two probiotic bacteria (lb. acidophilus and b. lactis) were immobilized on the alginate coat of strawberry pieces and were added to the prepared sweet non fat dietary stirred yogurt. physico-chemical parameters namely ph value, titratable acidity and synersis along with the viability of probiotic bacteria of the samples were evaluated over the 8 days of storage at 5 ºc at 2 day intervals. a sig...

photosynthetic characteristics and induction of crassulacean acid metabolism (cam) by drought stress were investigated in sedum album, sedum stoloniferum and rosularia elymaitica from crassulaceae. titratable acidity, malate content, phosphoenolpyruvate carboxylase (pepc) activity and gas exchange parameters were determined in plants at the end and beginning of the photoperiod. results showed t...

OBJECTIVES Evaluate erosive potential of beverages, using exposure times from 3 to 30 min, and to analyse the relationship between erosion and several drink parameters. METHODS pH, calcium, phosphate and fluoride concentration, saturation, titratable-acidity to pH 5.5 and the viscosity of sixteen beverages were measured or calculated. Enamel samples (N = 90) were serially exposed to 1 ml of t...

PURPOSE This study was performed to evaluate the oral health of children with PKU and to assess, in vitro, the erosive potential of 5 amino acid supplements commonly prescribed in the management of these children. METHODS Forty children with phenylketonuria underwent a full dental examination and were compared with an age and sex matched control group. The erosive potential of the supplements...

Studies of taste receptor cells, chorda tympani (CT) neurons, and brainstem neurons show stimulus interactions in the form of inhibition or enhancement of the effectiveness of sucrose when mixed with acids or citrate salts, respectively. To investigate further the effects of acids and the trivalent citrate anion on sucrose responses in hamsters (Mesocricetus auratus), we recorded multifiber CT ...

Roselle calyces are rich in nutrient, but the utilization of its calyces in the preparation of jam is not popular in Africa. The quality attributes of stored Roselle jam from dark and light red varieties were investigated. Roselle jam was processed using the open kettle method. The processed jams were stored at ambient and cold temperatures. At two weeks interval they were evaluated for pH, tit...

In this study the effects of different packaging materials on Tulum cheese made with cloth, stomach, animal skin, pot and plastic materials were investigated. Dry matter, ash, titratable acidity, salt, salt in dry matter, fat, total protein, water soluble nitrogen (WSN), trichloroacetic acid soluble nitrogen (TCA-SN), phosphotungstic acid soluble nitrogen (PTA-SN), electrophoretic casein fracti...

The Pereskia are morphologically primitive, leafed members of the Cactaceae. Gas exchange characteristics using a dual isotope porometer to monitor (14)CO(2) and tritiated water uptake, diurnal malic acid fluctuations, phosphoenolpyruvate carboxylase, and malate dehydrogenase activities were examined in two species of the genus Pereskia, Pereskia grandifolia and Pereskia aculeata. Investigation...

The experiment was performed to evaluate the effect of GA3, 2,4-D on fruit growth and fruit quality of wax apple. The experiment consisted of Red A, Monulla, Atu, Red B cultivars. GA3 and 2,4-D were applied at the small bud and petal fall stage. Physiological, biochemical characters of fruit were recoded. The result showed application of GA3, 2,4-D greatly response in increasing fruit set for a...

In present study, spray-dried sourdough was produced using a pilot scale spray dryer and the physico-chemical and microbial characteristics of the obtained sourdough powder were investigated. The application of the spray-dried sourdough at different levels (3%, 6%, 9% and 15%) in breadmaking was also evaluated. Bulk density, wettability and suspensibility of the sourdough powder were 0.6 g/cm(3...
