Why pasteurize mushroom substrate?

Pasteurization of Mushroom substrate.

Pasteurization is a process that has been used for hundreds of years to destroy harmful germs in food. It is commonly known for its role in milk and juice production and was invented by the French chemist and microbiologist Louis Pasteur in 1864. Pasteurization only involves heat (no chemicals) to make foods safe for consumption.

By pasteurizing bulk substrates at 160-180°F, you can ensure that your mushrooms will have the best chance possible to survive. If you are using unpasteurized compost, contaminations are likely to happen, meaning unwanted organisms are growing in your substrate or your mushrooms don’t look good because they are weakened by pathogens.

Pasteurized Compost

We offer a growing medium targeted for gourmet and medicinal mushrooms, however. This organic compost has been tested and altered for five years now to become a highly nutritious, mycelium thriving, well blended formula. Compared to manure, our consumers agree that our substrate is not only more nutritious and odorless, but it is also more moisture controllable. At only $1.50 a pound for pasteurized and $.75 for non-pasteurized, we believe that our compost is the best for its price and better than most higher priced substrates. Pasteurized for three hours at 160 degrees, our medium is contaminate free and will remain this way as long as the filter patched bags remain sealed.
