Reduction of biogenic amine concentration in fermented sausage by selected starter cultures

Abstract

We determined the effects of selected starter cultures for the production and ripening of fermented sausages on their ability to reduce biogenic amines accumulation. Starter cultures used were: Group L: Lactobacillus plantarum; Group X: Staphylococcus xylosus; Group M: Lactobacillus plantarum together with Staphylococcus xylosus; and Group C: control group without added starter cultures. At the end of ripening period, those inoculated with S. xylosus had only a slight effect on reduction of tyramine (21%), histamine (25%) and cadaverine (22%) compared with the control group. Addition of S. xylosus plus L. plantarum effectively reduced tryptamine, phenylethylamine, putrescine, cadaverine, histamine and tyramine by nearly 100, 100, 86, 63, 82 and 43%, respectively. There were no statistically significant (P > 0.05) differences between batches M and L. Results indicated that L. plantarum used in this work had a strong effect on inhibiting the production of biogenic amines.
