Changes to the composition of colorants caused by the temperature of drying rapeseed

摘要: Thepigment content in both seeds and oil has been an essential indicator of the quality, particular for cold pressed oil. The chlorophyll depends upon many agents, among which harvesting before full maturity, case one-step technical two-step are most significant ones. quantity designed future processing should not exceed a value 25 mg kg -1 . Where this occurs, remarkable pigments will occur seed cover as well extracted from non - mature seeds. high level negative influence on quality (smell) also stability due to its pro-oxidative action. Another is visual darkening temperature drying presence defective exert colour. Apart rape seeds, caro- tenoid quite considerable amounts. carotenoid very important mainly antioxidant properties (lipid protection) vitamin-forming action (dietary purposes). aim these studies was examination those agents responsible pigment rapeseed.
