Abstract
The invention relates to a method for extracting chrysanthemum essence oil by a salt leaching method. The method takes chrysanthemum as a raw material, and the essence oil can be obtained through several times of distillation. The raw material chrysanthemum is budding chrysanthemum; the method comprises the following steps: before distillation, using a common salt aqueous solution with mass concentration being 5-20% for immersing the raw material for 3-5 hours, heating the raw material to the temperature of 50-70 DEG C, slaking the material for 5-10 minutes, and distilling the material for 4-10 hours, and collecting the product to obtain the chrysanthemum essence oil fraction. During a whole extraction process, no organic solvent is used, chrysanthemum oil purity is guaranteed, pollution of the chrysanthemum oil can be avoided, and at the same time, the whole production process is clean and pollution-free.
Description
Technical field
The present invention relates to a kind of method of processing of agriculture product, a kind of method that is specifically related to salt and soaks method and extract chrysanthemum essential oils.
Background technology
Chrysanthemum has three large purposes traditionally, and the one, beautify the environment, view and admire for people, the 2nd, concoct chrysanthemum tea, be also one of important consumer channel of chrysanthemum as a kind of chrysanthemum tea of health beverages, the 3rd, be applied to Chinese medicine.
Oil of Flos Chrysanthemi has the natural aromatic of chrysanthemum, is used for the production of high-grade cigarette and essence. The preparation of oil of Flos Chrysanthemi mostly is organic solvent extraction, and the organic solvent of infiltrating in extraction process is difficult to remove clean, has affected to a certain extent the quality of oil of Flos Chrysanthemi.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provide a kind of new, method is reasonable in design, easy to operate, the salt that can effectively make finished product soaks method and extracts the method for chrysanthemum essential oils.
Technical problem to be solved by this invention is to realize by following technical scheme. The present invention is a kind of method that salt soaks method and extract chrysanthemum essential oils, is characterized in: the method is raw materials used is chrysanthemum, mainly forms and obtains essential oils through the distillation of several times; Described raw material chrysanthemum is the chrysanthemum that a bud just ready to burst; The sodium-chloride water solution that is first 5-20% by mass concentration before distillation soaks 3-5 hour, is then heated to 50-70 DEG C of slaking 5-10 minute, and the redistillation time is 4-10 hour, collects and obtains chrysanthemum essential oils fraction.
Salt of the present invention soaks the method for method extraction chrysanthemum essential oils, further: the sodium chloride solution that is first 10% by mass concentration before distillation soaks 4 hours.
Salt of the present invention soaks the method for method extraction chrysanthemum essential oils, further: be heated to 60 DEG C of slakings 7 minutes.
Salt of the present invention soaks the method for method extraction chrysanthemum essential oils, further: distillation time is 6 hours.
Salt of the present invention soaks the method for method extraction chrysanthemum essential oils, further: the chrysanthemum picking is put into retort, the upper wire netting of retort bottom pad, chrysanthemum is deposited on wire netting; The sodium chloride solution of preparation 10%, add in retort, by retort good seal, be heated to start to distill after 50-70 DEG C of slaking 5-10 minute, and making water in retort keep fluidized state, the cut of collecting in still-process leaves standstill, and allows distillate natural layering, the oil reservoir at every turn separating is put together, water layer is again put in retort and continued to participate in distilling; The oil reservoir of each collection is merged.
Compared with prior art, the present invention does not use any organic solvent in whole leaching process, has not only ensured the purity of oil of Flos Chrysanthemi, and oil of Flos Chrysanthemi is not polluted, and meanwhile, whole production process is also cleanliness without any pollution.
Detailed description of the invention
Below further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
Embodiment 1, a kind of salt soaks method and extracts the method for chrysanthemum essential oils: the method is raw materials used is chrysanthemum, mainly forms and obtains essential oils through the distillation of several times; Described raw material chrysanthemum is the chrysanthemum that a bud just ready to burst; The sodium-chloride water solution that is first 5-20% by mass concentration before distillation soaks 3-5 hour, is then heated to 50-70 DEG C of slaking 5-10 minute, and the redistillation time is 4-10 hour, collects and obtains chrysanthemum essential oils fraction.
Embodiment 2, the method for soaking of the salt described in embodiment 1 is extracted in the method for chrysanthemum essential oils: the sodium chloride solution that is first 10% with mass concentration before distillation immersion 4 hours.
Embodiment 3, the salt described in embodiment 1 or 2 soaks method and extracts in the method for chrysanthemum essential oils: be heated to 60 DEG C of slakings 7 minutes.
Embodiment 4, the salt described in embodiment 1 or 2 or 3 soaks method and extracts in the method for chrysanthemum essential oils: distillation time is 6 hours.
Embodiment 5, the salt of embodiment 1-4 described in any one method of soaking is extracted in the method for chrysanthemum essential oils: the chrysanthemum picking is put into retort, the upper wire netting of retort bottom pad, chrysanthemum is deposited on wire netting; The sodium chloride solution of preparation 10%, add in retort, by retort good seal, be heated to start to distill after 50-70 DEG C of slaking 5-10 minute, and making water in retort keep fluidized state, the cut of collecting in still-process leaves standstill, and allows distillate natural layering, the oil reservoir at every turn separating is put together, water layer is again put in retort and continued to participate in distilling; The oil reservoir of each collection is merged.
