In the early nineties the presence of flavonoids in Citrus juices began to attract the attention of a number of researchers, as a result of their biological and physiological importance. This short review will explore two different aspects. The first part will focus on analytical techniques for the characterization of juices from different Citrus fruits regarding their flavonoid content (even i...

The aim of this study was to investigate the effectiveness of ultrasound as a conservation method for the inactivation of Escherichia coli inoculated into cactus pear juices (green and purple). Total soluble solids, pH, titratable acidity, and the kinetics of E. coli in cactus pear juices treated by ultrasound (60%, 70%, 80% and 90% amplitude levels for 1, 3 and 5min) were evaluated over 5 days...

This study investigated the survival of free and microencapsulated probiotic bacteria in orange and apple juices. Eight different strains of probiotic bacteria were used in this study including Lactobacillus rhamnosus, Bifidobacterium longum, L. salivarius, L. plantarum, L. acidophilus, L. paracasei, B. lactis type Bi-04 and B. lactis type Bi-07. The free or microencapsulated probiotic bacteria...

The physicochemical and microbiological qualities of pressurized (500 MPa/30oC/20 min) and pasteurized (90oC/3 min) pennywort juices were determined during chilled storage (4oC) for 4 months. The color parameters and pH values in both processed juices exhibited no changes upon storage. Moreover, it was found that high pressure could preserve various bioactive components including ascorbic acid,...

The juices of grapes (Vitis labrusca L.) are similar to the fruit itself because the main constituents of the fruit are present in the juice. However, their quality characteristics may be modified by the harsh technological processes used for the production of integral food, such as production systems of raw materials and post-harvest treatment of grapes with ultraviolet (UV) irradiation. There...

Analysis of heavy metals was performed in packaged and fresh fruit juices along with powdered drink mixes (Tangs), purchased from different stores Kathmandu Valley, using Flame Atomic Absorption Spectroscopy (FAAS). Selection Fruit Juices Tangs done five fruits, viz., apple, orange, pineapple, pomegranate, mango an attempt to quantify four metals, i.e., Zinc (Zn), Manganese (Mn), Iron (Fe) Lead...

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 present study was aimed at evaluating the antiproliferative potential of anthocyanin-rich fractions (ARFs) obtained from two commercially available juices (blueberry and blackcurrant juices) on three tumor cell lines; B16F10 (murine melanoma), A2780 (ovarian cancer) and HeLa (cervical cancer). Individual anthocyanin determination, identification and quantification were done using HPLC-MS. A...
