Soybeans are everywhere these days, but no one associates them with oil.

It’s not that the ancients were stupid.

But today’s oils are almost all meat oils.

The concept of vegetable oil has not been deeply rooted in people's hearts. In addition, the preparation of food is nothing more than boiling, steaming and baking, so it is not easy to find vegetable oil.

In fact, even after the discovery of vegetable oil, the ancients used sesame oil for a long time, and soybean oil was not discovered until later.

However, Zhang Qian has not yet sent his second mission to the Western Regions, and sesame seeds have not yet been introduced to the Han Dynasty.

So soybean oil was a common thing for Tang Qi, but for the people of the Han Dynasty, it was like another three-dimensional earthquake!

Princess Pingyang stared at the servants pounding beans with bright eyes, and she held the palm of Mr. Wei's little hand and tightened it unnaturally.

Mr. and Mrs. Wei were pinched in pain, but they were very sensible and did not make a sound.

From his mother's expression, he knew sensitively that he seemed to be witnessing something big.

The Hou Mansion had enough manpower, and in a short time all the fried beans were pounded into fine particles.

The next tools are not readily available.

Fortunately, the mansion is big enough, and there is also a large group of rockeries.

Tang Qi was not interested in admiring the garden, so he simply asked someone to go to the rockery group and knock a large and heavy boulder.

Thanks to the pulley block, the servants can move it very quickly.

This small tool had already been known to Liu Che and passed on to craftsmen all over the world, so it did not attract Princess Pingyang's attention.

All her attention was on the inconspicuous pile of soy flour.

Wrap the broken beans in cloth and place them on a flat stone.

According to Tang Qi's instructions, special notches for oil leakage were made on the stone.

Then press another boulder onto the cloth bag.

Grind slowly.

At this time, the servants basically knew what Tang Qi was going to do. The strong man in charge of grinding the beans even held his breath.

Can soybeans really produce oil?

Under the expectant and nervous gaze of everyone, time passed quickly.

It is not difficult to get oil out of beans.

"Tick tock!"

A drop of golden liquid slowly dripped down the slot into the large bowl that had been prepared.

"It's oil!"

"It's oily!"

The servants were so excited that they almost jumped up, and cheers filled the sky.

The steward, who was over 150 years old, shakily walked to the bowl, dipped his fingertips in some soybean oil, and carefully put it into his mouth.

“It’s really oil!”

The steward was so excited that he burst into tears.

"By God, this is oil!"

Regardless of the steward's uneducated appearance, Princess Taiping's performance was not much better.

Regardless of her appearance, she squatted down and stared carefully at the slot where oil was dripping. She breathed very softly.

It seems that he is worried about disturbing something so that the beans will no longer produce oil.

Princess Taiping also had tears in her eyes.

It is difficult for people who do not live in ancient times to understand the excitement of everyone at this time.

Oil!

Salt!

These two items are serious problems that restricted the living standards of ancient people!

Especially in the Han and Wu dynasties where productivity was not yet developed, no matter how powerful the military or brilliant the culture was, they could not hide the fact that even good men were reluctant to let go of oil and salt.

The poorer people could live for a year with just a piece of salt stone or a piece of pig skin at home.

Even the stewards of Tang Qi's house still rolled pig skins to eat oil at home, which was a little better than the common people, but it was just enough to meet their health needs.

That's the steward of the Hou Mansion!

This shows how serious the people's shortage of oil has become.

But now, Tang Qi tells them with facts that soybeans that even the poor can afford are actually treasures that can produce oil!

How can you not be excited!

Among everyone present, the only two people who could remain calm were Mr. and Mrs. Wei, besides Tang Qi.

Tang Qi was not surprised.

Mr. and Mrs. Wei are still young. Although they understand what the adults are excited about, they cannot empathize with them.

He raised his little face and asked crisply: "Da Nong Ling, beans can really produce oil!"

"That's right, not only soybeans, but other beans can also be used." Tang Qi pinched Mr. Wei's little face that still had some baby fat, "but soybeans produce the most oil and are the most cost-effective."

"Tranquility!"

Princess Pingyang suddenly shouted loudly, and Tang Qi was startled by her sharp voice.

I thought pinching a child's face was a serious matter in the Han Dynasty, which made the child's mother angry.

But when she looked up, Princess Pingyang's eyes were still glued to the soybean oil.

"I'd like to ask An Dinghou. You said soybeans produce the most oil. I wonder how much oil they can produce?"

In the Han Dynasty, there was no such thing as a saying that a woman's lack of talent is a virtue. As Liu Che's sister, Princess Pingyang also had the world in mind.

Tang Qiyun replied calmly: "With today's productivity level, it is still not possible to maximize the oil extraction value of soybeans."

"The oil yield is about 20%, that is, ten pounds of soybeans can squeeze out about two pounds of oil. But there is no need to worry about waste. The soybean meal left after oil extraction can be made into bean cakes, which is good as meals or fed to poultry.

"

"Although the rest of the beans can also produce oil, it is estimated that the oil production rate will not reach 20%."

After sweet potatoes and potatoes spread all over the country, people will probably not have to save so much to use soybean meal as rations. At that time, they can be taught how to breed on a large scale to avoid wasting soybean meal.

Every time Tang Qi explained something, Princess Pingyang's breathing became faster.

Two percent!

Ten pounds of soybeans can squeeze out two pounds of oil!

"Father, you continue to stare at the oil here." Princess Pingyang suddenly stood up, holding a large bowl with half a bowl of oil in one hand, grabbing Tang Qi's hand with the other and walking out, "After settling down, follow me.

I will go into the palace to see His Majesty!"

"Hey, eh, wait!"

"Can't wait!"

Tang Qi was embarrassed to compete with the woman, so he could only be dragged away passively, with a look of helplessness on his face.

Do you need to be in such a hurry?

Isn't it just to get some soybean oil? I haven't had time to tell my next plan!

From Princess Pingyang's point of view, of course it is necessary to be so urgent.

The faster it goes, the faster people all over the world can eat cheap and good oil!

Fortunately, Princess Pingyang is not short of money and knows the righteousness well.

If it were another more domineering royal relative, what he would be thinking about at this time would be how to silence Tang Qi and make a lot of money, rather than benefiting the common people!

Liu Che had just finished lunch at this time and was about to ask if there were any military reports from the front line to counter the rebellion, when he heard Princess Pingyang and Tang Qi urgently asking for a meeting.

Princess Pingyang aside, every time Tang Qi appears, he always brings good things!

Liu Che quickly asked people to come in, and then retreated to the left and right.

Before he could ask, Princess Pingyang said directly: "Your Majesty, there is a way to make oil from soybeans in Anping, and the people of the world will be blessed!"

It took Liu Che a moment to react, and he stood up suddenly without even noticing that the pen and ink had been overturned.
Chapter completed!
