Description
Technical field:
The present invention relates to a kind of method of extracting bark of eucommia fruit oil from bark of eucommia fruit, belong to food processing field.
Background technology:
The bark of eucommia is China's rare traditional Chinese medicine, and gutta-percha tree is at the cultivation history of the existing two thousand years of China, and resource is richly endowed by nature, and approximately 5,000,000 mu of national existing plantation areas, account for world's bark of eucommia total resources more than 95 percent.
The eucommia bark seed of results far exceedes breeding and afforestation needs, has formed a kind of new resource.In eucommia bark seed, contain abundant eucommia ulmoides seed oil, whole seed oil-containing 10% left and right, shelling oil-containing 30% left and right.In eucommia ulmoides seed oil, the linolenic content of a-exceedes 50%, and a-linolenic acid is one of lipid acid of needed by human, has effect of reducing blood-fat step-down, is therefore a kind of nutrition oil.
The oily extracting method of existing bark of eucommia fruit mainly contains following several:
The first: mechanical expression method: bark of eucommia fruit through screening, dry, softening, steam fry, squeezing obtains bark of eucommia fruit oil.Milling process is produced bark of eucommia fruit oil, generally not with an organic solvent, does not have organic solvent residual, product safety, health, pollution-free.But it is lower that milling process is prepared the oily oil yield of bark of eucommia fruit, (Wang Lan, horse Berlin, etc., eucommia ulmoides seed oil extraction process [J] conventionally to only have 20-25%.Xibei Forest College's journal, 2003,18 (4)).And owing to needing Eucommia seed high-temperature heating treatment before squeezing, many compositions in bark of eucommia fruit oil are easily heated and oxidative deformation occur, easily be heated and oxidative deformation occurs, cause grease color obfuscation, oil is poor, and particularly one of bark of eucommia fruit main body of oil a-linolenic acid, contains three two keys, very easy destroyed after being heated, content reduces.
The second: organic solvent lixiviation process: with organic solvent extraction, reclaim organic solvent and can obtain slightly oil of Eucommia Fruit after Eucommia seed is pulverized, then through refining, obtain bark of eucommia fruit oil.Conventional organic solvent has sherwood oil, normal hexane etc.Shortcoming is, adopts these organic solvent extraction, and organic solvent is difficult to remove completely, often has organic solvent residual, and organic solvent lixiviation process exists larger security risk, higher to equipment and production safety management expectancy.
The third: supercritical carbon dioxide extraction method: drop in pot for solvent extraction after bark of eucommia fruit is pulverized, through lixiviate, decompression, separation, can obtain eucommia ulmoides seed oil, gained oil colours pool is better.But supercritical carbon dioxide extraction equipment price is higher, and early investment is larger.
The 4th kind: Enzymatic Extraction: bark of eucommia fruit adds the extractions such as flooding, enzyme-added enzymolysis, sherwood oil after pulverizing, recovery solvent obtains bark of eucommia fruit oil, and Enzymatic Extraction rate is high, mild condition, product appearance proterties and quality better.But the control of Extraction Processes condition is strict, high to production operation requirement, and the price of enzyme is higher, and production prices are higher.
, all there is the problem that is difficult to overcome based on extraction scheme in the oily existing extracting method of above-described bark of eucommia fruit, cause reducing extraction cost and improve product quality being difficult to take into account simultaneously.Therefore, improve the oily extraction process of existing bark of eucommia fruit, in reducing extraction cost, guarantee product quality, be very important.
Summary of the invention:
Object of the present invention: propose that the oily extraction yield of a kind of bark of eucommia fruit is high, superior product quality, process program that production cost is low.
Through a large amount of experiment and research, the present invention has found a kind of method of destroying oil sac structure in bark of eucommia fruit, different from published prior art is, the present invention is take Eucommia seed as raw material, before squeezing, utilize the nutritive ingredient of edible mushrooms degraded, absorption raw material, destroy the oil sac structure in raw material, thereby reach the exposure of bark of eucommia fruit oil, bark of eucommia fruit oil is more easily squeezed out.
The invention provides a kind of method of extracting bark of eucommia fruit oil from Eucommia seed, it is characterized in that the oil sac structure in the degraded of raw material edible bacterium, destruction raw material before extraction bark of eucommia fruit oil, comprise following processing step:
(1) pre-treatment: bark of eucommia fruit is crushed to 10-80 order.
(2) edible mushrooms degraded for step (1) gained material, absorption nutrition, destruction oil sac structure: material inoculation edible mushrooms, mix rear stacking, utilize edible mushrooms degraded, destroy the oil sac structure in material.
(3) squeezing of bark of eucommia fruit oil: make crude product bark of eucommia fruit oil through edible mushrooms material after treatment through squeezing in step (2).
(4) bark of eucommia fruit oil is refining: the crude product bark of eucommia fruit oil in step (3) is removed to residue through natural subsidence or centrifugal etc., clarify, transparent bark of eucommia fruit is oily.
The present invention has following useful effect:
(1) the present invention, before squeezing bark of eucommia fruit oil, takes the nutritive ingredient of edible mushrooms degraded, absorption raw material, destroys the oil sac structure in raw material, thereby reaches the exposure of bark of eucommia fruit oil, and bark of eucommia fruit oil is more easily squeezed out, and oil yield is high.
(2) the present invention is before squeezing bark of eucommia fruit oil, and oil plant does not need high-temperature heating treatment, and the composition of the destructible that is heated in grease can be not destroyed as a-linolenic acid etc., and oil quality is good.
(3) technique of the present invention is simple, equipment investment is low.
Accompanying drawing explanation
Fig. 1 represents process flow sheet of the present invention.
Implement best mode of the present invention:
Before inoculation edible bacterium, Eucommia seed need to be pulverized, be beneficial to edible mushrooms raw material is contacted fully.But if raw material pulverizing is too thin, after material stacking, the space of storeroom is too little, is unfavorable for the breeding of edible mushrooms.Preferably raw material pulverizing is arrived to 10-80 order, particularly preferably raw material pulverizing is arrived to 20-40 order.
In the process of the degraded of step (2) edible mushrooms, absorption material nutrient component, destruction oil sac structure, first need to carry out the inoculation of edible mushrooms.For the bacterial classification of edible mushrooms, be not particularly limited, can be wherein one or more such as flat mushroom strain, mushroom strain, needle mushroom bacterial classification.Consider preferably flat mushroom strain from biological efficiency.
For edible mushrooms degraded in step (2), absorb the nutritive ingredient of raw material, the time of destroying oil sac structure, take oil plant outward appearance adularescent mycelium with smell slight ethanol smell as degree.
For the squeezing of bark of eucommia fruit oil in step (3), adopt 40-80 ℃ of squeezing of conventional pressing method control pressing temperature, preferably 50 ℃ of pressing temperatures.
For refining of bark of eucommia fruit oil in step (4), due to low temperature pressing technique, foreign matter content is few, therefore only needs to filter after natural subsidence, also can adopt centrifuging to separate and remove impurity.
