This paper describes the analysis of drying and taste additives influence on the changes of chemical composition and quality parameters of Pleurotus Ostreatus and Agaricus bisporus mushrooms and their ready-to-cook mushroom foods. We tested and scientifically motivated the impact of drying on the protein substances changes and carbohydrates changes (contents of glycogen, dextrines, reducing substances, cellulose) of ready-to-cook mushroom foods.
The optimum mode of hydrothermal treatment of Pleurotus Ostreatus and Agaricus bisporus mushrooms has been determined. The impact of hydrothermal treatment on the changes of the activity of polyphenol oxidase, protein substances and carbohydrates losses of ready-to-cook mushroom foods were tested.
It has been discovered that with the introduction of salt and citric acid in the solution the amount of protein losses has decreased in Pleurotus Ostreatus by 5.0-29.5 %, Agaricus bisporus – 5.7-19.0 %.
