2013-10-09 by seoer8Glyceryl monostearate, this is actually a play on words and noun practice entirely undesirable . Because , Glycerol monostearate , had not the word , glyceryl stearate may refer to a single bond , the relevant standard does not directly be required for glyceryl monostearate . Basic compounds to the fat called triglycerides , or called triglycerides, are glycerin (glycerol ) was added to three fatty acid molecules to form an ester . Because contains exactly three acid molecules, also called stearin . Hydrogen atom attached to a fatty acid containing a carbon atom chain length . Palmitic acid , stearic acid, oleic acid and linoleic acid are the major fatty acids. We generally say there are two fat , saturated fat and unsaturated fat. The so-called " glyceryl monostearate " , it may be a single acid molecule monounsaturated fatty acids. Because it is unsaturated , it is a liquid at room temperature . If you want to solidify , and transformed into margarine, will be hydrogenated . That is , by destroying the carbon double bond and adding hydrogen atoms to saturate. To complete this process , the need to heat the oil , then add the pressurized hydrogen and nickel catalysts. Thus, the " partially hydrogenated vegetable oil (PHVO)" is produced. PHVO is vegetable shortening and margarine is the main component of such fats .
