The general objective of the work is to compare effect addition synthetic citric acid compared natural fruit juice Citrus aurantiifolia on conservation drink based red chalice H. sabdariffa. tests were carried out over a period 5 weeks at 4°C and 37°C with seven batches beverage samples prepared rate calyx/water ratio 1/40 (kg·kg-1) added respectively 1, 2 4 g·L-1 lemon 10, 20 40 mL·L-1. charac...

A simple sequential injection analysis (SIA) with spectrophotometric detection for an assay of acidity in fruit juice was investigated. An alkaline reagent (sodium hydroxide), a sample and an indicator (phenolphthalein) were first aspirated and stacked as adjacent zones in a holding coil. With flow reversal through a reaction coil to the detector, zone penetration occurred, leading to a neutral...

The evidence for a role of sugar-sweetened beverages (SSBs) in the development of obesity and associated comorbid ities, although not fully resolved, is becoming increasingly convincing, with supporting data from both prospective cohort studies and randomised trials. The obesogenic eff ect of SSBs seems to be simply a consequence of the excess calories provided by their consumption, rather than...

BACKGROUND The purpose of this study is to investigate cardiovascular benefits of juices obtained from two commonly consumed fruits in Thailand, Pachyrhizus erosus, L. (yam bean) and Psidium guajava, L. (guava), by examining their acute cardiovascular effects in healthy volunteers. Possible involvements of the dietary nitrate on their effects were investigated as well. METHOD Thirty healthy v...

BACKGROUND Bael (Aegle marmelos (L.) Corr.) has been widely used in indigenous systems of Indian medicine to exploit its medicinal properties including astringent, antidiarrheal, antidysenteric, demulcent, antipyretic, antiulcer, anti-inflammatory and anti cancer activities. The present study aims to evaluate the antioxidative and antiulcer effect of methanolic extract of unripe fruit of Aegle ...

The pectin lyase gene pnl-zj5a from Aspergillus niger ZJ5 was identified and expressed in Pichia pastoris. PNL-ZJ5A was purified by ultrafiltration, anion exchange and gel chromatography. The Km and Vmax values determined using citrus pectin were 0.66 mg ml(-1) and 32.6 μmol min(-1) mg(-1) , respectively. PNL-ZJ5A exhibited optimal activity at 43°C and retained activity over 25-50°C. PNL-ZJ5A w...

Pomegranate (Punica granatum L.) is a native plant, which has many different cultivars in Iran. This plant consists of rich biochemical compounds that plays an important role in human health. This research aims to study some of biochemical compounds of this valuable fruit. Extract of pell and seeds and juice of fruits were prepared. According to the outcomes of this study, the...

During recent years a large annual surplus of grapes has been produced in the United States, and the development of new grape products to take care of this increasing supply is at present an important phase of the grape industry. Because of the general interest in a fruit so abundantly grown, it seemed desirable to study the nutritive value of grapes and grape juices more extensively than had p...

Kiwifruit [Actinidia deliciosa (A. Chev.)C. F. Liang & A. R. Ferguson] is nutritionally rich fruit with high ascorbic acid content (193mg/100g) but the extraction of its juice is difficult due to slimy pulp.To overcome this problem a combination of enzymes (pectinase 0.025g/kg + amylase 0.025g/kg + mash enzyme 0.05g/kg) were used to macerate pulp (2h at 50C) and thus, facilitating the extractio...

BACKGROUND The consumption of fruit is generally associated with better health, but also higher socioeconomic status (SES). Most previous studies evaluating consumption of fruits have not separated 100% fruit juice and whole fruit, which may conceal interesting patterns in consumption. OBJECTIVE To estimate demographic and socioeconomic correlates of whole fruit versus 100% juice consumption ...
