Based on the basic formula of the bread, wildness shepherd′s purse was added. Taking the amount of shepherd's purse, bread improver, yeast and baking temperature as the factors, the optimal 〖JP2〗technology formula of Shepherd's-purse bread was obtained by single factor test and orthogonal experiment. The results showed that the optimal technology formula of Shepherd′s-purse bread was: with wheat flour as benchmark, the amount of shepherd's purse was 22%, bread improver 1.2%, yeast 1.6%, baking temperature 170℃. The shepherd's-purse bread was soft and tasted good, appeared uniform color with light green color inside and shepherd′s purse fragrance. It greatly enriched the nutrition and varieties of bread, and conformed to the standard of bread by physicochemical and microbiological test.
