"Sister Linzhi, can you do me a favor?" Ma Qiang smiled as he ate what he thought was the most innocent of all.

"Hmmm! What's busy? "Lin Zhi is very interested in being able to help.

"Organize your little friends to collect some flowers nearby, so that we can add floral fragrance to the soap, and your laundry will be fragrant in the future!" Ma Qiang picked up the white smoke and loess again and said, "You two go and talk to Sister Hu, let her help take care of it, and we will eat sweet and sour meat in the evening." ”

"Meow!"

"Meow!"

The two little tigers heard that there was something delicious, and one was more positive than the other.

The Child Labor Team Sets Out!

Ma Qiang instructed Guo Jin to carefully differentiate glycerin.

After an hour of saponification, the saponified wastewater has begun to divide into a clear and viscous liquid that floats on it and does not become solid.

Although glycerol is called oil, it is actually an alcohol, which is an extremely important chemical and can be used in food, medicine, daily chemical and other aspects.

For example, Ma Qiang is now using it as a wetting agent and sweetener in toothpaste.

"Now I'll configure the toothpaste, Lime will make the record, and Guo Jin and Liu Hui will assist." Ma Qiang began to make his first toothpaste.

"If we want to sell a product at a good price, then its quality must be guaranteed, and the quality must be guaranteed, and the formula must be consistent.

Now let's start the experiment, the first scheme of the experiment, five coins of friction agent, four coins of wetting agent, one penny of salt, one drop of honey, five drops of mint liquid, five drops of honeysuckle liquid..."

....

"Recorded, the taste is bitter, the viscosity is not enough, and there is more powder in the mouth after rinsing. Next is the second number of Fonagant, the friction agent is reduced to four coins, and the honey is increased by two drops..."

"Plan No. 17, increase to three drops of honey, four drops of mint sap, and two drops of honeysuckle sap."

....

Scientific experiments are such a process of continuous trial and error, as early as the birth of the universe when all the answers to physics, chemistry, mathematics, etc. have been determined, scientific experiments are in the continuous trial and error to gradually find the most correct answer.

The sun was setting in the west, and the small boxes contained the tried formulas, and Ma Qiang's mouth had long since lost the feeling of gargling, but he still had to try each formula himself.

Because only he knows what toothpaste tastes like in later generations.

"Are you still trying?" Guo Yin walked over with a yawn, sniffed his nose and asked, "What kind of smell is this, it smells good." ”

"Toothpaste, semi-finished product, now Plan Twenty-Three." Ma Qiang dipped a little in his toothbrush and began to rinse his mouth.

"How's it taste?"

"Yay!" Yue Yang gave a thumbs up, although he couldn't eat it in his stomach, the sweet and cool taste of toothpaste completely conquered him.

Isn't it the dream food of all foodies if you can eat it without eating fat?

"Really delicious?" Guo Yin was excited when he heard this, and he dug a little and licked it.

"It's so sweet, it's cold, and it tastes really good!"

"Although toothpaste is non-toxic, you can't eat a lot of it in your stomach, so be careful of stomach pain." Ma Qiang looked at the sun and decided to stop the experiment, although it did not taste as good as that in later generations, but it was already a revolutionary breakthrough for the current simple clear water.

"Let's choose the No. 13 plan first, I feel that the No. 13 is the best, and we will start mass manufacturing tomorrow, make a thousand boxes first, and make as many toothbrushes as you can." Ma Qiang clapped his hands and said.

"Did we succeed then?" Lu Qingling asked with some uncertainty, he had been experimenting all afternoon, and Ma Qiang could say a lot of shortcomings in each plan, as if none of them he could be satisfied with.

"Well, it's a success, everyone try it, you should be able to use it anyway." Ma Qiang stretched out his tongue and purred a few times, gargling his mouth all afternoon, and everyone had to feel numb in their mouths.

"This feeling is..."Guo Jin's eyes widened, although he had already heard Ma Qiang's experience report, but when he tried toothpaste for the first time, he was still amazed by such a cross-era product.

"It's sweet, it's cool, I feel like I'm going to float when I take a breath... Little Pony, is this toothpaste? Lu Qingcheng's eyes seemed to glow with golden light, and she felt that she could no longer accept that she only rinsed her mouth with water.

Sure enough, it's easy to enter luxury, but it's difficult to be thrifty.

"Purr.... Ha, bad breath has also decreased. "Yue Yang naturally has bad breath in his mouth due to greed, and he has low self-esteem because of this, but now he has found a good cure for this problem.

"Why are you so happy?" Lin Huan's voice sounded from behind, and Guo Ping and others followed behind him, thinking that the day's work was over.

"It's Lin Lizheng, fortunately, the toothbrush and toothpaste have been made, please try it." Ma Qiang asked Lu Qingcheng and others to teach everyone how to brush their teeth with toothpaste, and the people of Dasong Village felt the joy of brushing their teeth for the first time.

"Brother Pony, we've picked the flowers!" Lin Zhi took a group of friends to pick flowers for an afternoon, and it was really a full return.

"Daddy... What's wrong with everyone? Lin Zhi found that people were foaming at the mouth everywhere, and he was a little scared for a while.

"It's okay, here's your little brother's toothpaste."

"Yikes! I'm going to brush my teeth with toothpaste too! When Lin Zhi heard this, he also went to find a toothbrush and brushed his teeth.

"Lin Lizheng, Yueyang helped make a lot of honey today, and I don't need so much to make toothpaste, so why don't I cook a dish and eat it." Ma Qiang wanted to make sweet and sour pork, and every time he saw Sister Hu, he felt in debt. "Oh? Ma Lang is also good at cooking? Lin Huan found that this magical young man seemed to have nothing that he couldn't do.

"Well, when I was in our school, I would also cook by myself, which is the so-called do-it-yourself food and clothing." Ma Qiang thought of having sweet and sour meat to eat tonight, and he was a little excited.

"Do it yourself... It's really a famous saying. Lin Huan is knowledgeable, and when he heard it, he felt that there was a great truth in this statement, and he sighed in his heart that although this Ma Qiang's school was strange and had never heard of it, it could be seen from Ma Qiang's words that there were many capable people in this school.

"Then let me help you, and tell her if you need anything." Lin Huan called Wang's family, Ma Qiang thanked him first, and then said, "The ingredients for sweet and sour meat are simple, and now that I have honey, I still need some vinegar, I don't know if there is one in the village?" ”

Lin Huan nodded and said, "If there is wine in the village, there will naturally be vinegar, so let someone bring it to you." ”

Vinegar is also a traditional Chinese condiment, as early as the Spring and Autumn Period and the Warring States Period, there were workshops dedicated to making vinegar. By the time of the Han Dynasty, vinegar began to be widely produced, in fact, the method of making vinegar and wine was extremely imaginary, and even in legend, vinegar was invented by the son of Du Kang, the inventor of wine.

If the Spring and Autumn Period and the Warring States Period were a gastronomic desert, the current Eastern Han Dynasty can only be said to be a gastronomic wasteland, and the main ingredients used in Chinese cuisine in later generations have appeared at this time except for American crops such as chili peppers, and what is lacking is more cooking methods.

In later generations, there were 26 cooking methods such as stir-frying, exploding, boiling, frying, cooking, and frying, and even Ma Qiang, who loved to spice up his boring R&D life with food, did not dare to say that he had eaten them all, let alone made them all.

But home-cooked dishes like sweet and sour pork are Ma Qiang's good tricks.
