Van den Bergh Foods , a division of Unilever subsidiary Conopco , has been awarded a new patent for 'edible fat spread.' The background to the patent is that recent publications have stated that trans unsaturated fatty acid residues have an effect on blood cholesterol levels resembling that of saturated fatty acids (SAFA). These findings have created a consumer demand for products in which the content of trans fatty acid residues is at least considerably reduced, but preferably zero.
