Mushroom mycelium grown in liquid fermentation produces many beneficial compounds like polysaccharides and proteins that support immune function and may help fight cancer and oxidative stress. These fermented mushroom products can be added to foods, beverages, and health supplements to boost their nutritional value and health benefits. Studies show that fermented mushroom mycelium sometimes contains higher levels of beneficial compounds compared to whole mushroom fruiting bodies, making it a promising ingredient for functional foods and health products.
