The Notre Dame system is arrogant again

Chapter 495 Knowledge is Power
As Zhang Xiaohua said, she took a box and opened it. Inside was some pre-made wax with patterns of animals, plants and cartoons engraved on it.

"This is what I made last time, you can try it."

Duan Li took out a cotton thread and lit it with a torch, because it was daytime and it wasn't very bright, but there was definitely less smoke.

"It's really good." Duan Li praised again and again, pointing to the pattern on the candle, and asked, "Is this made of a mold?"

"Yes, you can do it in different ways, such as adding red paint to make happy birthday, or make a Chinese zodiac sign and give it to others as a gift. In short, don't use them as candles, but use your rich imagination."

Duan Li looked at her.

"Then get a few beautiful boxes with silk in them, put them in, and the value will double at once, right?"

Zhang Xiaohua snapped her fingers at him.

"clever!"

Duan Li moved the corner of his lower lip, then blew out the candle, turned his head and pointed at the remaining impurities in the pot.

"There, is that the precious thing you mentioned?"

The piece of paper I saw before briefly introduced three things: soap, candles, and glycerin. He can still imagine what the former two are and how much economic benefits they can bring, but the latter is glycerin. What are you doing.

"Yes, this is the most valuable thing."

Standing by the side of the pot, Zhang Xiaohua sighed as she looked at the contents inside. Knowledge is power. This sentence is applicable everywhere!

Glycerin is a colorless, sweet, clear and viscous liquid. It is an extremely important chemical raw material with a wide range of uses, covering almost most chemical fields.

Food processing, pharmaceuticals, cosmetics manufacturing, industrial machinery lubrication, organic synthesis, plasticization and other fields have applications.

Even, at the beginning of the twentieth century, glycerin was the main raw material for making explosives!

After simple dilution and clarification, glycerin sweet water can be extracted from the waste liquid. This half pot of waste liquid contains about [-]% pure glycerin.

Glycerin sweet water with alkaline sediment removed is light yellow and has an unpleasant stench.

Zhang Xiaohua slowly poured the stinky water into the jar, and after a while, water flowed out of the thin tube at the bottom of the jar. Surprisingly, what flowed out was not yellow water, but a clear and transparent liquid.

Then do a simple distillation to extract pure glycerin.

Zhang Xiaohua turned her head to Duan Li and said.

"That's what we get rich on."

Although the application of glycerin is very wide, the most practical, profitable and safest way is to use glycerin as a food additive.

To be precise, it is a fruit wine additive.

In ancient times, productivity was not high, and there were many natural and man-made disasters. Food was very important, so the control of wine was very strict. Except for the government-registered Zhengdian restaurants in Dazhou, private people were not allowed to make wine. Other shops can only go to government-run wine shops if they want to buy wine So go to buy wine koji, and then sell it.

But this does not include fruit wine, and does not limit folk wine brewing with fruit.

One is that there is no need to worry about harming people's livelihood when brewing fruit wine. The other is that the brewing level of fruit wine here is extremely poor, muddy, bitter and astringent.

The ancients did not know that all fruits contain a substance called tannin.

Tannin is the source of all the bitterness and astringency in the fruit. No matter what kind of fruit is fermented, the tannin cannot be decomposed and remains in the wine. The naturally brewed fruit wine tastes bitter and astringent, which is extremely unpalatable.

Glycerin can just decompose the tannins in the fruit wine and remove the bitter taste in the wine.

In addition, the warm and sweet taste of glycerin can greatly improve the quality and taste of fruit wine, and it is an excellent fruit sprinkle additive.

As long as the bitterness of the fruit wine is removed, and then the wine is filtered and clarified to reduce the alcohol content, the sweet and clear fruit wine with low lightness will become the favorite drink of women and children!
The boiling point of glycerin is higher than that of water, as long as the sweet water containing glycerin is heated to [-] degrees, and the water is evaporated, pure glycerin can be obtained.

The purity of the glycerin extracted by this local method is naturally not up to the modern level, but it is enough to be used as a fruit wine additive.

This is her big business, and this big business needs all kinds of conditions, and she has to deal with the government. She can't do it as a nine-year-old child, so she can only hand it over to Duan Li.

After extracting the glycerin, add it to the fruit wine you bought, and ask Duan Li to taste it.

Duan Li saw that the wine everywhere was clear and bright, exuding a faint fruit flavor, he picked it up and took a sip, his eyes lit up, it was sweet and sour!

Zhang Xiaohua smiled when she saw his expression.

"You can filter the fruit wine directly, or you can add egg white to the fruit wine, stir it well, let it stand for a while, the impurities in the wine and the egg white will precipitate, and you can get a clear wine. It's just these two methods It can’t improve the taste of the fruit wine, so glycerin is used. I think you can also try adding saccharin, or a little salt, and give it a nice name, such as ice and fire, sweet and sour, it’s me, and then pack it well, Make a series! By the way, I have spent a few bottles, take a look!"

Zhang Xiaohua went in again to rummage through, and took out some papers for Duan Li.

"Look, that's all."

Duan Li took it over and took a look. The bottles on them were all kinds of strange, bright colors and beautiful patterns. The same thing was that the sizes marked were very small, only the size of the palm of your hand.

He looked carefully, and found that those patterns were all from the stories that Zhang Xiaohua had drawn, so he couldn't help but look at Zhang Xiaohua.

Zhang Xiaohua smiled like a fox who stole a chicken.

"See? These wine bottles are very small, and the alcohol inside is very low. They are for children and women, and they are made more delicate. I think in the near future, they will become a symbol of the banquet in your aristocratic circle! "

Although Duan Li was not in a good mood, he was also amused by Zhang Xiaohua's aggressive symbol.

But he has to admit that what Zhang Xiaohua said is right, if it works properly, it will definitely become a must-have drink for the gatherings of those backyard women.

"You're right, this is a big industry. We not only need to make fruit wine, but also burn your special wine bottle, customize the box, and find a store..."

Duan Li said while thinking, slowly speaking out the sales plan.

"...Put out our name."

"Brand!" Zhang Xiaohua said, "From now on, everything we produce will be branded with this brand."

"Brand? Interesting." Duan Li paused, "Just call him Xiaohua!"

"Huh?" Zhang Xiaohua was taken aback, "Isn't it too casual to use my name?"

"You came up with your name, it's the most suitable name. Also, Xiaohua, it's catchy, easy to remember and easy to write. Besides, there are many people named Xiaohua, and no one will suspect you."

"Xiaohua Soap, one of the Xiaohua Fruit Wine series, the two heavens of ice and fire! The second of the Xiaohua Fruit Wine series, sour and sweet is me?!"

"It's not bad, isn't it?"
