Does MSG causes cancer ?
Monosodium glutamate(MSG) is a seasoning that many people use, it can make food taste more delicious.
However, there are some people say that "MSG is a chemically synthesized product" and "heating MSG causes cancer".
The main ingredient of MSG is sodium glutamate. At present, the way to produce MSG is bacterial fermentation, which is not chemical synthesis at all.
Another saying is that when sodium glutamate in MSG is heated above 120 °C, sodium pyroglutamate may be produced, while sodium pyroglutamate is carcinogenic.
Indeed, when the substance exceeds 120 ° C, it is easy to turn into a substance - sodium pyroglutamate. But in fact, sodium pyroglutamate does not cause cancer, but there is no taste. Moreover, MSG's instructions advise everyone to put MSG after cooking.
Therefore, as long as the MSG is placed in right time, the temperature will not be very high, and you can safely eat it.
Currently, international authorities such as the US FDA, the American Medical Association, the Food and Agriculture Organization of the United Nations have conducted evaluations and reviews.No direct proof that msg causes cancer.
Many countries in the world approve monosodium glutamate to be used as a food additive. For example, the EU, Australia and New Zealand and China.
