Abstract
The invention discloses a kind of extracting methods of Jiang Miao essential oil, comprising the following steps: takes the ginger Jiang Miao newly harvested, in the sun naturally dry to constant weight；Jiang Miao after drying is ground into Jiang Miao powder, crosses 70 meshes, sodium chloride solution is added, stirring is placed in distilling apparatus, and distillation obtains distillate；Petroleum ether is added in distillate, is extracted, extraction time is 10min~15min, obtains extract liquor；The petroleum ether liquid for extract liquor being extracted again containing essential oil；By the petroleum ether liquid heating containing essential oil, obtained phegma is extraction of essential oil liquid.The invention has the advantages that the aerial stem of plant part Jiang Miao using ginger extracts Jiang Miao derived essential oil; not only meet the growing demand of consumer; essential oil price is reduced simultaneously; improve social benefit and ecological benefits; it solves because putting aside as useless Jiang Miao in Tanaka; the problem of causing the significant wastage of environmental pollution and resource protects environment.
Description
Technical field
The present invention relates to a kind of extracting methods of Jiang Miao essential oil.
Background technique
Ginger is widely known flavouring in China, or a kind of important Chinese medicine, and ginger contains pungent and fragrant
Ingredient, piquancy component be a kind of armaticity stearopten in " zingerone ", wherein predominantly ginger oil terpene, phellandium, camphor terpene,
Gingerol, folium eucalypti olein, starch, mucus etc..
Ginger be integrate flavouring, processed food raw material, medicinal vegetables multipurpose vegetables, either city at home
, or in international market, ginger has wide market.In recent years, Japan, country in Southeast Asia's economic liftoff, gradually ignore
The production of the more ginger of cultivation trouble, recruitment, increases sharply to the demand of China ginger, in addition the cultivation history that China is long
With unique processing technology, ginger cultivation becomes one of the important means of farmer richness.It is therewith ginger with the problem come
After harvest, Jiang Miao is put aside as useless the significant wastage that environmental pollution and resource are caused in Tanaka by most of farmer.
Summary of the invention
Goal of the invention: in view of the above-mentioned problems, the object of the present invention is to provide a kind of extracting method of Jiang Miao essential oil, ginger is utilized
Seedling extracts active constituent essential oil, provides an important channel to solve environmental pollution and the developing market Jiang Miao, improves Jiang Miao's
Economic value.
A kind of technical solution: extracting method of Jiang Miao essential oil, comprising the following steps:
Step 1: the ginger Jiang Miao newly harvested is taken, in the sun naturally dry to constant weight；
Step 2: the Jiang Miao after drying is ground into Jiang Miao powder, crosses 70 meshes, sodium chloride solution is added, stirring is placed on
In distilling apparatus, distillation obtains distillate；
Step 3: being added petroleum ether in distillate, is extracted, and extraction time is 10min~15min, obtains extract liquor；
Step 4: the petroleum ether liquid for extract liquor being extracted again containing essential oil；
Step 5: the petroleum ether liquid containing essential oil is heated, and obtained phegma is extraction of essential oil liquid.
Further, in step 2, vapo(u)rizing temperature is 70 DEG C.
Further, in step 2, distillation time is 3h~7h.
Further, in step 2, the concentration of sodium chloride solution is 0.01~1%.
Further, in step 3, the volume ratio of distillate and petroleum ether is 1:1.5~1:2.
Further, in step 2, the solid-liquid ratio of Jiang Miao powder and sodium chloride solution is 10:1~15:1.
The utility model has the advantages that compared with prior art, the invention has the advantages that the aerial stem of plant part Jiang Miao using ginger extracts ginger
Seedling derived essential oil not only meets the growing demand of consumer, while reducing essential oil price, improve social benefit and
Ecological benefits are solved because of the problem of putting Jiang Miao aside as useless cause environmental pollution and resource in Tanaka significant wastage, protection ring
Border.
Specific embodiment
The preferred embodiments of the present invention will be described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that so as to make a clearer definition of the protection scope of the present invention.
A kind of extracting method of Jiang Miao essential oil, comprising the following steps:
Step 1: the ginger Jiang Miao newly harvested is taken, in the sun naturally dry to constant weight；
Step 2: the Jiang Miao after drying is ground into Jiang Miao powder, crosses 70 meshes, sodium chloride solution, sodium chloride solution is added
Concentration be the solid-liquid ratio of 0.01~1%, Jiang Miao powder and sodium chloride solution be 10:1~15:1, stirring is placed on distilling apparatus
In, distillation obtains distillate, and vapo(u)rizing temperature is 70 DEG C, and distillation time is 3h~7h；
Step 3: being added petroleum ether in distillate, and the volume ratio of distillate and petroleum ether is 1:1.5~1:2, is extracted
It takes, extraction time is 10min~15min, obtains extract liquor；
Step 4: the petroleum ether liquid for extract liquor being extracted again containing essential oil；
Step 5: the petroleum ether liquid containing essential oil is heated, and obtained phegma is extraction of essential oil liquid.
Distillation extraction time is 6h, and the solid-liquid ratio of Jiang Miao powder and sodium chloride solution is that the concentration of 15:1 sodium chloride solution is
It when 0.45%, uses petroleum ether as extractant, extracts 2 times, the time extracted every time is 12min, obtained Jiang Miao essential oil yield
It is 0.229%.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
