Milling quality of hulled wheat bulgur with stone mill

Abstract

In recent years, hulled wheat species have increased in importance because of their advantageous features as underutilized crops which have provided additional income to farmers and also contributed to agricultural diversification. Einkorn and emmer as two hulled wheat species have been used in this study. The milling quality of these hulled wheats was determined on fixed top stone and fixed bottom stone (FBS) mills at 1.75- and 2.5-mm stone gap levels. The effects of parameters such as stone mill type, stone gap and milling quality of hulled wheat species have been studied. The obtained products have been classified as coarse (over 2 mm), medium (under 2 mm-over 1 mm), fine (under 1 mm) and husky. It reveals that FBS mill has ground in little particles and more unsteadily. This study also indicates that the grinding of emmer has brought along smaller particles due to its spindly structure and 1.75-mm stone gap has been thought more acceptable because of the less husky product. © 2009 Wiley Periodicals, Inc.
