Abstract
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.
