摘要: Bolognas were made in which 20% of the lean meat (beef and pork) was replaced by wet fibrous hide collagen formulated to contain approximately 30, 20 or 10 percent fat final product. All controls (no collagen) have similar content. Objective methods used analyze product paired comparisons data made. The replacement with did not alter functional characters such as raw emulsion stability andpH; cook yield, pH, water activity, density expressible juice cooked bologna. bolognas had higher (P<0.05) texture (increased Shear force value) compared bologna no collagen. As content decreased less red color than without textural changes though detected on instrumental analysis perceptible visual examination
