ABSTRACT: The growth rate of two probiotic strains with documented health effects was studied in ultra-high temperature treated milk separately and beside each other. The probiotic strains were Lactobacillus acidophilus (La-5) and Bifidobacterium lactis (Bb-12). Fermentation was followed for 12 h at 37 ˚C and the samples were analyzed for pH, titratable acidity and viable counts of probiotic ba...

To test the hypothesis that amino acid residues in band 3 with titratable positive charges play a role in the binding of anions to the outside-facing transport site, we measured the effects of changing external pH (pH(O)) on the dissociation constant for binding of external iodide to the transport site, K(O)(I). K(O)(I) increased with increasing pH(O), and a significant increase was seen even a...

Two Chinese jujube (Zizyphus jujuba) cultivars ('Huanghua' and 'Zhanhua') at unripe and ripe stages were investigated. During ripening, the weight, pH, hardness, and chewiness of both cultivars decreased while titratable acidity, total soluble solid content, and pectin contents increased. More than 75% pectins of the fruits were water-soluble pectin (WSP). Pectins shared the common major compos...

Tamarind seeds are not consumed despite their high antioxidative activity. In this study, 0-10% tamarind seed powder (TSP) was incorporated into mango juice and cookies. Total phenolics (Folin-Ciocalteu assay), antioxidant activity (2,2-diphenyl-1 picrylhydrazyl (DPPH) radical scavenging assay), flavonoid (aluminum chloride assay), condensed tannins content (Vanillin-HCl assay), and consumer ac...

Eighteen different infants' drinks from five manufacturers were examined for their carbohydrate, calcium, phosphorus and acid contents, and their attack on tooth mineral. Seven of the drinks were compared with nine varieties of adults' soft drinks, and demineralization was studied with and without the presence of a cariogenic oral streptococcus. The influence of the acids already in the drinks ...

Sensory properties and physico-chemical parameters of 10 most popular brands of commercial set-type Turkish yoghurts were evaluated and correlation coefficients between the two indices were investigated. The results indicated that increases in volatile compounds (acetaldehyde, 2-butanone, 2-nanonane, ethyl acetate), titratable acidity, ash and fat contents inversely correlated with the overall ...

Exposure of mango (Mangifera indica cv. Tommy Atkins) fruit to methyl jasmonate (MJ) vapors (10(-)(4) M) for 24 h at 25 degrees C reduced chilling injury during subsequent storage for 21 days at 7 degrees C and after 5 days of shelf life at 20 degrees C. The chilling tolerance induced by MJ was positively correlated with the reduction in the percent ion leakage of mango tissue. The overall qual...

The study assessed the changes in quality and physical chemical parameters of apples four cultivars (‘Gala’, ‘Idared’, ‘Topaz’, ‘Red Prince’) subjected to mechanical vibration during transport under model conditions after storage (shelf-life). Quality were evaluated based on skin flesh colour, total soluble solids, dry matter, firmness, titratable acidity, pH value, polyphenol content, antioxid...
