Description
Technical field
The present invention relates to dairy products fields, and in particular to a kind of milk protein concentrate product of high thermal stability and its preparation
Method.
Background technique
Milk protein concentrate (Milk protein concentrates, MPC) refers to the cream produced using membrane separating method
Protein content is in 40-85% or product more than 85%.We are properly termed as (embrane method) lactoprotein concentrate, or (film
Method) cream protein concentrate.
The MPC protein quality score protein content in 42-85% etc., MPC having been commercialized is higher, lactose content compared with
It is low, and the ratio of casein and lactalbumin is similar to raw milk, the best original property for maintaining albumen, these characteristics make
Be widely applied in food processing.The characteristics of due to such product high protein Low lactose milk, in dairy products processing usually
For increasing percent protein, but albuminous degeneration can occur in high-temperature sterilization process for higher protein content, to influence albumen
Nutritive peculiarity, and be unfavorable for the processing of product.Have quite a lot of study about improving at present and improve MPC product dissolubility,
Such as using the methods of ion exchange, ultrasonic wave and super-pressure, but it is less about the research for improving product thermal stability.
