Abstract: Mutational inactivation of proteins involved in para-cresol production in certain milk products results in improved taste and odor. The undesirable para-cresol forms over time as a result of enzymes produced by the bacterium that produces gellan gum. Since the gellan is typically used in a relatively unpurified form, the enzymes are added to the milk along with the gellan. Inactivation of the enzymes is a genetic means of eliminating the enzymes without requiring any additional purification or processing.

Thus, this method is useful in the manufacturing of a variety of cheese types originating from a single curd.

Abstract: An improved method for making cheese is provided. The method comprises pasteurizing and acidifying one or more dairy components to obtain a cheese diary product. The cheese dairy product is coagulated to form a coagulum comprising curd and whey. The coagulum is cut and the whey is removed therefrom, thereby leaving the curd. The curd is heated and kneaded to produce a fiberous mass. An extender is added to the curd or to the fiberous mass, and the extender comprises at least one source of fat. The fiberous mass is processed to produce a cheese product. By this method. By this method, the casein/fat ratio can be increased early in the process so that less fat is wasted through removal with the whey. The fat content of the cheese product can then increased later in the process through the use of the extender, thereby creating a more cost-effective product.

The processes involve adding a relatively small (e.g., about 0.005 to about 0.1 percent) but effective amount of the ionic gum (e.g., xanthan, gellan, carrageenan, alginate gums, low methoxy pectin, or mixtures thereof) before a fermentation step, preferably prior to initial homogenization/heating steps, to provide ionic gum-dairy protein interaction without causing coacervation with protein. In certain preferred embodiments, xanthan gum is used due to its cold water solubility, consistent composition, availability, and low cost.

Abstract: A method for eliminating the uncooked curd defect in process cheese products associated with fortification of milk during the natural cheese make process. This fortification results in a significant increase in the amount of calcium bound in the casein micelle. The fortified milk is subjected to an acid or acid producing material that quickly lowers the pH either before or after pasteurization to a pH of approximately 6.6 to 5.70. The acidification is performed under turbulent conditions to maintain milk protein native integrity. The acidification step results in a significant migration of calcium out of the casein micelle and into a soluble form that is carried away with the whey stream. The acidified fortified milk is then subjected to the conventional cheese making process. The resulting natural cheese can then be further processed into a process cheese product without the risk of uncooked curd particles in the finished product.

Abstract: Methods of making acid and rennet-based cheeses include processing a previous lot of milk to produce curds and whey from the previous lot of milk, and removing the whey from the curd. For cottage cheeses, curds are washed with a wash water. Whey and wash water (when used) include fine particles of curd, which are collected, added, and mixed into a subsequent lot of milk preferably using a mixer such as a homogenizer or colloid mill. Mixing preferably reduces the fine particle size of at least a plurality of the fine particles and increases the total amount of surface area thereof. Fine particles are reincorporated into the matrix of the curd made from the subsequent lot of milk, which increases curd yield. Also provided is a higher yield cheese that is made from a subsequent lot of milk that includes fine particles of curd from a previous lot of milk.

Abstract: A process for the manufacture of a probiotic cheese, such as Cheddar cheese, comprises adding a 0.0-5.5% inoculum of a strain of Lactobacillus paracasei, which is non-pathogenic, acid and bile tolerant and adherent to human epithelial cells, as a starter adjunct to cheese milk, said L. paracasei strain being capable of growing during the ripening phase to a level of 107 cfu/g or greater. The L. paracasei strains are found to grow and proliferate to high cell numbers (in excess of 108 cfu/g) in the cheese over eight months of ripening, even when added at a relatively low inoculum. The presence of the L. paracasei strains is found to have negligible effects on cheese composition, flavor and aroma.

Abstract: A method is disclosed for making reduced calorie cultured cheeses whereby the natural lipid content of milk is replaced with colloidal forms of synthetic or chemically structured lipids displaying low to no human digestibility.

The coagulum is then processed by means similar to that employed for naturally fermented cheeses.
