Considering the machining efficiency of microwave drying is lower, and the cost is higher, so in mass-production, we recommended adopting steaming drying to process Chrysanthemum morifolium(Ramat) Tzvel.cv.Chuju.2.Studying the steaming drying to process Chrysanthemum morifolium(Ramat)Tzvel.cv.Chuju, with the increase of drying temperature and longer duration of steamed,Luteoloside content gradually increased, 3-3,5-Dicaffeoyl quinic acid content gradually reduced; The content of chlorogenic acid in steamed time 3 min, 4min, and 5min, with the increase of drying temperature, content is gradually increasing, when steamed 6 time min and 8min, the highest content at 80 ℃.Considering that Luteoloside content in Chrysanthemum morifolium(Ramat) Tzvel.cv.Chuju is low, in steamed time of 6min,the drying temperature is 100℃ and steamed time is 8min, the drying temperature is80℃, 90℃ and 90℃ when Luteoloside content is higher, and the difference of several drying methods have no difference, but at 90℃ and 100℃ drying, chlorogenic acidcontent decline dramatically. So choose steamed time is 8min, drying temperature of80 ℃ is the best drying techniques of Chrysanthemum morifolium(Ramat)Tzvel.cv.Chuju.3.Study on Storage Conditions of Chrysanthemum morifolium(Ramat) Tzvel.cv.Chuju,with the reduce of moisture in Chrysanthemum morifolium(Ramat) Tzvel.cv.Chuju,chlorogenic acid, luteoloside and 3-3,5-Dicaffeoyl quinic acid content is gradually increasing, so the Chrysanthemum morifolium(Ramat) Tzvel.cv.Chuju water should be controlled at 11%; From different packing method in Chrysanthemum morifolium(Ramat) Tzvel.cv.Chuju, you can see, by using deoxidizer packaging, the percentage of Chlorogenic acid is low, using ordinary packaging and Using nitrogen filling packaging,the percentage of 3-3,5-Dicaffeoyl quinic acid is low.Therefore, choose the method of vacuum packaging; Chrysanthemum morifolium(Ramat) Tzvel.cv.Chuju in the 4 ℃repository, the color and the variation in content of three kinds of effective components is small, so suggest Chrysanthemum morifolium(Ramat) Tzvel.cv.Chuju save with 4℃repository. So control Chrysanthemum morifolium(Ramat) Tzvel.cv.Chuju the moisture gradient at 11% with the method of vacuum packing in 4℃ refrigerator is the best storage conditions. |
