Aseptic processing was derived from Olin Ball's heat-cool-fill (HCF) machine that was developed in 1927. [5] While HCF was successful in improving the sensory quality of the processed chocolate milk as compared to canned product, the use of the equipment was hindered by its cost, maintenance, and inflexibility to process various container sizes, rendering the machine a failure.
Both are devices that provide a physical and aerodynamic (air overpressure) barrier between the external clean room environment and a work process. The isolator design is the more dependable of the two barrier design choices, as it prevents contamination hazards by achieving a more comprehensive separation of the processing environment from the ...
In microbiology, sterility assurance level (SAL) is the probability that a single unit that has been subjected to sterilization nevertheless remains nonsterile.. It is never possible to prove that all organisms have been destroyed, as the likelihood of survival of an individual microorganism is never zero.

The BFS process functions similarly to conventional extrusion blow molding, and takes place within a BFS machine. [6] First, a plastic polymer resin is heated to >160 °C and compressed to 35 MPa, [11] [15] allowing it to be extruded in tubular form, [1] and be taken over by an open two-part [16] mold to form the container.
It allows the sterile packaging of a wide variety of food and drink handled by aseptic processing and is used as an alternative to traditional industrial canning methods. Retort pouches are used in baby and toddler food , camping food , field rations , fish products , [ 1 ] instant noodles , space food [ 2 ] sports nutrition and brands such as ...
