When rice is put on for a long time, it will become moldy and wormy. Potatoes will sprout for a few days. Vegetables are worried about pesticide residues. These problems that we often encounter in our daily lives can be solved by taking an “irradiationâ€. Huangdao District has introduced a high-tech project. Electron accelerator irradiation technology can produce high-energy radiation species. It can not only eliminate bacteria but also act as a preservative to extend the storage time of items. But is "irradiation" safe? It is understood that this technology is allowed to apply and there are currently no side effects.
Pesticide residues in vegetables, take a "photo" detoxification
Really good technology? On February 26th, the reporter visited the site of Qingdao Lafay Electronic Accelerator Irradiation Technology Co., Ltd., located in Hongshiya Subdistrict Office in Huangdao District. The general manager of the company, Han Lei, said that there are two main functions of irradiation technology. : Sterilization and modification. "The main role of food is sterilization, which produces high-energy rays, sterilizes and preserves food, degrades pesticide residues, inhibits mildew, kills insects, etc." Manager Han said that food can achieve the preservation of agricultural and sideline products. , Anti-mildew, insecticide, inhibition of germination, the purpose of extending shelf life, like rice put a long time will become mold and insects, potatoes bought a few days to grow buds, these problems can be solved by irradiation technology. "The other advantage of the irradiation technology is that it can extend the shelf life of the items and replace the effect of preservatives. Vegetable bags like instant noodles can use this radiation technology."
Irradiation can disinfect foods. How do you do it? The reporter visited the entire process of disinfection. Specifically, the goods were sent to the conveyor belt. When they entered the irradiation area, they came out and came out. It felt like they had followed up and took pictures. "This speed and radiation amount are set according to the different items. The fastest one-minute transfer is 12 meters." Manager Han said that the main thing they did in the previous period was the disinfection of chili powder, in fact, various food fields such as seafood and pet food. Can be used.
Clothes can be softened with it
Irradiation technology can also be used in medicine, medical supplies and other fields. "Pharmaceuticals are mainly Chinese herbal medicines. Some Chinese herbal medicines are prone to mildew and drug efficacy for a long time. However, irradiation technology can extend its shelf life." Manager Han said that irradiation technology can also be applied to disposable medical products. And medical packaging materials, such as surgical blades, surgical gowns, masks, blood transfusion hemostatic gauze and so on.
"In addition to sterilization, the second major role is modification, and this function can be applied to many aspects of life. Fiber-like garments can be modified by irradiation technology to be softer and more comfortable."
Manager Han said that irradiation technology can modify and color gemstones, jades, pearls, and crystals. “The molecular structure and color of high-power electron beams will change after radiation treatment, which can achieve rich color varieties and improve product quality. effect."
No side effects of "irradiation" technology
The benefits of irradiation technology are indeed many, but this technology will not produce "radiation" pollution?
Manager Han explained that “electron accelerator irradiation technology is a green processing technology without radioactive sources. This technology has clean, efficient, safe and environmentally friendly high-tech features.†In order to prove his claim, he also let reporters see A number of domestic and foreign experts’ research reports show that after decades of research, this technology is harmless to the human body.
On February 27th, the reporter specially consulted Professor Sun Qingjie of the School of Food Science and Engineering of Qingdao Agricultural University. Professor Sun told reporters that irradiation technology applied to food, medicine and other fields is allowed in China, and it can indeed play a relatively good sterilization, modification effect, can replace the role of some additives such as preservatives.
As regards food safety of irradiated foods, Professor Sun said that irradiated foods are similar to, but not identical to, genetically modified foods. The existing technical conditions did not find any side effects on the human body. "However, irradiated foods are It is required to mark and explain, consumers can choose according to their own choice."
