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.
