Autumn leaves and frosted garlic are not very good, pounding garlic mash is a good hand, not long after, the half bowl of peeled garlic cleaned and mashed garlic.

Qi Lele looked at the almost mushy garlic paste, and praised with a smile: "It's really amazing to pound it so delicately."

The two of them whispered, "Young Lady Xie compliments."

"Find a clean crockpot, put the mashed garlic in it, soak it in water, seal it, and wait for ten hours before you can extract the allicin," he said.

"Do you use the spring water you just received or the pure water?"

"Pure water? What's that?"

Akiba said: "It is extracted from the mountain spring water by my mother-in-law, and it is used to make lipstick on weekdays, it is colorless and tasteless, and it seems to be purer than the mountain spring water, so it is called pure water."

Isn't that distilled water?

Qi Lele said, "Then let's use pure water."

The two answered, and went their separate ways, one continuing to mash the garlic, while the other was busy washing and soaking.

Qi Lele peeled half of it, and suddenly remembered something, the allicin seems to only be stored for three or five hours at room temperature, and its activity will disappear, so it has to be used as you go!

"That's all for now."

Granny Du has extracted a wave of alcohol.

"The old man doesn't know if this is the alcohol that the young lady wants, so I ask the young lady for some advice."

Qi Lele took it and smelled it, but he didn't smell any big difference between the smell of wine and the previous soju, and he thought that the concentration should be far from enough.

After thinking about it, she took a small saucer, poured some distilled liquor into it, and then took the fire fold to light it.

Sure enough, it didn't ignite.

Granny Du couldn't help asking, "But is it wrong?"

Qi Lele shook his head: "Mistakes should be good, mother-in-law, don't worry."

As she spoke, she poured another small cup and handed it to Xie Zi'an: "Let's try it, whether this purified wine is more fragrant than that soju."

Granny Du's face changed slightly, and Song Mingshan jumped in with an arrow.

"Why don't you let me try it, I'm not afraid of the young lady's jokes, I've always been a good wine." new

As soon as the words fell, Xie Zi'an had already taken the wine cup and took a sip.

"How?"

Xie Zi'an was silent, took another sip, and then said, "It's really much richer than ordinary soju, what did Madam do?"

Qi Lele said, "I didn't do anything special, I just used that distillation dish to purify it."

After speaking, she looked at Granny Du: "Mother-in-law, what you did is right, but the purity of this alcohol is not enough, and it needs to be extracted many times before it can be done."

Granny Du pondered, "Do you have to extract it to be able to ignite?"

Qi Lele nodded: "At least seventy percent purity can be ignited."

"The young lady wants more than seventy percent purity, right?"

Qi Lele thought for a while, and said truthfully: "Seventy percent is indeed not enough, but it is not too much, what I want is a concentration of nearly eighty percent."

"What the young lady just said is that if there are no water stains after burning, it must be nearly eighty percent of the concentration?"

Qi Lele shook his head: "That should be at least ninety percent or more."

Granny Du was thoughtful.

Qi Lele was afraid that she would drill the tip of the horns, so he hurriedly said, "I also just remembered that if it is used for disinfection, it only needs nearly eighty percent of the purity."

"To achieve more than 90% purity, it is difficult to achieve it with distillation dishes alone, and it needs to be supplemented by other means, but I can't remember how to do it for a while."

Granny Du showed a gentle and kind smile and said, "The young lady's intentions, the old body understands, and the old body will try his best to extract nearly eighty percent of the alcohol for the young lady."

"There's Granny Lao."

"The young lady is polite!"

After a while, it was not too early, Qi Lele said: "This alcohol is not urgently needed, mother-in-law, you can come slowly, as for allicin, I will tell you again tomorrow."

Granny Du responded one by one.

"That's right! When extracting alcohol, we must pay attention to fire prevention, and we must not touch open flames."

"The old man remembered."

When the carriage was far away, Granny Du turned around: "You go and prepare some simple food, and from now on, we will take turns to rest."

Qiu Ye and Hanshuang knew that Granny Du was planning to stay up all night to extract alcohol, and they were not surprised, so they only said, "Mother-in-law, you lie down for a while."

Granny Du said, "Don't worry, I'll take you to extract it first."

"Yes."

In the carriage, Xie Zi'an asked, "What is the maximum purity of alcohol?"

Qi Lele didn't hide it from him: "If you have the right utensils, you can get almost 10% pure alcohol."

Xie Zi'an looked accustomed to it, as if he had expected it, and only asked, "What kind of utensils do you need?" How?"

Qi Lele didn't answer and asked, "Do you remember the colorless and transparent glass I mentioned to you?"

"Glass?"

Qi Lele nodded: "Yes, it's glass, and you need to use glass to make a special shape of the distillation device to distill high-purity alcohol."

Xie Zi'an was silent.

Qi Lele said, "What I just said is not a lie, as long as the alcohol used for disinfection reaches seventy and a half purity, it is fine, and Xianggong does not have to be obsessed with the highest purity."

"The alcohol used for disinfection is only seventy and a half percent pure, but the lady just mentioned nearly eighty percent, why is this?"

What is it like to have a smart husband? It's probably that I won't stop if I don't ask you about everything!

Qi Lele took a deep breath and said, "In addition to alcohol, there are many other things in soju, and to purify alcohol from soju, there must be some other impurities. I was worried that it would affect the effect of alcohol disinfection, so I took it upon myself to add half of it."

"The real alcohol used for disinfection is made with nearly 10% pure alcohol mixed with pure water?"

Qi Lele blurted out, "You even know this?"

Xie Zi'an smiled lightly: "Madame's expression when she heard the pure water just now was too surprised, so I remembered it."

Qi Lele simply lost his temper: "Yes, yes, yes! You're smart, but it's a pity you didn't get it right this time."

"Oh?"

"Disinfectant alcohol, also known as medical alcohol, is not extracted from soju, but by a different method," said Qi Lele.

"As for the method, I can't think of it now!"

Xie Zi'an laughed softly again, and really didn't ask anymore.

Song Mingshan drove the carriage, looking at his nose and nose, but he didn't hear anything, and drove the carriage home steadily.

I saw that a carriage had been parked outside the door, and in the courtyard, someone was talking, and the tone didn't sound very good.

"It's nonsense! The eldest prince and young lady don't understand, don't you understand either? All the medical skills have been read into the dog's belly?"

"This evidence of cowpox, although it can heal itself, but how much is the self-healing? Huh?"

"Don't you know what happened to those who healed themselves? There are only a few words in the medical book, so you should be blind and not look at it, right?"

"With such a contagious disease, you actually let them live with the eldest prince and the young lady?"

"Nonsense! It's nonsense!"
