Raw Material Natural Characteristics

Inonotus obliquus is a wood-inhabiting fungus whose sclerotia naturally accumulate a range of fungal substances during slow growth on birch trunks. Our whole dried chaga sclerotia are harvested at full maturity, then gently dried and sorted to keep the natural fungal structure and original earthy, slightly bitter flavour with light vanilla undertones. With stable physical properties and flexible application options, this botanical raw material fits the global market trend for natural, plant-based and clean-label food ingredients.

• Natural Fungal Source: Harvested from mature birch trees in cold forest regions, sourced from sustainable harvesting zones, without mixing with birch bark residues or foreign debris.

• Mild Drying Process: Low-temperature drying treatment reduces moisture while limiting heat impact, helping maintain the natural aroma and texture of chaga sclerotia.

• Consistent Grading Standard: Unified sorting and chunk classification ensure similar block dimensions and appearance between batches, convenient for end product formulation and packaging design.

• Wide Application Flexibility: Whole chaga blocks can be chipped or crushed further, compatible with many beverage and food systems for different production needs.
