The impact of roasting on oil and chlorophyll contents, bioactive components, antioxidant activity, phenolic and fatty acid component of rapeseeds
Chlorophyll b quantities of raw (control) and roasted rapeseed samples were specified to be higher than chlorophyll a. Additionally, total phenol, total flavonoid quantities and antioxidant activity (DPPH and FRAP assays) values of roasted powdered and whole rapeseed samples were observed to increase compared to the control. K232 and K270 values of conventional oven roasted, ground and whole rapeseeds were slightly higher than the results in the microwave. The highest K232 value was observed in oil provided from the sample that was powdered and heat treated in conventional oven. The phenolic constituents of ground and whole rapeseeds were partially higher than those of their oils. The dominant fatty acids of the oils extracted from unroasted and roasted rapeseeds were oleic, linoleic, linolenic and palmitic acids in decreasing order. Oleic acid quantities of the oil provided from powdered and whole rapeseeds roasted in microwave and oven were defined as 62.00 and 61.97% to 61.48 and 62.06%, respectively. The main variables of PC1 for rapeseed were dedected as catechin (0.912), coumaric acid (0.840) and ferulic acid (0.733).
Graphical Abstract
In this study, the role of oven and microwave roasting on the oil, chlorophyll, total phenol, flavonoid contents, antioxidant activities (DPPH and FRAP assays), specific absorbance (K232, K270) values, phenolic profile and fatty acid compositions of rapeseed was revealed
