Abstract:

With Fortunella japonica skin powder as raw material, ethanol-extracted cellulose solution Fortunella japonica flavonoids from the study. Single factor tested to determine the impact of the extraction rate of the main process parameters, namely ethanol concentration, water temperature, solid to liquid ratio, enzyme amount, and extraction time, and on this basis to L16(45) orthogonal test. Optimum conditions for the optimum temperature was 50℃, 70% ethanol concentration, solid to liquid ratio of 1:35, enzyme concentration 0.5%, extraction time 100 min, can achieve the best extraction effect.
