The data of researches on conformity of fermented milk cheese and termized cheese products of different trademarks with the requirements of national standards of Ukraine (DSTU 4554:2006 "Cottage cheese. Specifications", DSTU 4503:2005 "Products of cheese. General technical conditions"), which are sold in retail trade network, in terms of quality and safety. Identification of their naturalness for falsification of sodium bicarbonate and starch was carried out. It was established that by the indicators: organoleptic (smell, consistency and taste), physicochemical (mass fraction of fat, protein, water, titrated acid, presence of phosphatase enzyme), investigated sour milk cheese (samples №№. 1,2,3) met the requirements of DSTU 4554:2006. The titrated acidity in cheese products (samples №№ 4,5), mass fraction of fat and which does not meet the requirements of DSTU 4503: 2005, was reduced. All investigated samples of sour milk cheese according to microbiological parameters (presence of coli-shaped bacteria of the group of Escherichia coli, number of molds, yeast, pathogens, in particular, Salmonella, Staphylococcus aureus) corresponded to DSTU 4554:2006 and DSTU 4503:2005. The number of lactic acid bacteria tested sour milk cheese and cheese products did not meet the regulations of the applicable national standards. The falsification of the investigated thermalized cheese products with sodium bicarbonate and starch was detected. Express, easy-to-carry methods for detecting falsification of fermented milk cheese and cheese products with sodium bicarbonate (using bromothymol blue with a mass concentration of 0.04%) and starch (for detecting its grain inclusions, using a solution with the use of a solution with the use of a solution, have been developed, tested and implemented 0.1 mol/dm3) by microscopy
