The invention provides fresh bamboo juice and a preparation method and a quality detection method thereof, relating to the technical field of separation and extraction; the preparation method comprises the following steps: pretreating bamboo chips by using the dicationic acidic ionic liquid solution, heating and dry distilling the pretreated bamboo chips to obtain dry distillation liquid, and condensing and collecting the dry distillation liquid to obtain fresh bamboo juice. The quality detection method comprises the following steps: the method comprises the following steps of character detection, thin-layer chromatography identification, pH value measurement, relative density measurement, total solid content measurement, amino acid content measurement and total fructose, glucose and sucrose content measurement. The bamboo utilization rate is high, the yield of the obtained fresh bamboo juice is high, and is improved by 30 to 50 percent compared with the prior art; the fresh bamboo juice has high content of guaiacol, high content of amino acid and good quality. The preparation method has the advantages of short time consumption, simple procedure, less equipment investment and low production cost, and can be applied to industrial production. The quality detection method of the invention is convenient and fast, and has high accuracy, sensitivity and repeatability. |
