Prickly pear (Opuntia spp) fruit has received renewed interest since it contains a betalain pigment that has an attractive purple colour for the production of juice. Prickly pear juice was prepared by homogenizing the fruit and treating the pulp with 48 g of pectinase from Aspergillus niger. Titratable acidity was determined by diluting 10 ml prickly pear juice with 90 ml deionized water and ti...

introduction: citrus fruits, which belong to the family of rutaceae are one of the main fruit tree crops grown throughout the world. although sweet orange (citrus sinensis) is the major fruit in this group accounting for about 70% of citrus output.citrus fruits are well – appreciated fortheir refreshing juice and health benefits.the health benefits of citrus fruits are linked to the high amount...

Characterization, pasteurization and storage are essential steps in fruit juice processing. Watermelon, pineapple, mango juices were pasteurized at 80 ± 2 °C held different treatment times (1, 2.5, 5, 10, 15 min). Juice yield, pH, proximate composition, total soluble solids, color, vitamin C, microbial quality, mineral content, enzyme activity (polyphenol oxidase (PPO), peroxidase (POD)), pheno...

Total fruit intake in the United States is ~1 cup equivalent per day, or one-half of the 2010 Dietary Guidelines for Americans recommendation for adults. Two-thirds of the fruit consumed is whole fruit and one-third is 100% juice. The nutritional value of whole fruit, with the exception of fiber and vitamin C, may be retained with appropriate juice production methods and storage conditions. One...

The study was undertaken to envisage the effect of growth regulators on preharvest fruit drop and quality of Kinnow mandrin (Citrus reticulata Blanco). Various concentration of 2, 4-D, GA3 and NAA were applied during the last week of November, 2005 to check the impact of various treatments on preharvest fruit drop, yield and fruit quality. Exogenous application of growth regulators significantl...

Cigarette smoke-induced oxidative stress leads to dyslipidemia and systemic inflammation. Morinda citrifolia (noni) fruit juice has been found previously to have a significant antioxidant activity. One hundred thirty-two adult heavy smokers completed a randomized, double blind, placebo-controlled clinical trial designed to investigate the effect of noni juice on serum cholesterol, triglyceride,...

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...

BACKGROUND Diabetes mellitus has become a worldwide health problem. Whether fruit juice is beneficial in glycemic control is still inconclusive. This study aimed to synthesize evidence from randomized controlled trials on fruit juice in relationship to glucose control and insulin sensitivity. METHODS A strategic literature search of PubMed, EMBASE, and the Cochrane Library (updated to March, ...

BACKGROUND Consumption of fruit and vegetables is associated with improved health and a decreased prevalence of chronic degenerative processes. OBJECTIVES The objectives were to assess the bioavailability of vitamin C from orange juice and its influence on plasma vitamin C and 8-epi-prostaglandin F(2 alpha) (8-epi-PGF(2 alpha)) concentrations in a healthy human population. DESIGN Six men an...

Star fruit juice is a potent in vitro inhibitor of CYP3A; however, few reports are available on the inhibition of CYP3A activities by star fruit juice in vivo. Therefore, in this study, we investigated the CYP3A-mediated star fruit-drug interaction in vivo. The effect of star fruit juice on carbamazepine pharmacokinetics was examined in rats. In comparison with water, the area under the concent...
