Bitter, milk and white chocolate differ in terms of identification, including the content of the total dry residue of cocoa and the mass fraction of fat. The mass fraction of fat is regulated by state standards and is an important indicator of the quality of chocolate. Different receipts of chocolate cause different vitamins content. Chocolate contains a significant amount of tocopherols with high antioxidant activity, this allows preserving unsaturated fatty acids and biologically active components for a long shelf life. Losses of vitamins occur due to their oxidation and transition to more stable forms during storing of chocolate and chocolate products. Unstable and increased storage temperature leads not only to deterioration of organoleptic parameters, but also to a significant decrease in the content of vitamins. Objects of research have been samples of bitter, milk and white chocolate. The change in the content of vitamins during addition and storage at the temperature of 20 °C and under conditions of "accelerated aging" at the temperature of 50 °C in bitter, milk and white chocolate has been studied...
