Table 3. Sterilization Alternatives for Food Products.
| Type of
 Sterilization  | 
Advantages | Challenges | 
|---|---|---|
| Gamma rays | Penetrate fully to reach surface pathogens and those
 found within the food matrix 14 ; insignificant rise in temperature; high penetrating power; simple process to control 3  | 
|
| Electron beam
 (E-beam)  | 
Sterilization effectiveness comparable to gamma rays 3 | Limited depth; Limited by the penetration
 of electrons (which is proportional to the accelerator) 3  | 
| X-ray | Comparable penetration to gamma rays 3 | Limited use, uncertain cost estimates
 (based on 2008 IAEA review) 3  |
