Organic adds play a very important role in food products, affecting their taste and smell, as well as determine microbial stability. The organic acid composition in cider depends on the quality of the raw material, a treatment used in the production of juice (e.g., filtration, pasteurization), and the conditions of fermentation process (temperature, time, yeast and lactic acid bacteria strains). In this study, organic acid composition of ciders available on the Warsaw market was investigated. The material used in study were ciders produced in Poland and products imported from France, Estonia, Belgium, Lithuania and England.
