More Information
Summary:The invention relates to the technical field of plant ingredient extraction, and particularly relates to a technology for ultrasonic-assisted extraction of konjac glucomannan through response surface method optimization. The technology comprises the following steps of (1) soaking konjac into a bactericide and drying and crushing to obtain konjac powder; (2) carrying out degreasing treatment on the konjac powder; (3) removing free revertose from the degreased konjac powder; (4) carrying out ultrasonic-assisted extraction of konjac glucomannan; (5) determining the content and the extraction rate of the konjac glucomannan; and (6) selecting three factors, such as a temperature, a solid-liquid rate and ultrasonic power for response surface experiment design on the basis of a single-factor experiment to obtain the optimal extraction process parameters: the ultrasonic wave power is 43.67w, the temperature is 72.69 DEG C, the solid-liquid rate is 1:120.3g/mL and the prediction extraction rate is 44.38%.
