Abstract
A method is provided for making a helical food product. The method includes the step of extruding one or more plastic food substrates through a nozzle into a hollow shaped part. Relative rotation of the nozzle and the shaping part is caused, thereby forming a product of helical configuration. A fluid barrier agent is applied to the outer surface of the product as it is dispensed from the nozle into the shaping part, which barrier agent is adapted to prevent reannealing of adjacent turns of the helical product.
