Chorleywood bread process last requirement means that it is difficult to reproduce CBP in a small-scale kitchen. The CBP is only a method of producing quick-ripened bread dough. Large-scale bread-making with automated processes pre-dates the CBP by at least a century. Flour, water, yeast, salt, fat, and, where used, minor ingredients common to many bread-making techniques such as Vitamin C, emulsifiers and enzymes are mechanically mixed for about three minutes. The high-shear mixing generates high temperatures in the dough, which is cooled in some advanced mixers using a cooling jacket. Chilled water or ice may also be used to counteract the temperature rise
Bread contains three water-soluble protein groups (albumin, globulin, and proteoses) and two water-insoluble protein groups (glutenin and gliadin). When flour is mixed with water, the water-soluble proteins dissolve, leaving the glutenin and gliadin to form the structure of the resulting bread. When relatively dry dough is worked by kneading, or wet dough is allowed to rise for a long time (see no-knead bread), the glutenin forms strands of long, thin, chainlike molecules, while the shorter gliadin forms bridges between the strands of glutenin. The resulting networks of strands produced by these two proteins are known as gluten. Gluten development improves if
