Mustard Seed
There are over 40 different varieties of mustard plants, but three are the most popular for culinary use; black, brown, and white mustard seeds typically go into recipes and making mustard. All three varieties are found in the U.S. as well as other parts of the world.
Mustard is the second most-used spice in the United States, as its usage is only exceeded by the peppercorn. And it’s no wonder since mustard works well with all types of meats, pork, poultry, and seafood. You may be used to standard yellow prepared mustard, but there are other wonderful varieties of seeds and prepared mustards to experiment with.
For size reduction of mustard seeds, there are a few milling equipment options that can be offered depending upon the characteristics (moisture content) of the seeds. One equipment solution is the Mikro Pulverizer providing, for example,  end particle size in the 20 mesh to 30 mesh range. Another equipment solution, for mustard seeds with higher moisture content, is the Alpine CW Contraplex Wide Chamber Impact Mill providing, for example, end particle size in the range of 35 mesh.  Both mill options can be provided with cryogenic milling capabilities to reduce the heat of grinding and reduce the loss of essential oils.
