A manufacturing method of milk having improved flavor, taste and freshness

PURPOSE: A production method of milk with improved flavor and freshness is provided to prevent the dissolution of offensive taste and odor components into raw milk during a transferring process of the raw milk. CONSTITUTION: A production method of milk with improved flavor and freshness comprises the following: filling a tank lorry with nitrogen gas when transferring raw milk from a farm to the tank lorry; injecting 15-20% of nitrogen gas into the raw milk before degassing the raw milk, and reducing the concentration of dissolved oxygen in the raw milk less than 5ppm; pre-heating the raw milk at 50-60 deg. C before sterilizing, and degassing the raw milk under vacuum pressure of 0.1~0.7bar; injecting the nitrogen gas into a headspace of a storage tank(2) when storing the sterilized and cooled milk, for preventing the contact of milk with oxygen; and filling a packaging pack with the nitrogen gas when packaging the sterilized milk.
