Abstract

The invention discloses a process for extracting osmanthus fragrans oil by using a supercritical carbon dioxide fluid and application of the osmanthus fragrans oil in lip balm and hand cream. The extraction process comprises the following steps: freeze-drying fresh sweet osmanthus flowers in a freeze dryer to obtain dried sweet osmanthus flowers, collecting sweet osmanthus flower cell sap and storing the sweet osmanthus flower cell sap in a refrigerator; crushing and sieving the dried sweet osmanthus flowers to obtain dried sweet osmanthus flowers with uniform particles, and hermetically storing the dried sweet osmanthus flowers by using a dry and clean ziplock bag; pouring grape seed oil into the dried sweet osmanthus flowers, conducting uniform stirring, and carrying out ultrasonic treatment; loading the sweet osmanthus flowers into an extraction kettle for extraction to obtain grape seed oil containing an osmanthus fragrans extract; subjecting the grape seed oil containing the osmanthus fragrans extract to freezing and standing, and then performing suction filtration until no floccule appears after a filtrate is centrifuged so as to obtain the osmanthus fragrans oil. According to the method, the extraction rate of essential oil in plants, especially in the flowers of the plants, in virtue of supercritical fluid extraction is effectively improved, more attention is paid to utilization of byproducts in the extraction process, the commercial additional value of osmanthus fragrans is improved, and the commercialization of osmanthus fragrans extract-containing products is practically promoted.

Description

technical field [0001] The invention relates to a preparation process of osmanthus oil, in particular to an extraction process of supercritical carbon dioxide fluid extraction of osmanthus oil and its application in lip balm and hand cream, belonging to the technical field of daily chemical product processing. Background technique [0002] Osmanthus fragrans (Osmanthus fragrans) is a plant of the Oleaceae family, native to my country. It is one of the top ten traditional famous flowers in my country. It is a variety of fragrant flowers with great ornamental and practical value. Arbor economic tree species, mainly distributed in Guangxi, Jiangsu, Zhejiang, Hunan, Hubei and other places. Osmanthus fragrans essential oil, hydrosol, and extract (clean oil) all have the characteristic aroma and efficacy of osmanthus to varying degrees, but traditional extraction methods, such as steam distillation, organic solvent extraction, and supercritical fluid extraction, all have extremely ...
