Variety traits
Brassica napus var. napus
The crude protein content in rapeseed seeds ranges from 18–28%, while in meal and cake it reaches 30–45%. This trait has an inverse correlation with oil content, which is taken into account when breeding the crop.
In the reference 50 varieties crop Rapeseed, where this is mentioned in the description.
The protein content in rapeseed seeds is estimated as a percentage of the dry matter weight. For modern varieties, the typical range of crude protein values varies from 21% to 25%. During the industrial processing of seeds for oil, the protein content in by-products—cake and meal—increases significantly.
Rapeseed protein is characterized by a high amino acid content: the lysine level is close to that of soybean, and the methionine and cystine values even exceed it. In breeding, it is necessary to consider the inverse relationship between oil yield and protein accumulation, as well as the influence of husk content and anti-nutritional factors on the final value of the product.
