Method for cultivating novel edible seaweed rich in organic selenium

Abstract

The invention relates to a method for cultivating a novel edible seaweed rich in organic selenium, which is characterized by comprising the steps: adding mother cultivation liquor into a cultivation pond, and adding salt containing selenium into seawater serving as mother liquor so that the mother liquor becomes the cultivation liquor with the selenium content of 1-990 mg / L; then, cultivating the seaweed in the cultivation pond, wherein the weight ratio of the added seaweed to the mother liquor is 1:15; and storing the seaweed after cultivation is finished. The method for cultivating the novel edible seaweed rich in organic selenium, provided by the invention, can enable the seaweed to contain rich organic selenium, and the content of organic selenium can not be too high to influence the health of crowds.

Description

technical field [0001] The invention relates to aquaculture of seafood, in particular to a novel method for aquaculture of edible seaweed rich in organic selenium. Background technique [0002] At present, people are very fond of marine biological food. Among them, due to the characteristics of eating seaweed itself, it contains many macro and trace elements that are beneficial to the human body, so it is favored by the crowd. However, due to various conditions, the content of trace elements is low, and selenium deficiency has adverse effects on human metabolism: sensitivity to certain oxidative damage and changes in thyroid hormone metabolism, increased sensitivity to mercury damage , changes in the activity of biotransformation enzymes, and an increase in plasma GSH concentration, it is generally believed that selenium plays a role through selenoproteins. The low selenium state of the human body and the nutritional status of selenium are related to arthritis, cancer, card...

Problems solved by technology

a. Too high selenium content: such as selenium-enriched yeast, the selenium content reaches 700-1000mg / kg, such a high selenium content makes it unable to have food attributes; b. Too low selenium content: such as selenium-enriched fruits, The selenium content of vegetables and other selenium is very low, and the general consumption is difficult to achieve health effects; c. The form of the selenium element is not clear: the substances containing inorganic selenium can be eaten directly as food or indirectly as food additives. Because of the certain toxicity of selenium, this method of supplementing selenium has certain dangers or produces adverse consequences.

All kinds of selenium enrichment methods introduce selenium into the object through adsorption, only a part of which is converted into an organic state, and the rest remains in an inorganic state, so the application of selenium supplementation is greatly limited
