White Paper Describes How New Retorts Are Producing Aseptic Quality Food at a Fraction of the Cost
31 Jan 2012
A white paper from Allpax, powered by Pro Mach, looks at how the Shaka(R) retort process blurs the lines between UHT/aseptic packaging and retort sterilization, making it possible for a processor to produce UHT quality food through a batch retort process that has a significantly lower capital and labor cost; faster time to market, including validation; and greater flexibility than UHT processing.

The white paper details the results of a five year research and development effort to commercialize the Shaka process and includes charts and a Shaka retort production video. Shaka retorts agitate packaging using a six-inch double-stroke reciprocating movement at speeds greater than 100 double strokes per minute. The intense horizontal back and forth movement is equivalent to as high as 2 gs of force and this creates a uniform internal heat map within the package.
At a Shaka agitation of 180 reciprocating double strokes per minute, cook time for 400 gm cans of vegetable soup reduce from 50 minutes to 5 - a 90 percent reduction. The production unit is a single production size basket with a capacity of 1,500 lbs. of product. Thus with 3-6 batches per hour, this small footprint Shaka(R) retort can process 4,500-9,000 lbs. of product per hour. Research reveals that the quality of foods produced by the Shaka process is equivalent to that produced by aseptic packaging. Taste, texture, color, nutrient retention, and cook values over a range of products showed minimal differences between products aseptically processed and those Shaka processed.
The white paper, Shaka Retorts Shake Up the Shelf-Stable Food Paradigm, is being offered as a free download by Allpax.
