EFSA considers the use of lecithin in animal feed. The scientific opinion has been published in the EFSA Journal.
The FEEDAP Panel from EFSA re-evaluated lecithin as technological feed additives when used as a feed additive (category: technological; functional group: (c) emulsifiers) for all animal species. This was done after the European Commission received a request from ELMA (Europe Lecithins Manufacturers’ Association) to re-evaluate this particular functional group.
The additives reviewed by EFSA are products that consist predominantly of lecithins derived from rapeseed, sunflower and soybean, with other plant extracts. Three different forms of the additive are produced: regular liquid lecithins, hydrolysed liquid lecithins and de-oiled lecithin powder.
