Embodiment

[0012] A method for removing arsenic from hijiki, comprising the following steps:

[0013] (1) Rinse hijiki with water, put it into 0.6mol / L citric acid solution, keep the temperature at 60-70°C, keep the rotation speed at 100 rpm, and stir for 2-3 hours;

[0014] (2) Take it out, rinse it with water and cool it, then put it into 1.5mol / L acetic acid solution, keep the temperature at 50-60°C, keep the speed at 60 rpm, and stir for 3-4 hours;

[0015] (3) Put the hijiki obtained in step (2) into 0.62mol / L hydrogen peroxide solution, keep the temperature at 30-35°C, soak for 40-60 minutes, take it out, wash it with water, drain it and put it in 50- Dry at 60°C for 10-12 hours.

[0016] Use the method in this example to conduct arsenic removal experiments on three equal amounts of hijiki from different sea areas, namely Weihai in Shandong, Zhoushan in Zhejiang and Putian in Fujian, respectively, and detect the inorganic arsenic content before and after the removal of arsenic , ...

Abstract

The present invention discloses a hizikia fusifarme arsenic removing method which includes the following several steps: inorganic arsenic leaching out by using citric acid solution to conduct stirringat 100 rpm, inorganic arsenic leaching out by using acetic acid solution to conduct stirring at 60 rpm, soaking using hydrogen peroxide, and drying. Compared with the prior art, the hizikia fusifarmearsenic removing method has the following advantages: the operating conditions are easily controlled; the inorganic arsenic content is lowered to about 0.1 mg / kg through several effective leaching ofinorganic arsenic in the hizikia fusifarme, which achieves the standard level of food safety. At the same time, due to mechanized continuous operation, the entering of other substances affecting thefood safety can be effectively avoided to ensure the hizikia fusifarme to be developed and utilized safely.

Description

technical field [0001] The invention belongs to the technical field of deep processing of agricultural breeding, and in particular relates to a method for removing arsenic from hijiki. Background technique [0002] Hijiki is a precious marine algae plant, which is recorded in many Chinese pharmacopoeias and has been used as a medicine so far. Its use and medicinal value have attracted more and more attention. Hijiki is rich in polysaccharides and dietary fiber Vitamins, B vitamins, alginic acid, mannitol, and essential minerals and trace elements for the human body. Hijiki is a warm-water perennial seaweed that is naturally distributed on the west coast of the Pacific Ocean. It is widely distributed in China from Dalian in the north to Hainan Island in the south. , especially in Zhejiang and Fujian and other regions. With the development of economy, more and more people can bring healthy diet to people. Sargassum usually grows in seawater, and the arsenic content in seawater...
