山茶花干燥护形技术研究

以山茶Camellia japonica鲜花为试材,以感官分值和含水率为指标,研究不同化学溶液和包埋材料处理对山茶花的干燥护形效果,寻找最佳护形方法。结果表明：不同化学溶液处理对山茶干花护形效果不同,其护形效果的优劣顺序分别为：无水乙醇中浸泡3.0h后用体积分数为50%二甲苯浸泡2d〉体积分数为30%的甘油中浸泡4.0h〉250g·L-1的蔗糖溶液浸泡4.5h〉无水乙醇中浸泡3.0h后用体积分数为50%丙二醇浸泡2d;不同包埋材料中以1/2硅胶＋1/2氯化钠的包埋效果最好。

Drying and shape maintaining of Camellia japonica flower

Taking fresh flowers of Camellia japonica as a testing material, and sense score and water content as indexes, the effects of different chemical solutions and investment materials on drying and shape maintaining of Camellia japonica flowers were studied, in order to find out the best way to maintain its shape. The results indicated that treatment with different solutions had different effects on the shape maintenance of the flower. The order from the best to the worst maintenance effect was ： dipping in the 50% xylene for 2 days after disposing in absolute alcohol for 3.0 hours 〉 dipping in the solution of 30% glycerin for 4.0 hours〉 dipping in the 25% sucrose solution for 4.5 hours〉 dipping in the 50% propylene glycol for 2 days after disposing in absolute alcohol for 3.0 hours. The best shape maintenance effect of investment materials were 1/2 silica gel plus 1/2 sodium chloride.
