(1) Rye grains harvested in Shimane prefecture were milled and seven flour fractions of various milling yields (0-30%, 30-40%, 40-50%, 50-60%, 60-70%, 70-80%, 80-100%) were sampled.
Contents of general components of these flour fractions were determined and the contents of general components of the flours of various yields, 30, 40, 50, 60, 70, 80 and 100%, were calculated.
(2) The more milling yields increased, the lower the "quality" of the flours became. (N-free extracts became lower and the other general components became higher. Fig.1)
(3) Flours of the yields up to 50 or 60% were white and fine. Their crude ashes were 0.5 or 0.6%.
