A method for producing a cheese product directly from milk in a short period of time is provided. In the method, pasteurized milk is treated with lactic acid to provide an acidified milk product. The resulting acidified milk is then subjected to ultrafiltration (UF), and optionally diafiltration (DF), to form a UF retentate (or UF/DF retentate if diafiltration is used) which is concentrated by about a factor of about 4 to about 7 and which has a lactose concentration of about 2.5 to about 4.0 percent (UF retentate) or about 0.5 to about 2.5 percent (UF/DF retentate). After adding lactic acid and salt, the UF or UF/DF retentate is subject to an evaporation step to form a precheese. The resulting precheese has a total solid content of about 30 to about 70 percent. The precheese, with added flavorants and other additives (including, for example, emulsifying salts) is then subject to conventional cheese processing conditions in, for example, a laydown cooker. The resulting process cheese or process cheese-type product is ready for immediate packaging and does not require a separate curing step. The process cheese or process cheese-type product is similar in flavor and texture characteristics to conventional process cheeses.

[ What is claimed is:] [1.] A method for producing a process cheese-type product directly from milk, said method comprising:(a) treating pasteurized milk with a first edible acid to obtain acidified milk having a pH in the range of about 5.9 to about 6.5;(b) reducing the lactose content of the acidified milk to about 2.5 to about 4.0 percent and increasing the solids content to about 15 to about 50 percent using ultrafiltration to obtain a UF retentate;(c) adjusting the pH of the UF retentate to about 4.9 to about 6.3 percent by the addition of a second edible acid to form a treated UF retentate;(d) removing sufficient water from the treated UF retentate by evaporation to obtain a precheese having a total solid content of about 30 to about 70 percent; and(e) blending emulsifiers and flavor additives with the precheese at a temperature of about 150 to about 240' F. for a time sufficient to obtain a homogenous process cheese-type product;wherein enzymes, cultures, or microorganisms are not employed and wherein there is no formation or separation of curds and whey.
