Mushrooms

1 . Evolution of Mushroom Consumption

Truffles, morels, porcini mushrooms, wild mushrooms… dried and powdered mushrooms are experiencing considerable growth, driven by trends in functional foods, natural medicine, and nutraceuticals.

Prized for their adaptogenic, immunostimulating, and nutritional properties, they are becoming increasingly popular in the food industry, as well as in dietary supplements and cosmetic products. However, their harvesting and drying methods expose them to microbiological risks that must be controlled.

2 . What are the microbiological risks?

Dried mushrooms are particularly susceptible to microbiological contamination. Harvested in their natural environment and dried under varying conditions, mushrooms can harbor pathogenic bacteria (salmonella, E. coli, Listeria), molds, and yeasts that thrive in cases of improper storage or excessive residual moisture.

These contaminations can occur at any stage: harvesting, drying, storage, transport, and packaging. A non-compliant batch exposes the operator to costly product recalls, import refusals, and regulatory penalties.

3 . What treatment is used?

Saturated steam pasteurization under vacuum is the most suitable treatment for dried and powdered mushrooms. This process operates along three dimensions (temperature, time, and pressure) to effectively eliminate pathogens while preserving the active properties, aromas, texture, and organic certifications of the products.

The parameters are customized according to the type of mushroom, its specific characteristics, and the microbiological thresholds to be met. Our experts will assist you in determining the protocol best suited to your situation.
