Herein is disclosed a method for modifying raw material milk, wherein a reducing agent such as a thiol compound is added when transglutaminase is caused to act upon raw material milk for a dairy product, whereby the reactivity of the transglutaminase to the raw material milk such as raw cow milk, can be improved and the milk protein can, in turn, be modified effectively. From the thus-modified raw material milk can be produced dairy products such as yogurt, cheese and powdered milk improved in physical properties, mouthfeel or texture.

1. A method of preparing a dairy product, comprising modifying a raw material milk by causing transglutaminase to act on said raw material milk, wherein a reducing agent is added to said raw material milk when said transglutaminase is caused to act on said raw material milk. 2. The method of claim 1
1. A method of preparing a dairy product, comprising modifying a raw material milk by causing transglutaminase to act on said raw material milk, wherein a reducing agent is added to said raw material milk when said transglutaminase is caused to act on said raw material milk. 2. The method of claim 1, wherein said raw material milk is selected from the group consisting of raw milk, skimmed milk, partially skimmed milk, and processed milks thereof. 3. The method of claim 1, wherein said raw material milk is a casein-containing solution obtained by processing a raw material milk selected from the group consisting of raw milk, skimmed milk, partially skimmed milk, and processed milks thereof. 4. The method of claim 1, wherein said reducing agent is at least one compound selected from the group consisting of reduced glutathione, cysteine, γ-glutamylcysteine, sulfurous acid, ascorbic acid, erythorbic acid, salts thereof, and preparations containing at least one of these reducing agents. 5. The method of claim 1, wherein said reducing agent is added in an amount of 1×10-5to 1×10-1g per 1 gram of non-fat milk solid, present in said raw material milk. 6. The method of claim 1, wherein said transglutaminase is caused to act upon the raw material milk in an amount of 0.001 to 20 units per 1 gram of milk protein, present in said raw material milk. 7. The method of claim 1, wherein said raw material milk is selected from the group consisting of raw milk, skimmed milk, partially skimmed milk, and processed milks thereof, and wherein said reducing agent is at least one compound selected from the group consisting of reduced glutathione, cysteine, γ-glutamylcysteine, sulfurous acid, ascorbic acid, erythorbic acid, salts thereof, and preparations containing at least one of these reducing agents. 8. The method of claim 7, wherein said reducing agent is added in an amount of 1×10-5to 1×10-1g per 1 gram of non-fat milk solid, present in said raw material milk. 9. The method of claim 8, wherein said transglutaminase is caused to act upon the raw material milk in an amount of 0.001 to 20 units per 1 grain of milk protein, present in said raw material milk. 10. The method of claim 7, wherein said transglutaminase is caused to act upon the raw material milk in an amount of 0.001 to 20 units per 1 gram of milk protein, present in said raw material milk.
