Why quality control matters for mushrooms
Food supplements are tightly regulated to ensure traceability, hygiene and food safety. With mushrooms, one characteristic calls for particular care: they are natural bio-accumulators.
Mushrooms: natural bio-accumulators
Mushrooms can concentrate substances from their environment – essential minerals, but also pollutants such as mercury, lead, cadmium or arsenic. This ability is so remarkable that fungi are being studied to clean up contaminated soils (mycoremediation). It also means the growing environment must be carefully controlled.
The growing substrate
Most mushrooms used in supplements are 'white-rot' fungi that break down lignin. Commercially, they are grown on substrates such as hardwood sawdust or straw. Any pollution in those materials – from industry, pesticides or fertilisers – can end up in the mushroom.
Why it matters for extracts
Extracts concentrate the mushroom's compounds: around 15 kg of fresh Reishi is needed to make 1 kg of our standardised extract. Any contaminant present would be concentrated too, which is why testing every batch is essential.
What organic certification means
Organic certification confirms that the mushrooms are grown according to organic production rules – without synthetic pesticides or fertilisers. It does not, on its own, guarantee the absence of contaminants such as heavy metals; that requires specific laboratory analysis.
Our quality controls
Under the Hifas Quality System, every batch is tested at source, after extraction and as a finished product, including microbiological, pesticide (more than 400 substances), heavy-metal and gluten analyses, to confirm that results are within legal limits.
