EFFECT OF GROWTH CONDITIONS ON QUALITATIVE CHARACTERISTICS OF CHAGA MUSHROOM
Abstract
The paper presents a comparative analysis of the output of essential components from the Chaga fungus, depending on the growth conditions. The study compares the samples of Chaga mushroom grown in two different regions of Eurasia - Eastern Siberia and Western Belorussia. Classical method of extracting was used to get water extraction of Chaga; the method suggests that distilled water is poured into a flask with grind Chaga in a ratio of 1:6 and further put in a chamber for 5 hours at a constant temperature of 70В°C. Later, the extract obtained is separated from the meal, which is then filled with distilled water in a ratio of 1:4 and extracted additionally for 5 hours at the same constant temperature. The extracts of the first and second stages are mixed up and further filtered, followed by melanin extracting. An analysis of the qualitative parameters of the fungi was performed by quantifying the melanin content in their composition, since melanin is one of the fungal components, which has a proven therapeutic effect and is in demand by the pharmaceutical industry. The chemical composition of the Chaga samples was studied by the use of spectrometer ?Nicolet-6700?. The authors proved that in the process of water extraction the output of melanin from the Chaga mushroom grown in Eastern Siberia is 1.95% higher than that of the analogue from Western Belorussia. Thus, the authors concluded that harsher conditions of fungus growth lead to a greater accumulation of useful substances in it.
