Compared to imported wheat flour, the price was higher.

“Haemi also makes bread these days and is interested in wheat.”

“I will take good care of it.”

“Aren’t you just asking out of curiosity?”

Seol Min-joo looked at me and asked.

“Yeah, not just out of curiosity.”

Her eyes widened at my words.

“Then do you have any plans to grow wheat?”

“Yes, depending on the circumstances.”

“Can I give you my personal opinion?”

“How much is it?”

“I think it would be good in many ways to grow wheat. It goes well with dairy products from the ranch. You can make bread using butter and milk, and you can even make cookies and yakgwa.”

“By the way, yakgwa also contains flour.”

“That’s right, it goes into a lot of secrets.”

Seol Min-ju even used exaggerated hand gestures. I could feel the desire to grow wheat.

It was the way out of the ranch.

Bang Hyun-sik received a call.

His voice trembled as usual.

“Hyung, I think I made sesame oil without benzopyrene.”

After the experiment was over, he decided to visit the lab with me.

I wondered if he had visited the lab alone.

“Did you go to the lab?”

“No, we decided to go to the institute with my brother. It is yet to be confirmed.”

“But how do you know?”

“You will know when you come too.”

He said you should come and see for yourself. I was also curious as to why you were so sure.

“I will go home.”

“Yes, I will be waiting.”

While I was looking for a machine, he was experimenting with sesame oil.

It was an experiment to make sesame oil under various conditions.

I had to find the temperature and roasting time to heat the sesame seeds.

After the experiment was over, the plan was to take the results to the lab.

Among them, it was a problem to be solved by finding sesame oil in which benzopyrene was not detected.

Bang Hyunsik was out in front of the house.

I got out of the car and walked over to him.

His face looked different from a few days ago. His face was pale and one of his eyes was red and bloodshot.

“Did you sleep well?”

“I made sesame oil to save time for sleeping.”

Contrary to the state of his face, his expression was too bright.

“The sesame oil I made is in the room.”

I followed him into the room.

Bottles of sesame oil were placed neatly next to an old milking machine. The room was full of sesame oil bottles.

There was a small amount of sesame oil in the bottle. Each bottle had a label attached to it.

The temperature and time at which the sesame was roasted were written down in detail.

“How many did you make?”

“I only made 100 of them. You didn’t make more than you thought, did you?”

The principle of the milking machine Bang Hyun-sik had was the same as those sold in the market.

It was a machine that squeezed oil by hot pressing. In order to squeeze the oil from roasted sesame seeds at a low temperature, it had to go through a difficult process.

It had to be repeated several times to barely get the oil.

This was the reason for making a separate oil press.

Hyunsik Bang would have stayed up all night preparing sesame oil.

“It was hard.”

“no.”

I looked around the bottle of sesame oil.

“What kind of sesame oil are you talking about?

Bang Hyun-sik picked up the sesame oil bottle in the middle.

Yellow oil in a transparent bottle.

“How did you know it was benzopyrene free?”

“I once called Dr. Seo Woo-young while making sesame oil. I am so curious.”

“What did you ask?”

“As I kept making it, there was something I could see.”

“What did you see?”

“It’s sediment.”

“precipitate?”

“Yes, it is the sediment that forms when making sesame oil. The more sesame seeds are roasted, the more sediment will come out. Because it is roasted at a low temperature, there is less sediment.”

“therefore?”

“I thought it might have something to do with the sediment and benzopyrene. So I asked Dr. Seo Woo-young about that.”

I looked at the sesame oil bottle again.

No sediment was seen.

It was almost transparent yellow.

“I was told that sesame oil without sediment may not produce benzopyrene. Almost right.”

Bang Hyun-sik said with a smile.

I opened the lid of the sesame oil bottle.

It smelled different from regular sesame oil.

The sweet and savory scent was enough to tickle the tip of his nose.

“It smells good.”

“Yes, I am suing you softly.”

“Shall we go to the lab and check it out?”

“like.”

We loaded all the sesame oil bottles in the room into the car.

I was curious what the results would be.

self-actualizing power

We arrived at the Jirisan Farmers’ Research Institute.

A bottle of sesame oil was placed in a box and moved into the laboratory.

“How many more bottles of sesame oil do you have?”

Seo Woo-young looked at the oil bottles and asked. It was a face that was surprised by the huge amount.

“The quantity is quite good.”

Hyeon-sik Bang used sesame seeds sparingly. A minimum amount of sesame oil was squeezed out in each experiment.

Each bottle contained about 30ml of sesame oil. 100 bottles of sesame oil were placed on the lab table.

Seo Woo-young took out one of the sesame oil bottles from the box.

It was the disease that Hyunsik Bang showed me that the experiment was successful.

“It has no sediment.”

Seo Woo-young waved a bottle of sesame oil and said.

In case u have any questions u can refer to uwumtl dot com for references

No matter how much shaking, no sediment was seen.

He looked at Bang Hyun-sik and smiled.

“It seems that sesame oil was made under various conditions. We will check them all.”

“Will the test take a long time?”

“Let’s do it as soon as possible.”

Seo Woo-young and Lee Young-ho entered the laboratory with a bottle of sesame oil.

Hyunsik Bang and I waited for the results to come out.

“I’m a little nervous.”

Bang Hyunsik said with a nervous face.

“I was so confident, but when I came to the lab, I was nervous.”

“I was only told that the sediment could be used to determine the presence of benzopyrene.”

“What would you do if you heard benzopyrene?”

“You have to start all over again.”

I could feel the power in Bang Hyunsik’s voice.

“It’s my expectation, but I don’t think that will happen.”

“Then even better.”

He said with a smile on his face.

“Are there any cracks left at home?”

“I almost used up all the sesame seeds I grew this year.”

The sesame was used up because of the experiment.

“I’m going to buy sesame seeds soon.”

“To whom?”

I told him about Yecheon Cheonjin Lake. His expression brightened when he said that he was a person who had been trained in dried persimmons like Bang Hyun-sik.

“When I buy sesame seeds, I will go with them.”

Then, the door to the lab opened and Seo Woo-young and Lee Young-ho came out. In one hand he was holding a bottle of sesame oil and a document.

“Does the written on the bottle indicate the temperature and time of roasting the sesame seeds?”

Seo Woo-young asked Bang Hyun-sik.

“Yes, temperature and time.”

“Benzopyrene was not detected in sesame roasted at 48 degrees for 30 seconds.”

Bang Hyunsik raised his arms and shouted hurray. He looked happy like a child.

“What about the others?”

I asked Seo Woo-young.

“First of all, almost no benzopyrene was detected in sesame roasted below 48 degrees. However, if the roasting time exceeds 30 seconds, a trace amount of benzopyrene was found.”

When Seo Woo-young finished speaking, Lee Young-ho opened his mouth as if flipping a baton.

“At 48 degrees or higher, benzopyrene was detected regardless of the roasting time of sesame. It seems that the temperature below 48 degrees is the temperature at which benzopyrene does not come out.”

Fry at 48 degrees for 30 seconds. That was the condition that benzopyrene did not come out.

It was a number that had to be put into the default value for the oil press.

“Bang Hyun-sik would do well as a researcher. I had no idea it would create so much data.”

Seo Woo-young looked at Bang Hyun-sik and said.

“Thank you for your hard work.”

Hyunsik Bang nodded to the two researchers.

“Thank you, this is what we do. Hyunsik Bang really did all the hard work.”

We loaded the sesame oil bottle back into the car.

Bang Hyun-sik said as he got into the car.

“I’m glad the results are good.”

“I told you, it would be good.”

“It was exactly what he expected. But I have one concern.”

“Tell me you’re worried.”

“Honestly, it was very difficult to squeeze the oil below 48 degrees. It takes ten times more force than normal to squeeze a bottle of oil.”

“No need to worry about that. I will borrow the power of a machine.”

I told him about the principle of the machine.

From the spiral screw to the heated wire, it was a moon thing. The roasting time could be shortened.

With that machine, he could make a lot of sesame oil by himself.

“With such a machine, I think it would be possible to easily make sesame oil even at low temperatures. And there is one thing I want to tell you.”

“What?”

“When I buy sesame seeds, I want to go with them. You can’t go alone.”

Bang Hyunsik looked into my eyes and said. It was a promise that had to be kept unconditionally.

“Yeah, I’ll go with you.”

* * *

He took Bang Hyun-sik home and headed to the office.

There was something to discuss about the planting of the planned crop.

I called Han Ki-tak and Baek Min-seok.

“What’s wrong with you calling me today?”

Baek Min-seok asked as if he was surprised.

“By the way, I’m a little busy right now. It’s because the client has everything from server to server.”

“I know you are busy. I need you today.”

“Should I be there?”

Baek Min-seok opened his eyes and asked.

“Isn’t it a little more leisurely after New Year’s Day?”

“When that time comes, it will be a little more relaxed.”

“Then let’s go somewhere with me.”

Baek Min-seok’s gaze turned to Han Ki-tak. He looked like he knew something.

Han Gi-tak raised his hands and made a gesture of ignorance. Han Ki-tak was also watching me.

“Where are you planning to go?”

“USA.”

“USA? where in the usa? Why?”

“California.”

I talked about the California Agricultural Fair. It was an agricultural fair held at the beginning of each year.

It was the largest agricultural fair in the world.

“If it were an international agricultural fair, it would be worth it.”

Han Gi-tak said as if he understood.

“Then why are you going with me?”

Baek Min-seok asked.

Han Ki-tak looked at me as if he had the same question.

“Minseok, there is something you need to look at.”

“At an agricultural fair?”

The fair was not just a place to share farming techniques and introduce agricultural machinery.

In the early 2000s, cutting-edge agriculture began to be introduced at the fair.

Agriculture and advanced technology were merging.

“You need a programmer’s eye.”

“A programmer’s perspective?”

Baek Min-seok still had a look on his face that he didn’t know.

Han Gi-tak’s face was different.

“Coming to think of it, Deokmyung is right.”

“What?

Baek Min-seok looked at Han Ki-tak and asked.

“Remember I went to Germany?”

“I remember. I went to Germany to see a robotic milking machine.”

A robot milking machine came out of Baek Min-seok’s mouth. He then nodded.

“I understand, but it was a machine. Would a programmer like me help?”

“Even machines are driven by programs.”

Han Ki-tak looked at Baek Min-seok and said.

“That’s right. Machines also return to programs.”

Baek Min-seok seemed to have organized his thoughts.

He was a natural programmer. A key member of the Jirisan farmers’ shopping mall.

The purpose of the fair was not just to visit. The cutting-edge technology seen at the fair had to be made by the farmers of Jirisan.
