Biobased Materials Production from Biodiesel Residuals of Rapeseed
Table 2
Mean values of relative amount of proteins extracted for comparisons of importance of the use of rapeseed type, glycerol content in the samples, pressing temperature, and pressing time. Mean value for total extraction of proteins from rapeseed flour is set to 100, and the rest of the values are related to this set standard value. Vales are relative means of areas under chromatograms from different extractions or from different parts of the chromatograms as a sum after the three extractions. In the comparisons all samples are compared differing only in one parameter. That means, for example, that both rapeseed cake and flour and all glycerol contents and pressing times are included when the pressing temperature is evaluated.
