title: [The quality of protein-enriched products from sunflower seeds. 1. The effect of various production processes on the nutritive value of meals and protein isolates].
abstract: Globulin isolates from native sunflower seed and industrial extraction meal obtained by extraction with different electrolyte solutions and subsequent isoelectric precipitation are relatively poor in the essential amino acids lysine, threonine, and methionine as compared to defatted seed meals. On the other hand, albumins separated by means of polyanionic complexing agents (sodium alginate and aluminium potassium sulphate) are relatively rich in these amino acids, and albumin-globulin-co-precipitates have a correspondingly balanced amino-acid composition, being also reflected by nutrition physiological values as BW, NPU, and EAA-index. As compared to seed meals protein isolates are characterized furthermore by a better protein digestibility.
