Extraction of spinach pigments by improved method and the preparation for sodium copper chlorophyllin

Objective： To study on the extraction process and its storage conditions of spinach pigments. Methods：Spinach pigment was obtained by organic solvent. The extractive rate at different temperatures and times was testified to determine optimum extractive conditions. At the same time the technology of spinach extraction was studied by using yield as an index by ultrasonic - assisted technique. The optimum extraction condition of ultrasonic - assisted technique and the preparation of copper sodium salt from chlorophyll were determined by orthogonal experiment. Results： Temperature was 50℃ ;The amount of the solvent （ per 1.0 g paprika red pigment） was 5 ml, extraction time was 60 minutes, ultrasonic - assisted technique power was 200 W and yield was 52.6%. Conclusion ： Compared with traditional extract method, ultrasonic - assisted technique can improve the extraction yield.
