Compositional data on sunflower seed

Abstract

Abstract Comparative data are provided on the composition of achenes from sunflower varieties Armavirec, Peredovik, VNIIMK 8931, Smena, Krasnodarets, Arrowhead and Mingren. Handseparated achene components were analyzed. Kernel oil from seed raised in northern United States or southern Canada typically contains about 70% of linoleic acid. In addition to other common acids, traces of C 17 , C 20 , C 22 , C 24 acids and linolenic acid are present. The amino acid composition of sunflower kernel protein suggests that the meal may be a valuable ingredient of high‐quality feed or food materials. The hull is primarily cellulose, lignin and pentosans; hull lipid and protein differ in composition from the corresponding kernel constituents.
