Is sea cabbage the same as wakame? What is the difference between the two
Besides kelp and nori, there are many other algae plants that people usually eat, such as sea cabbage, so is sea cabbage the same as wakame?
1. Is sea cabbage the same as wakame?
Sea cabbage is not wakame; it is a kind of algae in the class Chlorophyceae, genus Ulva, also called sea spinach, sea lettuce, etc. Wakame is a brown alga in the family Alariaceae, genus Undaria, also known as sea mustard, wakame, etc.
2. Basic introduction to sea cabbage
Sea cabbage generally lives on rocks or in rock pools in the middle and lower intertidal zones. It is relatively common in the East China Sea and South China Sea of our country, and it is an edible alga with the effects of clearing heat and detoxifying, softening hardness and dispersing nodules, and promoting diuresis and lowering blood pressure.
Sea cabbage contains a variety of nutrients, such as protein, fiber, vitamins and minerals, etc., and also contains a kind of algin and selenium, which can reduce the risk of breast cancer, coronary heart disease, and heart disease.
Sea cabbage can generally be eaten by most people, but pregnant women and those with deficiency-cold of the spleen and stomach should avoid or cautiously eat it. It has certain benefits for people with heatstroke, cervical lymph node swelling, boils, difficult urination, edema, etc.
3. Wakame
Wakame has two reproduction methods: natural reproduction and artificial cultivation. Because wakame is rich in protein, mannitol, fucoidan, highly unsaturated fatty acids, fucoxanthin, organic iodine and other elements, it is an alga with high nutritional value, so artificially cultivated wakame has also become relatively common.
There are two methods for cultivating artificial wakame seedlings:
One is low-temperature seedling cultivation. Low-temperature seedling cultivation uses the method of low-temperature cultivation of kelp seedlings to cultivate wakame seedlings, implementing sporophyte overwintering, but this method requires much equipment investment, has high costs, and is also very complicated to operate, so it is generally no longer used;
The other is normal-temperature seedling cultivation, which is simple and easy to carry out. Only a seedling room, seawater sedimentation tank, filter tank and attachment devices, etc., are needed to carry it out at normal temperature.
