Abstract

Reinforced iodic and selenic salt is salt containing iodine and selenium intensifier, and each kilogram contains iodine 10-100 mg and selenium 3-10 mg. Because of the promotion of selenium to the absorption of body to iodine, the said salt can replenish iodine and selenium in body. In addition, selenium can ensure the normal metabolism of thyroid hormon.

Description

Reinforced iodic and selenic salt

The present invention relates to a kind of edible salt, the intensified edible salt of particularly a kind of iodine and selenium.

Iodine is the human body trace elements necessary, because the human IDD(Iodine deficiency disorders) that iodine deficiency causes more and more causes people's extensive attention, how to enrich the iodine becomes the problem of scientists study, simple and the most most economical way is that edible iodine is strengthened salt at present, because salt is the requirement that the mankind depend on for existence, people all need eat a certain amount of salt every day, make salt compounded of iodine with putting into the iodine hardening agent in the salt, really can make people from the salt of every day is taken in, obtain replenishing of a certain amount of iodine, but because iodine is not a kind of trace element that is isolated to other element and easily is absorbed by the body, make salt compounded of iodine although in salt, add a certain amount of iodine hardening agent, but when the human body selenium deficiency, still iodine can not be well absorbed, the effect that enriches the iodine can not be played even edible iodine is strengthened salt.

The objective of the invention is to: design a kind of novel salt---reinforced iodic and selenic salt that contains trace element, make human body be easy to absorb iodine and additional a certain amount of selenium element.

The novel salt that contains trace element proposed by the invention is to add a certain amount of iodine and selenium hardening agent to make and contain iodine 10----100mg in the per kilogram salt in salt, contains selenium 3----10mg.

Because above-mentioned reinforced iodic and selenic salt is to add iodine and selenium hardening agent in salt, iodine and Se content are met in the international control IDD(Iodine deficiency disorders) committee and the Chinese Soclety of Nutrition's standard to carry out, edible this salt can guarantee that human body obtains replenishing of good iodine and selenium, because selenium plays a driving role to absorbing of human body iodine, when human body under the two situations about lacking of iodine selenium, edible reinforced iodic and selenic salt not only can make the human body selenium deficiency obtain well replenishing, and selenium can promote that also the human thyroid hormone metabolism is normal, iodine is easy to be absorbed by the body, thereby reaches the purpose of supplementing iodine.Iodine deficiency spreads all over 29 provinces, cities and autonomous regions of China, and China 2/3rds above areas belong to scarce selenium district, the selenium Iodine Deficiency Area is most of overlapping, in the world, also there is selenium iodine deficiency district in some country, also must mend selenium in order to eliminate IDD(Iodine deficiency disorders) in these areas except that enriching the iodine, the simplest and the most most economical way is edible reinforced iodic and selenic salt, thereby reaches the purpose that enriches the iodine.

Specify below:

Iodine be thyroid hormone (TH) 3,5,3 ', 5 '----T4 (T ₄) and 3,5,3 '---triiodo thryonine (T ₃) the important composition composition, when the iodine insufficiency of intake, can cause TH metabolic disorder in the body, cause IDD(Iodine deficiency disorders) (IDD).

Recent study shows that selenium is necessary by human body TH metabolism.When selenium deficiency 5 of catalysis TH metabolism '----take off the iodine enzymatic activity reduce [1 type 5 '-----Tuo iodine enzyme is a kind of selenoenzyme, and selenium deficiency directly influences this enzymatic activity:, selenium has indirectly-acting to II type 5 '----takes off the iodine enzymatic activity, low selenium causes serum T ₄Raise, suppressed II type 5 '---Tuo iodine enzymatic activity], make T ₄To T ₃Conversion is obstructed.When therefore human or animal's Iodine intake was not enough, if selemium nutrition is bad, iodine deficiency can increase the weight of; If the human or animal is in the dual deficiency state of selenium iodine, enriching the iodine merely produces little effect, and when Population at risk's supplementing iodine keeps normal TH level, must consider whether the selenium supply is sufficient.

Experiment shows: the rat of selenium deficiency, and I type 5 in liver, the kidney '---Tuo iodine enzymatic activity descends 90%, blood plasma T ₄Concentration increases by 100%, and T ₃It is about 20% to descend, and shows that thus selenium has important function to thyroid hormone metabolism, in order to guarantee T ₃And T ₄Normal level promptly guarantees normal thyroid hormones level, and sufficient iodine must promptly be arranged, and sufficient selenium is arranged again, and under the two scarce situations of selenium iodine, it is not all right enriching the iodine merely.

The concrete production method of reinforced iodic and selenic salt is as follows:

The method of the method that adds sodium selenite (or sodium selenate) adding Potassiumiodate when producing salt compounded of iodine is identical.

Specific embodiment:

Adding Potassiumiodate 20mg----50mg (or KI 30mg----70mg) and sodium selenite 7mg-----11mg (or sodium selenate 8mg----12mg) have promptly made reinforced iodic and selenic salt in the example 1. per kilogram salt.

Adding Potassiumiodate 25mg and sodium selenite 11mg have promptly made reinforced iodic and selenic salt in the example 2. per kilogram salt, wherein contain iodine 15mg in the per kilogram reinforced iodic and selenic salt and contain selenium 5mg.

Adding Potassiumiodate 17mg and sodium selenate 7mg have promptly made reinforced iodic and selenic salt in the example 3. per kilogram salt, wherein contain iodine 10mg in the per kilogram reinforced iodic and selenic salt and contain selenium 3mg.

Adding KI 131mg and sodium selenite 22mg have promptly made reinforced iodic and selenic salt in the example 4. per kilogram salt, wherein contain iodine 100mg in the per kilogram reinforced iodic and selenic salt and contain selenium 10mg.

Claims

1. strengthen salt for one kind, it is characterized in that: in salt, add a certain amount of iodine and selenium hardening agent, make reinforced iodic and selenic salt, make to contain iodine 10---100mg in the per kilogram reinforced iodic and selenic salt, contain selenium 3---10mg.
