You are given a material that is 20% fat, 8% protein, 5% monosaccharide, 1% ash and the rest water. Based on your knowledge of separation technologies outline an approach you could use to fractionate the first four of these items from the others. Water can be part of the separated streams, but the other three items shouldn’t be present i.e. fat and water but no protein, sugar or minerals should be present. This is to be a commercial scale approach...
