杜鹃花液剂干燥技术研究

目的]研究化学液剂对杜鹃花（Rhododendron obtusum）干燥的效果。方法]测定6种液剂处理后杜鹃花的失水率、感官分值。结果]甘油替代花中水分具有维持植物材料刚性效果,又能起到保色的作用;亚硫酸可抑制色素氧化,防止花朵褐变,提高了花材的观赏价值。2%甘油＋6%柠檬酸＋2%亚硫酸钠混合液为最佳处理配方,48 h为最佳浸泡时间。结论]该研究可为杜鹃花干花制作提供参考。

Study on Drying Technology of R. obtusum Liquid

Objective] The aim was to study the drying effect of chemical liquid on R.obtusum.Method] The water loss rate and sensory scores of R.obtusum treated by six liquids were detected.Result] Glycerin could not only maintain the rigidity of flower,but also keep the color from fading.Sulfite could slow down the oxidation of pigment and stop the flower from browning,thus improving the ornamental values of flowers.The best formula was the mixture of 2% glycerin,6% citric acid,2% sodium sulfite and 90% water,and the ideal soaking time was 48 h.Conclusion] The study can provide reference for preparing dry flower of R.obtusum.
