Description
Technical field
The present invention relates to a kind of Trchosanthes kiriowii maxim seed oil expelling method.
Background technology
Seeds of Trichosanthes kirilowii is emerging medicine food dual-purpose snackfoods, and oleaginousness is up to 31% (band shell), and wherein unsaturated fatty acid content accounts for more than 2/3 of amount of total fat.Traditional Chinese medicine thinks, the Seeds of Trichosanthes kirilowii flavor is sweet, cold in nature, and removing heat from the lung and dissipating phlegm is arranged, the effect of laxation defaecation, and the scale development trichosanthes kirilowii Maxim seed oil has the market requirement widely.
At present, trichosanthes kirilowii Maxim seed oil extracts and still locates laboratory stage, mostly adopts the methods such as chemical reagent, enzymolysis and carbon dioxide upercritical fluid extraction.
Also someone adopts the oil expression method to obtain trichosanthes kirilowii Maxim seed oil, and its technique is generally: whole Seeds of Trichosanthes kirilowii is put into oil press zhai squeeze, this method technique is succinct, but extraction yield is lower, is only 60.5%.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of technique is simple and clear, safety non-pollution, cost is low, yield is high Trchosanthes kiriowii maxim seed oil expelling method.
In order to solve the problems of the technologies described above, the invention provides a kind of Trchosanthes kiriowii maxim seed oil expelling method, comprise the following steps successively:
1), shelling:
Seeds of Trichosanthes kirilowii is shelled, get Seeds of Trichosanthes kirilowii benevolence;
2), preheating:
Seeds of Trichosanthes kirilowii benevolence was in 60～80 ℃ of preheatings 40～50 minutes;
3), heat:
With step 2) Seeds of Trichosanthes kirilowii benevolence after the preheating of gained is in 160～180 ℃ of heating 17～23 minutes;
4), squeezing:
With step 3) Seeds of Trichosanthes kirilowii benevolence after the heat of gained puts into immediately oil press zhai and squeezes, and gets crude oil and oil meal;
5), the oil meal with gained squeezes in oil press zhai 1～3 time repeatedly; Get crude oil;
6), with step 4) crude oil and the step 5 of gained) crude oil of gained merges, and first filters (such as be the conventional filtration modes such as filter-cloth filtering or negative pressure leaching) or precipitation to remove residue; Then carry out high speed centrifugation in 5000～6000 rev/mins and separate, separating obtained sediment is removed, and the edible vegetable oil of gained is trichosanthes kirilowii Maxim seed oil.
As the improvement of Trchosanthes kiriowii maxim seed oil expelling method of the present invention, step 1) be:
To soak 3～4 hours in the warm water of Seeds of Trichosanthes kirilowii prior to 40～45 ℃, then with shell remover for melon seeds shelling (fan is raised except the melon seed cases relic), get Seeds of Trichosanthes kirilowii benevolence.
As the further improvement of Trchosanthes kiriowii maxim seed oil expelling method of the present invention, step 4) and step 5) in squeezing be: squeezed under the pressure of 0.4～0.6MPa 5～10 minutes.
As the further improvement of Trchosanthes kiriowii maxim seed oil expelling method of the present invention, step 3) the mode of heat for smoking.
After the trichosanthes kirilowii Maxim seed oil of gained of the present invention is cooled to normal temperature, can carry out in a conventional manner can.
Trchosanthes kiriowii maxim seed oil expelling method of the present invention has following key problem in technology point:
1, the shell of Seeds of Trichosanthes kirilowii is hard thin and crisp, ordinary method shelling difficulty, and the present invention can complete mechanical dejacketing with soaking 3～4 hours in 40～45 ℃ of warm water; Thereby raising oil yield.
2, Seeds of Trichosanthes kirilowii benevolence through preheating and heat, can make the peculiar taste of the trichosanthes kirilowii Maxim seed oil maintenance trichosanthes seed of final gained.
Seeds of Trichosanthes kirilowii benevolence after the heat of 3, squeezing while hot (soon step 3) gained is put into immediately oil press zhai and is squeezed), can improve oil yield more than 3%;
4, filtration separates to remove slag with high speed centrifugation and combines, and has improved the clarity of processed oil.
In sum, the present invention adopts physical method, and whole production process is without any chemical agent, and the product of gained---trichosanthes kirilowii Maxim seed oil gives off a strong fragrance, clear and bright safety.Method safety of the present invention is pollution-free, and cost is low, and yield is high, and technique is simple and clear, good reproducibility, and the clear and bright perfume (or spice) of product is strongly fragrant, has kept preferably the peculiar taste of trichosanthes seed, can be used for the scale production of trichosanthes kirilowii Maxim seed oil.
The trichosanthes kirilowii Maxim seed oil of gained of the present invention the analysis showed that through GC, and unsaturated fatty acid content is very high, accounts for more than 83.6% of amount of total fat, and wherein oleic acid 29.0%, linolic acid 29.4%, trichosanic acid 25.2%.
