Whey is a green-yellowish fluid that derives from cheese-making and casein manufacture. The compositional quality and properties of whey can differ greatly, which depends on production technology and milk quality used. The main constituents of whey’s dry matter are lactose (46-52 g/L) and whey proteins (6-10 g/L) (Jelen, 2003; Adam et al., 2004; Jeličić et al., 2008). Whey fermentation is initi...
In this work we investigate multistability in the lac operon of Escherichia coli when it is induced by a mixture of lactose and the non-metabolizable thiomethyl galactoside (TMG). In accordance with previously published experimental results and computer simulations, our simulations predict that: (1) when the system is induced by TMG, the system shows a discernible bistable behavior while, (2) w...
Objectives: To determine the prevalence of lactose intolerance in patients with functional dyspepsia and to document the association of changing in duodenal villi in Thai patients with lactose malabsorption by using breath hydrogen excretion test. Patients and Methods: Functional dyspepsia patients who had no history of milk allergy and underwent gastroduodenoscopy. Two mucosal biopsy specimens...
The presence of lactose-fermenting Salmonella strains in clinical case materials presented to microbiology laboratories presents problems in detection and identification. Failure to detect these strains also presents a public health problem. The laboratory methods used in detecting lactose-fermenting Salmonella enterica serotype Typhimurium from six outbreaks of salmonellosis in veal calves are...
BACKGROUND Lactose intolerance is a common complication of diarrhoea in infants with malnutrition and a cause of treatment failure. A combination of nutritional injury and infectious insults in severe protein energy malnutrition reduces the capacity of the intestinal mucosa to produce lactase enzyme necessary for the digestion of lactose. The standard management of severe malnutrition involves ...
The present work was aimed to define and validate farmstead production of lactose-free Pecorino di Osilo cheese, fresh ricotta cheese, and salted and smoked ricotta cheese (Ricotta mustia). The enzymatic activity of the commercial preparation containing lactase (1.1 g/mL), preliminarily tested using a spectrophotometric titration, showed activity equal to 4950±40 neutral lactase unit/g. The amo...
ONE of the most interesting natural transformations in carbohydrate metabolism is that occurring in the active mammary gland during the synthesis of the galactose-containing disaccharide, lactose. Rohmann [1919] was able to obtain some evidence of the synthesis of lactose by the action of an extract of the mammary gland upon added sucrose. This investigator, on what now seems inconclusive evide...
Lactose is available in several crystalline forms, which differ in binding properties. A new method of estimating the fragmentation propensity was applied to investigate the consolidation and compaction behaviour of this excipient for direct compression. Mercury porosimetry was used to demonstrate that crystalline lactose fragments during compaction. Tablet strength was found to be dependent on...
