AbstractThe objective of this study was to optimise the acceptability of reduced-salt cooked ham containing a mixture of glycine and yeast extract as flavourings by using response surface methodology. Twelve different formulations were prepared with varying levels of salt and the two flavourings, according to a mixture design. The sensory properties were assessed along with the instrumental texture and colour. A multiple factor analysis showed that higher scores in tenderness, saltiness and juiciness were positively correlated, whereas instrumental hardness and chewiness were negatively correlated with acceptability. Response surface plots and optimisation software allowed the inference of two optimised formulations: HO1 with 1.3% salt and yeast extract content of 0.33%; and HO2 with 1.27% salt, 0.2% yeast extract and 0.16% glycine. A panel of 100 consumers found no significant differences in overall acceptability when both were compared to a control (1.63% salt). These results show it is possible to manufacture consumer accepted cooked ham with up to 20% salt reduction.
