Mushroom, dried

Dried mushrooms are mushrooms with most of their water removed. The nutrient figures here are calculated from raw mushrooms and describe the dried form. Per 100g, they provide 22g of protein, 6g of fat and 4.8g of carbohydrate, alongside vitamins and minerals, including 110mg of magnesium.

Protein is needed for the growth and repair of body tissues, while magnesium supports normal muscle and nerve function. Drying concentrates nutrients by reducing water content, so the weight of dried mushrooms is not directly comparable with the same weight of fresh mushrooms. Adding water during preparation changes the nutrient concentration by weight. Full nutrient figures are shown in the tables below.

About these figures

Values are per 100g of the food as described (Calculated from raw mushroom). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.
