METHOD FOR PRODUCING A MILK-BASED PRODUCT WITH REDUCED PLASMIN-ACTIVITY

摘要

The present invention relates to a method of inactivation of plasmin enzyme in a milk-based product, wherein casein and whey protein are separated from a milk raw material by microfiltration to provide a casein concentrate as a microfiltration retentate having a whey protein content of less than 20 wt.%, based on the total protein content of the concentrate, and a whey protein concentrate as a microfiltration permeate; the casein concentrate is subjected to a thermal treatment at a temperature in the range of about 72°C to about 95°C to provide a thermally treated casein concentrate; and a milk-based product with a reduced plasmin activity comprising the thermally treated casein concentrate is provided. The milk-based products prepared by the method retain flawless organoleptic properties at different storage temperatures even under prolonged storage periods.
