She remembered that Dr. Wang, who gave her name at that time, said that although Dr. Xu, the holy hand of orthopedics, was in the Wang Family Hospital, he was extremely free, and the Wang family did not instruct him.

Dr. Xu's temperament is a little weird, but he only likes food, especially he likes to travel around and taste novel food......

This is also one of the reasons why Jing Tian is in a hurry to develop new foods in the past two days.

She wants to use food that has not yet appeared in this era to get this Dr. Xu!

After Jing Tian inspected the alkali stone with great interest, he handed over the three small ones to Chen Lei and went back to the house to study them.

In his previous life, although Jing Tian was engaged in finance and economics, he also studied basic chemistry in middle school.

It is still possible to refine some edible alkali with raw materials such as alkali stone, miscanthus nitrate and lime.

Simply, she didn't have anything to make the most of it, and she needed to refine these substances into various chemicals.

She just wanted some edible alkali to make a non-sour bun.

However, to be honest, the various refining tools in this era are really very scarce and improvised.

When Chen Liang returned to the house, he saw that Jing Tian was sometimes heating up, and sometimes pouring things in various bowls and jars.

No matter how he looked, it looked like he was alchemy.

Seeing Jing Tian's concentration, he couldn't bear to disturb him, so he let her go.

As the old saying goes, salt is dried in summer and alkali is fished in winter.

Soda stone, that is, the associated trona block in the salt lake. However, these alkali blocks are not pure, and they contain many other impurities, which need to be separated and synthesized through a series of chemical reactions.

If simply treated, these alkali stones can only form a highly corrosive caustic soda.

It seems that caustic soda is used to make soap, but since the store in the capital called Yipin Leisurely has made a gelatinous fragrance that can be cleaned by her, for a while, her desire to study soap is not strong.

After several purifications and reactions, edible alkali is finally refined.

In fact, in the Ming Dynasty in the history of Huaguo, where Jing Tian lived in his previous life, it was already recorded that people made things for washing clothes and making pasta by refining the alkali stone in the salt lake. Moreover, the miracle doctor of the Ming Dynasty, Li Shizhen, also recorded alkali stone in the Compendium of Materia Medica.

Jing Tian went back and forth for a long time, and failed several times.

Originally, this aspect was not her specialty, and after making a few pungent failures.

Jing Tiancai finally refined edible alkali that can be used as a food additive.

Holding her finished product in one hand, she turned around excitedly, eager to share her joy with others.

"Huh? When did you come over? ”

As soon as I turned around, I saw the person I wanted to share the most.

Chen Liang smiled softly and said, "Since you started alchemy, you have come. Have you made it? ”

Chen Liang stepped forward to look at the bowl in Jing Tian's hand, and said suspiciously, "Why isn't your pill round?" Did it still fail? ”

Well? Jing Tian was stunned, and then rewarded Chen Liang with two white eyes. What is this?

But I don't blame him for misunderstanding, after all, in this era, it seems that only Taoists will burn these things around when they are alchemy.

"I'm not an alchemy!"

As she spoke, she held the bowl containing edible soda in front of Chen Liang.

"See? This is baking soda, as long as you add this to the noodles, the resulting bun will be fragrant and soft, and there is no sourness, it is super delicious! ”
