　　【Aspects of Big Food Technology】

　　"Soybean oil accounts for almost half of my country's edible oil consumption. According to my country's edible oil consumption data in 2021, soybean oil accounts for about 44%." Recently, Wang Ruiyuan, chief expert of the China Cereals and Oils Association and honorary president of the Oils Branch, told Science and Technology Daily The reporter introduced a set of data.

It can be seen that to this day, soybean oil is still the favorite of Chinese people.

But he also said, "my country has a large population and is a big producer and consumer of edible oil. However, the self-sufficiency rate of domestic edible oil is less than one-third."

　　"This year's Central No. 1 document proposes to vigorously implement the project to increase the production capacity of soybeans and oilseeds; it is a national strategy to increase the supply of domestic oilseeds in my country and ensure the safety of edible oil. Pack more Chinese oil!" Wang Ruiyuan said with relief.

　　Taking the lead in expanding 10 million mu of planting, Heilongjiang adds confidence to the stability of the "oil bottle"

　　This year, the national soybean oilseed area is planned to increase by more than 22 million mu.

As a high-quality soybean production and supply base in my country, Heilongjiang accounts for more than 40% of the country's annual soybean planting area.

Responding to the call of the state, Heilongjiang bears the brunt of the project, vigorously implementing the soybean production capacity improvement project, and insisting on the two-wheel drive of expanding area and bill of lading.

It is proposed that more than 10 million mu of soybeans will be expanded in 2022, and the soybean planting area in the province will reach 68.5 million mu, with a total output of 17 billion catties.

　　"During this period of time, my mobile phone was about to explode, and customers were calling to buy high-oil and high-yield Hei Nong 87 soybean seeds. Unfortunately, I have less preparations, and there is still a gap of more than 4,700 tons that cannot be implemented." April 10, Heilongjiang Li Yanxin, general manager of Tianyou Seed Industry Co., Ltd., said happily, "Heinong 87 varieties have strong adaptability and comprehensive performance. The country has called for the expansion of soybean planting, and growers in many places have purchased Heinong 87."

　　"The highest oil content of Heinong 87 is 23.6%, which is more than 3 percentage points higher than that of ordinary soybeans. As an oil plant, it can greatly improve the yield of edible oil." Lai Yongcai, vice president of the breeding team of Heilongjiang Academy of Agricultural Sciences, said proudly.

　　The expansion of soybean planting in Heilongjiang has the support of good seeds, good laws and good fields, and the assistance of scientific and technological personnel.

　　This spring, due to the impact of the epidemic, scientists and technicians in the soybean field in Heilongjiang have turned to the cloud to teach farmers the secrets of technology for expanding planting and increasing production and preparing for spring ploughing through live webcasts.

With the remote guidance of scientific and technological personnel, large planters have taken the initiative to increase the area of ​​soybeans.

　　At the same time as soybean expansion, rapeseed, sunflower, peanut and other oil crops are also steadily expanding in major producing areas across the country.

The agricultural science and technology personnel in the corresponding fields have approached the main battlefield for soybean oil plant expansion and production.

So far, my country has taken a solid first step in improving soybean oil production capacity and self-sufficiency rate.

　　Technological breakthroughs and technological empowerment to ensure quality and safety

　　The guarantee of plant expansion and production increase is the safety of raw material supply.

And edible oil processing companies have explored the use of technology to ensure the quality and safety of "oil bottles".

　　Now, when you walk into a large supermarket in Heilongjiang, you can see the domestic soybean oil "Jiu San soybean oil" on the shelf. Scan the QR code on the oil bottle with your mobile phone, and you can know the "past life and present life" of this oil bottle.

　　According to Luo Shunian, general manager of the R&D and Quality Management Department of Jiusan Food Co., Ltd., a subsidiary of Jiusan Cereals and Oils Industry Group, the company has invested 5 million yuan in the construction of product traceability projects. Consumers can learn about each barrel by scanning the QR code of the product. The raw materials, quality inspection and production of soybean oil allow consumers to eat good oil with confidence.

　　"The risk monitoring system established by the company not only includes the supervision of risk items required by the state, but also adds a number of risk indicator monitoring with reference to infant food and EU food standards to ensure the absolute safety of products." Luo Shunian emphasized.

　　"Our team is targeting soybeans, rapeseeds, peanuts and other bulk oils and fats with low resource utilization, loss of nutrients, associated hazards, low-value products, serious homogeneity, high energy consumption, water consumption and emissions, and low equipment intelligence. On April 11, the executive director of the National Soybean Engineering Technology Research Center, Professor Li Yang of Northeast Agricultural University, introduced to the Science and Technology Daily reporter: "Our research goal is to achieve low-consumption green oil processing, safe and nutritious products. Achieve self-reliance and self-reliance of oil technology."

　　From excessive processing to moderate processing, industry-university-research cooperation in the field of edible oil has achieved breakthroughs in both concepts and technologies through the blessing of science and technology.

　　As early as 2012, Professor Wang Xingguo of Jiangnan University and his team, together with Yihai Kerry Golden Arowana, began to study the elimination of trans fatty acids in edible oil. While abandoning the excessive processing technology, they proposed a new edible oil processing mode - green, precise and moderate processing technology.

The new process allows the "oil bottle" to retain as many nutrients as possible, remove harmful ingredients, and achieve a "zero-reverse" breakthrough. The retention rate of beneficial ingredients such as vitamin E and phytosterol is as high as 80%, which meets consumers' demand for healthy nutrition. demand.

　　This process can reduce steam consumption by 69%, waste water discharge by 78%, and carbon emissions by 30% during processing, with significant energy saving and emission reduction effects.
