Description
Technical field
The present invention relates to food technology field, relate to a kind of salt specifically.
Background technology
Salt is claimed dining table salt again, is to one of most important material of human survival, also is the most frequently used flavoring in the culinary art.The main chemical sodium chloride of salt (chemical formula NaCl) content in salt is 99%.
Very easily harden in the storage and transport process of common common salt when depositing and transport, thereby influence people's use.Therefore the salt that uses in the market adds the iodide except that part, also adds potassium ferrocyanide as anticaking agent, to prevent hardening of salt.
Potassium ferrocyanide, English Potassium ferrocyanide by name, formal name used at school is that three hydrations, six cyanogen close the sour potassium of iron (II), molecular formula is K
4Fe (CN)
63H
2O, molecular weight are 422.39.Potassium ferrocyanide is a pale yellow crystals, is commonly called as potassium ferrocyanide, is the complex that iron and cyanogen form, and is soluble in water, in the aqueous solution, dissociates into K
+[Fe (CN) 6] 4
-Potassium ferrocyanide is stable in the air, is heated to 70 ℃ and loses the crystallization water, decomposes behind the heat-flash.Potassium ferrocyanide is widely used in the salt manufacture field as the salt anticaking agent, and potassium ferrocyanide also can be used for making paint, printing ink, pigment, pharmacy, metal heat treatmet, food additives, steel and iron industry and rubs leather or the like in addition.
Improving constantly of Along with people's living standard; People have requirement higher to security, the trophism of the food that eaten; Salt is as a kind of most popular food flavor, nutritional agents, and its security, health are more paid close attention to, and the use of potassium ferrocyanide shows its deficiency gradually.
At first, the security in edible salt, used of potassium ferrocyanide is under suspicion.Potassium ferrocyanide can decompose behind heat-flash, produces hydrogen cyanide; It and halogen, the hydrogen peroxide generation potassium ferricyanide that reacts, its aqueous solution is met light and is then decomposited cyanide and generate iron hydroxide in air; It and watery hydrochloric acid heat altogether produce hydrogen cyanide; Potassium ferrocyanide generates cementite, cyanide, cyanogen and nitrogen when calcination.Though China has formulated strict national standard to the addition of potassium ferrocyanide, the general content of potassium ferrocyanide in sodium chloride is no more than 10mg/kg, and edible is safe.If but we in use contact high temperature or acidic materials or strong oxidizer material, potassium ferrocyanide is decomposed, emit cyanide, a small amount of cyanide gets in the body through alimentary canal for a long time, can produce chronic murder by poisoning to health.Therefore, the edible salt for adding potassium ferrocyanide has only us to guarantee correct method for using, just can be unharmful to health.And potassium ferrocyanide can dewater in the time of 100 ℃ and become white powdered anhydrous thing, so salt is in drying bed when dry, and potassium ferrocyanide is prone to dehydration and becomes white powdery by lenticular; And the proportion of potassium ferrocyanide is lower than the proportion of sodium chloride, and when drying bed reclaimed powder salt, potassium ferrocyanide can get in the powder salt more; The amount that makes powder salt contain potassium ferrocyanide surpasses 6～7 times of normal value; When these powder salts are got back in the finished product salt again, if in follow-up packaging process insufficient mixing, will make the ferrocyanide potassium content in the local finished product salt surpass 20mg/kg; Be far longer than the addition that country allows, and then harm eater's health.
Secondly, potassium ferrocyanide influences people to the part trace elements absorbed.Potassium ferrocyanide can generate sediment with most metallic element reactions; Under the situation that does not have air to exist, generating the water insoluble ferric ferrocyanide with diluted acid of white with ferrous salt precipitates; Zinc ion meeting and potassium ferrocyanide react, and the zinc ferrocyanide that generates the gluey water insoluble and diluted acid of white precipitates; Mantoquita and ferrocyanide nak response generate the iron copper cyanider deposition of indissoluble.In these reactions, though there is not the decomposition of complex compound, can not discharge hydrocyanic acid or cyanide with hypertoxicity, it will be combined into deposition with human body beneficial's element, influence the absorption of people to these elements.
Once more, potassium ferrocyanide is to the limitation of food processing with salt.China stipulates clearly that in food additives potassium ferrocyanide can be used as anti-solid agent, but in pollution-free food, does not allow to occur, and comprises that the used sodium chloride of seasoning bag must not detect potassium ferrocyanide in the pollution-free food.After in salt, adding ferrocyanide, because the existence of the ferrous cyanide ion that adds in the salt, it is difficult to obtain the approval of developed countries such as America and Europe as the security of edible additive, has limited the use of food processing with salt greatly.
Iodine is the thyroxine constituent, and thyroxine can promote the biosynthesis of protein, promotes embryo growth and development.The gestational period, thyroid function was active, and the requirement of iodine increases, and so just was prone to cause the not enough or shortage of gestational period Iodine intake, particularly had a lot of areas to belong to the iodine deficiency district in China, more was prone to cause pregnant woman's iodine deficiency.Discover that the pregnant woman takes in iodine subalimentation and possibly exist related with premature labor, stillbirth and fetal anomaly.Also have some cases to show; The pregnant woman takes in the iodine deficiency possibly cause baby's congenital hypothyroidism and neurological dysfunction, and cretinism appears in the severe patient neonate, and tired, unable, chilly, drowsiness, metabolism and the variation of circulatory function property such as interest is little are to external world arranged clinically; Skeleton development is unusual; Brain growth defective and delay, the dried flakey that forms of skin, hair, nail is unglazed, fragility etc.For pregnant woman's itself health and normal fetal development, the pregnant woman must be noted that can not iodine deficiency, especially more will note supplementing iodine at iodine deficient area.Iodized salt is a kind of economy, safety, convenience and effective methods to supply iodine.
