Abstract
Soft and hard types of cheese are prepared from cow milk by a method of using a milk coagulating enzyme from Bacillus substilis mesentericus. The method involves increasing milk acidity before pasteurization to from 0.189 to 0.216% lactic acid, adding an amount of calcium chloride subsequent to pasteurization 2 to 4 fold over that employed in the prior art and adding a sufficient amount of milk coagulating enzyme to cause coagulation within 25 to 40 minutes. Soft and hard cheese prepared by this process have a taste and consistency equivalent to that of soft and hard cheese prepared with rennet from calf stomachs.
Claims1
In a process for preparing hard and soft cheese from cow milk comprising the steps of:
- 1. mechanically cleaning of supply of cow milk;
- 2. cooling said milk;
- 3. pasteurizing the milk;
- 4. again cooling the milk;
- 5. adding a starter comprising lactic acid microorganisms to the milk;
- 6. adding the equivalent of 0.025 to 0.030% by volume based on the milk a solution of 50% calcium chloride to the milk;
- 7. adding liquid rennet to the milk to produce coagulation;
- 8. and processing the cheese product;
- the improvement which comprises:
- 1. increasing the acidity of the milk before pasteurization to about 21.degree.-24.degree. T (0.189 to 0.216%) lactic acid;
- 2. increasiing the said equivalent amount of calcium chloride described in step 6 added to the milk by 2 to 4 fold;
- 3. adding sufficient of the enzyme obtained from Bacillus subtilis mesentericus to produce coagulation within 25-40 minutes.
