What are the safety problems of marine food?

China's marine food sales are expanding from the traditional coastal areas to the mainland market, which is followed by many problems. First of all, there are safety problems in the marine food industry related to the food industry. Marine food itself is green food, pollution-free, safe and nutritious, but in recent years, the safety problems of marine food are common. On the one hand, it is the problem of food safety monitoring in the process of marine food production and processing, on the other hand, it is the emergency around the ocean. For example, the Dalian oil pipeline explosion occurred in July.

It is understood that the severity of marine pollution directly affects the quality of seawater, and the quality of seawater and marine food interact with each other. The seawater quality is good, the pollution index is low, and the marine food is relatively healthy and safe. One-sided exploitation of marine resources for profit can only harm others and themselves. Taking algae as an example, marine food developed and processed by algae is a typical representative of blue food. Seaweed food contains protein, less fat and 18 amino acids, including 8 amino acids, 1 1 trace elements and 9 vitamins. Has the effects of strengthening body constitution, promoting digestion, enhancing immunity and beauty beauty. Algae polysaccharide has anti-tumor and anti-AIDS functions, and can improve the oil secretion of skin and hair if eaten regularly. In addition, seaweed can selectively remove carcinogens of heavy metals, such as mercury, cadmium and lead. If algae live in a polluted environment, they will accumulate heavy metal ions in the ocean through main branches and passive sucking. When heavy metal ions reach a certain concentration in algae, they will have toxic effects and endanger human health after eating.

Porphyra kimbap is a leisure marine food processed by seaweed in China and the originator of seaweed processing in Chinese mainland. Its seaweed is processed from Porphyra yezoensis extracted from the pure sea area of 33 degrees deep sea, which ensures the edible safety of seaweed from the source.

Secondly, marine food processing is in the primary stage. According to the statistics of sales data, about 50% of marine food is frozen at present. How to deeply develop marine resources is still a technical problem. As we all know, the extraction technology of anticancer active substances from seaweed represents the deep utilization of marine biological resources, and is gradually being applied to the research field of human physiology and pharmacology, which will play an epoch-making role in the prevention of human cancer.
