The main purpose of this study was to compare the quality of the different types of unpasteurized beer from a profile unit in Bucharest area and samples coming from the market. The material was represented by 12 unpasteurized blonde beer samples divided in 4 batches. The samples were submitted to physico-chemical and microbiological analysis determining: alcohol concentration, original, apparent and real extract, density, limpidity, colour, pH, RDF (real fermentation degree) and microbial loading in order to verify the efficiency of pasteurization using microfiltration. pH is one of the most important parameters regarding the taste and beer stability, the values obtained were between 4.24- 4.63. Another important parameter was the microbial loading, which was negative both in aerobic and anaerobic media. After analyzing all the results obtained, it is concluded that these products comply with the quality standards imposed by the legislation in force.
