"Thinking about ensuring the softness of this glutinous rice product for a long time, now I basically add some appropriate additives to retain water or starch molecular structure and reduce the aging rate of starch......"

Before the fat man finished speaking, Liu Liping took on and said: "The dead fat man just doesn't have a good idea, how can additives be added to it casually, this is a big problem for people to find out!"

"Oh, that's true. Then let me ask you if Sprite is good?"

Liu Liping took a sip of the cup, nodded and said, "Of course it's delicious, I like this the most, it's refreshing with bubbles." ”

The fat man shrugged his shoulders and laughed: "Look, you are obviously a double standard, speaking of which the carbon dioxide and menthol in this Sprite are also additives, why don't you say that these are harmful?"

Liu Liping looked white, and the fat man said in a heartfelt manner: "The problem is that drinking too many drinks is harmful to health, who would drink more than normal people, isn't it harmful to add additives to this food?"

Sure enough, the woman is difficult, but the fat man soon had a new example, so he asked her: "Chicken essence and monosodium glutamate are strictly speaking food additives, why don't you say that these are harmful?"

Liu Liping looked up at the fat man, and replied with a disdainful expression: "Who said that these things are harmless, eating too much MSG will cause hair loss!"

"Eating MSG makes you lose your hair, and it seems that the monks in the temple have shiny heads because they eat MSG as a meal. The fat man complained, he also knew that this was unreliable, but this kind of clinical thing had to be explained more clearly by Xu Yi, who had learned both Chinese and Western, so he turned his gaze to Xu Yi: "The third child, you give her a lesson, tell her what the truth is!"

Xu Yi smiled and said: "The main ingredient of monosodium glutamate is called monosodium glutamate in Western medicine. In general, it is commonly used in clinical practice to cause liver failure and other causes of excessive free ammonia in the body. Various neurological symptoms appear above. Monosodium glutamate can be combined with these free ammonia to form glutamine. Mitigating the consequences of ammonia poisoning. ”

"Of course, as a medicine, there are risks in the use of both Chinese and Western medicines, and the same is true for monosodium glutamate. However, this is generally not fatal, like the average adult can limit the dosage to 23 grams per day. Of course, the infusion process must be controlled to avoid the occurrence of problems such as too fast infusion and low blood potassium. ”

"The monosodium glutamate that enters the body is basically converted into glutamine in this way. Glutamine is actually a non-essential amino acid of the human body, which can be converted into glucose, which means that it is also a substance that the human body can synthesize. As long as the content does not exceed a certain range, then the thing is harmless. ”

"The more obvious symptom of excessive glutamine accumulation in the body is that it will induce nerve inhibition and make people feel full - of course, I didn't say that eating more of this is good for weight loss, you don't tell people to buy glutamine to lose weight, too little calorie intake will cause trouble. After Xu Yi finished speaking, he added, this is too much truth not everyone understands.

The fat man smiled and said: "I remember that many health products contain glutamine, is this an indirect implication that eating more MSG is beneficial?"

Liu Liping glanced at him and said, "Cut." That doesn't prove that eating more MSG is beneficial!"

Xu Yi hurriedly stopped the conversation, and this question was clear. It's much more time-saving than the two of them continuing to lift the bar, and said with a smile: "Of course, as an additive, excessive intake of MSG is really harmful. ”

"Dead fatty, listen to Xu Yi say it's harmful!" Liu Liping smiled proudly.

"If you eat too much MSG, one of the most obvious feelings is that you feel thirsty, right?"

Seeing Liu Liping nodding, Xu Yi continued: "In fact, the reason for this is just because the sodium ions bound to monosodium glutamate are replaced by ammonia, which makes the sodium ions in the body fluid increase, which is the same as eating too much salt and pickles, which also requires drinking water to excrete sodium ions from the body." How much salt is one gram of monosodium glutamate equivalent to......" This kind of number that is not usually used, Xu Yi also couldn't remember clearly, so he paused. Before he could remember, he heard the fat man say next to him: "I know this, not counting the adulterated salt in some monosodium glutamate, pure monosodium glutamate is almost three grams equivalent to one gram of salt!"

Xu Yi also remembered that it was almost this ratio, so he smiled at the fat man and nodded, and then said: "And now it is said that eating more MSG is harmful, in fact, the main consideration is that MSG is a sodium salt. Excessive intake of monosodium glutamate is equivalent to excessive intake of sodium ions, which will also increase high blood pressure and the load on the heart and kidneys, so that if you don't eat salt, eating almost 20 grams of monosodium glutamate a day is not more than the WHO standard, and it seems that the standard of this monosodium glutamate infusion may also come from here. ”

Liu Liping still said: "It's impossible, they all say that they lose their hair by eating MSG, why don't so many people have nothing to do to spread rumors." ”

Xu Yi smiled and shook his head. "The hair loss is related to MSG, and it is likely that this is because some people lose their hair every day and eat MSG every day to get the false relationship, and then use false rumors to guide zhì. ”

"If you are a normal person, even if you don't eat MSG, you have to lose dozens or hundreds of hairs a day on average, and there is basically no obvious individual difference, only the difference between phases or noticing and noticing. ”

"In addition, in addition to this physiological hair loss, there are many people who have pathological hair loss, such as seborrheic dermatitis or something, and even because of long-term anxiety, it may also lead to hair loss. However, MSG-related hair loss, whether it is a case or a review, I have never seen it in any medical journal or literature. ”

The fat man looked at Liu Liping and said proudly: "I heard it, the conclusion that MSG is harmless is not something that has only been discovered now." ”

"As early as more than 20 years ago, the Joint Expert Committee on Food Additives formed by FAO and WHO concluded that MSG is safe to eat as a flavor enhancer based on the results of a comprehensive evaluation of various toxicological substances of MSG. Therefore, it was announced that the consumption limit of monosodium glutamate was canceled, and it was recognized as a safe and reliable food additive. ”

"Of course, considering the situation that the third child said, the intake of this monosodium glutamate must be limited, eat less to enhance the taste, and eat more to be harmful!"

Seeing that Liu Liping had nothing to say, the fat man continued: "General food additives have national safety standards, and the additives added below this standard are safe. Of course, there are problems with the management or the people who make them ignore ethics and illegally add or overuse additives. But even if it is harmful to the human body, you have to talk about a dose, aside from the dose and toxicity, you are simply playing hooligan!"

Not to be outdone, Liu Liping said: "You are a hooligan, you are a fat hooligan with no morals and no vegetarian!"

However, the fat man obviously took such a weak counterattack as a deaf ear, and continued to say to Xu Yi: "The food processing industry basically relies on adding a certain amount of hydrophilic monoglycerides such as monoglycerides lactate or monoglycerides citrate to raw materials, or adding cyclic dextrin or some maltase and the like to solve the problem of starch aging. Of course, if it is a dessert, the most common way is to add a lot of sugars to it, which can not only effectively improve aging, but also increase the flavor of the product. ”

Liu Liping listened and asked unwillingly: "That means that the cold food dumplings I often buy also have these things?"

"Of course, you can see the ingredient list, I remember I saw maltose syrup in the ingredients, which is not only to sweeten, but also to stabilize the glutinous rice flour and prevent aging. ”

Listening to this, Xu Yi couldn't help but fall into deep thought, although he was not as prejudiced against additives as Liu Liping, but considering that the amount of additives added is often not large after all, if it is usually operated, there must be a temporary negligence, if it is not toxic, it is fine, but in case the excess will cause adverse consequences, I have to consider it carefully. Like ice powder, it can't bypass the threshold of calcium ions anyway, but if there is another way for this youth group to solve this aging problem, then try not to use additives to solve it.

Xu Yi pondered and asked, "How to solve this problem in terms of catering, such as thickening." ”

"Now, one is to improve the practice to avoid this as much as possible, and the other is to use modified starch that has been chemically treated or made by other processing methods. For example, using hydroxypropyl starch to thicken those vegetables that need to be cooled completely prevents them from penetrating the water and running away, and even if you leave it all day, the sauce will be as thick as if it had just come out of the pot. ”

Having said so much, the fat man finally got to the point: "As for things like Qingtuan, zongzi and snowy moon cakes, esterified starch can generally be added to them, which can also effectively reduce the occurrence of hardening and even cracking caused by aging." ”

Xu Yi nodded, taking what the fat man said to heart. However, starch is naturally not an additive, it can only be regarded as the main material or auxiliary material, what is this modified starch, and you have to ask clearly, so he asked: "Is this modified starch an additive?"

"Of course, yes, and like my example above, the modified starch required for various food applications is different, and the amount depends on the purpose, and the addition standards in various things are also different. The fat man glanced at Xu Yi with a smile, and guessed his thoughts, and then said: "In fact, the modified starch used in the food processing industry or the catering industry has been repeatedly verified, and all of them are non-toxic and harmless to the human body." No matter what kind of modified starch is digested and metabolized in the body, it is exactly the same as normal starch, and has no effect on the human body at all. ”

"Then I'll have to look up the standards and see if I talk about it, but the general rule is that if you can't use these things, you can't use them. Xu Yi thought for a moment, and then asked: "Why don't you say that I sell this in limited quantities every day, so that as long as I can guarantee the immutability of this thing for a few hours, it should be fine, right?"
