1. Disaccharidase activities of the small and large intestines of the chick were studied. 2. Homogenates of the small intestine readily hydrolysed maltose, sucrose and palatinose (6-O-alpha-d-glucopyranosyl-d-fructose), hydrolysed lactose slowly and did not hydrolyse trehalose and cellobiose. 3. Within the small intestine the disaccharidases were located mainly in the intestinal wall; the activ...

BACKGROUND Ingestion of a large dose of the milk sugar lactose--for example, the 50 g load in 1 liter of milk--causes symptoms such as abdominal pain, diarrhoea, bloating and flatulence in the majority of people with lactose malabsorption. It is uncertain whether the ingestion of more common doses of lactose, such as the amount in 240 mol (8 oz) of milk, causes symptoms. Some people insist that...

Materials and Methods In the last 5 years (2005-2009) 7-8 patients (9-17 years) diagnosed with severe CMPA were evaluated with SPTs and cow’s milk specific -IgE in vitro determination (casein sIgE levels varied between 126 and 884 KU/L). We performed the SPTs for 17 different special formulae: 1 conventional infant formula (CMF), 3 partially hydrolysed whey/casein ones (pHF-W), 4 extensively hy...

The aim of the study is to be determine effect lactose hydrolysis and sugar content on physicochemical properties, sensory profile HMF (5-hydroxymethylfurfural) in Dulce de Leche (DL). Lactose free (lactose-hydrolysed) dairy products as well low have been developed supply consumer demand. Two different sucrose concentrations, 16% 20%, were used milk jam samples produced by traditional method. F...

Background & Aims of the Study: Because of yoghurt is a particular flavor (caused by diacetyl) and appropriate essential oils (from Atanal) as well as enjoy the soft tissue, it is considered as one of the most palatable dairy products. With regards to the yoghurt portion in supplement of protein food needs in our society, it is necessary to ensure i...

The identity of a novel form of sialyl-lactose found in milk of the echidna (Tachyglossus aculeatus) was investigated. The sialyl-lactose yielded equimolar amounts of N-acetylneuraminic acid and lactose during mild acid hydrolysis but was resistant to the action of a bacterial neuraminidase. A viral neuraminidase hydrolysed it to lactose plus a form of sialic acid that reacted positively with t...

The disaccharide lactose is one of the main components of milk. During the digestion, it is hydrolysed by the enzyme ß-galactosidase into glucose and galactose. With the exception of the Caucasian populations the lactase activity decreases in most people in the age of weaning. After the ingestion of large amounts of lactose, symptoms as bloating, flatulence, abdominal pain and diarrhea can occu...
