Abstract
The present invention concerns a directly acidified nutritional formula that prevents growth of pathogenic bacteria in the liquid formula even at room temperature for prolonged time. The invention further relates to a method for preparing the formula and to the use of L(+)-lactic acid for preparing nutritional formulas with a pH in the range of 3.5 to 6.
Claims1
A method of preparing a powdered nutritional formula comprising a protein source, a carbohydrate source and a lipid source, wherein the pH of the formula, in its liquid state, is in the range of 3.5 to 6, wherein the formula comprises lactic acid and at least 70% by weight of the lactic acid is present as the enantiomer of L(+)-lactic acid, comprising the steps of:
- hydrating the protein source and the carbohydrate source;
- adding the lipid source;
- adding diluted L(+)-lactic acid to the hydrated carbohydrate source, the hydrated protein source and the lipid source until a pH of about 3.5-6 is obtained, the lactic acid addition taking place in-line;
- and
- drying the obtained mixture.
