The whole family of villains criticized her wildly, but the princess treated her with medical treatm

"Your Highness, this is a sample produced by the Imperial City Tomato Sauce Factory."

Qingniao carried a jar of ketchup to Qiying's study.

Mu Tingxue had just finished writing a few words, put her pen aside, and glanced at the can of tomato sauce that was not yet available for public sale.

She makes a point of checking that the bottles are sterilized and sealed.

The method used to seal wine is to use a cork, which is sealed with wax around it. On top of the cork, a layer of cloth is wrapped around the mouth of the bottle, and a rope is wrapped around it.

"Has it been sterilized by high temperature?"

"My subordinates personally supervised that all the utensils for making ketchup were boiled in boiling water for one to two hours." As one of the eldest princess's confidants, Qingniao supervised the ketchup factory.

Yuanyang is in charge of the Imperial City Mill with Zhujiacun as its core, and handles everything related to soy products.

Qingniao originally managed the mustard shop, but since she got engaged to the most powerful thief in the world, Mr. Shen, the mustard shop in Yundu was left to Mr. Shen. Shen Daxia is a well-known person in the world. He has many friends from all walks of life and has a lot of skills. He also likes to rob the rich and give to the poor with a chivalrous spirit. Therefore, it is very difficult to leave a mustard shop that specializes in helping the poor and distributing cheap salt to the poor. Relieved.

With his hands free, Qingniao acted as the eldest princess's agent, coordinating business dealings with the Tang family.

This also means that Jade Bird needs to take care of all derivative products closely related to white sugar. The essential core raw materials for making ketchup are white sugar and white rock sugar, so the ketchup factory is also within her scope of responsibility.

"Your Highness, Princess, is there a better way to sterilize? Boiling at such high temperatures consumes too much charcoal."

Qingniao asked sincerely, "It's not that we can't afford charcoal. The raw material cost makes the sauce factory willing to give it up. The problem is that there is a shortage of charcoal this winter, and we can't buy such a large amount from the charcoal dealer at the moment."

It doesn’t just take a quarter of an hour to cook.

Every jar, porcelain, cork, spoon and shovel needs to be boiled for an hour or two. Even the big pot used for cooking tomato sauce needs to be disinfected every day. The workers in the ketchup factory were also given a piece of old soap each and strictly required personal hygiene.

"Charcoal resources are in short supply..."

Mu Tingxue pondered for a moment, "The best disinfection method is actually [-]% medical alcohol, not boiling water for an hour or two."

The boiling point of water is fixed.

It does not kill all bacteria.

But [-]% alcohol is different. It can be used for medical purposes and daily disinfection. The principle is that high concentrations of alcohol will quickly destroy the proteins on the surface of bacteria.

Even if the concentration is too high, the protein on the surface of the bacteria will quickly solidify into a protective film, and all substances, including alcohol, will not be able to penetrate further, and will not achieve a good sterilization effect. Therefore, after a series of research and tests by senior medical industry experts, the concentration was finally set at 75%.

"Alcohol?"

Qingniao was stunned for a while, frowned slightly, and said with doubt, "Did you buy the wine from the wine shop? There is a folk method of wiping wounds with white wine, but the effect doesn't seem to be very good."

It wasn't that she deliberately got into trouble with her master.

She had tried this method when she was growing up in the countryside when she was a child, but it really didn't work.

"Bring some Yunhuang liquor over here." Mu Tingxue decided to test it herself.

She can purchase [-]% medical alcohol in large quantities from modern pharmacies through medical representatives and then transport it here.

but.

Is that really necessary?

There was wine in ancient times, and after alcohol was distilled and purified, high-concentration alcohol could be produced at home. The required equipment is not complicated either, condenser tubes, three-mouth beakers, wide-mouth glass beakers, all of which can be customized with porcelain.

"Yes."

Qingniao went to the cellar of the princess's mansion to get it in person.

Since the master cannot drink alcohol because he will be poisoned, the amount of liquor stored in the house is small and is only used occasionally when entertaining guests.

Not long after, a jar of liquor appeared on the table in Mu Tingxue's study.

The wine jar is sealed with clay and has the words "Youzhou Fine Wine" written on it.

"Your Highness, this is the best liquor in Yunhuang, a tribute from the palace. It is also the most popular among the people." Qingniao explained.

"The place of origin is Youzhou?"

Mu Tingxue figured out the flavor, "Is it brewed by the Cui family?"

Sister Yan Yang's husband's family, the Cui family, has been the local emperor of Youzhou for generations.

Winemaking is a hugely profitable industry. Since Youzhou Fine Wine has such a great reputation, she doesn't believe it if the Cui family doesn't have a hand in it.

Qingniao smiled and replied: "Your Highness is very smart. This Youzhou wine has a history of more than [-] years. It was available in the previous dynasty. It is the proud work of the Cui family. Their wine restaurants are open all over the country. Thousands of them. Many drunkards have identified Youzhou’s brand.”

Due to the volatility of alcohol, Mu Tingxue put on a mask to prevent inhalation.

She personally opened the mud seal of Youzhou wine and tested the alcohol content.

The blue bird saw his master putting a long, slender stick that looked like crystal glass into the wine jar. He was surprised and asked, "Your Highness, what is this?"

"Alcoholometer."

A little longer than a thermometer.

After taking the test result, Mu Tingxue combined it with the alcohol content meter and performed the conversion, and came to the conclusion, "Only [-] degrees? The degree is too low."

Even the alcohol content of the red wine she brought from modern times was inferior.

Seeing the disappointed expression on his master's face, Qingniao hurriedly said: "This Youzhou wine is already the most intoxicating. Other liquors have a lighter taste than this one."

Mu Tingxue sighed: "The alcohol content is too low, and refining it will be very troublesome. It must be at least around [-] degrees."

Most ancient people drank heavily, and the alcohol content was generally not high.

High-concentration distilled liquor was developed in modern times. It is said that it was originally done to cater to the Soviet morons.

If Mu Tingxue wanted to purchase the finished wine directly in Yunhuang and purify the alcohol, the cost would be very high. The alcohol content is a bit too low. There is very little alcohol left in a jar of wine after purification.

Wanting to make homemade medical alcohol, I encountered resistance.

Mu Tingxue resealed the jar of Youzhou fine wine, sat on the pear wood chair, took out a pen and paper, and began to draw drawings of condenser tubes, three-necked flasks and other equipment needed to purify and distill alcohol.

After the drawing is drawn, the ink is allowed to dry.

Then he folded it carefully and put it into the cowhide bag: "Send it to Qinhou Mansion and give it to Mr. Qinhou or Sister Yun. Customize a batch of porcelain devices."

"Yes."

Qingniao didn't dare to neglect, and immediately took the cowhide bag to the Qin Mansion in person.

Mu Tingxue knew that it would take some time to build the equipment to condense and purify alcohol.
