Description
Technical field
The present invention relates to technical field of plant extraction, in particular to a kind of fructus cannabis oil and preparation method thereof.
Background technique
Fructus cannabis is the dry mature seed of Cannabis moraceae plants, is distributed widely in China northeast, North China, south China etc.
Ground, taste is dry, mild-natured, has tonifying middle-Jiao and Qi, the effect of enriching yin qi-restoratives.Modern research shows that fructus cannabis is full of nutrition, it is rich in albumen
Matter, grease and dietary fiber etc. have the effects that good reducing blood lipid, anti-inflammatory, anti-oxidant, improvement memory, it is strong to meet people
The pursuit of health diet.Fructus cannabis oil is a kind of grease based on unsaturated fat pinolenic acid, linoleic acid and alpha-linolenic acid, for
The disease incidence of the diseases such as hypertension, heart disease is reduced, promotes human health and plays a very important role.Fiery flaxseed oil can be used as Gao Pin
The functional grease of matter, development and application prospect are very wide.
Fructus cannabis oil as Fructus Cannabis extract, tetrahydrocannabinol containing micro remaining (△ 9-THC, hemp it is main
Toxic component).Disposable excessive edible hemp benevolence oil even will appear toxic reaction, and less serious case shows as that dizzy, thirsty, mouth is numb,
Phenomena such as severe one will appear stupor, be sunk into sleep.It is provided according to European Union, tetrahydrocannabinol content just permits not higher than 0.3% in fructus cannabis
Perhaps it is planted and edible, the content of tetrahydrocannabinol is no more than 10mg/kg and just meets what human body was easily born in finished product fructus cannabis oil
Threshold limit values, and the country never has relevant criterion for the content of tetrahydrocannabinol in fructus cannabis oil.According to the literature, generally
Be generally 47mg/kg without the content of tetrahydrocannabinol in the fiery flaxseed oil of heat treatment, this extreme influence fructus cannabis oil it is wide
General application and deep development.
Existing patent CN104031736A discloses a kind of preparation method of the fructus cannabis oil of low tetrahydrocannabinol content, can
Tetrahydrocannabinol content in fructus cannabis oil is reduced to 4mg/kg, but still can not achieve and completely remove.Although in addition, having at present
More fructus cannabis oil preparation process, but generally process is tedious, prepared fructus cannabis oil quality is not high, and stability is poor.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of fructus cannabis oil and preparation method thereof, so that the preparation side
Method can eliminate the tetrahydrocannabinol in fructus cannabis oil, and have high oil recovery and high-quality；
Another object of the present invention is that a kind of fructus cannabis oil and preparation method thereof is provided, so that described state preparation side
Method can significantly reduce the acid value (acid value) and peroxide value of fructus cannabis oil, improve fructus cannabis oil stability.
For achieving the above object, the invention provides the following technical scheme:
A kind of preparation method of fructus cannabis oil, comprising:
The numb seed cleaning removal of impurities of step 1, fire, shelling, obtain the fructus cannabis for being free of kernel clothing；
Step 2 carries out liquid nitrogen cryogenics crushing to fructus cannabis；
Smashed fructus cannabis is carried out hydraulic cold pressing by step 3, obtains fructus cannabis virgin oil；
Step 4, the fructus cannabis virgin oil winterization at low temperature, are then filtered, and obtain fructus cannabis oil.
Tetrahydrocannabinol cannot be completely removed for current fructus cannabis oil technique, and in quality and stability it is deficient
Scarce problem, the present invention crushes cooperation low temperature winterization using liquid nitrogen cryogenics, then again together with the shelling by optimization, hydraulic low temperature
The techniques such as squeezing, eliminate tetrahydrocannabinol, and significantly reduce the acid value (acid value) and peroxide value of fructus cannabis oil, improve
Oil product stability.
Preferably, shelling of the present invention is using laser cutting and squeezes shelling；Wherein, the laser cutting is in function
Rate 6W~50W is cut by laser under the conditions of rate 5mm/s~35mm/s, be cut to fiery numb seed cutting width be 0.5mm~
3.5mm；In the specific embodiment of the invention, the power is 40W or 50W, and the rate of cutting is 15mm/s or 25mm/s,
The cutting width is 1.8mm, 2.5mm or 3.5mm.
Preferably, step 3 are as follows:
Hydraulic cold pressing is carried out to smashed fructus cannabis, embryo piece is smashed to pieces mixing after squeezing and carries out repeating to squeeze again obtaining
Obtain fructus cannabis virgin oil.It is highly preferred that carrying out hydraulic cold pressing, pressure 30MPa to the smashed fructus cannabis of 2kg~14kg
~80MPa, temperature are 30 DEG C~70 DEG C, smash embryo piece to pieces mixing after squeezing every time and squeeze 2-5 acquisition fructus cannabis first squeezing repeatedly
Oil.In the specific embodiment of the invention, the inventory of the smashed fructus cannabis is 1kg, 8kg or 12kg, the pressure
For 55MPa or 60MPa, the temperature is 30 DEG C, 45 DEG C or 55 DEG C, and the number of squeezing repeatedly is 3 times or 4 times.
Preferably, the winterization is in 0 DEG C~6 DEG C 24~48h of standing；Wherein, winterization temperature is specially 0 DEG C or 4 DEG C,
The winterization time is 36h or 48h.
Preferably, the filtering uses 0.1~1.0 μm of filter core, filter pressure is 0.05~0.30Mpa.
Fructus cannabis oil is prepared according to preparation method of the present invention, there is the distinctive smell of fructus cannabis oil and flavour, no tapinoma-odour
And other peculiar smell, it is clarification, transparent faint yellow；Acid value is only 1.45-1.65 (KOH, mg/g), and peroxide value is only 0.394-
0.788mmol/kg stability height is easy to store；Rich in unsaturated fatty acid, wherein linoleic acid content is up to 50%, and is free of four
Hydrogen cannabinol noxious material.As a result, the present invention also provides a kind of fructus cannabis oil for having preparation method of the present invention preparation,
Without tetrahydrocannabinol.
From the above technical scheme, present invention adds liquid nitrogen cryogenics disintegrating process, cooperate winterization and have passed through optimization
The techniques such as shelling, hydraulic cold pressing, eliminate tetrahydrocannabinol, and significantly reduce the acid value in fructus cannabis oil and mistake
Oxidation number, stability are improved；Meanwhile integrated artistic of the present invention is simple, oil yield is up to 40% or more, is rich in unsaturated lipid
Fat acid, quality are high.
