Antimicrobial effects of selected plant extracts on the shelf life of goat whey

Popis výsledku v původním jazyce

One of the possibilities, how we can increase the shelf life of whey, as well as food in general, is using of essential oils and extracts. The aim of this paper was to evaluate the possibility of addition of an aqueous plant extracts to goat whey to ensure its microbiological stability and prolongation of its shelf-life. There were chosen these herbs: lemon balm (Melissa officinalis L.), wild garlic (Allium ursinum L.), rosemary (Rosmarinus officinalis L.) and Baikal skullcap (Scutellaria baicalensis L.). The aqueous extracts in the amount of 5% were added into goat whey. These samples were stored at 6 °C for four weeks. The microbiological analysis (determining the groups: total plate count, coli-form bacteria, enterococci, thermo-resistant microorganisms), measuring of pH and titratable acidity were performed during storage. The rosemary extract was the only one that significantly reduced the titratable acidity of goat whey. The other three extracts showed mild decrease of titratable
