The Manufacture of Lactose

چکیده
Industry throughout the world is faced with a common problem that of the disposal of waste materials from manufacturing processes. In the case of the dairy industry, one such 'waste' which is produced in enormous quantities is the whey resulting from cheese and casein manufacture. In the 1996/97 season alone it is estimated that around five billion litres of whey were produced in New Zealand. In New Zealand, much of this whey is used in ethanol production, for recombination into baby milk powders and for whey powder production, but there remains an excess. Whey proteins, mineral salts and other residual components of this complex mixture are readily extracted, but there is still a major component present: lactose.

Sources of β-galactosidase and its applications in food industry
The enzyme β-galactosidases have been isolated from various sources such as bacteria, fungi, yeast, vegetables, and recombinant sources. This enzyme holds importance due to its wide applications in food industries to manufacture lactose-hydrolyzed products for lactose-intolerant people and the formation of glycosylated products. Absorption of undigested lactose in small intestine requires the a...
متن کامل"Added lactose" and "added sucrose" cow's milk formulae in nutrition of low birthweight babies.
During the manufacture of dried milks for infant feeding the composition of cow's milk may be modified by the addition of extra carbohydrate powder to lower the relative proportions of protein and minerals, and in practice various carbohydrates are used in a largely empirical manner. In other circumstances it is known that the quality of dietary carbohydrate affects intestinal tolerance, deposi...
متن کاملNew insights about phenotypic heterogeneity within Propionibacterium freudenreichii argue against its division into subspecies
Propionibacterium freudenreichii is widely used in Swiss-type cheese manufacture, where it contributes to flavour and eye development. It is currently divided into two subspecies, according to the phenotype for lactose fermentation and nitrate reduction (lac+/nit- and lac-/nit+ for P. freudenreichii subsp. shermanii and subsp. freudenreichii, respectively). However, the existence of unclassifia...
متن کاملImpact of enzymatic hydrolyzed lactose on fermentation and growth of probiotic bacteria in whey
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...
متن کاملEvolution of chemico-physical characteristics during manufacture and ripening of Castelmagno PDO cheese in wintertime.
Biochemical, volatile and textural profiles during manufacture and ripening were determined in samples of Castelmagno PDO cheese obtained from three different batches in the main artisan cheese plant of Castelmagno PDO production area. At the end of manufacture, samples were characterised by a pH of 6.57% and 52.4% moisture content. The HPLC analysis of organic acids and sugars showed the exhau...
