Abstract
The invention discloses a removing agent for rapidly removing cadmium in shellfishes and a preparation method of the removing agent. The preparation method comprises the steps of uniformly mixing weighed vitamin C, EDTANa2, calcium chloride, chitosan and table salt, and adding the acquired mixture into water, so as to obtain the removing agent. According to the removing agent provided by the invention, the content of cadmium in the shellfishes can be effectively reduced, the removing agent is beneficial for removing cadmium in the shellfishes in shellfish production and processing enterprises and is also suitable for removing cadmium in the shellfishes bought by families, the production value of the shellfishes is increased, and meanwhile, the edible safety of shellfishes is improved. The removing agent has the advantages that the operation is easy, the removal cycle is short, and the removal rate is high.
Description
【Technical field】 [0001] The invention belongs to the technical field of food and aquatic products, and relates to a removing agent, in particular to a removing agent for rapidly removing cadmium in shellfish and a preparation method thereof. 【Background technique】 [0002] Shellfish is very popular among consumers because of its rich nutrition and health benefits. my country is rich in shellfish resources, and its output has always ranked first in the world. It is one of the leading industries in my country's mariculture. However, with the development of industries in coastal cities, seawater pollution is becoming more and more serious, and shellfish are filter-feeding organisms. Once water pollution occurs, it is difficult to avoid it. Heavy metals in water are easy to accumulate in shellfish, and human consumption of shellfish with excessive heavy metal content is likely to cause poisoning to varying degrees, endangering human health and social stability. [0003] The r...
