Summary
Researchers compared three environmentally friendly methods for extracting beneficial compounds from Chaga mushrooms collected from Serbia and Mongolia. The study found that heating mushroom material with water under pressure (subcritical water extraction) was the most effective at extracting important compounds like glucans and phenols. These findings help the mushroom supplement industry choose the best extraction method based on which compounds they want to produce.
Background
The mushroom industry requires implementation of green extraction technologies to reduce carbon footprint and environmental impact. However, limited information exists comparing the chemical composition differences between various green extraction techniques when applied to medicinal mushrooms.
Objective
To compare the effects of selected green extraction techniques (subcritical water extraction, microwave-assisted extraction, and ultrasonic-assisted extraction) on the chemical composition of Chaga mushroom extracts from Serbian and Mongolian sources.
Results
Subcritical water extraction at 200°C produced significantly higher yields of total polysaccharides and glucans compared to other techniques. Microwave-assisted extraction with 50% ethanol showed the highest yield of total phenols. Glucose was the most dominant monosaccharide in subcritical water extracts, especially at 200°C, while chlorogenic acid was the most abundant phenolic compound across all extracts.
Conclusion
Subcritical water extraction is recommended as the most efficient method for extracting commercially important compounds, particularly glucans and phenols, from Chaga mushrooms, enabling composition-based technology selection in the mushroom supplement industry.
