NEW RESEARCHES IN THE NUTRIENT COMPOSITIO N OF HEMP SEED LOW GRADED IN CANNABINOL (CANNABIS-SATIVA L)

The breeding of new hemp varities low graded in cannabinol, resulted i n the cancellation of cultivation of hemp prohibited. In this context the exploitation for plant fibres is the main item. In this paper the nutrient aspects of hemp seed were researched. With app. 25 % the oil content is not very high; the oil, however, containes 52 % linoleic ac id and 20 % linolenic acid resp. Additionally 10 % of the linolenic ac id is 2 % gamma-linolenic acid as well. The hemp seed phospholipids ha ve also high amounts of 42 % linoleic acid and 12 % linolenic acid res p., and have more than 45 % phosphatidylcholine additionally. The prot ein of hemp, which amounts to about 26 % of the origin substance, cont aines a low grade of 0,95 % lysine and the value of the total sulphure amino acids methionine and cystine is about 1,03 %.
