The reasons for the bitter taste of crab roe are: immaturity, inadequate preparation before cooking, deterioration, poor water quality, sick crabs and so on.

1, immature

Crab yolk is the product of female crab. If the mother crab is eaten before maturity, the crab yellow may be bitter.

2. Insufficient preparation before cooking

If you don't prepare enough before cooking crabs, the boiled crab roe will be bitter. Therefore, you can soak the bought crabs in clear water for a few days, and then you can cook them after the crabs spit out the dirty things.

Step 3 worsen

The crab died before it was eaten. In the case of crab death, a large number of bacteria and other microorganisms will breed in the body, which will lead to crab roe deterioration and bitterness.

4. Poor water quality

Poor water quality makes the cultured crabs seriously polluted, and the waters where crabs live are polluted. Their bodies will contain harmful substances such as heavy metals, so many harmful substances enter the crabs, making them yellow and bitter.

5. Sick crabs

If the crabs bought are already ill, the cooked crabs taste bitter, so you need to be careful when buying crabs. If you find taupe spots on crab shells, don't buy them.
