Low-wavelength gamma rays carry high energy, and therefore have a higher ionic potential than other types of rays when processed. However, due to the difficulty in access to Cobalt-60 in the current market condition E-beam irradiation technology are becoming more popular. Unlike, medical devices, food products are not required to go through a rigorous validation stage. However, there are still some important criteria to consider when making the switch. 

Firstly, E-Beam irradiation technology uses a modern automatic conveyor system to transport products from the loading area to the irradiation chamber, usually box by box. Comparing, to Gamma irradiation using mainly tote boxes or pallets. It is important for the box’s dimensions are within the limit of the conveyor. 

Secondly, Due to the nature difference characteristic of Gamma ray and Electron particle in penetration into the products it is important to ensure the arrangement of bags/products are similar when performing dose mapping. Otherwise, it wouldn’t be possible to achieve the desired dose. This would require a strict commitment between service provider and customer to keep the products information secured from other customers.

Thirdly, Depending on the type of food products they would have different characteristics to paying attention to. For example, some dry herbs and spices products having concern about the color of the products to faded, brighten, or darken the products natural color. Some seafood products under certain conditions could produce different aroma when cooked compared to the control sample. There should be a thorough check with customers quality department to balancing between the change in the aroma, looks, taste of the food products and the sterility of the product.
