Influence of Varying pH and Algin/Calcium Binders on Selected Physical and Sensory Characteristics of Structured Beef

摘要

ABSTRACTStructured beef was prepared with eight combinations of the ingredients (sodium alginate, calcium carbonate, lactic acid/calcium lactate) used to bind meat with the algin/calcium gelation mechanism at nine pH values (4.1–6.4) in order to evaluate their influence on its physical and sensory characteristics. Products with alginate alone were similar to samples from the treatment without binders. The combination of alginate/calcium/lactate gave products of higher values (P>0.05) for parameters such as hardness in the raw state, bind and penetration than all other treatments. Decreasing pH values increased raw and cooked product hardness and penetration force. Products of pH values 5.7–5.8 were superior to other treatments in bind scores evaluated by a sensory pa
