Champignons are one of the most commonly used mushrooms in cooking. On sale they can be found in any store, however, these products may not always be fresh. To understand that the champignons have deteriorated, and not to ruin your future culinary masterpiece, you can use one of the methods suggested below.
Can champignons go bad in the refrigerator?
Champignons, like any other food, have their own maximum permissible shelf life in the refrigerator. When deviating from the recommended parameters of temperature or humidity, it decreases sharply. Under such conditions, as well as when the permissible shelf life is exceeded, intensive decomposition processes begin in the tissues of the fungus, leading to spoilage of the product.
How to understand that mushrooms are gone
