 Aseptic processing was derived from Olin Ball's heat-cool-fill (HCF) machine that was developed in 1927.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.In the 1940s, the Avoset process was developed by George Grindrod.
