The postharvest treatments included control, low temperatures (14 and 18°C) and plastic bags with or without perforations. Changes in different physico-chemical characteristics of fruits were studied during storage. The two factor experiment was laid out in completely randomized design with three replications of 10 fruits. Among the physico-chemical parameters, colour, firmness, total weight lo...

BACKGROUND Two important quality attributes of processing tomatoes are pH and titratable acidity. These and other quality attributes can be affected by tomato fruit maturity and over-maturity. We have determined the magnitude of these maturity effects in four processing tomato cultivars commonly grown in California. RESULTS Allowing tomatoes to remain on the vine for up to 4 weeks after ripen...

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...

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....

1. Initial glycogen levels in the liver were found to be significantly higher than in the kidneys of the two species studied. The glycogen levels in kidney were however considerably higher than in some mammalian species. 2. Total reducing capacity, true glucose, saccharoid fraction and titratable acidity increase gradually with concomitant decrease in the glycogen levels when liver and kidney h...

This work was carried out during two successive seasons (2009) and (2010) to examine the response of Florida Prince peach fruits to some pre-harvest treatments i.e. chitosan at 0.5 and 1.0% and CaCl2 at 2 and 4 % as well as their combinations on some fruit quality parameters under cold storage . Fruit weight loss (%), decay (%) and T.S.S.(%) of Florida Prince peach fruits were increased in most...
