Li Erniu raised his head, took a big sip of the drink, and obediently held it in his mouth without swallowing it.

As soon as the drink was eaten, a foul smell instantly spread from the taste cells in Li Erniu's mouth to the cerebral cortex, and Li Erniu almost vomited!

Li Erniu was very upset! Wow! Qin Yu was really fooling him!

Just when Li Erniu was about to have a seizure, a burst of strange fragrance suddenly came out of his mouth! Li Erniu was about to float! The taste cells in his mouth were about to explode!

Goodong, Goodong, Li Erniu swallowed the drink in his mouth and took a big sip again!

This time too, it starts to stink, but in less than a second, it becomes very sweet!

"You stupid cow, leave me two mouthfuls!" Seeing that Li Erniu drank several sips in a row, Hu Baoguo hurriedly snatched the beaker in Li Erniu's hand!

Hu Baoguo knew that it was impossible for Li Erniu to lie to him, since Li Erniu drank it so sweetly, it means that this drink is really delicious!

Hu Baoguo took a sip carefully, and the stench in his mouth made Hu Baoguo almost vomit the drink in his mouth, but soon, the stench in his mouth disappeared, and it became very sweet!

Hu Baoguo's eyes moistened all of a sudden! This is the smell! This is the smell! I remember what my father told me at the time, this is the smell!

With a bang, Hu Baoguo swallowed the drink!

Hu Baoguo cried bitterly: "Father! What you said is not wrong! The secret recipe of our family is indeed the secret recipe of the ancients! It can really brew a very delicious health drink! I should not doubt you, and I should not blame you!"

After crying for a while, Hu Baoguo looked up at Qin Yu and bowed deeply to Qin Yu, "Xiao Qin, thank you! Thank you for making our family's ancestral secret recipe see the light of day!"

"Uncle Hu, don't get excited, although this secret recipe is fine, but there is still a little flaw! We know that it will become sweet in the mouth, so we dare to drink it, but ordinary consumers don't know that after smelling such a foul smell, consumers will definitely not drink it." So, we have to find out why the drink is smelly and sweet. ”

Qin Yu analyzed it very calmly.

"Yes, yes, yes, it's too early for me to be happy!" Qin Yu's words were like a basin of cold water, which extinguished Hu Baoguo's excitement at once, yes, it smelled so stinky, who would dare to drink it?

"It would be a pity if the ancient recipe was buried just because of such a small flaw!" Li Erniu looked sorry, he missed the taste just now.

Qin Yu studied the medicinal properties and pharmacology in the formula again, but after studying for a while, Qin Yu did not find a chemical reaction that would produce a foul smell!

The recipe looks perfectly fine, but what's the problem?

Seeing that Qin Yu was studying the formula, Hu Baoguo smiled bitterly and shook his head: "Xiao Qin, don't study it, I have studied this formula for more than ten years, and I know very well that they shouldn't have a chemical reaction! ”

Qin Yu's eyes lit up, he grabbed the parchment scroll on the table, and looked at it with blazing eyes! Even if it was an ancient seal character, Qin Yu could understand it!

Qin Yu looked through it carefully, and soon, Qin Yu became excited, I see! I see! Qin Yu said in a deep voice, "Uncle Hu, I know the reason!"

"What is the reason?" Hu Baoguo's spirit was shocked!

"The water quality is different! In ancient times, the water was not polluted! In modern times, due to various industrial pollution and the influence of smog, the water quality has become very poor! It must be that some substance in the water quality has a chemical reaction with the medicinal juice!"

"If there is a chemical reaction between the substances in the water quality and the substances in the medicinal juice, why does it become sweet in our mouths?" Gu Baoguo hesitated.

"Uncle Hu, it seems that you are not very good at chemistry, and your saliva contains a variety of biological active enzymes, which should be the role of a certain biological active enzyme to dissolve the smelly substance. ”

"It seems to make a lot of sense! If that's the case, as long as we use distilled water to make drinks, we can avoid producing smelly substances!" Li Erniu's eyes are glowing, if the beverage factory comes back to life, he doesn't have to worry about losing his job!

"No!" Hu Baoguo shook his head decisively.

Ha? Qin Yu and Li Erniu looked at each other, not knowing why Hu Baoguo shook his head.

"Why not?"

"You can't use distilled water to make drinks, drinks must be rich in certain minerals and trace elements, if you use distilled water for a long time, the body's immune system will collapse! ”

Li Erniu lowered his head in disappointment, it seemed that he was overjoyed!

"It turns out that there is this kind of chatter, it seems that it is really three hundred and sixty lines, and the line is the champion. Qin Yu sighed, and then looked at Li Erniu with a smile, "Brother Erniu don't be discouraged, you can't use distilled water, you can also use other methods! ”

"Add some ingredients?" Li Erniu looked at Qin Yu innocently.

"That's right!" Qin Yu nodded.

"What's the top?"

Qin Yu did not answer Li Erniu's words, but looked at Hu Baoguo with a smile.

Hu Baoguo's eyes lit up, and he suddenly burst out laughing: "Xiao Qin! You are really my nobleman! No, you are not only my nobleman, but also the nobleman of the entire beverage factory!"

Li Erniu was even more confused, he didn't know what Hu Baoguo said, Li Erniu scratched his ears and cheeks anxiously: "Uncle Hu, what are you talking about? ”

"You pig brain! No, you bull brain. Hu Baoguo raised his hand angrily and nodded Li Erniu's head, "Think about it, why doesn't the drink stink when it comes to our mouths?"

"Didn't Xiao Qin say it just now? It's because of saliva. ”

"yes, you still don't know what to put in your drink?"

Li Erniu was a little stunned, and his mind began to fantasize that the employees of the entire beverage factory kept spitting in the finished drink!

"Vomit...... Isn't this too disgusting?" Li Erniu almost threw up.

"What's disgusting?" Qin Yu and Hu Baoguo were stunned.

"According to the meaning of the two of you, you want to spit in the drink, it's disgusting to think about it, if consumers know about this stubble, our beverage factory will really be finished!"

Qin Yu and Hu Baoguo rolled their eyes at the same time, I really don't know what is growing in the mind of this fool?

"Who told you that you have to spit in the drink? As long as we analyze which bioactive enzyme in the saliva works, why not add this bioactive enzyme to the drink?"
