New strategies to reduce solanine and chaconine content in potatoes
Potatoes are a staple food for over one billion people worldwide as well as a primary source of carbohydrates and a vital crop for the South American, African and Eastern/Central Asian economies. They occupy third place (after rice and wheat) on the list of foods the world depends on for food security.
The glyco-alkaloid content in potatoes is potentially toxic and secondary metabolites such as alpha-solanine and alpha-chaconine are considered dangerous for human health.
Researchers from the Federico II University in Naples described new methods to reduce alpha-solanine and alpha-chaconine content in Marabel potatoes. They were incubated at room temperature in the dark for 24 hours and the optimal experimental condition was achieved with a sodium hydroxide (NaOH) solution at pH 12.
In the analysed samples, the reduction of alpha-solianine and alpha-chaconine was 43 and 27% respectively. The process enables the reduction of the total glyco-alkaloid content in relation to harvesting, storage and cleaning modes of Marabel potatoes.
