We studied the role of duodenal cellular ion transport in epithelial defense mechanisms in response to rapid shifts of luminal pH. We used in vivo microscopy to measure duodenal epithelial cell intracellular pH (pH(i)), mucus gel thickness, blood flow, and HCO secretion in anesthetized rats with or without the Na(+)/H(+) exchange inhibitor 5-(N,N-dimethyl)-amiloride (DMA) or the anion transport...

BACKGROUND Production of fermented probiotic beverages can be a good method for acid whey usage. The obtained products combine a high nutritional value of whey with health benefits claimed for probiotic bacteria. The aim of the study was to define quality properties of beverages based on fresh acid whey and milk with addition of buttermilk powder or sweet whey powder. METHODS Samples were ino...

Twenty-eight apple cultivars were selected for their potential hard cider production in Ontario; juice characteristics measured 2017 and 2018, beginning two years after planting 2015. After being harvested pressed, each sample underwent analyses to determine soluble solids concentration (SSC), titratable acidity (TA), pH, yeast assimilable nitrogen (YAN), polyphenolic concentration. Soluble ran...

The objective of the present work was to evaluate physicochemical and sensory quality juices from different grape cultivars resulting two extraction methods. Juices eight (‘Bordô’, ‘SCS 421 Paulina’, ‘BRS Carmem’, ‘Concord’, Cora’, ‘Isabel’, ‘Isabel Precoce’ Violeta’) were prepared using systems: an integral suquifier; adapted heat exchanger. Physicochemical determinations, such as soluble soli...

this experiment was designed to study the effect of putrescine on quality of table grapes during storage. table grapes cvs, rishbaba and olhoghi were dipped in putrescine solutions (0, 1 and 2mm) by the method of pressure-infiltration. the results indicated that after 55 day of storage putrescine 1 mm in rishbaba and at 2mm in olhoghi cultivars were the most effective treatments in maintaining ...

In the present study, effect of adding pineapple at different rates to sheep yoghurt produced using ABT-2 culture on antioxidant activity, total phenolic compound amount, and 5-hydroxymethylfurfural (HMF) content was investigated. addition, addition storage periods physicochemical analyses (total solids, fat, protein, ash, viscosity, pH, titratable acidity values), growth probiotic cultures (St...

This study was conducted to investigate lactobacillus salivarius subsp. salivarius having probiotic properties to be used as the health adjuncts with fermented milk products. Acidand bile-tolerant lactobacillus salivarius subsp. salivarius was isolated with lactobacilli MRS broth from faeces of 80 healthy persons (infants, children and adults). It was used as a probiotic strain in fermented mil...

The recognition of the importance of the true reaction or hydrogen ion concentration of the blood and body fluids of organisms, as opposed to their titratable acidity, has been responsible in recent years for many important advances in physiology and for a large and rapidly growing body of literature. So great has been the interest in the determination, made possible by the development of the i...
