ActiveCN101564062AMaintain drawabilityLow heating temperatureCheese manufactureEngineeringBrowning reaction
The invention discloses a method for preparing a platy or lump processed cheese, comprising steps as follows: (1) shearing and mixing materials which contain natural cheese, butter oil, emulsifying salt and water; (2) heating under the shearing condition; (3) shearing emulsification; (4) forming the platy or lump cheese and then cooling. The method is characterized in that: both the shearing condition in step (2) and shearing emulsification in step (3) use a cutter with a blade thickness of 2-10mm, at a shearing rotating speed of 200-800rpm; in step (2), the materials are heated to 70-80 DEG C; and in step (3), the temperature for shearing emulsification ranges from 70 to 80 DEG C. The invention also discloses a platy or lump processed cheese prepared by the method. The invention improves the prior technique for preparing processed cheese by using low shearing condition to overcome the defect that the prior processed cheese has no stringiness, and provides a platy or lump processed cheese with stringiness, favorable mouth feel and texture and long guarantee period without browning reaction.
