Regarding salt anti-caking agents, it seems that they are taken out and chewed at a certain time every year.
In view of the fact that a small partner left a message about potassium ferrocyanide, Uncle Jiu decided to make a big integration of all the problems related to salt anti-caking agents. Let's take the little book and come in and take notes!
<h1 class="pgc-h-arrow-right" data-track="3" > why should table salt be added to anti-caking agents? </h1>
Table salt is added with anti-caking agents to prevent agglomeration.
Finished salt is essentially packaged and stored, and in the process, different degrees of clumping occur due to the minerals, moisture and particle size of the salt.
In order to ensure that consumers can buy salt with better liquidity, salt production enterprises will add legal anti-caking agents according to the salt varieties to avoid the occurrence of agglomeration as much as possible.
<h1 class="pgc-h-arrow-right" Data-track="3" What are the allowed anti-caking agents >? </h1>
According to the provisions of GB 2760-2014 "National Standard for Food Safety Standards for the Use of Food Additives", the additives allowed to be used as anti-caking agents in edible salt are: silicon dioxide, calcium silicate, ferric ammonium citrate, potassium ferrocyanide, sodium ferrocyanide, and iron tartaric acid.
<h1 class="pgc-h-arrow-right" data-track="3" > how do salt companies choose anti-caking agents? </h1>
What kind of anti-caking agent the enterprise chooses to use is mainly based on the difficulty, cost and effect of the process. Combining these three points, potassium ferrocyanide is currently the most frequently used and widest range of anti-caking agents.
<h1 class="pgc-h-arrow-right" Data-track="3" is potassium ferrocyanide harmful >? </h1>
Food additives are not the same as illegal additives, and foods that use additives are not the same as harmful foods.
Since potassium ferrocyanide belongs to one of the anti-caking agents allowed by the state to be added, the rumor that "table salt added to potassium ferrocyanide is toxic" is naturally not broken.
However, in order to completely dispel everyone's doubts, the necessary explanations are inevitable.
Uncle Jiu summarized several reasons for the crusade against potassium ferrocyanide on the Internet and will give analysis and answers one by one.
Is potassium ferrocyanide a chronic poison?
Potassium ferrocyanide, as an additive allowed by the state, must have undergone rigorous experimental research before giving the results of "useable", and there must be authoritative data behind it.
Whether there is a possibility of acute toxicity, chronic toxicity, teratogenicity, or carcinogenicity, it will be determined that there is no above problem before approval after some screening.
The Communist Party has led China for nearly a hundred years, and this basic trust is still necessary.
In addition, the Joint Expert Committee on Food Additives of the International Health Organization (WHO) also gave corresponding data assessment: potassium ferrocyanide should have adverse effects on human health, and its intake should reach at least 1.5mg/day, which is 150g of table salt.
If a person's salt intake reaches 150 g/ day, it is estimated that they have been killed before worrying about whether it will cause chronic poisoning.
Potassium ferrocyanide decomposes into highly toxic substances at high temperatures
The highly toxic substance that the rumor-mongers intended to produce is called potassium cyanide, and although there is only a two-word gap between it and potassium ferrocyanide, they are actually two species that cannot be beaten by eight rods.
Converting from potassium ferrocyanide to potassium cyanide is not as simple as deleting two words. Because the cyanide ions and iron in it are very strongly bonded, potassium ferrocyanide is almost non-toxic.
For potassium ferrocyanide to break down potassium cyanide, a high temperature of 400°C is required.
At home cooking temperatures, a lot of fumes rise when they reach 200°C. At 330°C, the coating of the non-stick pan will begin to melt.
I heard that foreign table salt does not add potassium ferrocyanide?
The "allowable addition" status of potassium ferrocyanide is not only established in China, but also in the United States, the European Union, Japan and other countries, and there is even no limit.
Therefore, the foreign moon does not look much better than the Chinese round murmur
