INTRODUCTION One of the most frequent parents' concerns is that oral antibiotic formulations induce dental damage in their children's. This study aimed to assess the cariogenic and erosive potentials of 29 pediatric antibiotics. MATERIALS AND METHODS Replicates of each antibiotic were analyzed for the concentration of sugars (sucrose, glucose and fructose) and sorbitol by high performance liq...

A low pH and a high titratable acidity of juices and cola-based beverages are relevant factors that contribute to dental erosion, but the relative importance of these properties to maintain salivary pH at demineralizing levels for long periods of time after drinking is unknown. In this crossover study conducted in vivo, orange juice, a cola-based soft drink, and a 10% sucrose solution (negative...

A polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) technique followed by sequencing of the 16S rDNA fragments eluted from the bands of interest on denaturing gradient gels was used to monitor changes in the bacterial microflora of two commercial kimchi, salted cabbage, and ingredient mix samples during 30 days of fermentation at 4°C and 10°C. Leuconostoc (Lc.) was th...

‘zaferani’ peach, an important native iranian fruit, is a highly perishable fruit of limited shelf life. in the present research, effects of modified atmosphere packaging with three gas combinations (5% co2 + 2% o2, 10% co2 + 2% o2 and air) and two packaging films (polypropylene and low density polyethylene (ldpe)) on physicochemical characteristics and shelf life of 'zaferani' peach ...

the effect of the organic, integrated and conventional methods of kiwifruit cv. 'hayward' production on the fruit quality at its harvest time was investigated. such traits as fruit size, firmness, total soluble solids (tss), titratable acidity (ta), total chlorophyll, total carotenoids, vitamin c, total phenol, flavonoid compounds (catechin, quercetin 3-glucoside and chlorogenic acid)...

The aim of this study was to evaluate and compare potential different optical spectroscopic techniques for quality assessment apple juices. calibration partial least squares (PLS) regression models were developed optimized determination parameters juice non-destructively from the NIR spectra fruit or directly UV-VIS-NIR external validation performed using test sample set. Calibration based on c...

1. In six volunteers, the effect of intragastric administration of different water-soluble chemical isolates of dietary fibre on gastric secretion, acidity and emptying was studied. 2. At 30 min after administration of the test meals, the stomach contents were completely aspirated and the volume, pH, phenol red concentration, total titratable acidity and different electrolytes were measured. 3....

Cactus pear (Opuntia ficus-indica (L.) Mill.) fruit from ‘Orito’ cultivar were stored at 2 °C and 90% RH for 28 days plus three 20 (shelf life, SL). This research analysed the changes in quality parameters (weight loss, firmness, color, titratable acidity, total soluble solids), ethylene production, respiration rate, antioxidant activity bioactive compounds (total phenols carotenoids) of cactus...

Pitanga (Eugenia uniflora L.) is an exotic fruit species of significant economic importance. However, due to genetic variability, its exploitation hampered by the lack homogeneous production. In this scenario, study aimed select pitanga genotypes according physical and physicochemical parameters fruits grown under semi-arid conditions. The was developed at Federal Rural University Semi-Arid Reg...
