Liberty - Glyceryl Mono Stearate (G.M.S.)
G.M.S. Is a well known emulsifying agent which is extensively used by the modern food stuffs industries. It contains both water & oil soluble groups in one molecule. This characteristic structure enables is to be a very effective emulsifier. Another important advantage to G.M.S. is high nutritive value. It is non toxic & therefore very suitable for use in food formulation. It belongs to the class of non inoic emulsifiers. G.M.S. is manufactured by Liberty Chemicals in different grades Viz. SE & NSE.
The Method of incorporation is to make a stock mixture of G.M.S. SE in water in the following manner:
- Heat 6 liters of water to boiling point.
- Add 1 kg. Of G.M.S. SE with mechanical agitation.
- Stirr the solution till the powder dissolve completely.
- Allow the solution to cool.
- The thick pest which is formed is ready for use.
Tests have shown that where a baker is adding fat in lump form to the dough, the amount of fat used can be reduced by more than 50%. Thus the use of G.M.S. SE itself gives loaf a much improved quality at a reduced cost to the baker.
G.M.S SE improve all types of cakes. The optimum concentration to be used will depend on the receipt. But in most cases about 3-4% on the weight of flour is adequate. In cake manufacture 6 liters of water is heated to boiling, heating is discontinued, then 1 kg. G.M.S SE Flakes added & mixed in with a hand paddle or mechanical agitator for several minutes. The mixture is allowed to cool to room temperature & is than ready for use. It is suggested that since no preservative is added, only sufficient should be made up at a time. The best results are obtained when added to the milk, or eggs & mixed on the fast speed.
G.M.S. SE give cakes of good volume. They are more tender & keep their freshness longer.
