Abstract: There is disclosed a formed food product of microfibrillar protein comprising a bundle of microfibrillar protein having a diameter of fiber of 10.mu. or less and a high heat resistance (A) and a microfibrillar protein having a diameter of fiber of 10.mu. or less and a low heat resistance (B) and optionally one or more fillers and/or other additives, which has similar structure and texture to those of cooked natural meats and has excellent stability to hot water cooking, excellent shape retention and good texture, and hence is useful as an artificial meat product.

Abstract: A fibrous milk protein product having a high tensile elongation (115 to 380%) and an excellent stability to hot water cooking (tolerant to treatment in hot water of 135.degree. C. for 4 minutes) which is produced by forming the starting milk protein into a fibrous composition and then treating the fibrous composition in an aqueous solution containing at least one of sodium, potassium and calcium salts and also an aldehyde type crosslinking agent having a ratio of molecular weight (M) to number of aldehyde groups (n) of 120 to 360 (e.g. lactose) at a pH of 2.5 to 6.5 and at 100.degree. to 140.degree. C. for 20 minutes to 3 hours.

Abstract: A process for producing a meat-simulating, fibrous high-protein food from a starting milk material such as a milk, a skim milk, a casein or the like, which comprises the steps of (1) converting the starting milk material into a fibrous composition by a known method such as gelling the starting milk material and applying a stress to the resulting gel composition; (2) after or during the conversion step, prestabilizing the resulting fibrous composition in an acidic bath of pH 0 to 5 containing 0.5 to 25% by weight of one or more specific acidic compounds for 10 seconds to 5 minutes; and then (3) actually stabilizing the resultant fibrous composition in a saline bath of pH 2.5 to 6.5 containing at least one salt selected from a potassium salt, a sodium salt or a calcium salt in an amount of 0.3 to 6 gram equivalents/L as the total cation concentration of the bath, at 90.degree. to 130.degree. C. for 20 minutes to 3 hours.
