The fat man frowned and said, "I think it might be like xanthan gum or carrageenan, these things can also form colloids in cold water, but I'm not familiar with these things, and I can't tell what this thing is." ”

Hearing the fat man say this, Liu Liping frowned and said: "I don't know what xanthan gum is, but this carrageenan sounds very familiar, and I always feel like I've seen it somewhere." As he spoke, he looked up at Yan Peimin, as if he wanted to find an answer on his face.

Yan Peimin looked at Liu Liping's expression and said funny: "Of course you are familiar with this thing, you also ate it yesterday." ”

Liu Liping asked him to say that he was confused, but he really couldn't remember what he had eaten yesterday, so he opened his mouth and asked, "What did we eat yesterday?"

Yan Peimin said with a smile: "Jelly." ”

Liu Liping patted her head and said with a smile: "Oh, yes, I remembered, it's written on the lid of the jelly!"

The fat man laughed: "By the way, whether it is gummies or jelly, they used to be made with gelatin, but now in order to save costs, they are basically changed to agar or carrageenan." ”

Of course, these things are basically not related to proteins except that they are similar to gelatin after being made into gels, even if the seaweed itself is rich in protein, but these proteins are also removed as impurities in the industrial processing process, and the rest is basically only polysaccharides. ”

"Isn't polysaccharides also sugar, and they can still be digested and absorbed by the human body. ”

The fat man shook his head and said, "Humans don't secrete digestive enzymes that work on these polysaccharides. Even if it is a Ganoderma lucidum polysaccharide or a Tremella fungus polysaccharide, these are sold as health products. In fact, it cannot be absorbed and utilized by the human body, and the expression of the medicinal effect of Ganoderma lucidum does not rely on this Ganoderma lucidum polysaccharide. Instead, it is called Ganoderma lucidum three ...... What's going on, third, you know?"

"You're talking about Ganoderma lucidum triterpenoids, also known as ganoderic acid. ”

"Well, that's it, I highly doubt that this so-called Ganoderma lucidum polysaccharide is the useless scraps left over after the production and purification of these things! To put it bluntly, even the jelly produced with these carrageenan and agar is the same, it is not nutritious for people at all, and none of these polysaccharides can be absorbed and utilized by the human body. Not to mention the skin, even if you eat it, it's useless. ”

Xu Yi added with a smile: "It's a bit too much to say so absolutely. These polysaccharides can be regarded as dietary fiber, which can improve intestinal peristalsis and speed up bowel movements. Xu Yi said with a smile: "However, jelly and gummies are actually not suitable for children. ”

Liu Liping asked: "Is it because the jelly was sucked into the trachea and suffocated?"

This kind of thing was more common in the early years, so now the jelly will be written on the baby under the age of three to use it with caution, but the gummies are basically not marked.

Xu Yi shook his head and said, "Not only that, in fact, these things are easy for children to chew and eat." When these are eaten in the stomach, they will not be crushed by gastrointestinal peristalsis, nor will they be broken down by digestive enzymes, and will further absorb water and expand because the digestive tract is rich in water. Strictly speaking, these things should be strictly forbidden for infants and young children. ”

"Well, it's better to have less junk food. But if it's one of these things. Thinking about it, these things are also artificially added, is this the thing that is used to attach this?" the fat man shook his head to show that he didn't understand.

"Pap" Yan Peimin clapped his hands and laughed: "Hehe." I don't know what this thing is, right? I'll give you a hint, the fat man's guess is quite reliable this time. At least half of the guess was correct. ”

The fat man said in surprise: "Why, fourth brother, do you know what this thing is?"

Yan Peimin nodded and said with a smile: "Yes, I knew what it was when I saw the people in their bedroom sticking this thing, and I also knew that this thing really has nothing to do with collagen." ”

"Then you still let her buy it. ”

Yan Peimin said with a smile: "People will not be demolished." ”

"Who won't dismantle it?" Xu Yi asked.

The fat man smiled and said, "Life is already very difficult, so don't take it lightly." ”

Liu Liping stretched out her hand and grabbed Yan Peimin's neck, and said viciously, "Yan Peimin, I'll strangle you bastard, I really think our family's money was picked up for nothing, you don't say it if you know it's useless!"

"I don't have much to say, this thing is good for your pimple. Liu Liping naturally just pretended to be loud and shouted very loudly, but in fact, it was just a show, Yan Peimin casually broke away, glanced at Liu Liping and said with a smile: "Do you really want to know what this thing is? Actually, we learned this when we were in Chinese medicine class, but you may not have thought that this thing is." ”

"I don't know. ”

Several people shook their heads one after another to say they didn't know, even Liu Liping shook their heads, "Why don't I know what this is." ”

"Whipping the hydrangea, or the blue flower fairy. ”

Xu Yi was the first to react, this is a local medicinal material, and there are only a few words mentioned in the book, and he only learned more about it when he was reading books in the library. "You say this is fake sourdough?"

Yan Peimin smiled, this is this thing, in fact, this thing is called ice powder seeds in my house." ”

"Where did that name come from?"

"I'll sell it first, and I'll talk about this thing later. Saying that, Yan Peimin said with a smile: "Actually, this layer of transparent things, this ingredient fat man guessed almost, this is indeed a polysaccharide, but it is not carrageenan or xanthan gum, and this layer of things is not added, it is something that comes with this kind of sub." ”

The fat man picked up the unopened package of masks and looked at them, and asked, "It's amazing to stick together after soaking it in water!"

"Yes, in fact, this thing is a nightshade plant, in fact, we can often see this situation, but you don't think about it. Tomatoes from the same Solanaceae family, haven't you noticed that cherry tomatoes and vegetable tomatoes are covered with a transparent, slippery layer on the outside, of course, this thing is not unique to Solanaceae, and even seeds like cucumbers have these things on the outside. ”

Xu Yi said with a smile: "You said I remembered, every year when I keep tomato seeds or cucumber seeds at home, I have to wash off this layer of film, otherwise this kind of seed will not germinate! ”

Yan Peimin nodded and said, "Actually, after I went to college, I remembered to look for the information myself." In fact, these are the pectins that play a role in nutrition and protection outside the seeds, and the pectin is divided into high-ester pectin and low-ester pectin. ”

"Low-ester pectin plus divalent metal ions, this can form a gel, and can even absorb water equivalent to hundreds of times its own weight, far stronger than gelatin's water retention performance, so this thing is also used in cosmetics, as well as in fruit drinks. ”

Saying that, Yan Peimin looked up at Yu Hangsheng and said with a smile: "And there is a thing that is more common in summer that also contains this thing, guess what?"

Several people shook their heads, indicating that they did not know.

Yan Peimin said with a smile: "Let me give you a hint, a snack that fat people must eat in summer." ”

The fat man stretched out his finger and pointed to his nose and asked, "Me, is it a cold drink?"

Yan Peimin shook his head with a smile: "It's turtle jelly." In fact, that thing is made by boiling water with fairy grass and rice milk, in fact, if there is no turtle plate and poria cocos, this thing is also useless. But just like the fat man said before, we can't just focus on nutrition when we eat, this is a process of enjoyment. He looked at the fat man and said: "Actually, the fat man just can't imagine that there is a kind of thing that our canteen always makes, but the main ingredient is also low-ester pectin." ”

Yu Hangsheng asked, "What is it?"

"It's the konjac tofu that we always fry with snow cabbage here, this thing is made of pectin extracted from konjac, and it has nothing to do with tofu at all, this dish is really a taste, high salt and no nutrition!"

"Well, I really don't know, I thought it was rice flour tofu. ”

"In fact, in addition to this, there is also a traditional Chinese medicine that is also commonly used to extract this low-ester pectin as a snack. ”

"What's that?"

"Xue Li, like Liangguang and Taiwan Province, are accustomed to using Xue Li to make cold powder, and even Taiwan Province still calls this Ai Yubing. ”

Xu Yi nodded and said, "You said this, I remembered, this lychee fruit also has a name called Liangfen fruit." But you know why you are still messing around with her, even if this fake sour pulp has a sterilizing effect, it is also to be boiled and dissolved together with the fat to work, so what can the blister do? ”

Yan Peimin said with a smile: "Hehe, I was thinking that it would be harmless anyway, after all, I also know something like what you said, but you can't let me tell her directly, this is careful, I want to say that she must not be angry with me." ”

The fat man remembered what Yan Peimin said before, and asked, "Fourth, why is this thing called ice powder seeds?"

Yan Peimin said: "When it comes to this name, you have to talk about a snack in my house. When I was a child, we were already very popular to sell a snack called ice powder, which looked like a relatively thin transparent jelly, scooped into a bowl and mixed with brown sugar, it looked like crushed ice cubes mixed in brown sugar water, so it was called ice powder. As he spoke, Yan Peimin compared his hand. "Such a big bowl, when I was a child, almost only one dollar a piece, this was my favorite when I was a child. Add to that the smell, and I know it as soon as I smell it. However, there are very few handmade ice powders like when I was a child, and there are pectin extracts with konjac gum or carrageenan and other ice powder powders made with flavors sold everywhere on the Internet, which is strictly speaking, similar to homemade jelly, and of course there is no such pure taste. ”

As he spoke, Yan Peimin got up and turned his head to ask Liu Liping: "What about the things we bought before?" (to be continued......)
