Digestion of lactose, the milk disaccharide, makes problem to a large number of the population. Therefore, the lactose intolerant individuals are limited in the intake of milk and dairy products. The lactose – free products offers a solution for the diet. Raman spectroscopic analyses were performed for a purpose of rapid assessment of lactose content in bovine milk, lactose-free milk, mixtures ...

Pure whey protein isolate (WPI)-based cast films are very brittle due to its strong formation of protein cross-linking of disulphide bonding, hydrogen bonding as well as hydrophobic and electrostatic interactions. However, this strong cross-linking is the reason for its final barrier performance. To overcome film brittleness of whey protein layers, plasticisers like glycerol are used. It reduce...

BACKGROUND Both extensively hydrolysed formulas (eHF) and amino acid-based formula (AAFs) have been demonstrated effective for the treatment of CMA. However, in clinical practice, parents complain that hydrolysates are rejected by children due to their bad taste. Flavor of hydrolysed formulas has been poorly investigated although it affects the acceptance of milk over all the other attributes. ...

BACKGROUND Hydrolysed protein diets are used to diagnose and treat dogs with cutaneous adverse food reactions (CAFR). Little is known about what proportion of dogs hypersensitive to the native protein would react to its hydrolysed form. OBJECTIVES To determine the clinical allergenicity of hydrolysed poultry feather (RCU) and chicken liver diets (HZD) in dogs with chicken induced CAFR. METH...

This study aimed to evaluate the effect of Lacticaseibacillus casei 01 as a probiotic culture on production volatile organic compounds and metabolic profile Minas Frescal cheese. Lactose (α-lactose β-lactose), fatty acids (unsaturated saturated), citric acid, tryptophan, benzoic acid were main compounds. Compared with control cheese, cheese was characterized by highest concentration tryptophan ...

Highly purified [D-glucose-1-14C]lactose has been used to study the transport of lactose by Klebsiella sp. strain CT-1. Strain CT-1 transports lactose by a lactose-inducible system that exhibited an apparent Km of 6 mM lactose and an apparent Vmax of 140 nmol/min per mg of cell protein. Lactose uptake was inhibited competitively by o-nitrophenyl-beta-D-galactoside with a Ki value of 8 mM, but w...

Aromatic amines are oxidized in animal tissues to oand p-aminophenols, which are rapidly conjugated to give either sulphates or glucosiduronates. Some of the carcinogenic aromatic amines appear to produce their biological effects after conversion into o-aminophenols. 2-Naphthylamine, for example, which produces bladder cancer, is oxidized to 2-amino-6-naphthol and 2-amino-inaphthol by liver sli...

The classification of the genus Proteus is still to some extent controversial, although recent investigations have clarified the position considerably. The basis of the modern work was the demonstration by Moltke (1927) that 194 Proteus strains all rapidly hydrolysed urea. For the purposes of this paper, the genus Proteus includes all motile, Gramnegative, straight rods which do not ferment lac...

A novel obligately anaerobic, non-spore-forming, rod-shaped, non-motile Gram-reaction-negative bacterium was isolated from infant faeces. The strain, designated NSB1(T), was able to grow on rich media at 30-37 °C, in the presence of up to 2 % (w/v) Oxgall and 2 % (w/v) NaCl. Cells of strain NSB1(T) produced catalase, but not urease and indole. Aesculin was not hydrolysed. The strain was able to...
