IA EA /RCA Food irradiation project countries, the Chinese Academy of Agricultural Sciences, Agricultural Sciences Institute of agricultural products Processing Research Institute of high - the United States to be from mid July to now, the United States to use food irradiation technology in the world. The United States did not develop a standard for the determination of irradiated food. Because of the "radiation" caused controversy: continuously irradiated food safety? Why is the food not identified? The author has long been engaged in food irradiation research, compared to familiar with the domestic and foreign research and application, through carding process food irradiation technique growth process, desire for readers were given a clear analogy explanation.
Irradiated food did not imagine the fear
Mights as well consider such a problem: a food processing techniques, will let protein structure change, fat oxidation, the breakdown of starch, vitamins out live, and so on, if the stop strange disposal can be very casual sloppy placed in death! This kind of technology has handled the food, dare to eat? If you say, it's frightening but refused to meaning touch such food "the regret, because you can only have the food to eat due to cause any kind of food processing techniques are more or less similar nutritional ingredients of the volte face. Food processing techniques can kill the pathogenic microorganisms in food, which is due to the structure of the large part that can damage the pathogenic microorganisms. It is better to change a point of view: eat it with the disposal of food, it is not to use it to treat me like I eat steamed bread, boiled noodles, high pressure cooker stew meat, steamed bread, steaming hot steam, boiled water, high pressure boiler, will not be because I eat these foods and hurt my body. Also, although the use of radiation to dispose of food can cause cancer, but the food is not harmful to the food. Think another reason food irradiation harmless, confounding the disposal of irradiated food "and" radioactive decontamination of food "nuclear explosive accident formation of radioactive dust floating in the air, fall in food, increased radioactivity levels lead to food.
Eating this kind of food is harmless and the radiation of the food is only a ray of light shining food, food and radioactive sources have no contact, not to form a clean. Can the rays of the rays cause the food to be radioactive? At present, there are 60 and cesium and cesium 137 gamma rays, which are used for food irradiation, and the electron accelerator and energy are lower than 5MeVX ray. These rays, like infrared, ultraviolet light, radio waves, visible light and other radiation, are electromagnetic waves, only a short wavelength, the greater the energy. In fact, the important elements of the food, carbon, hydrogen, oxygen, nitrogen, etc., need to be released after irradiation, it needs the energy of 10MeV, and the life of the generated isotope is unusually short. As long as 1.33MeV and 1.17MeV are based on the research results of the British scientists in 1966, 24 hours of cobalt source, the radiation is only 0.00005% of the natural radioactivity of the food itself.
The food eaten by the US astronauts is the food.
On the Chinese market to facilitate the surface (medium of vegetables and seasoning packet) chips (the spices) small packaging of flavoring, garlic, has a long shelf life of cooked meat, frozen food, cereals and other have to through irradiation treatment. Irradiation treatment must Nianye department is irradiation companies to stop, that give birth to these food manufacturers paid disposal of irradiation of trust companies, the goal is to countries request of microbial scale, such as seasoning; extended shelf life, such as the eve of the garlic restraint sprout, grain insecticidal. All of these foods are permitted by national scale and the scale of the 80 years and 90 years of the last century is the international and informative study of the basic set up a look at the other news: the United States Apollo 11 anniversary of the moon landing 40. A few of the astronauts on the moon to the moon to eat is to eat the food. The food eaten by NASA astronauts in space is also being disposed of, and the radiation dose is slightly higher than that of the radiation dose, so as to prevent the astronauts in space to suffer from food borne diseases.
Does the radiation change the nutrients of the food?
In the event of a scientific study, there are some new materials, but these new materials can be found in the heat treatment, microwave treatment, and other processed foods, or without treatment. Of all the nutrients, vitamin C is the most sensitive to radiation, but the amount of reduction is only a fraction of the practice of heating. The World Health Organization in the last century, 80 years, it was concluded that eating irradiated food does not form a nutritional imbalance.
Food irradiation food can have a carcinogenic effect on the human body?
Hundreds of plants and clinical trials are not invented food irradiation and harmless, the contain in China organized by the Ministry of health human volunteers experiments. 70s of last century, the Ministry of health before and after tissue in many provinces, municipalities and autonomous regions, municipalities directly under the central government to stop the human trials of a large number of eating irradiated food, volunteers of about 450 people. The probation time from 7 careful 15 weeks, eating irradiated food species a total of 35 species, food irradiation accounted for 19% of cooking food to 70%. To do the test of the times, the radiation of the eve of the day can eat 1 pounds. Subsequently, for the volunteers stopped including blood biochemistry, chromosome analysis, scanning of liver and kidney of the whole project to hone, are not the results of the invention. On the base of these studies, the International Food Code Commission (C CA in 1983 set up a national scale of food irradiation, followed by more than 50 countries agreed to 200 kinds of food irradiation, food irradiation began in some countries have a trade application.
Food labeling should be further education in the United States
And heating, freezing, canning and microwave other food processing techniques compared food irradiation techniques in the use of through the complete research of unprecedented, but food irradiation to enter the market still provoke patterning fee doubts. Investigate its reason, should be because of this is an atomic energy war application skills, there is also a cause of bad Association of the name of the association. On the international scale of food irradiation in the 80 years of the last century, C CA is one of the difficult points, which is the need for the identification of irradiated food. Some atomic veto can battle for organizations, departments, business cover consider agricultural products exporter was opposed to using this technique, veto to establish standard; and most of the eve of the agricultural product export and engaged in the study of scientists is actively promoting establishment of scale, and that the frozen food is not need identification: heating of food does not need identification, why only the request of irradiated food logo? Through the talks, both sides have a step back and establish international standards, but the food must be identified by irradiation, even though the food raw material has been identified by irradiation. In the product packaging to understand that "the product or the product of certain raw materials via irradiation" can give the cost of the right to know and the right to choose. After this, all the relevant international scale are requested to have a logo on the irradiated food. The state of the identification of irradiated food is also the same request, and there are judicial provisions to ensure that the performance of its forced. The coherent scale is set up but the "receiving level of the irradiated food has a serious impact on the trade of this food technology. Although there is no organization of the veto, but the impact can be seen in the near future, the country's cost of food for the people who have the same concerns. This is one of the reasons for the business is not willing to identify the cause of food irradiation. Here, since the law, why dare not perform factory scale? Since until now, the country has not set up a sound national standard of food irradiation, that is to say, there is no ability to monitor the request for food labeling, to fulfill. One might say that the set of food irradiation criteria. The job is not so simple. Internationally, there is a measure of food on the scale, can not see the food after the disposal of food can not see it, the need for a noble instrument, reagent, time consuming capacity to determine whether the food can be irradiated. Reality, international also has a lot of people doing research in this area, has also been a ministerial level scale available, there are also laboratory can to supply a few kinds of irradiated food determination techniques. Even if it is to buy millions of instruments to establish a sound of these scales, but
The cost of testing is still very high, want to know a sample to thousands of yuan. What's more, it is not the ability to detect the safety of irradiated food, but only to detect whether the request of the conformity. At this stage of the growth of the country, there is a need to deal with the effect of the food safety, so I can do it, and it is also necessary to further comment on the results of the debate.
Another way to deal with the identification results is the automatic discharge of the business scale, the identification of irradiated food. It should be to study in america.
However, the market of irradiation products are clearly identified, there are a lot of positive identification method, such as the identification of the logo written as a "Bao Guanshi product safety" irradiation to kill pathogenic bacteria, "and so on. After 2000, the United States has occurred in the United States after the occurrence of beef and spinach in the cause of food poisoning caused by pathogenic bacteria, resulting in a large amount of product recall. After these issues, scientists, businesses and officials are generally promoting radiation technology to kill the pathogenic bacteria in frozen food and vegetables in the refrigerator, can greatly decrease the incidence of food poisoning. Have seized the opportunity to promote the United States in recent years, the amount of food consumption has increased in recent years. The current media concern of food irradiation should be said further growth of food irradiation technique is a merit, disposal of trust in business more intervention may accelerate the achievement. The veil of the irradiated food has been unveiled, the merchant and the consumer to enhance communication and understanding, will make this can make the food on the table more peace of the skills, access to more general use.
