Increased levels of policosanol and very long-chain fatty acids in potato pulp fermented with Rhizopus oryzae.
Significant amounts of policosanol and very long-chain fatty acids (VLFAs) ranging in carbon length from 22 to 30 were found in the lipophilic fraction obtained from potato pulp fermented with Rhizopus oryzae. It is believed that these compounds would have originally been present as suberin-related compounds, but not as wax, in the periderm of potato tubers and concentrated into potato pulp during the process of starch production. Moreover, the policosanol and VLFAs extracted from potato pulp with organic solvents were found to have increased after fermentation.
