Rainwater samples were collected for the monsoon period of 1988 and 1991–1996 at Dayalbagh (Agra), a suburban site situated in semiarid region. The mean pH was 7.01 ±1.03 well above 5.6, which is the reference pH. Concentration of Ca2+ was observed to be highest followed by Mg2+, NH4 , SO 2− 4 , Cl −, NO3 , Na+, F− and K+. The ratios of SO 2− 4 + NO3 and Ca2+ + Mg2+ (TA/TC) have been considered...

OBJECTIVES The aim of this investigation was to give insights into the impact of carbohydrate-electrolyte drinks on the likely capacity of enamel surface dissolution and the influence of human saliva exposure as a biological protective factor. MATERIALS AND METHODS The pH, titratable acidity (TA) to pH 7.0, and buffer capacity (β) of common beverages ingested by patients under physical activi...

‘In-store’ consumer acceptance tests were performed on a group of 400 American consumers and 250 native Chinese consumers to determine the relationship between ripe soluble solids concentration (SSC) and titratable acidity (TA) on consumer acceptance of ‘Redglobe’ grapes for different ethnic groups. For this, a group of Caucasian, Hispanic and Chinese-American consumers and a group of native Ch...

The aim of the present study was to estimate genetic parameters for calcium (Ca), phosphorus (P) and titratable acidity (TA) in bovine milk predicted by mid-IR spectroscopy (MIRS). Data consisted of 2458 Italian Holstein-Friesian cows sampled once in 220 farms. Information per sample on protein and fat percentage, pH and somatic cell count, as well as test-day milk yield, was also available. (C...

This study aims to determine the effect of fermentation time on microbiological (total lactic acid bacteria), chemistry (pH, total titrated acid) and organoleptic (color, aroma, flavor) qualities product starfruit (Averrhoa carambola L.) probiotic juice drink cultured by L. plantarum B1765. B1765 had been studied has potency as probiotics candidate. The used is 0, 6, 18, 24 hours. Total bacteri...

application of edible coating as a way of prolonging the shelf-life of perishable fruits and vegetables is promising. two plum cultivars (stanley and giant) were treated with 1% chitosan and then stored at 0-1oc and relative humidity of 90±5% for 40 days. changes in weight loss, respiration rate, fruit firmness, soluble solid content, titrable acidity, ph, ascorbic acid as well as decay rate we...

‘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 ...

Kinnow (Citrus nobilis × Citrus deliciosa L.) is a widely grown Citrus species known for its high quality fruit juice with good storage life. The present investigation is concerned with the enhancement of shelf-life of Kinnow fruit juice through refrigeration storage and addition of preservatives. Fruit juice was prepared from fruits harvested at complete physiological maturity and potassium me...
