Because the pollen has a hard outer wall that is resistant to acids, alkalis, and corrosion, the academic community once believed that bee pollen can only be absorbed and utilized if it is broken. However, many studies have shown that bee pollen does not need to break the wall as a food, because there are germination holes and germination grooves on the pollen wall. Under the action of enzymes in the gastrointestinal tract and enzymes, the nutrients of pollen can pass through the germination hole and germination. The trench penetrated. After the pollen breaks the wall, it is more susceptible to pollution and is not conducive to preservation. However, pollen as a cosmetic raw material must be broken because the skin does not have the ability to digest. However, when pollen is used as a raw material for further processing, it is necessary to break the wall to ensure that the nutrients of the pollen are extracted.
