A recent study on cottage cheese brands available in the Russian market has found that samples from three brands ('House in the Village', 'Prostokvashino', and 'Talitsky') meet or exceed the advanced standard of Roskachestvo. However, violations of other product safety requirements were also identified. The study revealed the presence of microbial transglutaminase in products from the 'Fresh Tomorrow' and 'Slavic Lace' brands, a substance prohibited for use in food production in Russia since 2020 due to safety concerns.
