Ionizing radiation effects on food vitamins - A Review. Ionizing radiation has been widely used in industrial processes, especially in the sterilization of medicals, pharmaceuticals, cosmetic products, and in food processing.

Introduction to Food Irradiation

The RS is currently being used in 2 different industries which are food irradiation research and insect population control. The RS and RS V are currently being used in 2 different industries which are food irradiation research and insect population control. In Europe, as in many countries of the world, the irradiation of food is an acceptable method of food preservation. The European Union EU approves which foods can be irradiated and to what range of radiation doses. It requires that all irradiated foods be clearly labeled and that market-level inspections are completed to ensure compliance with the regulations.

To develop an alternative pasteurization process for the spicy beef jerky SBJ , it was treated with irradiation doses of 0, 0. The results showed that lightness, drip loss, and off-odor of SBJ increased, while the hardness, chewiness, gumminess, color preference, and taste of SBJ decreased with the increase in irradiation dose. The possible reason for these quality changes might be due to the free radicals produced by irradiation. This speculation is supported by the decrease of the content of capsanthin and the increase of the content of TBARS of SBJ with the increase in irradiation dose. Spicy beef jerky SBJ is a popular meat product in China, which is being consumed or mostly being bestowed as a snack food.

Irradiation does not make foods radioactive, compromise nutritional quality, or noticeably change the taste, texture, or appearance of food. In fact, any changes made by irradiation are so minimal that it is not easy to tell if a food has been irradiated. Food irradiation the application of ionizing radiation to food is a technology that improves the safety and extends the shelf life of foods by reducing or eliminating microorganisms and insects. Like pasteurizing milk and canning fruits and vegetables, irradiation can make food safer for the consumer. The Food and Drug Administration FDA is responsible for regulating the sources of radiation that are used to irradiate food. The FDA approves a source of radiation for use on foods only after it has determined that irradiating the food is safe. National Aeronautics and Space Administration NASA astronauts eat meat that has been sterilized by irradiation to avoid getting foodborne illnesses when they fly in space.

This hour long video tape is a review of the strengths and limitations of food irradiation, the regulatory environment and rationale for its use. It can be used as a background for the educator or as a stand alone educational piece with interested students or consumers.

Though accurate at last review, it is no longer being updated.

David Acheson, J. Although the United States food supply is generally considered one of the safest in the world, foodborne illnesses remain a concern. Each year, millions of Americans become ill and as many as die from foodborne infections.

Food irradiation is the process of exposing food and food packaging to ionizing radiation , such as from gamma rays, x-rays, or electron beams, without direct contact to the food product. Some bonds rupture and produce free radicals which are highly reactive and unstable. They instantaneously rejoin with neighboring compounds and the results are called radiolytic compounds. Food irradiation is permitted in over 60 countries, and about , metric tons of food are processed annually worldwide. In Austria, Germany, and many other countries of the European Union only dried herbs, spices, and seasonings can be processed with irradiation and only at a specific dose, while in Brazil all foods are allowed at any dose.

 Тебе следовало бы работать в полиции, - улыбнулся Стратмор.  - Идея неплохая, но на каждое послание Танкадо, увы, поступает ответ. Танкадо пишет, его партнер отвечает. - Убедительно.  - Сьюзан нахмурилась.  - Итак, вы полагаете, что Северная Дакота - реальное лицо. - Боюсь, что .

Я из канадского консульства. Я пришел, чтобы убедиться, что с вами все в порядке. Внезапно в гимнастическом зале, превращенном в больничную палату, повисла тишина. Старик внимательно разглядывал подозрительного посетителя. Беккер перешел чуть ли не на шепот: - Я здесь, чтобы узнать, не нужно ли вам чего-нибудь.

Она нервничала, гадая, сколько еще времени продержится ТРАНСТЕКСТ. Сирены продолжали завывать; то и дело вспыхивали сигнальные огни. Тремя этажами ниже дрожали и гудели резервные генераторы. Сьюзан знала, что где-то на дне этого погруженного в туман подземелья есть рубильник. Кроме того, она понимала, что времени почти не оставалось.

Всем известно, что невзламываемый алгоритм - математическая бессмыслица. Хейл улыбнулся: - Ну конечно… Принцип Бергофского. - А также здравый смысл! - отрезала .

Интуиция подсказывала ей спасаться бегством, но у нее не было пароля от двери лифта. Сердце говорило ей, что она должна помочь Стратмору, но. Повернувшись в полном отчаянии, она ожидала услышать шум смертельной борьбы на полу, но все было тихо.
