Video Summary

The mass of fresh mushrooms decreases by 75% during drying. Starting with 100 grams of fresh mushrooms, which contain 80 grams of water and 20 grams of dry matter, drying reduces the water content. With the original 20 grams of dry matter becoming 80% of the final mass, the dried mushrooms weigh 25 grams: 20 grams of dry matter and 5 grams of remaining water. Consequently, the mass decreases by 75 grams, representing a 75% reduction in mass.
