Procedure

25 g of powdered palmitic acid (AN 223, titer 60° C., particle size >40μ) and 2.1 g of 96% active magnesium oxide (precipitated, density 70 g/liter, IN 62) are suspended in 500 ml of water at room temperature. This is followed with stirring for 30 minutes at 55° C. and 2 hours at 70° C. The hollow-sphered granulate formed is filtered and dried. The free fatty acid content amounts to 1.3% but if agitation is carried out for 60 minutes only, the granulate still contains 3% of free fatty acid.
