  • Preparation of cheese with ropy lactic acid bacteria
    Patent number: 4243684
    Abstract: Cheese made from milk and/or milk-by-products concentrated by membrane filtration sometimes has the disadvantage of having a mealy and/or sandy texture. This can be overcome by using selected ropy cultures of lactic acid bacteria instead of the normal non-ropy cultures used for acidifying the milk product. The effect is particularly useful in the preparation of soft cheese having a smooth texture.
