摘　　要：以红色非洲菊为实验材料,用不同种类及浓度的保色剂对非洲菊进行不同时间的保色处理,通过自然干燥和氯化钠包埋2种方法对其进行干燥,筛选出适宜的干制保色方法。结果表明:2种干燥方法下均为5%蔗糖+10%酒石酸溶液处理11 h后感官分值最高;软化效果为10%氯化锡溶液>5%蔗糖+10%酒石酸溶液>10%柠檬酸溶液;2种干燥方法下均为5%蔗糖+10%酒石酸溶液处理11 h,花瓣与鲜花的颜色最为接近;自然干燥下5%蔗糖+10%酒石酸溶液处理11 h的色差最小,10%氯化锡溶液处理11 h的色差最大;氯化钠包埋干燥下5%蔗糖+10%酒石酸溶液处理11 h的色差最小,10%柠檬酸溶液处理14 h的色差最大。对非洲菊保色效果最好的方法为5%蔗糖+10%酒石酸溶液浸泡处理11 h,包埋干燥能达到良好的防皱效果。Using red Gerbera jamesonii as experimental material,different kinds and concentrations of color retention agents were used to treat Gerbera jamesonii for color retention at different times,and two methods of natural drying and sodium chloride embedding were used to dry Gerbera jamesonii,so as to select the appropriate dry color retention method.Results:The sensory score of 5%sucrose+10%tartaric acid solution in the two drying methods was the highest after 11 h treatment.The softening degree was 10%tin chloride solution>5%sucrose+10%tartaric acid solution>10%citric acid solution.The color of petals of Gerbera jamesonii treated with 5%sucrose+10%tartaric acid solution for 11 h under two drying methods was the closest to that of fresh flowers.Under natural drying,the color difference of 5%sucrose+10%tartaric acid solution for 11 h was the smallest,and that of 10%tin chloride solution for 11 h was the largest.Under the condition of sodium chloride embedding and drying,the color difference of 5%sucrose+10%tartaric acid solution for 11 h was the smallest,and that of 10%citric acid solution for 14 h was the largest.The results showed that the best formula for color retention of Gerbera jamesonii was soaking in 5%sucrose+10%tartaric acid solution for 11 h,and embedding drying can achieve good anti-wrinkle effect.
