More Information

Add phase A to the main vessel. Dissolve phase B with continued mixing. Add phase C, stirring until fully incorporated. Start heating to 85°C and add premix of phase D. To a secondary vessel, add phase E. Start mixing and add phase F. Heat to 85°C, and then add phase phase G ingredients, in order. With both phases at 85°C, slowly add the oil phase (EFG) to the water phase (ABCD) with prop mixing. Start homogenizing and cooling. When the batch reaches 55°C, start sweep mixing and continue cooling. At 50°C or lower, add phase H with mixing. When batch is smooth, add I with mixing and replace any water lost to evaporation. Mix until again smooth and at desired filling temperature. Stop cooling and mixing, perform final quality assurance checks and package product.
