How is puffed wheat puffed?

[Linux]

We have puffed wheat for breakfast sometimes, when I asked wondering how manufacturers puff their wheat?

My DD says the wheat grains are first heated, then pressurised with compressed air - then the air is suddenly released, causing said grains to puff up.

Is this true?

Quaker Oats says it's "shot from guns", and that's even before the Internet, so it must be true!

From this article on Wikipedia.

High pressure puffed grain is created by placing whole grains under high pressure with steam. When the containment vessel's seal is suddenly broken, the entrained steam then flashes and bloats the endosperm of the kernel, increasing its volume to many times its original size.

Gosh, .40 - my DD wasn't far wrong being ever the scientist.

Thanks very much, and to you, MSC.

They're under contract with Kellogg's, making cornflakes.
