1, sealed and stored in a dry, cool and ventilated place;

Second, scallop column, also known as Yaozhu, is the stigma meat of Jiang Yao (shellfish). Because it is usually dried in the sun, it is also called scallop scallop.

There are about 30 kinds of shellfish that can be used to make Yaozhu, and the common ones are "Jiangyaozhu", "Yuanbei", "Riyuebei", "Sea mussel column" and "Chezhirou column". When choosing a Yaozhu, you can look at its size. Generally speaking, the bigger, the more expensive. According to the diameter, the size of Yaozhu can almost be five or six times different from the smallest one.

Third, choose cheats:

When buying Yaozhu, you must choose the one with complete particles, dry hand and fragrance. This kind of yaozhu is short and cylindrical, solid and full, and the meat is dry and hard. Golden yaozhu is a sign of freshness; If there is a thin layer of white powder on the surface, it will air dry for a long time. This kind of scallop is suitable for soup or porridge.

There are some fake medicine beads in the market. The main material for making fake Yaozhu is starch, but it is difficult for starch to make muscle fibers like Yaozhu, while the muscle fibers of real Yaozhu are vertical columns. If you see a "drug bead" with transverse cracks and particles, it is fake.
