Abstract

PURPOSE:To carry out preferentially sugar ioversion reaction and to enable the preparation of oligosaccharide in high yield, by feeding a lactose solution having a specific concentration at a specified space velocity to a column packed with a carrier to which beta-galactosidase is immobillized, treating it with the enzyme. CONSTITUTION:Lactose is treated with beta-galactosidase produced by Aspergillus oryzae, to prepare a substance for promoting the propagation of Bifidobacterium, consisting of oligosaccharide as an active ingredient. In this method, beta- galactosidase immobilized on a carrier is used, and the lactose concentration of the lactose solution to be treated is 10-36wt%, and the pH is preferably 3.0- 7.0. The lactose solution is fed at 10-70/hr space velocity to a column packed with the carrier to which beta-galactosidase is immobilized to carry out enzymic treatment. Namely, in the competitive hydrolysis reaction and sugar ionversion reaction in the treatment of lactose with beta-galactosidase, the latter is done preferentially, so that oligosaccharide is obtained in high yield.

The reactions that occur during the enzyme treatment are lactose hydrolysis and sugar transfer by β-galactosidase, and oligosaccharides are produced from lactose by the sugar transfer reaction. Since hydrolysis and sugar rearrangement occur in parallel, β-
When lactose is treated with galactosidase, not only oligosaccharides but also the hydrolysis products glucose and galactose are simultaneously produced. Furthermore, as the enzyme treatment continues, the oligosaccharides produced are gradually hydrolyzed into monosaccharides. give. Therefore, when oligosaccharides are produced by batch enzymatic treatment, there is a processing time at which the yield of oligosaccharides reaches its maximum, and at this point the processing must be discontinued, but the yield of oligosaccharides based on sugars is still 20%. It remains to a certain extent.

In carrying out the treatment, the concentration of lactose in the solution to be treated and the rate of liquid passage are important.

Lactose concentration is 10-36%, preferably 30-3
6%. When the lactose concentration is lower than this, the production rate of monosaccharides by hydrolysis increases and even exceeds the production rate of oligosaccharides, so it cannot be said that it is more advantageous than the batch method in terms of yield. Put it away (experiment example 2 below)
reference). Therefore, a 1 degree centigrade lactose solution such as milk cannot be used as a liquid to be treated in the method of the present invention. On the other hand, when the lactose concentration is higher than the above range, the liquid becomes supersaturated and lactose may precipitate in the liquid pipe.

Although the liquid passing rate varies depending on the r+H and concentration of the liquid to be treated, the space velocity (SV) must be 10 to 70/Hr, preferably 20 to So/Hr. In addition, when s■ is small, the hydrolysis reaction becomes more severe and the production rate of monosaccharides increases, as in the case where the lactose concentration is low (see Experimental Example 1 below). On the other hand, if the SV is too large, the sugar rearrangement rate will not become worse when compared to the hydrolysis rate, but the absolute value of the sugar rearrangement rate will decrease and the yield of oligosaccharides will deteriorate.

Although there are no particular limitations on the treatment conditions other than the lactose concentration and the liquid flow rate, it is desirable that the pH of the liquid to be treated is in the range of 3.0 to 7.0.
