Název v původním jazyce

The effects of lactic acid bacteria inoculants and forming acid on the formation of biogenic amines in grass silages

Popis výsledku v původním jazyce

Silages were prepared in six laboratory experiments from four direct-cut grassland swards and pure swards of perennial ryegrass and false oat with dry matter contents ranging between 180 and 325g/kg. Grass was fermented at 22oC and silages were stored atthe same temperature for 4 month. Untreated silages (negative control) and silages preserved with 3g/kg of formic acid (positive control) were compared with silages inoculated with commercial strains of Lactobacillus plantarum, Lactobacillus buchneri and a mixed preparation Microsil. The inoculants were applied at a dose of 5. 10 000 000 CFU/g of grass. Seven biogenic amines were extracted from silages with perchloric acid and determined as N-benzamides by micellar electrokinetic capillary chromatography. Common quality parameters of silages were also determined. Tyramine, cadaverine and putrescine were the amines occurring at the highest concentration. As compared to untreated silages, formic acid was most effective to suppress format
