"Self -heating Rice" enlarge 1000 times!I didn't expect this scene ...

For a long time, the Qianjiang Evening News Chronicles news column "Just Fan said" returned strongly.

When it was hot, many people were too lazy to cook. Like the recent temperature, it is convenient for food and prefabricated vegetables to consume.

This year, the prefabricated dishes are out of circle, and even some stars live broadcast to sell prefabricated dishes, creating a lot of performance.

In fact, almost everyone has consumed prefabricated dishes, and version 1.0 is represented by instant noodles.

Because of the epidemic and other reasons this year, the upgraded version of "Self -heating Rice" is also given a cooked vegetable bag+rice bag. The rice bag inside is dry and the particles are clear. Essence

Have you ever eaten, what do you think of it?

Recently, a friend who had been engaged in rice breeding for more than a decade of rice breeding, took the child and his classmates outings for more than ten years. For the first time, he tasted the self -heating rice given by the other parents. I stock it a lot, I feel the taste is good, and I still repurchase. "

Isn't it natural rice in the rice in the rice?

With questions, the hourly journalist ran seven or eight brands of self -heating rice, and found Shen Lirong, a professor of nutrition at Zhejiang University. He is an authoritative expert in the food processing and business safety field of our province.

Teacher Shen, who is particularly "particular" to eat, said: "Self -heating rice is a prefabricated category. At present, there is no national standard, only local and corporate standards."

If you want to figure out what the rice is in the rice, you need to experiment to analyze it.

After being introduced by Teacher Shen, the reporter found two units of Zhejiang Academy of Agricultural Sciences and Zhejiang Guozheng Testing Technology Co., Ltd. for two groups of experiments.

Self -heating rice is enlarged by 10,000 times,

We see the broken starch structure

The natural rice we eat was refined and removed most of the species of skin and germ. The starch structure of rice is similar to the brick house we live in, which are piled up by "bricks".

Natural rice electron microscopy

This is the rice starch structure shot by scanning electron microscope in the Public Laboratory of Zhejiang Academy of Agricultural Sciences, that is, the appearance of rice after 10,000 times.

After the rice of thermal rice is enlarged by 10,000 times, it looks a bit like a gravel beach by the river, and the size is different. They are made of starch restructuring and the original starch structure has been destroyed.

Self -heating rice electron microscopy

Teacher Shen said that looking at the photos is clear, natural rice and spontaneous rice starch structure are completely different. Obviously, self -heating rice is not natural rice, it is artificial rice.

Under the 20 times optical microscope, we can see that the shape of natural rice is round and round, and the tip of the tip is the location of the rice germ. If there is no refined rice, the tip of the tip is its germination place.

Natural rice

Artificial rice

The rice in the heating rice is similar to the appearance of rice, but if you look at it by 50 times, you find that the two ends of the rice are round, and the detailed characteristics of those natural rice do not exist.

A staff member of the wholesale market at the Hangzhou Grain and Oil Logistics Center said that the market has been in the market for many years. Who can recognize it at a glance, the rice in the heating rice is not natural rice. "Because their two ends are the same shape, they use starch and other ingredients to make it by machine shaping."

Spontaneous rice

The hourly news reporter searched the Internet and found that there are many manufacturers of manufacturers of artificial rice processing equipment on the Internet. The price of a machine usually costs tens of thousands of yuan.

Yu Yonghong, director of the Genergy Inspection Office of the Rice and Rice Product Inspection Center of the Chinese Rice Research Institute, is one of the authoritative experts in the field of rice quality in my country and even the international rice quality.

"Usually, the refined processing of the oil in the natural rice, the oil content of 0.5%-1%. Rice-breed skin oil is higher, and the brown rice oil content is usually 3%." After watching these products, I think it is really not natural rice. "This artificial rice has destroyed the original nutritional ingredients of natural rice."

"Single and double glycerol fatty acid ester" on the self -heated rice packaging,

What is it?

The packaging instructions for self -heating rice show that the most important ingredient in the self -heating rice is rice, as well as single -double glycerin fatty acid, and some also add other starch. What is "single -double glycerin fatty acid ester"?

"The ingredient of a single double glycerin fatty acid ester is an emulsifier that exists in foods, cakes, bread and other foods to improve the taste of food." Professor Shen Lirong of Zhejiang University said that patients with diabetic and patients with abnormal blood lipids, patients with abnormal blood lipids, and patients with abnormal blood lipids. Try to consume less foods containing single -double glycerin fatty acid. "This kind of substance can increase the fatty acid content in the patient's body, so it has a certain increase in blood lipids and blood sugar in patients."

Some self -heating rice ingredients are also corn starch.

"The purpose of adding starch to artificial rice is to improve the taste. Previously, it did use potato starch to process artificial rice." Shen Lirong said.

Professor Cheng Fangming of the Agricultural College of Zhejiang University began to engage in rice science research in the 1980s and was the first batch of scientists in the field of rice quality improvement in my country. In addition to starch in natural rice, there are various vitamins and various minerals and trace elements.

"There is a 'steamed valley rice', which is the first steaming of rice, and then decarning; not as white as the rice we eat, with a kind of skin brown, it can be understood as a" back pot rice ", because the second cooking It mainly lost is the essential vitamin B family. In the artificial rice that repeatedly heated processing, the nutritional content of the loss may be more. "Cheng Fangming said. Add rice with rice, add starch artificial rice,

Is it really safe and healthy?

So, will manufacturers use Chen rice or spoiled rice to process artificial rice? What is the food safety in the rice in the feathers?

The laboratory of Zhejiang Guozheng Testing Technology Co., Ltd. adopted a control group experiment to make two kinds of raw rice, two supermarket pre -packaged cold rice, two kinds of spontaneous rice dumplings, the total number of colonies, Salmonella, waxybacteria, fatty acid ester, and fatty acid ester, fatty acid ester, fatty acid ester, Detection of water such as water.

▲ The test results of the two brands of thermal rice bag in the orange box

Most of the two indicators of the colonies and Salmonella in the experiment are easy to understand, and the detection data of the six samples are also within the normal range.

The indicator of wax -like spores is usually used when detecting overnight meals. For example, the temperature is high in summer. If the rice is squeezed overnight, Bacillus will exceed the standard.

The fatty acid ester is used when the rice is detected whether the rice is Chen rice. The detection data of the two self -heated rice bags we sampled is within the normal range.

In the end, Teacher Shen made an experimental summary: The self -heating rice is a prefabricated dish. There is no national standard for prefabricated dishes. Only local and corporate standards. The self -heating rice for this random inspection is acceptable, but for everyone's nutrition and nutrition Think about health, personal suggestions for these foods should be eaten as little as possible.
