The aim of the present study was to establish the possibilities for improving the processed cheese quality by the addition of natural spice extracts. Four batches of processed cheese were produced by using of Piper nigrum L., Satureja hortensis L. and their natural extracts. Control and test samples w ere stored at 5±1ºC for 10 days. Each batch of processed cheese was analyzed for dry matter, pH, titrable acidity, fat and salt content. Microbiological analysis of spices, spice extracts and processed cheese samples was performed. Sensory evaluation of all batches was also performed. A similarity in the composition of control and test samples was established. Total aerobic colony count of test samples was approximately 10 times lower than in the controls. Processed cheeses produced by using of spice extract had higher sensory evaluation coefficients than the controls. It was concluded that the replacement of Piper nigrum L. and Satureja hortensis L. spices with their extracts improved significantly the processed cheese microbiological and sensory quality.
