Is it important for you to have good nutrition? I sure hope so because good nutrition means better life in general. But, as important it is to consume that nutrition, it is equally imperative to know where it is coming from, what chemicals have been sprayed on them, whether they are organic as they claim to be and what safety measures one must take before consuming them. However, we don’t get those answers as even if we acquire them from a vegetable vendor or order online, they all claim them to be nutritious.

Addressing one such concern, the Food Safety & Standards Authority of India (FSSAI) has issued a statement saying that food products that have been treated with ionising radiation must be marked.

WHAT IS THE PROCESS OF IRRADIATION?

Ionising radiation or irradiation is the process that involves exposing of the organic foods such as fruits & veggies to the ionising radiation like ultraviolet radiation, gamma rays, X-rays or electron beams to fulfil certain objectives such as-

  • Increasing shelf-life,
  • Killing of insect & pests
  • killing of parasites & pathogens, and
  • Microbial spoilage

Here are eight things you must know about the ionising radiation process and the marker that you must look out for a while buying irradiated products.

1. According to the latest statement issued by the FSSAI, all food products that have undergone irradiation must carry the ‘Radura’ mark along with the tag ‘treated with radiation’ or ‘treated by irradiation.’

Radura is an international symbol, usually green in colour and resembling a plant in a circle. The word “Radura” is derived from radurization, in itself a portmanteau combining the initial letters of the word “radiation” with the stem of “durus”, the Latin word for hard, lasting.

2. Based on the requirements (as per dosage), the applications of food irradiation can be classified as low dose, medium dose, and high dose.

3. The process of irradiation includes exposing food products such as fruits and vegetables to ionising radiation like gamma rays, X-rays or electron beams to achieve certain technological objectives.

The FSSAI says that these objectives “include [an] extension of shelf-life, destruction of storage and quarantine insect pests, and killing of parasites, pathogens, and spoilage microorganisms.”

4. As compared to chemicals and fumigants, irradiation is much more effective and does not leave any harmful residue in food. It is equally suitable for both bulk as well as pre-packaged food and is a physical, non-additive process that causes minimal change in it.

5. Several misconceptions about the process have made consumers wary of irradiated food products.

However, the FSSAI assures that this is a safe process that “have inbuilt safety features that prevent human exposure to radiation.”

6. Several international entities, including the World Health Organisation (WHO), have clarified the misconceptions that may occur with consumers or even policymakers.

At high energy levels, ionising radiation can make certain constituents of the food radioactive. Below a certain threshold of energy, however, these reactions do not occur. On the basis of experimental studies and theoretical estimates, in 1980, the Joint FAO/IAEA/WHO Expert Committee on the Wholesomeness of Irradiated Foods recommended restricting the radiation sources used in food processing to those with energy levels well below those that induce radioactivity in treated food,” observes the WHO.

7. Currently, food irradiation is permitted in over 60 countries including the USA and China. Apart from fruits and vegetables, spices, dry vegetable seasonings, meat, meat products, herbs, and herbal products are the major commodity groups where this technology is used.

8. To clarify the difference between irradiation and radioactive food further, FSSAI says “Radiation processed foods are those that have been exposed to radiation to bring about the desired technological benefits. Radioactive foods, on the other hand, are those that become contaminated with radionuclides, for example during nuclear accidents. Contamination with radionuclides never occurs during radiation processing.”

The FSSAI guarantees that this process causes no harm to the consumer. To ensure that people are well informed about what all processes the food they purchase has undergone, they have made it mandatory to have the Radura mark and tag on the products.

So the next time you are out there buying groceries, make sure that you are well versed with the guidelines issued by FSSAI. Do not forget to look out for the sticker as it will keep you aware about the food which you are consuming. Also, from next time you don’t have to get your answers from a vegetable vendor or online website, you can do it by yourself.
