Can MSG cause cancer? Market regulation tells you the answer

Once upon a time, MSG was one of the essential condiments for home cooking
, along with salt and soy sauce.
But I don't know when it started, there was endless controversy about MSG, "MSG is a chemical synthetic product, carcinogenic", "MSG is toxic after heating".
.
.
Some people choose to eat less or no MSG
.
So, is MSG really as rumored? On November 15, the Jiangxi Provincial Market Supervision Bureau issued a consumption reminder
.

What is MSG?

The National Standard for Food Safety MSG (GB 2720-2015) stipulates that monosodium glutamate is a white crystalline or powdered condiment with special umami flavor made by fermentation, extraction, neutralization, crystallization, separation and drying of microorganisms (Corynebacterium glutamate, etc
.
) as raw materials.

From the process, it can be seen that monosodium glutamate is not a chemical synthetic product, but is made of grain as raw material by fermentation and purification, and the manufacturing process of rice wine and aged vinegar is similar, and its own safety substance
.

The main component of monosodium glutamate is sodium glutamate, and the "Standard for the Use of Food Additives" (GB2760-2014) stipulates that sodium glutamate is a flavor enhancer
that can be used in various foods according to the needs of production.

Does MSG produce carcinogens when heated?

People believe that "delicate taste cancer" is mainly due to social rumors that "sodium pyroglutamate produced after heating monosodium glutamate is harmful to the human body
".
Studies have shown that MSG heated to more than 120 ° C and maintained for a long time may produce sodium pyroglutamate, but this substance is not carcinogenic and does not affect
human health.
Long-term high temperature to generate sodium pyroglutamate, but will make MSG lose umami, affecting the freshness effect, so, some product introductions will prompt "put MSG before out of the pot"
.

Which is better, MSG or chicken essence?

Under the guidance of public opinion that "MSG is unhealthy", consumers have turned to "healthier" chicken essence
.
But in fact, as a compound condiment, one of the main components of chicken essence is monosodium glutamate (sodium glutamate), but additional food additives such as salt, sugar, and nucleotides are added to make the effect of freshness more obvious
.
Therefore, there is no question of who is healthier than whom, and consumers can
eat it in moderation according to their needs.

The correct way to open MSG

Add
in moderation.
MSG has high freshness, and a small amount of addition can achieve the freshening effect
.

Avoid high temperatures
.
When cooking, it is best to add MSG before cooking, MSG heating over 120 °C for a long time will generate sodium pyroglutamate without umami, which will affect the freshness effect
.

Balance MSG and salt intake
.
The Dietary Guidelines for Chinese Residents 2022 recommend "a light diet, eat less high-salt foods, and adults should consume no more than 5 g of salt per day; The reference intake for macronutrient sodium ions is 1.
5 g/day"
.
The sodium glutamate in monosodium glutamate contains sodium and has a high sodium content, consumers should adjust the amount of salt and monosodium glutamate according to their own taste to avoid excessive intake of sodium ions to induce cardiovascular and cerebrovascular diseases
.

Special people should eat
with caution.
Patients with kidney disease and high blood pressure should try to eat less or no monosodium glutamate
.
