Description

Figure 1 Diagrammatic overview of Shaka

Shaka® is one of the processes used to heat packaged foodstuffs. The packaged product is placed into an autoclave that is shaken with a firm, horizontal movement (figure 1). This shaking allows the heat to be distributed more quickly through the product, reducing the heating time with a factor 10 (figure 2).
