**2.4 Irradiation treatment**

Another most commonly reported physical decontamination technology is γ radiation. The use of γ radiation has been reported on some kinds of food substrates including groundnuts, grains, palm juice, soybean, and animal feed. Irradiating the food products with a γ-ray source is moderately effective with an average percent reduction of 65% at high irradiation dose [14–20]. Gamma irradiation is a promising method to improve the safety and economy of moderately fungi-damaged feedstuffs.
