"Professor Oil" He Dongping: "Squeeze" each grain of rice and "refuel" for domestic edible oil

In the China Oil Museum in Wuhan Light Industry University, 4 black particles of sesame size are placed under the magnifying glass for people to visit.

This is the Han Dynasty carbonized rice that was unearthed in the Qujialing Cultural Site of Jingmen City, Hubei Province, and it was also the "Treasure of the Town Pavilion" of the only oil museum in the country.

Why is the "Treasure of the Town Pavilion" of the Oil Museum? What is the connection between rice and edible oil?

He Dongping, the chief designer of the China Oil and Dead Museum and a professor at the School of Food Science and Engineering of Wuhan Light Industry University, has a research result: refining edible oil from rice.

The scholar, known as the "Professor of Oil," has been engaged in oil research for more than 40 years, and has won the first prize in Hubei Province Science and Technology Progress. After more than 20 years, he studied key technologies for breaking through rice oil processing and "refueling" for domestic edible oil.

At least one -third of He Dongping's 65 -year -old He Dongping traveled to and from oil factories across the country. He said that the retirement time limit of countdown seemed to push him invisible hand, "For the sake of fat, there are many things to do."

"Squeeze" a grain of rice

A pot of oil, an umbrella, a lamp ... In the Chinese oil museum, such a huge relief shows the life of the ancients a thousand years ago.

"It almost summarizes the scene of oil use." He Dongping said that the oil produced by the squeezing process can be food, waterproof on the surface of oil paper umbrellas, or as fuel for lighting.

China is one of the earliest countries with the earliest consumption of oil crops in the world's oil crops. However, it was not until the 1950s that my country began to increase the production of oil production represented by the promotion of rice bran and corn germ oil.

Because of the galcin and glycol, rice oil with higher quality and nutritional value is listed as one of the three major nutritional healthy oils by the United Nations Food and Agriculture Organization.

"During the processing of rice, a large amount of rice bran will be produced. The rice oil made from rice bran is also called rice bran oil." He Dongping said that in my country, most of the rice bran was used as pig feed. Due to technical constraints, the utilization rate of my country's rice bran has not been high. The key technological innovation and industrialization project hosted by He Dongping has overcome this bottleneck problem.

He Dongping calculated the account from the reporter of the Yangtze River Daily: In theory, my country's rice output each year is about 200 million tons, which can produce about 14.5 million tons of rice bran. Tons, this number is equivalent to 14.5 million tons of soybean oil.

"Squeeze" each grain of rice has always been the persistent pursuit of He Dongping. He Dongping introduced that due to the decentralized processing of rice bran, short shelf life, and proneness, the quality of rice bran oil was poor and refined, which also restricted the development of the rice oil industry. The key to overcome this problem is to extend the shelf life of rice bran.

He Dongping and his oil and plant protein technology innovation team used fresh -keeping technology to extend the storage time of rice bran from 7 days in the past to two months. And nutritional is worth it.

He Dongping said that because the process is complex and the oil is not easy. It is a recognized problem in the industry. "In other words, it can break through the processing technology of rice oil and the refining of any vegetable oil."

In more than 20 years, breakthroughs are made in more than 20 years

Let people eat oil more assured

He Dongping, born in the Jianghan Plain, grew up in the "Hometown of Fish and Rice", but did not know that rice bran could squeeze oil before. He recalled that when he was a kid, he often ate cotton seed oil. In the era when the supplies were short, "the family always saved oil and saved."

In 1977, when the college entrance examination was resumed, He Dongping, who was decentralizing in the countryside of Hanchuan, became the first college candidate. He was admitted to the oil and oil engineering department of the Grain and Oil Engineering Department of Zhengzhou Institute of Technology (now Henan University of Technology).

The first lesson of freshmen, Chen Wenlin, the director of the new student, taught what oil is. He Dongping remembered a sentence from Professor Chen's two -hour speech -the care of the oil, which was promising.

This pair of fate and apprentices will work for more than 40 years in the future and publish "History of Chinese Oil Make".

Three years later, 23 -year -old He Dongping entered an internship of a fat factory in Songjiang, Shanghai. On the first day of entering the factory, he was attracted by two pots of oil on a display cabinet. One pot is rice oil produced in Japan. At that time, Japanese rice bran refining technology was at the forefront of the world. He Dongping recalled that after watching a series of technical parameters, he "took a breath": "How did this do?"

At the end of the 1990s, with the improvement of people's living standards, people's requirements for edible oil were getting higher and higher, and the key technologies for breaking through rice oil processing were put on the agenda.

He Dongping and his innovation team began to attack. In order to solve the shelf life and nutritional retention of rice bran, it is necessary to test it with six indicators such as taking off acid, decolorization, dehydration, and dehydration, and there are dozens of subdivided projects in each indicator. The adjustment of the environment and a single parameter will affect other values.

Following He Dongping after reading the graduate student and then returning to the innovation team as the person in charge, I remembered that everyone in the team was soaked in the laboratory to record and analyze the data day and night.

In 2007, the edible oil manufacturer Yijialili built the rice oil processing plant in Jiamusi, Heilongjiang. He Dongping's team began to work together with the school and enterprises, walked through countless detours, did thousands of trials, and returned many times. "Exploration is like this, there is always a price." He Dongping said.

He Dongping, who is rarely wearing a formal dress, left a formal photo in the Hongshan Auditorium. On April 26, 2019, at the Hubei Provincial Science and Technology Award and Scientific and Technological Innovation Promotion Conference, his key technological innovation and industrialization project of rice oil processing won the first prize in Hubei Province Science and Technology Progress. Today, in He Dongping's hands, there are more projects waiting for him to break through.

He Dongping said frankly that behind the years of research, behind a number of technical breakthroughs, the "good currency" successfully expelled the "inferior coins" and caused inferior oil to lose the market. He has also received many interests and threats from interest groups. "The road under your feet, since you choose, you will never go back."

From "edge" to "center"

Let the fat career succeed

In the East and West Lake Hui'an Avenue, a large van with a full -loaded rice noodle oil product departed from the park of Yijieli (Wuhan) Grain and Oil Industry Co., Ltd.

This new park enters the debugging stage in February this year. After production, it can achieve an annual processing volume of 180,000 tons of rice oil pressure squeezing and 60,000 tons of rice oil refining an annual processing volume of 60,000 tons.

According to statistics, He Dongping's team's rice oil processing technology has been promoted to dozens of companies such as Hubei, Heilongjiang, Henan, Anhui, Zhejiang, including 9 companies including Yijiali (Harbin), which has sold more than 10 billion yuan in the past three years. The new output value was 1.589 billion yuan, and the new profit was 107 million yuan.

"In the past, the refining technology of rice oil was only Japan, and now we also have the same technology." The relevant person in charge of Yili Kerry said that today China's rice oil has also been exported to Japan, and it has won "International Rice Oil Quality Awards.

In the summer vacation, He Dongping was not idle for a day, and his students were busy with him. Zhang Yanyan, who was about to rise into a junior, did not go home and followed He Dongping's team for experiments. He Dongping is very optimistic about this 20 -year -old young man.

At that time, when the college entrance examination volunteer was required to fill in the consultation, Zhang Yanyan and his mother came here and taught He Dongping a lot of questions about oil. He Dongping not only answered one by one, but also gave the young man Professor Chen Wenlin: "The oil career is greatly available."

The young man in front of him allowed He Dongping to return to the freshman lesson more than 40 years ago. He had to encourage more aspiring youths to show his fist in this world like the teacher Chen Wenlin.

He Dongping recalled that as early as 1986, he published his first paper "A Emerging Edge Discipline -History of Chinese Oil Make", and that year, the number of oil practitioners in my country was only 300,000. Today, there are 1,500 oil factories above designated size in my country, with more than 20,000 large and small oil factories, about 1.3 million people, and more young people joining them. He Dongping felt that he was no longer "edge."

A few years ago, He Dongping read a autobiographical work of Fan Jinshi, the dean of the Dunhuang Research Institute, "My Hearts is Dunhuang". The story across time and space has been touched by He Dongping. He said, "In my life, the heart is the oil."

Small knowledge >>>

"Professor Oil" teaches you to eat healthy oil:

1. Be sure to go to the regular supermarket and choose the edible oil for regular packaging. It is best to finish eating oil that year.

2. Do not eat the same oil for a year. It is best to buy 500 grams or 1000 grams of packaging and replace one edible oil every month.

3. Common peanut oil, corn oil, rapeseed oil, etc. have their own characteristics, but they are the healthiest to eat.

4. Conditional families can choose linen seed oil, which can be mixed with other edible oils.

5. Save the oil at low temperature to avoid sunlight.
