Abstract
A milk calcium composition which is highly dispersible and tasty can be obtained by adjusting the pH of a permeate containing lactic acid and lactic acid ion, which was obtained by treating whey with a UF membrane or NF membrane, to recover milk calcium as a slurry-like precipitate and then admixing this milk calcium with milk proteins.
Claims4
A method for producing a milk calcium composition which is highly dispersible and tasty, comprising the steps of:
- obtaining a permeate containing lactic acid and lactic acid ion by treating whey with an ultrafiltration (UF) membrane or nanofiltration (NF) membrane;
- adjusting the pH of the permeate to form and recover a slurry-like milk calcium preciptate, wherein the permeate contains lactic acid or lactate in a concentration of 0.02% or higher by weight as lactic acid to suppress formation of a hard apatite structure of milk calcium when forming the slurry-like milk calcium precipitate;
- and
- admixing and homogenizing the recovered slurry-like milk calcium precipitate with milk proteins to obtain a milk calcium composition.
