The influence of salt content in fresh cheeses on microbiological, chemical and sensory parameters

Original language description

Cheeses are one among foods with a higher salt content. In this experiment, we focused on fresh cheese. The easiest way to influence the salt content is by shortening the salting time. Microbial, chemical and sensory parameters were evaluated after the production, after 7 and 14 days of storage. Lactococci numbers gradually decreased and after 14 days of storage they dropped to a count 108 CFU/g. A significant increase of yeasts was found in non-salted cheeses packed only by sealing in a protective film without air extraction. Another monitored group were halotolerant microorganisms, which increased to the order of 104 CFU/g during storage of cheeses from the first series of production, especially in samples without salting or with a significantly reduced salt content. In relation to sensory evaluation, the lowest possible salt content in cheeses was set to 0.5-0.6 % of NaCl. The different salt content in the samples did not affect the chemical parameters or the number of lactococci. The economic and technological demands of the production of fresh and reformulated fresh cheeses are practically the same.
