Dong Yuhui was persuading fans to buy less when he brought MSG last night, "I can't eat enough if I buy too much"! Hearing Dong Yuhui say this, I don't know what the manufacturer's mood is, will I think this kid is "stupid"?
I can't help but want to laugh, but the knowledge points that Dong Yuhui talked about later are what makes people admire, I think the employees of the manufacturer may not know as much as him, right?
Regarding a pack of 19.9 pieces of Lotus brand monosodium glutamate, he told so many knowledge points:
Source of MSG
Mr. Dong said that the main ingredient of monosodium glutamate is actually monosodium glutamate, which was first extracted from kelp by a person in the island country in the last century, which is why some people like to drink kelp soup, mainly because there is monosodium glutamate in it.
The reason why MSG is expensive in the first place
Since ancient times, it has been rare and expensive, and at that time, due to the limitations of production technology, the amount that could be produced was relatively small, so the price of monosodium glutamate was relatively high from the beginning.
But in many people's cognition, expensive things are good things, and good things should be expensive.
Later, with the improvement of production technology, some people found that MSG could also be extracted from wheat, and the price of MSG gradually became cheaper.
Knowledge points:
The process of starch to monosodium glutamate mainly includes:
Liquefaction saccharification - fermentation - neutralization - iron removal and decolorization - crystallization separation - drying and other steps, and finally produce monosodium glutamate, which is the crude product of monosodium glutamate.
Effects of MSG on the human body
In fact, there is no absolute, but as of now, no research has shown that MSG is harmful to the human body, but in the process of production, whether it will pollute the environment in terms of sewage treatment, this may exist.
Don't put MSG at high temperatures
In fact, about not putting MSG at high temperatures, Xiaobian also heard his parents say that when cooking, you can't put MSG when the fire is hot and the vegetables are hot, but you should put MSG when the fire is small before the pot, but the explanation I heard at that time was that doing so would be harmful to the human body.
In fact, the real reason is that when MSG is put at high temperatures, MSG will be decomposed, so it will not play a role in improving freshness.
Mr. Dong said that in addition to sweet, sour, salty and bitter taste, the other thing in the human taste is freshness. Many people have a misunderstanding that spicy is taste, but in fact, spicy is just pain, and Dong Yuhui also vividly explained why spicy is pain.
For example, after cutting chili peppers, your hands often feel pain, but when your skin is intact, you won't feel it when you touch sugar or vinegar. Does it feel bitter when you touch it? Of course not!
Mr. Dong's class is really vivid, full of dry goods! Have you learned?
