BACKGROUND Two important quality attributes of processing tomatoes are pH and titratable acidity. These and other quality attributes can be affected by tomato fruit maturity and over-maturity. We have determined the magnitude of these maturity effects in four processing tomato cultivars commonly grown in California. RESULTS Allowing tomatoes to remain on the vine for up to 4 weeks after ripen...

Background/Objective We investigate the effect of antidiabetic Momordica charantia fruit juice on T cells' differentiation, through plasmatic cytokine quantification in type 1 diabetic rats (T1D). Methods Male Wistar rats were rendered diabetic by the injection of five low doses of streptozotocin. Then, animals were treated with Momordica charantia fruit juice for 28 consecutive days. Plasmat...

The aim of the study was to investigate how soft drink and fruit juice consumption in teenagers is associated with life-style, other food choices, eating behaviour and maternal characteristics. A cross-sectional study of 16-year-old girls (n 275) and boys (n 199) and their mothers was undertaken. Questionnaires were used to assess habitual dietary intake, eating behaviour, physical activity, sm...

Grapefruit juice is widely recognized to cause important drug interactions via inhibition of CYP3A4, and a wider variety of fruit juices have been shown to inhibit influx transporters in enterocytes known as organic anion-transporting polypeptides (OATPs). Fruit juice coadministration significantly reduces the oral bioavailability of numerous important medicines relying on this anion transporte...

OBJECTIVE Identifying at what age infants enrolled in public day care centers are introduced to soft drinks and industrialized juice, as well as comparing the nutritional composition of these goods with natural fruit juice. METHODS A cross-sectional study with the mothers of 636 children (aged 0 to 36 months) from nurseries of day care centers, who were asked questions about the age of feedin...

There have been very limited reports on the effects of commercial fruit juices on human CYP3A activity. Therefore, the inhibitory effects of readily available commercial fruit juices on midazolam 1'-hydroxylase activity, a marker of CYP3A, were evaluated in pooled human liver microsomes. The fruit juices investigated were black raspberry, black mulberry, plum, and wild grape. White grapefruit, ...

background: selling unpasteurized fruit juices is common in iran. since health standards are not met in preparation and distribution of these products, food infections may increase. the objective of this study was to assess microbial contamination of handmade fruit juices in gorgan, iran. methods: this cross-sectional study was conducted in the first half of 2009. overall, 100 carrot and cantal...

Pectin rich fruit juices need enzymatic treatment for clarification. As fruits are rich in pectin, pectinolytic treatment can efficiently reduce viscosity resulting in clarified fruit juice. Enzymatic treatment of mango pulp results in 80% recovery of total juice present in the fruit. Use of pectin degrading polygalacturonases increases both fruit juice extraction and clarification. Polygalactu...

This study investigated the effect of added freeze-dried mulberry fruit juice (FDMJ) (1, 3 and 5%) on the antioxidant activity and fermented characteristic of yogurt during refrigerated storage. A decrease in pH of yogurt and increase in acidity was observed during fermentation. The yogurts with FDMJ exhibited faster rate of pH reduction than control. Initial lactic acid bacteria count of yogur...

Xylanase production from Bacillus pumilus VLK-1 in solid state fermentation was enhanced through optimization of the process using one variable approach. The enzyme production was highest (42324±786 IU/g) upon 96h of incubation at 37°C using wheat bran as a substrate moistened with mineral salt solution (pH 9.0) containing 0.1% folic acid, 0.2% riboflavin and 6.0% yeast extract in the ratio of ...
