  • Patent number: 5238693
    Abstract: A continuous process for producing hard pretzels is disclosed in which the pretzel dough is passed through an initial bath of hot caustic solution to cook the dough and to essentially caramelize its surface; the cooked and caramelized dough is then transported through a spray zone where it is sprayed with atomized hot caustic solution; and the sprayed product is salted with flake-type salt prior to hard baking. The process substantially improves flake-type salt retention at the surface of the pretzel and permits the use of lower concentrations of caustic while surprisingly improving the characteristic taste, texture and appearance of hard pretzels.
