Abstract:
A method for preparing an expandable shaped half-product comprising the steps of:a) providing a first foodstream of a non-expandable food material to a first injection unit; b) providing a second foodstream of an expandable food material comprising a farinaceous grain to a second injection unit; c) providing a cooled injection mold in communication with the first and the second injection units; and d) forming an expandable shaped half-product by injecting the first foodstream and the second foodstream into the mold through the first injection unit and the second injection unit, respectively, with each foodstream at a foodstream pressure of from about 0 to about 50,000 pounds per square inch, holding the injected foodstreams in the cooled mold until the non-expandable food material and the expandable food material have set so that the shape is retained when the half-product is removed from the mold and wherein the expandable shaped half-product is capable of expanding at least two-fold after heating of the formed expandable shaped half-product.
