First of all, it depends on the size of Yaozhu. Generally speaking, the bigger the head, the more expensive it is. According to the diameter, the difference between the maximum and minimum can be almost 5 or 6 times.

Second, look at the color. The surface of Yaozhu is golden yellow. If it is broken, it is a sign of freshness. If there is a thin layer of white powdery attachment on the surface, it will air dry for a long time. This kind of yaozhu can be used to make soup and porridge, but it will taste worse if it is used for cooking.

The other is the taste and weight. The quality of Yaozhu has a very fresh seafood flavor. If you tear a small strip and put it in your mouth, you can obviously feel the pure seafood flavor. In principle, it is better to choose the same volume of dried food, and the heavier one contains some water, but compared with weighing scale, you must choose complete granules when buying;

Finally, how to save it? It's best to put it in a sealed fresh-keeping box, put it in the refrigerator when necessary, and carry it with you.
