Rapid detection method and device for soft white sugar

The invention discloses a rapid detection method and device for soft white sugar. The method comprises the following steps: acquiring various parameter indexes of different soft white sugar samples, wherein the parameter indexes comprise reference values of the soft white sugar samples; scanning the near-infrared original spectrum of each sample by adopting a near-infrared spectrometer, and scanning the reference value of the known soft white sugar sample to obtain near-infrared original spectrum data of the soft white sugar; inputting the reference value into the near-infrared original spectrum data, and exporting a near-infrared original spectrum chart; the near-infrared original spectrogram is preprocessed; establishing a mathematical model of the soft sugar sample according to the pretreatment result, wherein the mathematical model of the soft sugar sample is used for predicting the color value, reducing sugar and moisture of an unknown soft sugar sample; scanning new soft white sugar, predicting an unkno
