A reader asks:
Some flavorings say they have “glycerine” in them. Is glycerine from animals or vegetables?
Jeanne Yacoubou, MS, VRG Research Director responds:
Glycerine can be animal- or plant-derived. It is also possible to produce glycerine from petrochemicals.
If plant-derived, glycerine is probably from soybeans. Animal tallow is a common animal source. I have received statements from several major manufacturers of glycerine. My general impression at this point (early 2010) is that it is typically derived from plant materials when used in food but one cannot always be sure, especially in cosmetics and bath and body products. It is best to ask the product’s manufacturer when in doubt.
