The effect of electron beam irradiation on lipid oxidation in sausages

Irradiation treatment is one of the best techniques to extend the shelf-life of meat, without emerging the nutritional properties and sensory quality of irradiated meat products. However electron -beam may cause transformations in foods but has been known as to the most easily-applied irradiation technique in food industries. Electron-beam irradiation is an environment friendly, low cost and time effective alternative to other decontamination technologies. Lipid oxidation could produce of irradiated meat. This study aimed at evaluating the state of lipid oxidation of irradiated sausages. Its findings could help the control, improve food safety and quality properties to food industries.
Sausages were purchased in a local supermarket, minced sausages blended for thiobarbituric acid reactive substances (TBARS) analysis and divided into 25 g pieces. The samples including one control group and four case groups. Packaged sausage were exposed at doses of 0 (control), 1, 2, 3 and 5 kGy and analyzed on various days 0, 5, 10 and 30.
Thiobarbituric acid reactive substances (TBARS) has increased as time goes on (P Utilizing of Electron-beam irradiation in low doses does not have significant difference on lipid oxidation. Irradiating of meat products by addition of antioxidants can minimize or avoid the development of rancidity.
