Embodiment 1

[0023] ① 500kg of dried kelp, cut to about 5cm long by a vegetable cutter; add the alcohol solution soaked twice in the previous extraction tank, and then add 2000kg of alcohol with a volume concentration of 60%; put in kelp, stir for 1 minute, Heat to 70°C and soak for 30 minutes, then stir and soak in the same way for a total of 90 minutes of kimchi; put the extract for purification treatment; add 1000kg of alcohol with a volume concentration of 60% to the dried kelp, stir for 1 minute, After static soaking for 15 minutes, stir in the same way, static soaking, pickle vegetables for 30 minutes in total, put alcohol solution, and use it for soaking dried kelp next time; the soaked kelp is used to extract alginate.

[0024] ② Separate and purify the obtained alcohol extract with a decanter centrifuge to obtain a clear liquid and drain the residue.

[0025] ③Heat the separated supernatant to 70°C, add alginate with a weight ratio of 0.4%, fully stir and mix, keep it warm, and ke...

Abstract

The invention provides a method for extracting iodine from kelp by comprehensively utilizing brown algae, and can solve the problems in the prior art that heavy metal is remained in the iodine from kelp. The invention adopts the brown algae as raw materials to prepare the iodine from kelp; in an extraction process, a principle that alginate from the brown algae absorbs the heavy metal is utilized, so as to solve the residue problem of the heavy metal in the iodine from kelp during the physical extraction process; and on the premise of ensuring the content of the iodine from kelp, the active ingredients of the kelp are remained to the maximum. At the same time of extracting the iodine from kelp, algae fine oil, algin and mannite are extracted by comprehensive utilization, so that the utilization rate of the kelp is increased to the maximum.

Description

technical field [0001] The invention relates to a preparation method for extracting seaweed iodine through comprehensive utilization of brown algae. Background technique [0002] Iodine is an essential element for the human body. Governments all over the world attach great importance to the iodine supplementation of their citizens. In order to eliminate the threat of iodine deficiency diseases to the health of the people, improve the quality of the people, and suppress the harm caused by iodine deficiency diseases, my country implements compulsory iodization of table salt. With the continuous deepening and development of my country's salt iodization project, the iodine deficiency The disease has been effectively controlled and the health of residents has been greatly improved. Under the new health concept, people have a higher demand for iodine supplementation with salt, not only iodine supplementation but also scientific iodine supplementation. Potassium iodate is added t...
