Aseptic processing and packaging is the filling of commercially-sterilized products into pre-sterilized containers.
1. After you process, commercially sterilize, and cool your product, it’s ready to deliver to the filler.
2. We pre-sterilize incoming flexible packaging, so when it arrives at your location, it’s safe and ready for aseptic filling.
3. The external surfaces of the cap and spout are then re-sterilized with our patented Vapor Sterilant Technology™ (VST).
4. Your flexible package then enters a pre-sterilized, enclosed atmosphere that is free of microorganisms, where the cap is removed to begin the filling process. Filling takes place through the spout. The cap is then hermetically sealed onto the spout, creating a contained sterile package for your aseptic product.
Retort takes place when you fill non-sterile product in hermetically-sealed, non-sterile packaging. The packaging is loaded into a retort pressure vessel and subjected to pressurized steam. The product is also exposed to high temperatures for a much longer period than in hot-filling. The additional time can significantly deteriorate the overall quality and nutritional content of the product.
Aseptic is a desirable alternative to hot-fill or retort processing because it doesn’t expose products to extended periods of high thermal temperatures, which can lead to vitamin, color, taste, and texture degradation. The aseptic process ultimately ensures a better quality product that can still maintain shelf-stable distribution.
