ESTIMATION OF PRESERVATION PERIOD AT HIGH TEMERATURE OF MILK BEVERAGE CONTAINED IN CONTAINER

Title:

ESTIMATION OF PRESERVATION PERIOD AT HIGH TEMERATURE OF MILK BEVERAGE CONTAINED IN CONTAINER

Document Type and Number:

Japanese Patent JP2000287656

Kind Code:

A

Abstract:

To provide a method for estimating a preservation period at high temperature of a milk beverage contained in a container sufficiently clearly by a relatively simple procedure, commonly applied to various products, irrespective of types and brands.

This method estimates an unknown preservation period at high temperature of a milk beverage contained in a container by comparing α-casein/β-casein (as milk protein) concentration ratio of the milk beverage with that of a milk beverage of known preservation period at high temperature. The concentration ratio can be determined by converting a dyed extent of electrophoretic pattern of each milk protein into a concentration curve on the densitogram and calculating the α-casein/β-casein peak area ratio from the concentration curves.
