concentrate rich in SOD (EXTRAMEL) on the signs and symptoms of stress and fatigue in healthy volunteers. METHODS This randomized,...

The suitability of litchi [Litchi chinensis (Gaertn.) Sonn.] juice concentrate was investigated for the production of litchi wine. The large amount of fermentable sugars (85.20%) and acid content (4.25%) present in litchi juice concentrate were found suitable for its use in wine making. Amongst the four yeast strains screened for alcoholic fermentation of reconstituted litchi juice, Saccharomyc...

BACKGROUND Tart Montmorency cherries have been reported to contain high levels of phytochemicals including melatonin, a molecule critical in regulating the sleep-wake cycle in humans. PURPOSE The aim of our investigation was to ascertain whether ingestion of a tart cherry juice concentrate would increase the urinary melatonin levels in healthy adults and improve sleep quality. METHODS In a ...
