Abstract
Virgin rapeseed (Brassica napus) oil is a valuable niche product, if delivered in high quality. In this study, the effects of moist storage of B. napus seeds for one to four days on the seed metabolome and the chemo-sensory properties of the produced oils were determined. The concentrations of several primary metabolites including monosaccharides and amino acids rapidly increased in the seeds, probably indicating the breakdown of storage compounds to support seed germination. Seed concentrations of indole glucosinolates increased with a slight time offset suggesting that amino acids may be used to modify secondary metabolism. The volatile profiles of the oils were pronouncedly influenced by moist seed storage, with the sensory quality of the oils decreasing. This study provides a direct time-resolved link between seed metabolism under moist conditions and the quality of the resulting oils, thereby emphasizing the crucial role of dry seed storage to ensure high oil quality.
