New Varieties of Rapeseed as a Source of Proteins

Abstract

The proteins of the new rapeseed varieties Brassica napus, Pmteine aus neuen Raps-SortenDiese Proteinfraktionen lassen sich leicht in hoher Ausbeute isolieren. Sie sind hinsichtlich ihrer ernahrungsphysiologischen Eigensdmften den entspredlenden Rapsinehlen weit iiberlegen. lated in high yields. Their nutritive value is superior to that of the corresponding meals.

Rapeseed protein isolates by countercurrent extraction and isoelectric precipitation

“…Recipient of an Alexander von Humboldt-Fellowship, 1974 Present address: National Research Centre, Dokki, Egypt. relatively high contents of lysine (Leslie and Summers, 1975;El Nockrashy et al, 1975b) which is the first limiting amino acid in cereals and other vegetable proteins; and (d) rapeseed protein concentrates having high nutritional value and satisfactory functional properties are well accepted (Ohlson and Tear, 1974).…”

Determination of amine or amide nitrogen in vegetable oils

“…They demonstrate that olive oil showed no amine nitrogen, while rape and sunflower oils showed a trace of titrable amino nitrogen. However, the crude cottonseed oil showed an appreciable amount of amine nitrogen, probably from phospholipids (4).…”
