Description
Technical field
The invention belongs to the Application way field of tree peony shell, be specifically related to a kind of method of comprehensive utilization of tree peony shell.
Background technology
Tree peony (Paeonia suffruticosa) belongs to Paeoniaceae, Paeonia, and being traditional famous flower of China, is also world-renowned flowers, is respectfully called " king in spending ".China is original center and the distribution center of world's tree peony wild species, the cultivation centers of Ye Shi world tree peony garden-variety.
Since reform and opening-up, support that China's tree peony industry obtains and further develops with under the joint efforts of vast tree peony scientific and technical personnel energetically in government.But for a long time, China tree peony only externally carries out exchanging, selling with seedling, small part flower forcing and Fresh Cutting flower, except as except viewing and admiring and being used as medicine with root, the exploitation of other side are less, deep level development is almost blank especially, tree peony purposes is restricted, and ample resources is in idle or wastes.Tree peony shell is exactly wherein important recycling resource.
Tree peony shell is the accessory substance before peony seeds oil expression after shelling, and to set seeds in tree peony year at about 600,000 kilograms, tree peony shell can reach several ten thousand kilograms, and these tree peony shells are taken as discarded object and abandon, and further do not develop it, cause the waste of resource.The domestic research to tree peony shell at present is also blank out.And fact proved, tree peony shell also has potential development and application values.Research finds, the peony oil containing a great deal of in tree peony shell, containing abundant oleic acid, linoleic acid plus linolenic acid.Tree peony shell color is pitch-black shinny, can extract the black pigment of the inside.Containing lignan inside tree peony shell, lignan can be extracted.Tree peony shell can also be utilized in addition to make active carbon.Therefore, be badly in need of redeveloping to these waste resources, excavate its potential value, promote that China's tree peony industry deeply develops.Just under this background, the present invention proposes a kind of method of comprehensive utilization of tree peony shell.
Supercritical fluid refers to that temperature and pressure is in the fluid of more than critical-temperature and critical pressure, both there is the high density of similar liquids, also there is the low viscosity of similar gas, high diffusivity coefficient and good permeability, utilize the physicochemical properties of this uniqueness, the dissolving power of Cucumber is improved greatly, can the abundant extraction of realize target material.And have and extract at low temperatures, there is no dissolvent residual and can the feature such as Selective Separation.Therefore, CO is utilized
2super critical point technology proposes oil processing to tree peony shell, have extraction fully, quality is pure, and the particular advantages such as easy and simple to handle, efficiency is high, no pollution.Peony oil is new resource food, the utilization of tree peony shell or blank.Peony oil industry has risen to national strategy project, and tree peony shell develops research and should be in progress in advance.Therefore for above situation, need to process tree peony shell, realize the comprehensive utilization of tree peony shell, the grease in tree peony shell is extracted, or extract black pigment, the lignan in tree peony shell, also tree peony shell can be made active carbon.Turn waste into wealth, realize its economic worth.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of method of comprehensive utilization of tree peony shell.Adopt supercritical carbon dioxide to the extraction of tree peony shell, from tree peony shell, be extracted the peony oil that purity is higher, or extract black pigment, the lignan in tree peony shell, also tree peony shell can be made active carbon.Tree peony shell is turned waste into wealth, achieves the comprehensive utilization of tree peony shell, also create economic benefit.
A method for the comprehensive utilization of tree peony shell, comprises following step:
