INDRO PP/PE liquid filter bag in Aseptic Food Processing applications

Aseptic processing is the process by which an aseptic product (typically food or pharmaceutical) is packaged in a container.

It is achieved with a flash-heating process (temperature between 195 and 295 °F (91 to 146 °C)), which retains more nutrients and uses less energy than conventional techniques such as retort or hot-fill canning. Pharmaceutical processing includes use of clean rooms, bacteria retaining filters, dry or steam heat. Aseptic food preservation methods allow processed food to keep for long periods of time without preservatives, as long as they are not opened. The aseptic packages are typically a mix of paper (70%), polyethylene (LDPE) (24%), and aluminum (6%), with a tight polyethylene inside layer. Pharmaceuticals are usually packaged in plastic or glass. Together these materials form a tight seal against microbiological organisms, contaminants, and degradation, eliminating the need for refrigeration.

The first aseptic filling plant for milk was presented in Switzerland in 1961.

Filtration process is important key process of aseptic food process.

Aseptic containers may range in size from a few fluid ounces to a nearly 8-million-US-gallon (30,000 m³) aseptic tank on an ocean-going ship. Aseptic processing makes worldwide export and import of new, economical and safe food products possible. Bag-In-Box technology is commonly used because it provides strong containers that are lightweight and easy to handle prior to being filled. Other common package types are drink boxes and pouches.

Aseptic processing is commonly used for the packaging of milks, fruit juices, liquid whole eggs, gravies, and tomatoes. Fresh tomatoes are aseptically processed and packaged for year-round remanufacture into various food products.
