Abstract
The invention discloses a process of extracting essential oil and oleoresin from the stalk of Chinese prickly ash, which belongs to the field of further processing of Chinese prickly ash. According to the process, the stalk of Chinese prickly ash is used as a raw material; the essential oil of Chinese prickly ash is extracted by using steam at first; and then the oleoresin of Chinese prickly ash is extracted by using a composite solvent. The process improves the comprehensive utilization rate of Chinese prickly ash and increases the profit ratio of Chinese prickly ash.
Description
Technical field
The invention belongs to Chinese prickly ash deep processing field, particularly from the Chinese prickly ash stalk, extract Japan pepper essential oil and xanthoxylum oleoresin.
Background technology
Chinese prickly ash is as a kind of general seasoning plant in food, and the owner is application space widely, especially Japan pepper essential oil and xanthoxylum oleoresin a kind of natural flavouring commonly used especially.Yet, source as Japan pepper essential oil and xanthoxylum oleoresin, all that application Chinese prickly ash particle is pulverized extraction essential oil and oleo-resinous, and the Chinese prickly ash stalk that contains equally some amount Japan pepper essential oil and xanthoxylum oleoresin is thrown away or, as consumer waste incineration, not only lost the pollution that a large amount of resources has also caused environment as waste.
Summary of the invention
For overcoming above-mentioned prior art deficiency, the invention discloses the technique of extracting essential oil and oleo-resinous from the Chinese prickly ash stalk, isolate Japan pepper essential oil and the xanthoxylum oleoresin of high value in waste, improved the comprehensive utilization ratio of Chinese prickly ash, promoted the profit margin of Chinese prickly ash.
The technical solution adopted in the present invention is a kind of technique of extracting essential oil and oleo-resinous from the Chinese prickly ash stalk, the steps include: originally to be used as the Chinese prickly ash stalk that waste material burns is raw material, at first the Chinese prickly ash stalk is dropped into to reactor, pass into steam in reactor, vapour volume is 10-20 cubes, distilled, time is 60-90 minutes, and then cooling recovered steam, be cooled to room temperature, by upper and lower two separate, upper strata is Japan pepper essential oil.The later Chinese prickly ash of distillation of essential oils stalk, by the water filtering, (normal hexane: ethyl acetate=6:4) shower 2-3 hours repeatedly obtains xanthoxylum oleoresin after the refine and reclaim solvent to add double solvents.
The invention has the beneficial effects as follows whole leaching process, that the Chinese prickly ash stalk of take originally as waste is raw material, at first extract Japan pepper essential oil, and then extraction xanthoxylum oleoresin, what two kinds of main components wherein were done extracts, greatly improve added value of product, created wide profit margin.
Embodiment
Embodiment 1, and the Shanxi Radix Campylotropis Hirtella (Herba Myrsines Africanae) Chinese prickly ash stalk of take is raw material, Chinese prickly ash is obstructed to 500kg and drop in reactor, and the steam that passes into 10 cubes is distilled, and the time is 60 minutes, and cooling recovered steam obtains Japan pepper essential oil 3kg after essential oil and water stratification; Then the water in the Chinese prickly ash stalk is leached, (normal hexane: ethyl acetate=6:4) circulation shower 2 hours obtains xanthoxylum oleoresin 55kg after the refine and reclaim double solvents to drop into double solvents.
Embodiment 2, and the Sichuan pericarpium zanthoxyli schinifolii stalk of take is raw material, Chinese prickly ash is obstructed to 500kg and drop in reactor, and the steam that passes into 20 cubes is distilled, and the time is 90 minutes, and cooling recovered steam obtains Japan pepper essential oil 4.2kg after essential oil and water stratification; Then the water in the Chinese prickly ash stalk is leached, (normal hexane: ethyl acetate=6:4) circulation shower 3 hours obtains xanthoxylum oleoresin 71kg after the refine and reclaim double solvents to drop into double solvents.
Embodiment 3, and the Shandong pericarpium zanthoxyli schinifolii stalk of take is raw material, Chinese prickly ash is obstructed to 500kg and drop in reactor, and the steam that passes into 15 cubes is distilled, and the time is 75 minutes, and cooling recovered steam obtains Japan pepper essential oil 3.6kg after essential oil and water stratification; Then the water in the Chinese prickly ash stalk is leached, (normal hexane: ethyl acetate=6:4) circulation shower 3 hours obtains xanthoxylum oleoresin 62kg after the refine and reclaim double solvents to drop into double solvents.
Claims (2)
1. a technique of extracting essential oil and oleo-resinous from the Chinese prickly ash stalk, is characterized in that: take the Chinese prickly ash stalk as raw material, at first in reactor, pass into steam, steam is 10-20 cubes, is distilled, and distillation time is between 60-90 minutes, then cooling recovered steam, be cooled to room temperature, by upper and lower two separate, upper strata is Japan pepper essential oil, the Chinese prickly ash stalk that distillation of essential oils is later, by the water filtering, add double solvents shower 2-3 hours repeatedly, obtain xanthoxylum oleoresin after the refine and reclaim solvent.
