A method for producing a processed milk containing galactooligosaccharide. An animal milk is treated with a .beta.-galactosidase derived from Streptococcus thermophilus or Lactobacillus bulgaricus so as to change, at least 15% of the lactose contained in the animal milk, into galactooligosaccharide expressed by the following general formula:

Method for producing processed milk containing galactooligosaccharide

A method for producing oligosaccharides which are represented by the general formula Gal-(Gal)n-Glc (where Gal is a galactose residue, Glc is a glucose residue, and n is an integer from 1 to 4) which is characterized in that lactose or a lactose-containing substance is treated with at least two kinds of .beta.-galactosidases which are produced by different microorganisms. The present invention provides a method of producing oligosaccharides to obtain sweet saccharide mixture which provide sweetness and add oligosaccharides to food and drinks, with a lower increase in calories than that of conventional additives.

Method for producing oligosaccharides

A liquid food comprising polydextrose and oligosaccharides which are hard to digest and easy to ferment is provided. This liquid food has excellent effect for relieving constipation.

Liquid food for curing constipation: polydextrose and oligosaccharide

This invention relates to a composition for promoting growth of Bifidobacteria containing as effective constituent an oligosaccharide represented by the general formula Gal-(gal).sub.n -Glc, wherein Gal denotes a galactose residue, Glc a glucose residue and n an integer of 1 to 4. This invention further relates to a method for manufacture of the material for promoting growth of Bifidobacteria characterized in that lactose or a lactose-containing material is treated with .beta.-galactosidase produced by Aspergillus oryzae.
