the objectives of this study were to assess the microbiological quality of egyptian yoghurt and to investigate the antagonistic activity of some probiotic bacteria against some food borne pathogens in vitro and in yoghurt. the results indicated a poor microbiological quality of yoghurt, since the microbiological parameters recorded higher values than the admissible levels. results from the agar...

The purpose of this article is to present possibilities for obtaining a new type probiotic yoghurt enriched by adding hemp press cake flour (HPCF) in different amounts (2%, 4%, 6%, 8% and 10%). Hemp by-product that remains after the cold pressing industrial (Cannabis sativa L.). Principal component analysis showed 4 10% had significant effect, amount 2% HPCF no effect on physicochemical charact...

OBJECTIVE To assess the erosive potential of various soft drinks by measuring initial pH and titratable acidity (TA) and to evaluate enamel surface roughness using different exposure times. MATERIALS AND METHODS The initial pH of the soft drinks (group 1: Coca-Cola; group 2: orange juice; group 3: Cedevita; group 4: Guarana, and group 5: strawberry yoghurt) was measured using a pH meter, and ...

Milk is an important food substance and has a complex polydisperse system. The main components of milk consist lactose, protein, lipids. Mineral substances vitamins are also present in as minor nutrients. Lactose known sugar the only carbohydrate it consists glucose galactose. content lactose varied according to types. Moreover, most energy source during first years human life, providing almost...

A phospholipase C prepared from lymphocytes readily hydrolysed pure phosphatidyl-inositol but was relatively ineffective against phosphatidylinositol in erythrocyte "ghosts" and rat liver microsomal fraction and also against sonicated lipid extracts from these membranes. In contrast, a phospholipase C prepared from Staphylcoccus aureus readily hydrolysed phosphatidylinositol in sonicated lipid ...

Lactose and neuramin lactose were produced by incubating subcellular particles from rat mammary gland in a system containing glucose, uridine diphosphate galactose, and cytidine monophosphate N-acetylneuraminic acid. The K, values for glucose in the synthesis of neuramin lactose were fairly constant for three similarly prepared enzyme preparations (0.25, 0.17, and 0.22 m&r), but were widely dis...

There are a large number of commercially available milk formulae labelled as “hypoallergenic”. However, only a minority of these comply with the criteria established in the guidelines of Subcommittee on Nutrition and Allergic Disease of the American Academy of Pediatrics. As far as the treatment of cow’s milk allergy is concerned, the extensive hydrolysed protein formulae and aminoacid-based fo...

3. Bile and urine samples were hydrolysed by standard methods: metabolites excreted included unconjugated material, glucuronides and substances hydrolysed by cold and hot acid; the major part of the excreted radioactivity was present as substances remaining water-soluble after all forms of hydrolysis. 4. When samples of bile were collected over periods of 1 hr. or less the proportion of radioac...

This work evaluates the effects of dietary inclusion crude or hydrolysed Arthrospira platensis (Cyanobacteria) biomass on growth, muscle composition, digestive functionality and immune activities in gilthead seabream ( Sparus aurata ) fry (20.32 mg mean body weight). A 40-day feeding trial was conducted, aimed at assessing four experimental diets that included 5 10% (w/w) A. , either hydrolysed...
