Study on continuous production of low-lactose milk with immobilized lactase;

The continuous production conditions of low-lactose milk and the usage stability of the immobilized lactase in the filled-bed reactor were researched.

Co-immobilization of lactase and its application in production of low lactose milk

This purpose of this study was to hydrolysis the lactose in milk by immobilizedβ-galactosidase,with a view to solve the problem that the freeβ-galactosidase generate low lactose milk with large quantity of enzyme and high cost besides getting rid of exogenous protein.

10 percent of the emulsifier can effectively prevent the production process of the 5-HMF browning,And composite brown-brown of the effect of industrial research results show that: the best formulation used in low lactose milk processing by dairy factory has significant efficiency to inhibit browning,which can be applied to industrial production.

To promote the production and consumption of milk, it is necessary to produce and popularize low lactose milk.

In this paper we mainly make a reseatch on the processing technology method and ingredient about the low lactose nutrition milk tablets.

Production of low-lactose milk containing galactooligosaccharides was studied withβ-Galactosidase by transgalactosylation activity from Enterobacter sp.

The molecular structure,origin,physiological functions and the states of application in infant food industry of both fructooligosaccharides and galactooligosaccharides are reviewed.

The conditions for transgalactosylation activity were optimized,and the large yield of galactooligosaccharides with various kind of oligosaccharides was obtained by using 20% lactose as a substrate at pH 5.
