The crab yolk of the pike crab is orange and powdery. Crab yolk refers to the ovary and digestive gland in the female crab, which contains egg cells that have not yet been discharged from the body. Crab paste refers to the parasympathetic gland of the male crab and its secretion, which is generally a greenish-white semi-transparent jelly-like liquid. The reasons for the bitter crab roe: 1) the crab is not fully mature, the crab roe is not fat enough; 2) the resting time is not enough, the food residue in the body is not clean; 3) the quality of the breeding water is poor, and the crab is infected with disease; 4) the crab is not enough for the food residue in the body, the food residue in the body is not clean.

First, what does the crab yolk of the pike crab look like

1, the crab yolk of the pike crab is orange, powdery, like the yolk of a salted duck egg.

2, the crab yolk refers to the ovaries and digestive glands in the female crab, which contains egg cells that have not yet been discharged from the body, with a high content of oil and cholesterol. The crab paste refers to the male crab's parasympathetic gland and its secretion, generally greenish-white translucent jelly-like liquid, rich in protein, lipids, and other types of nutrients (river crab paste is slightly sweet, sea crab paste slightly fishy).

3, around the ninth month of the lunar calendar, the female crabs in the body of the crab yolk is the most abundant, and around the tenth month of the lunar calendar, the male crabs taste delicious, full of crab paste.

4, pike crab selection method: if the crab shell is green, hard texture, full and heavy abdomen, lines clearly visible, clear lines, the side is more broad and thick, the crab legs are hard, feel heavy, indicating that the pike crab is more plump. If the crab shell is yellow, smooth abdominal lines, narrower side, lighter in the hand, it means that the pike crab is thinner.

Second, why is the crab yolk bitter

1, the crab is not yet fully mature. Normal crab yolk is golden yellow, usually in the lunar calendar around September when the most full of fat, and the development of the crab has not yet fully developed crab yolk color for the greenish light color, and more thin, not lumps.

2. Insufficient resting time. The middle of the crab yolk is the crab's stomach, and there is residual food in the crab's stomach (bitter water plants and algae), if the resting time is not enough, the food residue can not be completely discharged from the body, and in the process of cooking, the bitterness of the pigment will diffuse to the crab yolk, resulting in the crab yolk with a bitter taste. Generally, it needs to rest in the water for about 2 days to get rid of the residual food residue in the body.

3, the breeding of poor water quality, the body of the drug residue is more, the crab infected with disease, etc. will lead to the crab with a bitter flavor.
