Abstract
The invention discloses a degumming technology of fragrant oil-tea camellia seed oil. The degumming technology includes the following steps that 1, fragrant oil-tea camellia seed crude oil is poured to a degumming tank, a citric acid solution is added, and the mixture is stirred and subjected to an acid reaction to separate oil foots in the oil; 2, the oil-tea camellia seed oil subjected to oil foot separation is washed for the first time; 3, the oil-tea camellia seed oil subjected to oil water separation is washed for the second time; 4, the oil-tea camellia seed oil washed for the second time is poured to a vacuum drying tank and dried; meanwhile, a small amount of N2 is sprayed for writhing, and then filtering is carried out through dried filter paper. Compared with the prior art, the problem that the fragrant oil-tea camellia seed oil is poor in fragrance is solved; as the degumming temperature is low, losses of beneficial ingredients are small, and the quality and the fragrance of the tea oil are guaranteed; as the low-temperature vacuum method and the nitrogen writhing method are adopted, residual moisture is effectively removed, the transparency of the degummed oil-tea camellia seed oil is better, and the aim of the degumming technology is achieved.
Description
Technical field
The present invention relates to a kind of Degumming method, particularly a kind of scented oil tea-seed oil degumming technology.
Background technology
Existing camellia seed oil degumming technology, be imitate large oily complete processing, specifically: oil-tea camellia seed crude oil is heated to about 85 DEG C, the phosphoric acid adding 85% mixes with crude oil, and continuously stirring reacts about 45min; Add hot water, salt solution or white liquor again, react about 20min, colloid in oil or soap stock are separated; Oil after separation, adds the hot wash of about 95 DEG C, after oily water separation, enters vacuum drier drying; After dry winterizing, filter, be finished product after the assay was approved.
But be large degumming of oil technique due to what adopt, the feature not for this oil product is come unstuck, make the nutrient component damages of oil product comparatively large, the quality of oil product is not high yet; Meanwhile, be high vacuum dehydration under comparatively high temps due to what adopt, the flavor compound in oil is lost in a large number.
Therefore, a kind of scented oil tea-seed oil degumming technology of special needs, to solve above-mentioned existing Problems existing.
Summary of the invention
The object of the present invention is to provide a kind of scented oil tea-seed oil degumming technology, for the deficiencies in the prior art, make scented oil tea-seed oil nutrient component damages, the difficult problem that quality is not high is resolved, also solve oil product flavor compound and lose the difficult problems such as serious, ensure that the quality of such camellia seed oil.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of scented oil tea-seed oil degumming technology, it is characterized in that, it comprises the steps:
(1) delicate fragrance oil-tea camellia seed crude oil is squeezed into glue kettle, add citric acid solution, stir, after acid-respons, the oil foot in oil is separated;
(2) be separated the camellia seed oil after oil foot, carry out first time washing;
(3) by the camellia seed oil after oily water separation, secondary washing is carried out;
(4) camellia seed oil after secondary washing, squeezes into vacuum drying tank and carries out drying; Meanwhile, a small amount of N is sprayed into
2seethe, and then filter with the filter paper after drying.
In one embodiment of the invention, in above-mentioned steps (1), delicate fragrance oil-tea camellia seed crude oil is squeezed into glue kettle, add the citric acid solution of 25Be ° of the 0.15-0.3% accounting for crude oil total amount, first rapid stirring 5-10min, after being about 120min with 10rpm rotating speed low rate mixing again, add the NaCl solution low rate mixing 30min of 10%, the oil foot in oil is separated
In one embodiment of the invention, the citric acid solution of 25Be ° of the hot water adding 80 DEG C by the 5-8% of crude oil amount in above-mentioned steps (2) and the 0.005-0.02% that accounts for crude oil amount carries out short mix 4-6min, then low rate mixing 10-15min, oily water separation.
In one embodiment of the invention, in above-mentioned steps (3), add the NaCl solution of the 4-6% of 60 DEG C by the 8-10% of crude oil amount, short mix 4-6min, then low rate mixing 10-15min, is separated oil with water.
In one embodiment of the invention, carry out dry vacuum absolute pressure at the middle vacuum drying tank of above-mentioned steps (4) and be less than 300Pa.
In one embodiment of the invention, the oven dry filter paper being 1mm at above-mentioned steps (4) middle thickness filters.
The principle of scented oil tea-seed oil degumming technology of the present invention is: first adopt low temperature to come unstuck delicate fragrance oil-tea camellia seed crude oil, then carries out middle temperature, secondary washing; Tea oil after washing under low temperature, high vacuum, by spraying into a small amount of N
2carry out stripping, and then with the filter paper filtering of drying, absorb residual micro-moisture further.
Come unstuck owing to have employed low temperature, secondary is washed, thus is effectively stripped of the impurity in oil, effectively remains the volatile constituent in oil, the loss of micro-nutritive ingredient is avoided; Adopt low temperature, high vacuum adopt N
2stripping, not only have effectively achieved the moisture removed in oil, also makes the flavour ingredient of oil be retained preferably; With the filter paper filtering after oven dry, be not only thoroughly stripped of the residual moisture in oil, and ensure that the quality of oil product.
Scented oil tea-seed oil degumming technology of the present invention, compared with prior art, have employed precooling, cooling constant temperature, thus imperfect crystal formation in crystallisation process is tailed off, improve the effect of crystallization, be effectively stripped of the solid fat of higher melt, have employed that low temperature comes unstuck, the washing of middle temperature secondary, the cold dehydration of high vacuum and dry filter paper dry technology, thus the flavour ingredient of oil product and micro-nutritive ingredient are effectively retained, improve the quality of product, realize object of the present invention.
The detailed description and obtaining that feature of the present invention can consult the graphic and following better embodiment of this case is well understood to.
Accompanying drawing explanation
Fig. 1 is the process flow sheet of scented oil tea-seed oil degumming technology of the present invention.
