Precautions:
1, buy less and eat in time
Buy a small amount, and then buy it after eating to prevent iodine from sublimating. Because potassium iodate will decompose and volatilize under the conditions of heat, light, wind and humidity.
2. Avoid high temperature
Avoid putting iodized salt at high temperature when cooking soup. The edible rate of iodized salt is only 10% in stir-frying and stir-frying, 60% in the middle, 90% in stir-frying and 100% in cold dishes.
3. Avoid prolonged exposure to containers.
Iodized salt is easy to volatilize if it is exposed to sunlight and air for a long time. It is best to put it in a colored glass bottle and seal it tightly with the back cover.
Extended data
According to whether iodine is added, salt can be divided into iodized salt and non-iodized salt. The iodine content in drinking water in most parts of China is low, which once led to high incidence of iodine deficiency diseases such as goiter (commonly known as "big neck disease"). In order to actively prevent and control it, China adopted the measures of iodizing salt in 1995, and artificially added potassium iodate, potassium iodide or seaweed iodine. The iodine content is generally 2 1~33 mg/kg, which is suitable for most people to eat.
Among them, seaweed iodine is a new generation of iodine supplements made from seaweed, and its absorption rate is better than that of potassium iodate and potassium iodide. Patients with hyperthyroidism and some thyroid cancers need to take non-iodized salt according to the doctor's advice.
The researchers found that iodine deficiency is a risk factor for thyroid nodules, and the increased prevalence of thyroid nodules may be related to the increased screening opportunities. Consumers should treat iodized salt rationally, especially pregnant women and lactating women with high demand for iodine. If they don't eat seafood often, it is wise to take iodized salt every day, otherwise it may bring irreparable influence on children's intellectual development.
