一种石榴皮色素提取液及其制备方法及用途
摘要：
本发明公开了一种石榴皮色素提取液及其制备方法及用途，包括如下步骤：（1）将石榴皮干燥、粉碎；（2）将粉碎后的石榴皮浸渍到水中，调整pH值，得石榴皮浸渍液；（3）采用超声波-微波协同法对石榴皮浸渍液进行提取，提取结束后所得溶液经后处理，即得石榴皮色素提取液。本发明采用超声-微波协同法提取石榴皮色素，工艺简单，提高了石榴皮色素的提取率，并且色素成分稳定。所提取的石榴皮色素提取液主要成分为多酚，将提取液用于纺织品染色中，具有良好的染色性能。
摘要（英）：

The invention discloses a pomegranate rind pigment extracted liquid, a preparation method and application thereof. The method includes the steps of: (1) drying and crushing pomegranate rind; (2) impregnating the crushed pomegranate rind in water, and adjusting the pH value to obtain pomegranate rind impregnated liquid; and (3) extracting the pomegranate rind impregnated liquid by ultrasonic wave-microwave synergy method, and subjecting the obtained solution to post-treatment at the end of extraction, thus obtaining the pomegranate rind pigment extracted liquid. The invention employs the ultrasonic-microwave synergy method to extract pomegranate rind pigment, the process is simple, the pomegranate rind pigment extraction rate is improved, and the pigment composition is stable. The obtainedpomegranate rind pigment extracted liquid contains polyphenol as the main component, can be applied to textile dyeing, and has good dyeing performance.
