| Abstract: | Objective] The study aimed to explore the optimum technology and stability of pigment from the ginger in west Guangxi by the ultrasonic method.Method] With the ginger as the material,the effects of different solid-liquid ratio,extraction temperature,ultrasonic power and extraction time on the extraction effect of pigment from the ginger were studied by the single factor test,the optimum technology conditions for extracting the pigment from the ginger were confirmed and the influences of pH value,temperature,metal ions,common food additives,antioxidants and reducing agent and the sun light on the pigment from the ginger were investigated through the stability experiment.Result] The optimum technology conditions for extracting the pigment from the ginger were as follows: the solid-liquid ratio of 1∶ 30,extraction temperature of 65 ℃,ultrasonic power of 140 W and extraction time of 40 min.The pigment from the ginger was stable in acidic condition and had the good heat resistance,more poor resistance to the light and more strong resistance to the oxidation reducing.Sodium benzoate and citric acid had a greater influence on the pigment from gender.Among the metal ions,Ni2+,Fe3+ and Cu2+ had a certain influence on the stability of pigment,with influence of Fe3+ being most.Conclusion] The study laid the theoretical basis for the development and utilization of the pigment from gender. |
