Rainbow trout were infused continuously for 24 h with epinephrine in order to elevate circulating levels to those measured during periods of acute extracellular acidosis (about 5 X 10(-8) mol l-1). Concomitant effects on branchial solute fluxes were evaluated. Epinephrine infusion caused complex and differential adjustments of Na+ and Cl- unidirectional fluxes (influx and efflux) resulting in a...
background: unlike industrially production, iranian traditional doogh are not pasteurized after production. hence, possible contamination with different pathogenic bacteria may occur during production or post-production of traditional doogh. the aim of the present study was to monitor the behavior of escherichia coli o157:h7 and listeria monocytogenes in traditional iranian doogh at different t...
The relationship between dietary intakes and urinary calcium was examined in a cross-sectional survey of 764 middle-aged and elderly women with markedly different dietary patterns and lifestyles. Urinary calcium was correlated positively with urinary acids, including titratable acid (r = 0.46, P < 0.0001), ammonia (r = 0.42, P < 0.0001), and sulfate (r = 0.52, P < 0.0001). Urinary excretions of...
The lactic acid bacteria (LAB) involved during the spontaneous fermentation of cereals (maize,millet, sorghum) for the production of indigenous foods (‘akamu’, ‘kunu-zaki’) were quantified and identified. The lactic acid bacteria counts varied during the fermentation of the cereals while the titratable acidity (TTA) increased with reduction in pH. Identification of isolates using API 50CHL syst...
Kombucha is a homemade fermented tea that has been traditionally consumed in China for over 2200 years, and is now being used in many other countries. The biochemical basis of the health benefits of kombucha remains largely unknown. The present study was focused on changes in the total antioxidant activity, total phenolic assay and titratable acid content of the kombucha. In addition, the impor...
Introduction: The antimicrobial compounds have attracted attention these days all around the world. Applying essential oils (EOs) as the herbal antimicrobial materials and natural antioxidant are so valuable in the food industry. In this study the effects of Rosmarinus officinalis essential oil (REO) with different phenol contents was investigated on the properties of ...
AIMS The objective of this study was to determine the effect of increasing juice soluble solids above 40 degrees Brix on wine yeast's ability to grow and ferment the juice, with particular focus on acetic acid production, titratable acidity (TA) changes and the maximum amount of sugar consumed by the yeast. METHODS AND RESULTS Riesling Icewine juices at 40, 42, 44 and 46 degrees Brix were ino...
Chitosan in addition to antimicrobial properties is used as an edible coating for improvement storage life of various fruit and vegetables. Weight loss and fungal rot, are the main limiting factors in sweet pepper postharvest life. Therefore in this study the effects of chitosan at concentration of 0.5, 1, 1.5 and 2% were investigated on the quality preservation and fungal rot controlling of sw...
This study investigated the effects of a novel antibacterial film based on chitosan, carboxymethyl cellulose, sodium alginate, tea polyphenols, ascorbic acid, and tangelo peel extract postharvest quality reactive oxygen species metabolism fruit during storage. The composite significantly reduced decay rate weight loss, delayed reduction in total soluble solids titratable acidity, retained firmn...
