An overview of effects of gamma radiation on the biological, physicochemical and nutritional parameters of oilseeds and oils

Purpose Gamma irradiation is a non-thermal method for prolonging the shelf-life of foods and it is a possible alternative technology for oilseeds. After harvest, the development of pests and microorganisms, as well as the reactions caused by enzymes reason numerous problems in the oilseeds. Gamma radiation is one of the methods that could inhibit undesired microorganisms, but it can also change the physicochemical and nutritive characteristics of oils.Conclusion This paper is a brief review of recent publications on the effects of gamma radiation on the biological, physicochemical and nutritional parameters of oils. Overall, gamma radiation is a safe and environmentally friendly method that improves the quality, stability and safety characteristics of oilseeds and oils. In the future, there may also be many health reasons to produce oils using gamma radiation. Investigation of other radiation techniques such as x-rays and electron beams have a good potential once the specific doses that would free them from pests and contaminants have been identified while conserving the benefits without altering their sensory properties.
