Composition of several types of Safflower seed

Abstract

Abstract The residue remaining after commercial extraction of oil from safflower seed has a greater potential as a source of animal feed or human diet supplement than is presently being realized. Safflower seed hull, kernel, and meal were analyzed to provide more information regarding their nutritive possibilities. Commercial and experimental normal hull varieties and experimental thin hull and striped hull varieties were hand separated into hull and kernel fractions and both fractions analyzed for protein, fat, fiber, ash, and amino acids. Samples of partially decorticated commercial meal and undecorticated meal, hulls, and defatted kernel from striped hull seeds were analyzed for protein, fat, fiber, ash, lignin, pentosans, anhydrouronic acid, total and reducing sugars, and amino acids. Cellulose was calculated by difference. A new factor for converting nitrogen to protein for summative analyses of safflower seed was calculated. These analyses indicate that about 15% of the nonfiber, nonash, nonprotein part of the defatted safflower kernel is of unknown composition.
