Uses and synthesis of Sodium Stearoyl Lactylate powder

Sodium Stearoyl Lactylate powder White to light yellow powder, slightly special smell.Sodium Stearoyl Lactylate CAS 25383-99-7 Soluble in hot animal and vegetable oils and organic solvents such as ethanol, acetone, ethyl ether and chloroform, insoluble in water, but can be completely dispersed in water with intense stirring. Sodium Stearoyl Lactylate Raw Materials HLB value is 8.3.

Applications / Functions of Sodium Stearoyl Lactylate powder

Sodium Stearoyl Lactylate powder is used as a W/O food emulsifier, which can be combined with gluten in wheat flour to increase the stability and elasticity of gluten, make the dough fluffy and soft, and not easy to age. It can be used in pastry and bread, the maximum use level is 2.0g/kg.

Production methodprocess of Sodium Stearoyl Lactylate powder

1. One-step method Lactic acid and stearic acid are put into the reactor according to the molar ratio of 2:1, add the concentrated sulfuric acid of 1.5% of the mass of stearic acid, and react at 105℃ for 4h, until no water evaporates; after the reaction is over, lower the temperature, slowly add sodium hydroxide solution to neutralise, and it can be prepared into the emulsion of Sodium Stearoyl Lactylate Raw Materials with solid content of 10%.
2. Two-step method Lactic acid is polymerised under mildly reduced pressure, then stearic acid is added for esterification under the condition of carbon dioxide, and then sodium carbonate is added to neutralise the Sodium Stearoyl Lactylate powder, but it is quite difficult to control the degree of polymerisation of lactic acid in this method, which leads to unstable product quality.
3. Three-step method Firstly, make stearoyl chloride and lactoyl lactic acid respectively, then acylate and neutralise them to form Sodium Stearoyl Lactylate CAS 25383-99-7.
