Abstract

The aim of our study was to evaluate the influence of the addition of Satureja montana L. (Sm) products fermented with bacteriocin-like inhibitory substances (BLIS) producing lactic acid bacteria (LAB) Lactobacillus sakei KTU05-6, Pediococcus acidilactici KTU05-7 and P. pentosaceus KTU05-9 on ready-to-cook minced pork (RCMP) quality parameters. The LAB strains showed good growth in Sm media (from 8.6 log cfu/g till 9.3 log cfu/g). The addition of the fermented Sm product at 3% level increased acceptability of RCMP and reduced the total number of Staphylococcus spp. and Streptococcus bacteria (p<0.05). The use of fermented Sm products significantly increased ρ-cimene, γ-terpinene and carvacrol contents in RCMP and reduced dry matter content and pH values, increased drip loss, tenderness and water holding capacity, therefore influenced the cook loss. Fermented Sm at 3 % level may be useful for meat processing, thus increasing acceptability, ρ-cimene, γ-terpinene, carvacrol content and shelf-life of products.
