Propylene glycol stearate is milky white solid at room temperature. Not soluble or dispersed in water and also glycerin, soluble in propylene glycol, isopropanol and various other solvents when heated up. The hydrophobic part of its molecular structure is leading, thus providing it water-in-oil emulsifying residential or commercial properties. There is no mesocrystal in water. Monopropyl ester exists in a-crystal form, without polymorphism, but has a-crystal tendency or has a tendency to a-crystal kind, as well as can stabilize x-crystal kind of various other emulsifiers, and has good gas-filling residential or commercial properties. These attributes determine its range of application.
1. Cakes: Propylene glycol stearate integrated with monoglyceride and various other emulsifiers is extensively made use of in the production of pastries, especially cakes. For example, 60% of monopropyl ester, 24% of monoglyceride and 15% of lactoylglyceride are mixed as well as made into powder. The cake is mixed with emulsifier, which can make the cake have a substantial renovation in temperature as well as special water ability. At the same time, the cake has soft cells, penalty and also consistent particle structure and also superb eating top quality. Monopropyl ester can also be combined with sucrose ester or sorbic acid ester to make ointment quick-fat cake oil, which can shorten the mixing time. This emulsifier is especially tolerant to the enhancement method. It has great toughness when whipping, mixing and also baking, as well as is utilized to make muffins and sponge cakes. Some residential monopropyl esters are utilized in the prep work of immediate cake oil. Additionally, it can also be prepared as a powder foaming agent, which has solid emulsifying as well as lathering power, as well as can be used in pastry manufacturing.
Liquid shortening as well as light whipping cream: Monopropyl ester is specifically easy to prepare fluid reducing as a result of its strong lipophilicity. Adding 8-10% monopropyl ester to soybean oil and sunflower oil can obtain uniform and also storage-stable shortening including emulsifiers, which can be made use of to prepare breads and also cakes. 9 ~ 12% monopropyl ester is blended with a percentage of monoglyceride as a frothing cream emulsifier.
In addition, monopropyl ester is made use of in soy item defoamer, instantaneous rice, bread, foamed butter, and so on. Normally speaking, propylene glycol stearate is seldom utilized alone, as well as it is usually used in mix with various other emulsifiers. It is used extra in bread as well as reducing, and also its use in other elements is progressively increasing.
