Popis: Two experiments were conducted to investigate the effects of ionic strength and type of chloride salt on the performance of carrageenans in a model system. Reducting the NaCl content from 2 to 1% caused excessive cooking losses and increased firmness of the meat mixtures. Increasing the NaCl level from 2 to 3% did not improve yields, but the addition of kappa- or iota-carrageenan reduced cooking losses at these salt levels. CaCl2 caused instability of the meat mixtures and poor water retention. Combinations of KCl with iota- or lambda-carrageenan resulted in low cooking losses. The presence of potassium ions but not sodium, resulted in improved water-binding by the lambda-carrageenan.
