Effective sterilization methods play a critical role in the aseptic manufacturing process, requiring food and beverage manufacturers use only proven, highly effective processes. Hydrogen peroxide and paracetic acid have shown themselves to be effective processes, however they have limitations. Both of these chemical methods are limited by a narrow process window, have limitations on speed and heat, produce residuals, consume utilities, and create a large footprint. High capital costs, combined with the high maintenance, spare parts, and operating costs, make sterilization a large component of an aseptic bottler's expenses.
Decades of research and commercial use have proven that electron beam technology is a safe and effective method for sterilization. However, conventional electron beams systems are large, expensive and complex to maintain, making them impractical for use in many packaging applications. As such, a more cost-effective, compact approach to electron beams is required.
