The purpose of this study was to analyze polyphenol rich beverages (vitamin enhanced waters (VEWs), fruit juices and berry juices) to determine free polyphenol concentrations and free polyphenols per Calorie based on a serving size. The Folin-Ciocalteu reagent was used in a colorimetric assay based on a catechin standard. Fruit and berry juices contained, on average, more than eight-times the c...

Food is the main source of mineral elements but some are also provided with drinking water and supplements. Juices, for example, are an important source of mineral elements. In infants’ diet minerals are provided mainly by fruit and vegetable purée juices. Infants and young children should be given juices labelled as “special purpose food”. Pasteurised juices are recommended for infants, as the...

In this study, commercial fruit juices present on Romanian market were investigated, by mean of stable isotopes, in order to check their correct labeling. In order to detect the sugar addition, to investigated fruit juices, δC values of: whole juice, pulp and sugars were determined. Beside these, δO and δH values of fruit juices water were measured in order to differentiate directly press juice...

Fruit juice-drug interactions involving drug transporters and metabolic enzymes have been studied with various citrus fruit juices. The collective data led us to hypothesize that the modulating activity of citrus fruit juices on cellular transport and metabolic pathways is dependent on the dominant flavonoid pattern and taxonomy of the citrus fruits. This hypothesis has important implications g...

To evaluate the protective effects of fruit juices against D-galactosamine (GalN)-induced liver injury, lyophilized fruit juices (total 12 kinds) were fed to rats for 7 d, and then we evoked liver injury by injecting GalN. The juice of camu-camu (Myrciaria dubia) significantly suppressed GalN-induced liver injury when the magnitude of liver injury was assessed by plasma alanine aminotransferase...

The demand of fruit juices is increasing day by day as a result of increasing health awareness among the people. Most of juice extraction processes are not producing satisfactory quantity and quality of juices. Enzymatic extraction of juices results in higher yield. The enzymes used are mainly pectinase, cellulase, hemicellase etc. Apart from promoting juice extraction, enzyme addition increase...

The aim of this study was to assess the erosive potential of some soft drinks commonly consumed in Nigeria. A range of popular carbonated drinks (cola and non-cola) and fruit juices were selected. On two occasions, the followings were determined; (1) the pH, measured by a digital pH meter on opening of the packaging can or bottle. (2) The volume of 1.0M sodium hydroxide required to raise the pH...

Fruit and leaf of noni (Morinda citrifolia L.) have been used traditionally as food and for medicinal purposes by South Pacific populations since over two thousand years. Recently noni fruit juice became very popular as health beverage worldwide. Manufacturers and distributors of noni juice often praise the high content of minerals and trace elements in conjunction with the geological situation...

This study was performed to evaluate the nutritional and microbiological quality of industrially processed packed fruit juices of mango (Mangifera indica) and orange (Citrus sinensis) from nine different manufacturing companies in Dhaka City. The highest quantity of total sugar (17.62%) and reducing sugar (9.99%) was recorded in mango juices while the lowest in orange juices (10.41% and 2.24% r...

Four Korean kernel fruit (apple, pear, persimmon, and mandarin orange) juices were obtained by household processing techniques (i.e., blending, juicing). Whole and flesh fractions of each fruit were extracted by a blender or a juicer and then examined for phytochemical content (i.e., organic acids, polyphenol compounds). The antioxidant capacity of each juice was determined by ferric reducing a...
