"I'll find it for you. With that, Yan Peimin bent down, took out the bag in the box, and threw it to Xu Yi. "The newly hatched fish don't need to be fed for three or four days at first, and when they can eat, they can feed this, and they can be fed for more than ten days, and then they can be fed with feed. ”

Xu Yi reached out and grabbed the small bag that flew over and asked, "What is this?"

Yan Peimin straightened up, stretched his waist, and said, "Brewer's yeast." ”

"What is brewer's yeast, is it the yeast used to brew beer?" Xu Yi asked curiously.

"Where do I know, I got this thing from the scientific research base, and people told me to use it like this, where did I get so much curiosity, I guess, this thing is probably the yeast used to brew beer." Yan Peimin smiled bitterly, Xu Yi really didn't know this question.

Yu Hangsheng, who was originally lying on the bed and watching the two of them busy, heard Yan Peimin say this, burst out laughing, stretched out his chubby fingers and hooked them towards the two people and said, "Uh-huh, the third child's question has a certain depth and a certain academicity, two nerds, do you need me to give you a science popularization?"

"Then you say, I'd like to see how deep this thing is. "This fish egg is fine, just wait for it to hatch, so Yan Peimin was in a good mood, and he followed the fat man's words and said, this dead fat man, usually has a rare opportunity to show off, after all, there are a few people in the dormitory, the boss is diligent enough, and he is basically not in the dormitory at night when he enters the senior year, the third child is better than his own study, and he is the master who gets a first-class scholarship every year, even if he is busy taking the graduate school examination, where does he have time to listen to him brag.

Hearing that Yan Peimin was interested, the fat man sat up with his arms propped up, and said: "I won't talk about the general properties of yeast, anyway, you are all scholars, this thing was explained in the time of microorganisms, so I'll talk about what is not in our book." ”

"It's all heresy. Yan Peimin pursed his lips and made a disdainful look, if no one accosted him, this fat man would not be able to continue.

"I just think it, the power of this example is infinite, the two of you are becoming more and more husband and wife, this temper is becoming more and more similar" The fat man laughed at Yan Peimin and the two of them, and then said: "I will only talk about the two yeasts commonly used in the food industry now......"

Yan Peimin immediately heard the voiceover here, looked at Yu Hangsheng with a smile, and asked: "Fatty, this is not your style, you are timid." It's not that you only know two kinds of yeast, right? According to your style, you need to know ten kinds, and you will definitely not only name two, not to mention that if you are a foodie, you must be playing tricks when you talk about any industry. ”

Yu Hangsheng didn't have a trace of embarrassment to be exposed, and still laughed: "So what, at least I know what this thing is in your hand." ”

"Then you say, what is this?" Xu Yi raised the bag in his hand.

The fat man glanced at the bag in Xu Yi's hand, saw the trademark on it, and said with certainty: "When it comes to the yeast commonly used in the food industry, the most common one is brewer's yeast. ”

Liu Liping was reading a book, but when she heard it, she raised her head and complained: "What is the yeast underneath, and the yeast above." ”

The fat man smiled hesitantly and glanced at Liu Liping complacently. "Yes, yes, there's the yeast above. ”

Not to be outdone, Liu Liping grimaced, and then gave the fat man a sanitary eye. "What's the matter, no matter what, it's as round as you, dead fat. ”

The fat man ignored it, and continued: "This thing of yours is made from fermented beer puree in the brewery, which is just a product of waste reuse." ”

Xu Yi looked at the bag in his hand suspiciously, and then looked at the fat man suspiciously: "It says: Brewer's yeast, also known as nutritional yeast, is taken from a bitter plant that can be used as an ingredient in beer, hop seeds, and it is not beer puree at all, are you breaking it blindly?"

"Do you know what hops are?" Yu Hangsheng looked at Xu Yi with a smirk.

Xu Yi shook his head, "I don't know, I know castor, gastrodia, toad, and flax, but I don't know what this hop is, it says it's a herb, why don't I have any impression at all?"

The fat man saw Xu Yi deflated, his heart was dark, and he said with a smile: "What's the matter, there are also things that you don't know as a scholar, what about you, the fourth, I guess not to mention, you might as well be the third well-read." ”

Yan Peimin also took a packet of yeast, studied it, shook his head and said: "This is written as a medicinal herb, but I don't have any impression at all, where do I know what it is, it can't be scribbled on it, right?"

The fat man raised his chubby index finger and shook it twice, "Hehe, who told you that this is not a medicinal herb, and the extract of hops can cure leprosy." ”

"Oh, I don't know. ”

Xu Yi was stunned when he heard this, and said: "Hey, I seem to have a vague impression of this, as if I have seen it in some medical book, what extract can treat leprosy." But as you know, our province is not a leprosy epidemic area in the first place, so I don't remember much about it. ”

The fat man glanced at Yan Peimin and said, "Hehe, look, I'll just say that the third child is better than you, at least he can have a little impression." ”

Yan Peimin snorted, nonsense, where can I have Xu Yi to study well, and even if people don't go home for internships, they will soak in the library all day long to read, if it weren't for economic factors, why would they want to push it off if it weren't for the economic factors? "Less nonsense, hurry up, sell less!"

Before the internship mobilization meeting in September last year, after the head teacher read out the results of each person in the previous semester, he took a recommendation form for graduate school exemption to Xu Yi, who gave up very resolutely at that time.

Yan Peimin, who took the postgraduate entrance examination as his responsibility in the same dormitory, was envious and jealous to death, claiming that he didn't have such a good thing, and he still had to take the exam, and he might not have passed the exam, passed the theory exam, and may not have passed the interview......

At that time, the whole class was in an uproar, and the head teacher didn't understand, but Xu Yi just smiled and didn't say anything at that time, and went back to the dormitory, Xu Yi explained the reason to a few people, and everyone also expressed their understanding, after all, economic conditions like Xu Yi are indeed not suitable for continuing to study, so I am afraid that the cost will be too high, after all, he made up his mind to go back to his hometown to work, and it is not very meaningful to study for a graduate school, it is more practical to graduate early.

The fat man said slowly: "Because this thing is not a Chinese thing in the first place, this is an unstructured European herbal medicine, and Europeans used this as a herbal medicine before the Middle Ages." It has a history of less than 100 years in China, which has been studied a lot in recent decades, and it can be regarded as a foreign use. ”

The two of them nodded, Xu Yi couldn't help but remember, this alien species is often called by a lot of names, and even if it is a native plant, I am afraid that there are different names in different places, and even the herbs have many medicines and dozens of names, and asked: "Then does this thing have any other names?"

The fat man squinted his eyes to uncover the mystery: "Actually, this thing is hops, you've always heard of it, right? This is the source of the bitter taste of beer, of course, some pastries also like to add some of this." ”

Hearing the fat man say this, Xu Yi suddenly said: "It's the hops that brew beer, oh, I remember, when I first read the book, I saw this name, but there is no sample in the book, and I don't know what it looks like." ”

Yan Peimin listened, but he was reasonable, "Isn't that enough, since this thing is added to beer, people are not wrong." ”

The fat man smiled and said, "Hops are dioecious plants, and they are used to make wine or bread with the inflorescences of female flowers, not seeds at all, otherwise this thing is not called hops, it should be renamed beer seeds." Therefore, the things marked on it are simply nonsense and non-existent, and they can be determined to be false propaganda. ”

"Then there are at least hops here, right?" asked Xu Yi.

"Third child, I know you drink tea, do you still eat the tea after you drink it?"

"It's tasteless, why am I eating that?"

"What disappoints you is that the average distillery only adds two or three catties of hops to a ton of beer, which is worse than the chicken essence I said yesterday, this is the seasoning package after marinating the spicy hot eight hundred times, how much of this thing do you think can be in this beer puree, and how many nutrients can be left?"

"But what is beer puree?" Xu Yi asked, feeling quite helpless in his heart, this propaganda is also a bit too fake.

"Spit a word, this beer puree is a good saying, generally we call the residue left over from the brewing are called sake lees, people used to feed pigs, and now the merchants dry it casually, and then crush the packaging to sell, but this can not change the essence of its pig feed. ”

Yan Peimin himself looked at the nutritious thing written on it, he used to be hungry at night, and he rushed to drink this thing, but now listening to the fat man say this, he can't help but feel that his throat is itchy, "I'll ...... it."

The fat man looked at Yan Peimin's devastated appearance, and then said: "Of course, the brewery crushes wheat or something, and then adds yeast to ferment, and this thing in your hand is the residue left after the saccharification liquid is fermented mixed with a large amount of yeast or the remains of yeast that died during the fermentation process, do you say this is sake lees?"

Xu Yi was also speechless, this is naturally sake lees, seeing that this packaging is so exquisite, the price must not be too cheap.

Xu Yi couldn't help but admire the copywriting skills of this manufacturer, but it was just a wine lees, which could make them blow to the sky, as if this thing was a rare and precious item in the sky and on the earth.

Obviously, the fat man looked at Yan Peimin's expression, and knew in his heart why this person had a dead face, and secretly laughed in his heart that this person really didn't resist the blow, and he didn't plan to let go of this bag at all, and then complained: "There is another thing that will make you completely desperate - now large breweries don't use hops at all, they are all artificially synthesized hupules, even if there are no hops in this pig feed, there are no hops in this pig feed, and you can see it when you tear open the bag, this thing is simply yellow and yellow droplets, and it makes people disgusting to look at!"
