Is it unhealthy to oversoak shiitake mushrooms?

Shiitake mushroom has high nutritional value, and has a strong fragrance, belongs to the top grade in mushroom food, regular consumption can also prevent liver cirrhosis, inhibit the increase of blood cholesterol content, has a high health care effect, so people like to eat. Since shiitake mushrooms are mostly dried products, they should be soaked in water before eating, and many people will soak them in water for a long time in order to fully soak them, but this practice is actually not scientific.

Because shiitake mushrooms are rich in ergosterol, this substance is converted into vitamin D when exposed to sunlight, and if shiitake mushrooms are over-soaked or washed with water, the amount of vitamin D in them will be lost. In addition, excessive soaking will also greatly reduce the aroma of shiitake mushrooms, resulting in "shiitake mushrooms are not fragrant".

You can eat it, but after soaking for a long time, there is a loss of nutrients, and it doesn't taste good.

When soaking dried shiitake mushrooms, it is best to use warm water of about 20 -35, which can not only make the shiitake mushrooms easier to absorb water and become soft and swelling, but also make the guanylate fully decompose and exude umami. If you soak it in cold water, the amount of uronitic acid decomposition is less, and the taste of the soaked shiitake mushrooms will naturally be worse. It is best not to soak for too long, and when the mushroom caps are all soft, you should immediately remove and drain them.

If you add a little sugar to the water when soaking, it can reduce the loss of mushroom flavor and guanylate during the water change process, so that the cooked shiitake mushrooms taste better. Soaking dried shiitake mushrooms Before cooking, rinse the surface of the shiitake mushrooms with cold water, remove the roots of the shiitake mushrooms with the stem, and then place the "gill pages" facing down in a basin of warm water to soak, and after the shiitake mushrooms become soft and the "gill pages" are opened, then gently stir with your hands in one direction to let the sediment slowly sink to the bottom of the basin. The water used to soak shiitake mushrooms can be used to remove sediment.

If you add a little sugar to the warm water in which the shiitake mushrooms are soaked, the taste will be more delicious after cooking.
