1. crab brain is only found in female crabs, while crab paste is only found in male crabs.

2. Crab brain and crab eggs are very close, but there is a fundamental difference between the two. First of all, the crab brain does contain egg cells that have not been discharged from the body, but there are other hairy crab organs, glands, tissue fluid and other substances, not simply crab eggs.

3. Crab paste is a collection of semen and organs from the spermathecae of male crabs, and it is also a sign of the strength and maturity of male crabs. In its natural state, crab paste is greenish-white, translucent and jelly-like. When steamed, it is translucent, sticky and a bit greasy. River crab paste slightly sweet, sea crab paste is slightly fishy, it contains water, protein, fatty acids, vitamins and other ingredients.

1. The white sticky crab paste in the male crab is the crab paste, which is the main male parasympathetic gland and its secretion, and is also the sign of the male crab's strength and maturity. Peel the shell of the male crab, you can see the crab shell and the crab lump in the middle of the white, sticky things, the natural state of the crab paste is a greenish-white semi-transparent jelly-like liquid, after steaming, for the semi-transparent, sticky gelatinous. There are two kinds of crab paste: river crab paste and sea crab paste, river crab paste is slightly sweet and sea crab paste is slightly fishy.

2. Crab paste is the male crab's parasympathetic glands, after the male crab matures, the parasympathetic glands are abnormally developed, occupying a large part of the reproductive system, and even lifting up the crab shells, so the crab paste of mature and strong male crabs is very fat. Crab paste contains a lot of essential proteins, fats, phospholipids, vitamins and other nutrients, especially fat content is the highest, which makes the crab paste has a unique flavor taste. Eat some crab paste in moderation can add the necessary nutrients for the body, but because of its total fat is too high, and high cholesterol, so people with high blood pressure or high blood fat, high cholesterol, it is best to eat less crab paste.

3. The crab brain is the ovary and digestive glands in the crab body, which means that the crab yolk is only found in female crabs. The orange-red grains in the mother crab are hard crab yolk, yellow is the liver and pancreas, we eat the crab yolk is mainly the ovaries and egg cells in the body of the mother crab.

4. crab brain is not the crab's eggs, although the composition and crab eggs are basically the same, but the two have essential differences. Crab brain does contain egg cells that have not been discharged from the body, but there are other crab organs, glands, tissue fluid and other substances, not simply crab eggs. When the volume of crab yolk becomes bigger and bright orange, the gonads of female crabs have matured, and what is discharged from the body at this time is the crab eggs, and the egg cells in the gonads in the body still belong to a part of the crab yolk.
