We have previously reported that canola sprouts, on an average, contained 27.3% oil, 25.1% protein, and 10.8% crude fiber on a dry weight basis (Bhardwaj and Hamama, 2007) and 0.98, 1.23, 427, 0.57, 8.8, 430, 312, 4.54, 15, 607, 573, and 4.89 mg/100 g of aluminum, boron, calcium, copper, iron, potassium, magnesium, manganese, sodium, phosphorus, sulfur, and zinc, respectively (Bhardwaj and Hamama, 2009). In addition, contents of various minerals in canola sprouts were observed to be superior to those in sprouts of alfalfa, brussels sprout, mungbean, and radish based on literature values for these crops. Given that there is a lack of fatty acid profile of canola sprouts in the literature, we are now reporting the contents of various fatty acids in these sprouts.
The term “Canola” is a registered trademark of Canadian Canola Association and refers to cultivars of oilseed rapeseed (Brassica napus L. and B. rapa L.) that produce seed oils with less than 2% erucic acid (C22:1 fatty acid) and meals with less than 30 μmol of aliphatic glucosinolates per gram (Raymer, 2001). Current canola cultivars are essentially free of erucic acid and glucosinolatres. Demand for canola oil is increasing for human consumption as a result of its lowest content of saturated fatty acids (5% to 8%) and moderate content of polyunsaturated fatty acids (PUFA).
The objectives of this study were to ascertain affects of cultivars and growing locations on contents of various fatty acids in canola sprouts. In addition, we also evaluated the ratio of omega-6 to omega-3 fatty acids [linoleic (C18:2) versus linolenic (C18:3) fatty acids] in canola sprouts resulting from considerable importance of this ratio in human nutrition.
