Abstract
Provided is a method whereby a dairy product having a rich and creamy texture can be obtained by reducing or removing a reaction inhibitor of a protein deamidating enzyme contained in a raw material milk having low heat history to thereby more efficiently and more effectively treat the raw material milk having low heat history with a protein deamidating enzyme. A raw material milk having low heat history is treated with a protein deamidating enzyme after or simultaneously with a treatment, such as an addition of a calcium chelating agent, for reducing a protein deamidating enzyme inhibitor.
Claims32
A method for producing modified milk, comprising:
- treating a raw material milk selected from the group consisting of raw milk, LTLT sterilized milk, and HTST sterilized milk to reduce an inhibitor of a protein deamidating enzyme;
- and
- treating said raw material milk with a protein deamidating enzyme,
- wherein said treating to reduce an inhibitor of a protein deamidating enzyme comprises addition of a calcium chelating agent to said raw material milk in an amount of 0.2 to 1.0 g per 100 g of the raw material milk.
A method for producing modified milk, comprising:
- treating a raw material milk selected from the group consisting of raw milk, LTLT sterilized milk, and HTST sterilized milk to reduce an inhibitor of a protein deamidating enzyme;
- and
- treating said raw material milk with a protein deamidating enzyme,
- wherein said treating to reduce an inhibitor of a protein deamidating enzyme comprises addition of an alkaline material to said raw material milk in an amount of 0.01 to 0.5 g per 100 g of said raw material milk.
A method for producing modified milk, comprising:
- treating a raw material milk selected from the group consisting of raw milk, LTLT sterilized milk, and HTST sterilized milk to reduce an inhibitor of a protein deamidating enzyme;
- and
- treating said raw material milk with a protein deamidating enzyme,
- wherein said treating to reduce an inhibitor of a protein deamidating enzyme comprises addition of a reducing material to said raw material milk in an amount of 0.0001 to 0.1 g per 100 g of said raw material milk or addition of yeast extract containing a reducing agent in an amount of 0.0001 to 0.1 g per 100 g of said raw material milk.
A method for producing modified milk, comprising:
- treating a raw material milk selected from the group consisting of raw milk, LTLT sterilized milk, and HTST sterilized milk to reduce an inhibitor of a protein deamidating enzyme;
- and
- treating said raw material milk with a protein deamidating enzyme,
- wherein said treating to reduce an inhibitor of a protein deamidating enzyme comprises removal of a low molecular weight fraction, having a molecular weight of 10,000 or less, from said raw material milk.
