Having demonstrated the wholesomeness of irradiated food, then scientists had to prove that nutritional impact of food irradiation was minor. Animal testing, vitamin and amino acid measurements in irradiated food, and no longer in solutions, have demonstrated that recorded changes, at commercial doses i.e. 1 to 10 kGy did not present any hazard. It must be noted that sensory qualities of radiosensitive food products like milk, are altered well before nutriments.
