Abstract
The present invention relates to a kind of preparation method of injection tea-seed oil, main technical points are to choose cold pressing to squeeze level-one tea-seed oil as experiment material, measure tea-seed oil quality index.Using molecularly distilled, in 20 DEG C of 0.5~2.5Pa of vacuum degree, condensation temperature, 120 DEG C~200 DEG C of vapo(u)rizing temperature reduces tea-seed oil acid value and peroxide value under feed rate 0.5mL/min~2mL/min, knifing rotating speed 100r/min~250r/min.Using alkaline process deacidifying process, 20g depicklings tea-seed oil adds water 5mL in excess alkali quantity 0.05%~0.3%, 40 DEG C~70 DEG C of alkali refining temperature, and tea-seed oil acid value is reduced under alkali refining time 20min~50min.Measure injection tea-seed oil quality index.Present invention consuming solvent is few, and neutral oil loss amount is small, and processing method is more economical, environmentally friendly.
Description
Technical field
The present invention relates to functional grease development technique field more particularly to a kind of preparation methods of injection tea-seed oil.
Background technology
Oil for injection is the urgent patient that some are unable to oral feeding and superelevation metabolism, by way of intravenous injection
The grease of intake or the oils that can be used as injection solvent.Since oil for injection and tissue and blood vessel are in direct contact,
On raw material must its have no stimulation to human body, this requires oil for injection moderate stimulation substance is controllable, environment is mild, resonable
Change free from admixture as possible in index, pH environment and anti-oxidant etc. is suitble to tissue environment.If containing miscellaneous in oil for injection
Matter can cause the pyrogen reaction of body, severe patient that will threaten the life security of patient.Oil for injection selects the reason of tea-seed oil
It is oil tea, is the distinctive woody oil tree species of China, belongs to one of four big traditional oil trees.It is extracted from Seed of Camellia oleifera
Tea-seed oil, similar to the aliphatic acid of olive oil composition, using oleic acid as main fatty acid, aliphatic acid composition is reasonable, and has " east olive
The title of olive oil ".Tea-seed oil smoke point is high, and thermal stability is good.Oil for injection is prepared both at home and abroad at present mainly to use degumming, depickling, take off
Prepared by the traditional plants olein sweetening process such as color, deodorization, the method environmental pollution is big, and consumption solvent is more, neutral oil loss amount
Greatly.
Invention content
It is an object of the invention to overcome the deficiencies in the prior art, provide a kind of preparation method of injection tea-seed oil.This
The technical solution of invention is：
A kind of preparation method of injection tea-seed oil, tea-seed oil used are physics cold pressing squeezing level-one tea-seed oils, including as follows
Step：
1) the quadratic component way of distillation is used, condition is 0.5~2.5Pa of vacuum degree, 20 DEG C of condensation temperature, vapo(u)rizing temperature 120
DEG C~200 DEG C, feed rate 0.5mL/min~2mL/min, knifing rotating speed 100r/min~250r/min, obtained depickling tea
Seed oil；
2) alkaline process deacidifying process, the depickling tea-seed oil for taking 20g steps 1) to obtain is used to be added fewer than depickling tea seed oil quality
0.05%~0.3% alkali adds water 5mL, 40 DEG C~70 DEG C, alkali refining time 20min~50min of alkali refining temperature, obtained tea seed
Oleic acid value is 0.05mg/g, and peroxide value 0.52mmol/kg, alkali refining yield is 70%.
Further, step 1) the first time molecularly distilled, 160 DEG C of vapo(u)rizing temperature, feed rate 0.5mL/min are scraped
Film rotating speed 200r/min.
Second of molecularly distilled of the step 1), 200 DEG C, feed rate 0.5mL/min of vapo(u)rizing temperature, knifing rotating speed
200r/min.Obtained depickling tea-seed oil acid value is 0.18mg/g, peroxide value 0.52mmol/kg；
Further, fewer than depickling tea-seed oil 0.1% alkali, alkali refining temperature 50 C, alkali is added in step 2) alkaline process deacidifying process
Refine time 30min.
Further, 0.013 at the tea-seed oil absorbance 270nm obtained, acid value 0.045mgKOH/g, peroxide value
0.517mmol/kg, saponification number 182.330mgKOH/g, unsaponifiable matter value 0.302%.
By alkaline process deacidifying process, obtained tea-seed oil acid value 0.045mgKOH/g<0.1mgKOH/g meets《Middle traditional Chinese medicines
Allusion quotation》Oil for injection standard.On peroxide value without influence, alkaline process depickling oil peroxide value is 0.517mmol/kg for alkaline process depickling.
Physics cold pressing is used to squeeze level-one tea-seed oil as research object in this technology, by molecular distillation, alkaline process deacidifying process,
Injection tea-seed oil is prepared, processing method is more economical, environmentally friendly.Molecularly distilled is better than traditional refinery practice, on the one hand detaches
Condition of high vacuum degree is utilized in the process, is not used solvent, is avoided toxicity problem.On the other hand, separation temperature is low, makes heat-sensitive substance
Loss reduce.Therefore the useful molecules way of distillation reduces the acid value and peroxide value of tea-seed oil.It is sent out using common method of refining
Now, peroxide number or acid value one of which or two standards for not complying with oil for injection.We use molecularly distilled
Peroxide number is reduced to 0.52mmol/kg, oil for injection standard is reached, acid value is reduced to 0.18mg/g, acid value
It is undesirable, but further use alkaline process depickling that the reduction of its acid value is made to reach oil for injection standard and to peroxide number
Do not influence.The acid value of the first step drops to 0.18mg/g and makes the depickling of second step subtraction can not only further decrease acid value to reach
It is required that not influencing peroxide number also.
The advantages and positive effects of the present invention are：
(1) selection tea-seed oil has advantage.Oil tea is the distinctive woody oil tree species of China, belongs to four big woody oleiferous plants
One of plant.The tea-seed oil extracted from Seed of Camellia oleifera, it is similar to olive fatty acid oil composition, using oleic acid as main fatty acid,
Aliphatic acid composition is reasonable, and has the title of " east olive oil ".Tea-seed oil smoke point is high, and thermal stability is good.
(2) tea seed fatty acid oil composition is similar to olive oil, can be gone out for oil for injection with export substitution injection olive oil
Mouth provides technical support.
(3) tea-seed oil is prepared into injection tea-seed oil, promotes tea-seed oil to be developed from food service industry to pharmaceuticals industry, both may be used
To develop tea-seed oil new product, and improve its added value.
(4) pass through tea-seed oil acid value 0.045mgKOH/g made from this method<0.1mgKOH/g meets《Chinese Pharmacopoeia》Note
It penetrates and uses oil standard.On peroxide value without influence, alkaline process depickling oil peroxide value is 0.517mmol/kg, meets injection for alkaline process depickling
Use oil standard.Therefore the tea-seed oil obtained can be used for injecting.
