Temperature integration where high day temperatures are compensated by lower night temperatures is one strategy that can be used to reduce energy consumption in greenhouses. Crop tolerance to temperature variation is a prerequisite for using such a strategy. Greenhouse experiments were conducted on tomatoes cvs, Capricia, Mecano and Cederico in order to investigate the effect of different day/n...

currently, due to their beneficial effects, there is interest in adding prebiotics to food products. thisstudy investigated the effect of the addition of inulin (1% and 2%) on microbial and physico-chemicalproperties of probiotic low fat yogurt manufactured with lactobacillus acidophilus. six experimentalpreparations of yogurt were produced. homogenized, standardized and pasteurized low fat mil...

This research studied the feasibility of making rapid measurements of the soluble solids contents (SSC) and acidity of ‘Fuji’ apple (Malus domestica Borkh. cv. Fuji) fruit. FT-NIR spectra were recorded in the interactance mode, using fiber optics and a special sample holder. Calibration models related the FT-NIR spectra to SSC, titratable acidity (TA) and available acidity (pH) and were develop...

Changes in acidification and starch behaviour were investigated during co-fermentation of cassava and soybean into gari, an African fermented product. Non-volatile acidity, pH and starch content were evaluated using standard analytical methods. Starch breakdown and pasting characteristics were also analysed using a Brabender viscoamylograph. Fermentation caused significant variations in the pH,...

Raw milk for UHT processing at commercial dairy plant was collected from well managed dairy farms. The milk was processed by direct system and heated at 143145oC for 3-5S, then aseptically packed. Three different batches of UHT milk were used in this study. Samples of UHT milk were analysed after processing and during storage at 4, 22 and 37oC ± 2°C for 6 months. The changes in pH, acidity as l...

Kombucha is a fermented tea beverage which is traditionally prepared by fermenting sweetened black or green tea (Camellia sinensis L.) with symbiotic consortium of bacteria and yeasts (SCOBY). In this study, lemon balm (Melissa officinalis L.) was used as the only nitrogen source for kombucha fermentation. During the seven-day fermentation process, pH value, titratable acidity (TA), total pheno...

This study was designed to investigate the relations between gastric acid secretion and alkalinisation of the urine. Normal subjects underwent standard pentagastrin (6 micrograms/kg) (n = 5) and sham feeding (n = 6) tests, with additional collection of urine samples before and two and three hours after the start of the test for measurement of titratable urine acidity. Nine subjects provided uri...

Kalanchoë blossfeldiana Poelln. cv Hikan plants were grown hydroponically with nutrient solution containing 5 millimolar NO(3) (-) (or NH(4) (+)) for 1 to 2 months and then transferred to nutrient solution containing no nitrogen. CO(2) uptake at night, nocturnal increase in titratable acidity, and activity of phosphoenolpyruvate carboxylase increased after the transfer. Thus, transfer to nitrog...
