Abstract
In this study, the effects of potassium lactate (PL, Potassium-L-2-hydroxy-propionate, Potassium-L-Lactate) usage (0%, 0.5%, 1.0%, 2.0% PL of curing mixture) in addition to NaCl and sodium nitrite as curing agent on the physico-chemical, microbiological and sensory properties of ready-to-eat pastırma were investigated. The usage of PL affected pastırma properties as pH (P < 0.01), TBARS (P < 0.01), salt (P < 0.01), residual nitrite content (P < 0.01), a* value (P < 0.01), microbial properties (P < 0.01) (total aerobic mesophylic bacteria, lactic acid bacteria, Micrococcus/Staphylococcus, yeast-mould count) and amino acid levels [lysine (P < 0.01), isoleucine (P < 0.01), leucine (P < 0.01), methionine (P < 0.05), phenylalanine (P < 0.01), valine (P < 0.05), threonine (P < 0.01), tryptophan (P < 0.05), aspartic acid (P < 0.05), glutamic acid (P < 0.05), asparagine (P < 0.05), serine (P < 0.01), histidine (P < 0.01), glycine (P < 0.01), alanine (P < 0.01), proline (P < 0.01), cystine (P < 0.05) and norvaline (P < 0.01)]. According to results of sensory analysis, the difference among pastırma samples including PL was not significant (P > 0.05).
