Abstract: METHOD FOR MANUFACTURE OF REDUCED FAT CHEDDAR CHEESE      Abstract of the Invention The present invention is directed to a method for making a higher moisture, reduced fat natural cheddar-type cheese product from partially or wholly fat reduced milk.  The cheddar-type cheese product of the present invention has from about 45% to about 58% moisture and from about 1.3% to about 15% butterfat.  In the method of the invention for making a reduced fat natural cheddar-type cheese, milk is standardized in fat content to produce a milk substrate having from about 0.05% to about 2% milkfat.  A culture system is added to the standardized milk.  The culture system comprises a lactic acid starter culture and a ropy culture. Thereafter, the milk is fermented and set with a milk coagulating enzyme.  The coagulum is cut to provide curd particles and whey and the curd particles are cooked in the whey at a temperature below the optimum growth temperature of the ropy culture.  The whey is drained from the curd and the curd is rinsed, salted and filled into containers.  The curd is pressed and vacuumed to remove additional whey, the container is sealed and the curd is cooled in the container.  Thereafter, the curd blocks are cured to provide a natural cheddar type cheese product having a reduced fat level which is from about 40% to about 60% of the fat level of conventional cheddar-type cheese products.
