Following the publication of Jan Velíšek’s work on 3-chloropropane-1,2-diol (3-MCPD) levels in edible oils, the research and development team at Nutriswiss AG has been working to find ways to avoid process contamination during refining.
The focus was on infant formulas as a particularly sensitive product group. Many formulations were found to comprise — and still contain — palm oil, which has a high capacity to form 3-monochloropropanediol (3-MCPD) and glycidol.
Many strategies have been used to develop new processes. Undoubtedly, the best approach is to prevent the formation of contaminants with optimised harvesting and rapid processing at the source.
In this way, levels of <500 µg/kg of 3-MCPD can be achieved. The disadvantage of this strategy is its dependence on selected suppliers.
Irrespective of the quality of the raw materials, Nutriswiss has therefore developed a way to meet the need for particularly low 3-MCPD levels in infant formula.
