Ding ~ all the knowledge about soybean oil is here!

Last week,

We told you a little knowledge about soybeans.

Today, small farmers continue to talk to you about soybean oil.

As we all know, soybean is a frequent visitor to people’s dining table because of its rich nutrition, and soybean oil is also an important cooking material that many families like. So, how is soybean oil extracted? What are the nutritional values of soybean oil? Today, we invited Liu Changsheng, an expert from the Institute of Oil Crops, Chinese Academy of Agricultural Sciences, to answer your questions one by one.

I don’t know if you are as curious as a small farmer,

Delicious soybeans,

How did it "change" into oil?

Extraction of soybean oil

According to experts, as the name implies, soybean oil is extracted from soybeans, and there are many extraction methods, among which squeezing and leaching are common.

Squeezing mode:By adopting the physical squeezing process, the oil is produced by physical squeezing in the production process, and there is no additional additive, so the crude oil is of high quality, complete in color, fragrance and taste, and retains various nutritional components in soybean, with high nutritional value.

Leaching mode:Soybean leaching oil was obtained by the principle of oil leaching with oily solvent.

Because of the low oil content of soybean, soybean oil can be extracted well by one-time leaching process, and the residual oil of soybean meal after leaching is below 1%. Leaching method is common in large processing plants.

Nutrition of soybean oil

After soybeans are made into soybean oil,What is the nutritional content?

Soybean oil has a long edible history and rich nutrition, especially the fatty acid composition in soybean oil. In soybean oil, linoleic acid content is prominent, which can reach 50% ~ 60%. Linoleic acid is an essential fatty acid, which is beneficial to human health. In soybean oil, the content of oleic acid (unsaturated fatty acid) is 20%, and the content of saturated fatty acid is low, only 15%.

Secondly, there are trace elements in soybean oil (also known as lipid companion), which is rich in vitamin E, phytosterol and lecithin, which is very beneficial to human health.

Is soybean oil suitable for everyone?

Experts say that the human body needs three nutrient elements (carbohydrate, protein and fat), and we need them every day in our life, so a proper intake of soybean oil (fat) can meet human needs.

However, excessive intake of soybean oil is not recommended for people with basic diseases, such as biliary tract diseases (gallstones, cholecystitis, etc.); People with "three highs" (hyperlipidemia, hypertension and hyperglycemia) should not take too much; People with intestinal system deviation should not take too much.

What is the best way to eat soybean oil?

Soybean oil is suitable for any cooking method of Chinese food.

If it is used for high-temperature frying, you can buy soybean oil specially used for frying.

However, the soybean oil squeezed physically has more comprehensive nutrition retention and is more suitable for cold salad. If it is used for cooking, it is necessary to control the oil temperature and not stir-fry at high temperature to avoid nutrient loss caused by too high oil temperature.

How to choose soybean oil?

1, look at the quality level

According to Soybean Oil (GB/T 1535—2017), the finished soybean oil is divided into three grades according to its quality index.

Source: GB/T1535-2017 Soybean Oil

The first-class edible oil fume has high point, clear color, light fragrance and taste, and less oil fume when cooking, which is suitable for high-temperature stir-frying and deep-frying.

The third-grade edible oil is just the opposite, because it is moderately processed, so it has a strong flavor and taste.

2, look at the processing technology

Squeezing oil separates oil from raw materials by physical method, which retains more nutrients, but the cost of squeezing process is higher and the price is more expensive. The extracted oil has high oil yield, low production cost and relatively cheap price.

3, look at the color depth

The color of soybean oil is not directly related to the quality of oil, but to the variety of soybean. Basically, the color of soybean oil is light yellow to golden yellow, and the color of soybean oil squeezed by some varieties is relatively dark. If the color of soybean oil is very light, it may be decolored.

It is worth noting that do not buy bulk oil of unknown origin.

Is it a rumor that soybean oil contains trans fats?

Whether trans fat is contained in oil is related to the processing technology. If oil is pressed at low temperature, there is basically no trans fat. If it is treated at high temperature during processing, a small part of polyunsaturated fatty acids in soybean oil may change from cis to trans fatty acids, so it may change during this processing.

Of course, you don’t have to worry. In fact, except soybean oil, most vegetable oils will have this possibility during processing, but the trans-fatty acid content is not high. The study found that the trans-fatty acid content in refined first-grade soybean oil is mostly below 0.2%, which will not affect the body.

Edible oil consumption suggestion

Control total intake

According to the recommendation of Dietary Guidelines for China Residents (2022 Edition), the daily edible oil intake of residents needs to be controlled between 25 and 30 grams. For health reasons, this recommended value is recommended to be strictly observed.

Control cooking oil temperature

Don’t wait until the oil smokes before putting the ingredients into cooking, because the edible oil rich in polyunsaturated fatty acids is not recommended for high-temperature cooking to avoid excessive oxidation.

Control cooking methods

Excessive intake of edible oil may cause metabolic diseases, and delicious dishes can be cooked with less oil. The cooking method should be mainly steaming, boiling, stewing, stewing and frying, with less frying and frying, and air fryer can be used instead of frying.

Why did you come？ Peng Yuyan and Zhang Aijia talk about the reasons for participating in ＂Tropical Past＂

1905 movie network news　After the film, which was produced by the producer, directed, led by, starred in, starred in, starred in, starred in, starred in,, starred in, and starred in, from the official announcement to the national release on June 12, 2021, the topic trendiness ranked first in the entertainment hot search list, which shows the audience’s expectations for the film. With the heavy official announcement, "Tropical Past" released a special "Versailles" lineup. Peng Yuyan, Zhang Aijia, Wang Yanhui and many other powerful actors faced the camera and analyzed for the first time why the high-end cast "came". The film director Wen Shipei also sighed: "It’s really dreamy to have such a lineup."

Peng Yuyan praised the script "powerful" Zhang Aijia shouted "interesting"　　

Producer Ning Hao called "Once Upon a Time in the Tropics" enjoyable and temperamental

The movie "Once Upon a Time in the Tropics" has been fully upgraded and will be released nationwide on June 12, 2021. Not only has it officially entered the Dragon Boat Festival, but also the heat of the summer season has been detonated a week earlier. After the film’s upgrade information was announced, some viewers said: "Wait for the Dragon Boat Festival"; "This summer is dry". As early as the film announced the cast, many audiences were curious: what is the charm of such a big-name heavyweight lineup that gathered in "Once Upon a Time in the Tropics"? Recently, the film released a special "Versailles" lineup. Peng Yuyan, Zhang Aijia, Wang Yanhui and other powerful actors explained the reasons for joining the camera for the first time. Peng Yuyan said bluntly: "It is very different from the scripts I have read in the past, and the most intuitive feeling is that it is very powerful." Zhang Aijia sold it off: "The script is a little ambiguous, a little strange, a little curious, I think it is very interesting." Wang Yanhui, who has extensive acting experience, said frankly: "It is one of the more difficult things for me to create over the years."

In addition to the attractive script, Ning Hao, the executive producer of "Once Upon a Time in the Tropics", also attributed the film’s unique temperament to attracting a lot of big names. "Director Wen Shipei is a director with aesthetic characteristics," he said. "He can put together good actors and exert a very special temperament." The second half of the special is closely combined with the atmosphere interpreted by the film. The background music is beautiful, allowing the film to be extended beyond the plot.

"Once Upon a Time in the Tropics" is more than just a crime genre　

Peng Yuyan explains the issue of character growth

When it comes to newcomer director Wen Shipei, several leading actors invariably mention keywords such as "special" and "detail" in the interview. The special feature of "Versailles" in "Tropical Past" involves director Wen Shipei’s use and discussion of details on the set. One is that he uses Blackfish as a metaphor for Peng Yuyan’s role as Wang Xueming, and the other is that he and Peng Yuyan discuss the relationship between Shadow Killer and Zhang Yu. Although it is like peeking into the leopard, it can make people feel the different temperament and unique aesthetic pursued by the film. Zhang Aijia said: "Director Wen Shipei is a very philosophical child, he cares about some small details, which is what we like about him very much." Mr. Wang, for his part, said the film was not about reality: "There is a fruity aroma in red wine, or maybe it is mixed with rocks."

In addition to the details, the special also vaguely reveals the close connection between several characters. Peng Yuyan also expressed from the side one of the topics covered by the film "Tropical Past": how people should face up to their own past and how to grow up. This is undoubtedly the human echo that the film pursues outside the crime suspense genre. Speaking of working with such a heavyweight cast, director Wen Shipei is also very emotional: "For any new director, it is dreamy and lucky to meet such a few actors in his debut film."

In the second issue of ＂China Star Jump＂, the three goddesses 10-meter platform shocked the audience.

　　Killer, the actress’s first jump in the 10m —— As the first contestant, Killer, a natural female voice, made her competitors fidgety when she started to jump. She directly stepped onto the 10m platform with her back to the pool, and the difficulty rose to another level. After almost flawless falling into the water, Killer became the first person in all diving programs.

＂Hot Search＂ won the Golden Rooster domestic new film exhibition, which was most anticipated by the audience. Xin Yukun did not play suspense to dig deep into human nature.

A few days ago, the film "Hot Search" appeared at the Golden Rooster Film Festival and held a screening event. Director Xin Yukun, producer Wang Hongwei, starring Zhou Dongyu, Song Yang and Justin attended the post-screening interaction to share the behind-the-scenes story of film creation with the audience. In this film festival, Hot Search won the 36th China Golden Rooster Award, and the domestic new film exhibition was the most anticipated feature film by the audience.

The film "Hot Search" tells the story that Chen Miao (Zhou Dongyu), the editor-in-chief of the media, penetrated the traffic password, created an explosive article and rushed to the hot search, but indirectly boosted the female student of the bully to jump off the building. At this time, Chen Miao accidentally discovered the help information sent by a female student and involved a sexual assault case. Chen Miao’s partner He Yan (Song Yang) and investor Peng Yue (Justin) are involved in it. Public opinion has turned many times, what kind of interest chain is hidden behind the incident, and a public opinion war for the weak has started … The film will be officially released on December 1.

Xin Yukun, the director of Heart Labyrinth and Silent Burst, didn’t choose to make a fuss about suspense structure this time, but focused on the network theme closely related to the present, and explored the complex humanity behind the "network public opinion war". Xin Yukun said that in such a story, the suspense skills full of design will weaken the sense of reality. "I am willing to sacrifice suspense and impress the audience with authenticity.".

At the scene, producer Wang Hongwei said that movies have the responsibility to show social phenomena. Xin Yukun also said, "What happened in the network in recent years is the power of awakening, and it is necessary to be recorded and transmitted.". "The film can’t tell all the complicated causes behind the network, but I hope it can help you sort out the whole story and improve your ability to identify the truth."

This time, Zhou Dongyu plays Chen Miao, the editor-in-chief of the media. At the scene, Zhou Dongyu also shared his love for the role. "Chen Miao believes that one thing will die to the end, and this tenacity in her body particularly attracts me.".

Song Yang plays He Yan as a "middle-aged social animal" trapped by interests. Song Yang said frankly that the middle-aged crisis dominated the choice of what to say, and the reality and pressure made him constantly compromise, and he was powerless to the truth. Yuan Hong played a "perverted and bad" villain. Peng Yue held power and did whatever he wanted. Justin couldn’t help but say "I want to beat him!"
