栀子花脱水干制工艺研究

On Dehydration Process for Gardenia

以大花栀子为试材,研究了介质及液剂干燥法对栀子花感官品质的影响,测定了花朵失水率和干花品质指标.结果表明:介质干燥法河沙比食盐在失水率、感官品质表现好;液剂干燥法处理i(50%甘油+9%柠檬酸+5%亚硫酸钠+浸泡4h)效果最好;在烘干时间上,液剂干燥法在36h最好,介质干燥在24h最好.

In an experiment with gardenia ,the medium and the liquid desiccant methods were used to study their influence on the dehydration rate and quality indicators of the dried flowers .The results indicated that for the medium desiccant method ,river sand gave better results in dehydration rate and sensory quality of the flowers than table salt ;for the liquid desiccant method ,treatment i （soaking with 50% glycerine ＋9% citric acid ＋5% sodium sulfite for 4h） had the best effect ;and for drying time ,36 and 24 h were the best for the liquid desiccant method and the medium desiccant method ,respectively .
