Procedure: Sprinkle B into A under vortex agitation. After hydration, add C to batch and heat it to 75-80°C under agitation. Separately combine D and heat to 75-80°C under agitation until homogenized. Slowly introduce E into D under dispersing. After introduced, continue to disperse it around 20 minutes. Transfer DE into batch and emulsify around 2 min. Cool down with slow mixing speed. Introduce F one by one until the temperature is below 55°C. Agitate until ambient temperature.
