Studies On The Preparation Technology Of Natural Wild Chrysanthemum Perfume

Wild chrysanthemum has good medical health and drinking value,its flavor is loved by people because of its refreshing and pleasantaroma, and has become a well-known drinking chrysanthemum.However, wild chrysanthemum–related food, such as chrysanthemumtea, high-temperature sterilization will release bad smell, whichseriously affects the development and promotion of chrysanthemumdeep-processing product. Because the special resources and complexchemical composition of wild chrysanthemum, high-quality synthesisflavor is lacking. And some domestic chrysanthemum perfumes, whichare extracted and separated by traditional methods, cannot avoid aromachanges, but meanwhile most of which have toxic solvents residual andhaven’t enough strength aroma, so they cannot meet the applicationrequirements of food industries.First, in this study, SFE technology was used to extract wildchrysanthemum aroma components. The types of entrainer and itscontent, the extracted pressure, the extracted temperature, the extractedtime and the separated conditions by single factor test were investigated, with the aim to determine the optimum technology which has highextractive rate and prepare high-quality product.Second, molecular distillation was used to remove themacromolecule ingredients so as to separate the essential oil from wildchrysanthemum SFE extraction. The essential oil produced has high andrealistic chrysanthemum aroma.Third, chrysanthemum microencapsulated perfume withstable-quality was prepared by spray drying technology from SFEextractum. The optimum types of wall-material and its content, theprocessing of emulsion and spray drying were optimized.Fourth, ethanol solution–frozen crystallization method was usedto remove the wax from wild chrysanthemum SFE extractum so as topreparation of wild chrysanthemum liquid perfume.Finally, the chemical compositions of chrysanthemum SFE-MDessential oil was identified, some special contribution chemical aromascompositions of it was found, and it was proved that the technology ofsupercritical CO₂extraction was suitable for extracting aroma fromchrysanthemum.All the materials used by this institute are natural rawchrysanthemum flowers, the extraction and separation technologies arepurely physical process, the reagents and drugs used in the processingare food-grade products, the final product has no solvents residual or only food grade reagents, all these indicate that the chrysanthemumperfumes made by these technologies are green and healthy, so they canbe called natural chrysanthemum perfumes. This is in line with modernsocial trends of pursuit natural food additives and has broad potentialmarket prospects.
