The present invention discloses an
anthocyanin film coated gel soft sweet preparation
process optimization method, and relates to the technical field of soft sweet production and
processing, the method comprises the processes of gel melting,
sugar melting, blending, molding,
coating pretreatment and
coating, and a low temperature ultrasonic mixing technology is introduced in all the mixing processes in the previous steps, uniform dispersion of components is effectively promoted through vibration of the ultrasonic equipment, meanwhile, the working intensity of the ultrasonic equipment is automatically adjusted through a
PID control algorithm according to real-time temperature feedback, and it is ensured that the temperature in the mixing process is always maintained in a
target range. The temperature deviation is monitored in real time through a PID control method, the ultrasonic power is adjusted, the temperature change can be accurately controlled in the whole preparation process, heat-sensitive components such as
anthocyanin are prevented from being inactivated due to overheating, and the effectiveness and stability of the heat-sensitive components are ensured.
