Abstract
Abstract A method of producing a low-fat cheese product comprises the steps of inoculating milk having a fat content of between 0.3% and 1.5% with a culture of Lactobacillus bulgaricus and Streptococcus thermophilus and with a culture of Lactobacillus casei in addition to a normal cheese starter culture whereby the culture of Lactobacillus bulgaricus and Streptococcus thermophilus produce the required flavor and rapid fermentation of lactose and the culture of Lactobacillus casei assists in hydrolysis of protein. Syneresis of the curd is impeded by the addition of a monovalent cation such as sodium in the form of sodium chloride.

Claims Analysis

Claim 1
Independent Claim
231 words
The method of manufacturing a reduced fat content cheese from a pasteurized starter batch of milk innoculated with a starter culture and having a standardized fat content of about 0.3% to about 1.5%, comprising the steps of: (a) adding to said starter batch an amount of about 0.1% to about 1.0% of a Lactobacillus bulgaricus culture, an amount of about 0.1% to about 1.0% of a Streptococcus thermophillus culture and an amount of about 0.05% to about 0.3% of a Lactobacillus casei culture; (b) adding an amount of a coagulating enzyme to said batch, said amount sufficient to cause coagulation upon heating; (c) maintaining said batch at a temperature of about 29° C. to about 45° C. for a time sufficient to permit coagulation of said batch into curd and whey; (d) cutting said curd; (e) agitating said curd and whey and thereby expelling moisture from said curd; (f) removing a substantial portion of said whey; (g) adding a pre-determined amount of heated water to said curd and whey for controlling the pH of said whey; (h) adding sufficient sodium chloride to said curd and whey to conrol shrinkage of said curd; (i) agitating said curd and whey; (j) draining off free liquid consisting essentially of water and whey and thereby providing conditioned curd; and, (k) forming said conditioned curd into cheese having a pH of about 5.1 to about 5.5.
