With juices of grapefruit and related fruits, possible relationships between contents of six different furanocoumarins and extents of inhibition of microsomal CYP3A activity have been studied in vitro. Microsomal CYP3A-mediated testosterone 6beta-hydroxylation was inhibited by the addition of a fruit juice (2.5%, v/v) from eight different grapefruit sources, two sweeties, three pomelos, and one...

Recently it has been observed that the lactic acid bacteria are primarily responsible for the production of diacetyl during concentration of orange juice. The amount of diacetyl present is used as an indicator of the degree of contamination, even though it is not a major end product of fermentation. Its presence may be detected even though little change in total acidity or pH has been noted. A ...

BACKGROUND There are both anecdotal clinical and laboratory experimental data suggesting that low pH mouthrinses cause dental erosion. This evidence is particularly relevant to acidified sodium chlorite (ASC) formulations since they have plaque inhibitory properties comparable to chlorhexidine but without the well known local side effects. AIM Studies in situ and in vitro were planned to meas...

One subjective and two objective methods were used to determine the color of reconsti tuted frozen concentrated orange juice. The USDA color scores for 21 samples ranged from 32 to 37 points when this subjective method was used. Two objective methods were used: (a) the Hunter Color and Color Difference Meter to ob tain tristimulus color values and (b) the Bausch and Lomb Spectronic 505 recordin...

Orange juice is one of the most popular juices sold in world. Although very popular, orange market pasteurized, presenting off-flavor compounds and aromas different from freshly squeezed juice. This study investigated how green chemistry, through application glow discharge plasma, can help improve aroma mitigate off-flavors pasteurized was processed at plasma flow rates (10 to 30 mL/min) for 10...

Anthocyanins are natural pigments that could be involved in various health effects. Red oranges are an important dietary source of anthocyanins, including cyanidin 3-glucoside (Cy 3-glc) and an acylated derivative, cyanidin 3-(6''-malonyl)-glucoside (Cy 3-malglc). The aim of this study was to evaluate the absorption and metabolism of red orange anthocyanins in rats fed an anthocyanin-enriched d...

The stability of orange juice obtained from a small extractor and stored in a polyethylene bottle was assessed under isothermal and non-isothermal storage conditions at 4, 8 and 12C for 72 hours. pH, titratable acidity and Brix did not alter significantly during the 72 hours storage. Microbiological analysis showed high initial count for moulds and yeasts that increased in the juice stored for ...

Exercise induced rhabdomyolysis is a complication of long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) and mitochondrial trifunctional protein (TFP) deficiency that frequently leads to exercise avoidance. Dietary therapy for most subjects includes medium-chain triglyceride (MCT) supplementation but analysis of diet records indicates that the majority of patients consume oral MCT only with brea...

OBJECTIVE To evaluate the effect of staining beverages (coffee, orange juice, and red wine) on the Vickers hardness and surface roughness of the base (BL) and enamel (EL) layers of improved artificial teeth (Vivodent and Trilux). MATERIAL AND METHODS Specimens (n=8) were stored in distilled water at 37°C for 24 h and then submitted to the tests. Afterwards, specimens were immersed in one of t...

The main objective of this research was to determine whether a commercial orange juice rich in anthocyanins could have an effect on body weight and on clinical parameters related to obesity including antioxidant status, lipid profile, and metabolic and inflammatory biomarkers. 11 women with an average BMI of 34.4 ± 4.8 kg/m2 were enrolled in a pilot study. Over a period of 12 weeks they receive...
