Description
Summary:The quality and safety of rapeseed are greatly affected by glucosinolate and erucic acid. To determine the quality of a new variety, 'Kangyu' was cultivated at 3 different regions and analyzed to evaluate oil quality and glucosinolates contents. The new cultivar accumulated 38-43%(w/w) of oil and $5-14{\mu}mol/g$ of glucosinolates, whereas the local race contained 43% and $52{\mu}mol/g$, respectively. The total glucosinolates in 'Sunmang' was above the permissible limit. All 'Kangyu' samples had safe fatty acid compositions but the local race contained 43% of erucic acid (C22:1) that is far from the International Standard. The contents of oleic (C18:1), linoleic (C18:2), and linolenic acid (C18:3) in 'Kangyu' were 61-65, 21-23, and 9-10%, respectively. Consequently, 'Kangyu' was good oil source in Korea in terms of erucic acid (C22:1) and total glucosinolates for human health.
