Abstract
The present invention concerns a process for the production of a carbohydrate composition from lactose comprising a mixture of 10-50% galactose, 048% glucose, 1-25% fructose, 148% gluconic acid and 0-25% unconverted lactose and non-lactose di- and oligo-saccharides; and compositions produced by the process as well as food and drink containing the compositions.
Claims35
A process comprising the steps:
- (i) hydrolysis of lactose to produce glucose and galactose;
- (ii) partial isomerisation of the glucose to fructose;
- and
- (iii) partial oxidation of the glucose to gluconic acid;
- to produce a composition comprising a mixture of galactose, glucose, fructose, gluconic acid, unconverted lactose and non-lactose di- and oligo-saccharides.
A composition comprising approximately 10-50% galactose, 0-48% glucose, 1-25% fructose, 1-48% gluconic acid and 0-25% unconverted lactose and non-lactose di- and oligo-saccharides as a % of the total carbohydrate present.
A process for the production of galactose comprising the steps:
- (i) hydrolysis of lactose to produce glucose and galactose;
- (ii) partial isomerisation of the glucose to fructose;
- (iii) partial oxidation of the glucose to gluconic acid;
- (iv) crystallization of galactose to produce a mother liquor;
- and
- (v) recovery of galactose crystals from the mother liquor.
