AIMS To determine the survival and growth characteristics of Cronobacter species (Enterobacter sakazakii) in infant wheat-based formulas reconstituted with water, milk, grape juice or apple juice during storage. METHODS AND RESULTS Infant wheat-based formulas were reconstituted with water, ultra high temperature milk, pasteurized grape or apple juices. The reconstituted formulas were inoculat...

The search for new treatments against leishmaniasis has increased due to high frequency of drug resistance registered in endemics areas, side effects, and complications caused by coinfection with HIV. Morinda citrifolia Linn., commonly known as Noni, has a rich chemical composition and various therapeutic effects have been described in the literature. Studies have shown the leishmanicidal activ...

The effect of incubation time, incubation temperature, and crude enzyme concentration was observed on the yield, viscosity, and clarity of the juice obtained from bael fruit pulp. The recommended enzymatic treatment conditions from the study were incubation time 475 min, incubation temperature 45°C, and crude enzyme concentration 0.20 mL/25 g bael fruit pulp. The recovery, viscosity, and clarit...

This study investigates the impact of two extraction processes (squeezing whole fruit and centrifuging seeds) pomegranate juice storage on sweet sour quality attributes. The pH, acidity, levels organic acids, sugars anthocyanin differed in both varieties changed during period. Fructose glucose were primary sugars, citric acid was dominant cultivars. A high level established content 15.40, 18.53...

Extracellular tannase and gallic acid were produced optimally under submerged fermentation at 37 (0)C, 72 h, pH 5.0, 10 %(v/v) inoculum and 4 %(w/v) of the agroresidue pomegranate rind (PR) powder by an Aspergillus niger isolate. Tannic acid (1 %) stimulated the enzyme production by 245.9 % while with 0.5 % glucose, increase was marginal. Tannase production was inhibited by gallic acid and nitr...

The binding of vitamin B(12) by human gastric juice has been found to be pH dependent. Maximum binding occurs between pH 6.5 and 10. Outside this pH range the vitamin B(12)-binding ability of human gastric juice decreases and at pH below 2 or above 12.2 this drops sharply to about 10 to 15% of the maximum. Three commercial hog intrinsic factors have been found to give a similar response to pH c...

A interlaboratory study was conducted to evaluate a liquid chromatographic (LC) procedure for the determination of total vitamin C in foods at levels of 5-60 mg/100 g. Emphasis was placed on fruit juices, although selected foods were also included in the study. Following dissolution of sample in water, endogenous dehydroascorbic acid was converted to ascorbic acid by precolumn reduction with di...

The suitability of litchi [Litchi chinensis (Gaertn.) Sonn.] juice concentrate was investigated for the production of litchi wine. The large amount of fermentable sugars (85.20%) and acid content (4.25%) present in litchi juice concentrate were found suitable for its use in wine making. Amongst the four yeast strains screened for alcoholic fermentation of reconstituted litchi juice, Saccharomyc...

Cactus pear (Opuntia ficus-indica) fruit is a berry with a tasty pulp full of seeds that constitutes about 10-15% of the edible pulp. In Mexico, cactus pear is mainly consumed fresh, but also has the potential to be processed in other products such as juice. The objective of this study was to evaluate the effect of different ultrasound conditions at amplitude levels ranging (40% and 60% for 10,...

Red pitaya is a tropical fruit rich in phytonutrients essential for human health. The savored either through its processed products or raw consumption. This study aimed to assess the physicochemical properties of red juice extracted from ultrasonic-pretreated flesh. flesh was cut into cubes and subjected different durations (20, 40, 60 min) ultrasonic treatment. total soluble solids, pH, titrat...
