How to eat Antarctic krill

There are only a handful of people in China who have eaten Antarctic krill, and researcher Huang Hongliang is one of them. He traveled far into the ice and icebergs with China's 22nd Antarctic expedition team, and used self-developed survey fishing gear to pick up several kilograms of krill, peel them and eat them raw. The reporter learned from the East China Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences that experts from the institute discovered through multiple polar scientific expeditions that the medical value of Antarctic krill may be better than its edible value. It can clear wounds and can also be made into a tonic to prevent "three highs". ”, this Antarctic specialty is approaching the lives of Chinese people.

With a green head, black eyes, bright red body, fresh taste, and 8 kinds of amino acids necessary for the human body, this is the single species of marine life with the largest reserves and the most successful reproduction on the earth - Antarctica. Krill. The World Health Organization evaluated the comprehensive nutritional value of its amino acids. As a result, krill scored 100 points, beef 96 points, milk 91 points, and shrimp 71 points. Scientists pay more attention to its unsaturated fatty acid content of up to 70%, especially because it is rich in "omega-3" fatty acids that mammals cannot synthesize by themselves.

It is understood that domestic biotechnology companies are currently developing krill medical preparations, including research on the callus function of krill enzyme. According to reports, "krill enzyme" preparations have been used abroad to treat malignant leg tissue ulcers. Using physiological saline as a reference, the wound clearance rate after 7 days was significantly better than that of the control group, and no side effects were found. In another 72-hour in vitro test of skin tissue degradation, a comparison of krillase, papain, fibrinolysin/nuclease, etc. showed that krillase preparations have the best effect among these biological agents.

Antarctic krill is also valuable in daily necessities. Krill contains more than 6 kinds of proteases, and the cleaning effect of detergents made from them is better than that of enzyme-added laundry detergent; krill contains ultraviolet shielding substances, and a "krill sunscreen" may appear in cosmetics in the future.

At present, Russia, Japan, South Korea, the United States and other countries are already engaged in krill production. They plan to catch 245,000 tons this year, and the exploration of krill treasures is in the ascendant. The East China Sea Fisheries Research Institute has sent 11 people to Antarctica eight times to conduct preliminary scientific research and prepare necessary technical reserves for the comprehensive development of this resource.
