The Oil Yield, Mineral Content, and Fatty Acid Compositions of Some Rye (Secale cereale) Grains

Abstract

The oil contents of rye grain seeds ranged from 0.70% (type 25) to 3.92 % (type 1). Palmitic acid contents of oils changed between 10.82% (type 26) and 22.43% (type 10). In addition, while oleic acid contents of oil samples vary between 20.61% (type 17) and 37.86% (type 3), linoleic acid contents of oils changed between 18.91% (type 3) to 54.0% (type 13). Also, linolenic acid contents of oil samples were found between 2.43% (type 1) and 8.34% (type 26). Total saturated fatty acid contents of oil samples changed between 15.57% (typ 26) and 34.38% (type 1). K contents of rye grains were found between 3810.31 mg/kg (type 2) and 6148.28 mg/kg (type 17). While P contents of grains vary between 1806.43 mg/kg (5) and 3710.25 mg/kg (18), Mg contents of samples ranged from 962.87 mg/kg (type 5) to 1602.33 mg/kg (type 12). The highest Ca content was determined in 14 samples (1447.96 mg/kg). The crude protein contents of rye grains ranged from 10.08% (type 1) to 15.25% (type 3). As a result, rye grain is rich in minerals and essential fatty acids for human health.
