Abstract
The invention discloses a tea seed oil low-temperature physical cold squeezing process, which mainly comprises: allowing tea seeds to undergo postripeness, selecting seeds, performing cold squeezing to obtain crude oil, and subjecting crude oil to coarse filtration, low-temperature filtration and medium-temperature dehydration and decolorization in turn, wherein the medium-temperature dehydration and decolorization is implemented by filling tea seed oil obtained after low-temperature filtration in a dehydration barrel, stirring, adding water in an amount which is 3 to 7 percent based on the weight of the tea seed oil, stirring till there is no water mist in the dehydration barrel, performing multiple filtration, stirring in a second dehydration barrel till water vapor is dewatered and decolorized till the water content is 0, opening a gate at 80 to 100 DEG C, performing multiple filtration, and obtaining finished tea seed oil. In the invention, through the medium-temperature evaporation water vapor dehydration and decolorization treatment, pollution caused by direct contact of chemical matters such as carclazyte and the tea seed oil is avoided, nutrients such as tocopheronic acid, squalene and sterol, as well as active ingredients and fragrance in the tea seed oil are retained; the obtained tea seed oil shows the natural yellow and clear appearance color and luster of tea seed oil; and the quality of the obtained tea seed oil exceeds the GB11765-2003 standards for first-class squeeze oil.
Description
Technical field
The present invention relates to the tea-seed oil technical field, particularly relate to the low-temperature physical cold squeezing process of tea-seed oil.
Background technology
At present, the edible more vegetables oil of people is tea-seed oil and rapeseed oil.Tea-seed oil is to adopt the seed in the oilseed plant tea seed cone to claim again the tea seed to be prepared from, the usual method of tea seed oil expression is: the tea oil cone after will gathering dries, broken shell, taking out the tea seed dries, through rolling embryo, steam and fry, leach, squeezing, the basic production operations such as refining are produced, in the method, the tea seed will be fried operation through steaming, the high temperature that steaming is fried is easy to lose the nutritive ingredient in the oil, the fragrance of active substance and tea seed itself, and traditional refining process also will carry out filler vacuum-drying to the coarse tea oil that comes of squeezing out, vacuum decoloration, the processing such as high temperature high vacuum deodorization, equally can be to the tocopherol in the coarse tea oil, squalene, the useful composition such as sterol causes a large amount of losses, in addition, contain more various impurity such as tea seed shell bits in the coarse tea oil, phosphatide, the acid of free-fat fat, carbohydrate, moisture content, protein and their degradation product, oxide compounds etc. not only can affect oily appearance luster, also can have influence on the interior quality of oil.
Chinese patent ZL200610031452.1 discloses a kind of " tea-seed oil physical low-temperature cold-squeezing process ", the coarse tea oil that squeezes is made refining tea-seed oil through multi-filtering-filter at low temperature-adding atlapulgite filler-dehydration-technical process such as decolouring, can not lose the nutritive ingredient in the oil in the method refining process, the refining tea oil that obtains presents the limpid appearance luster of oil colours, but the method has added carclazyte in refining process, carclazyte is when carrying out adsorption bleaching, also can adsorb the nutritive ingredient in the tea-seed oil, active substance and lose the distinctive delicate fragrance of tea-seed oil itself, in addition, the adding of carclazyte has caused direct pollution so that chemical substance directly contacts with tea-seed oil to tea-seed oil.
Summary of the invention
Technical problem to be solved by this invention is to add the defective that the carclazyte filler brings when overcoming the tea-seed oil refining, a kind of low-temperature physical cold squeezing process of tea-seed oil is provided, this processing method is simple and easy to do, do not lose the nutritive ingredient of tea oil in the expressing process, have tea-seed oil with the smell and the flavour that have, refining process does not produce pollution.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
The low-temperature physical cold squeezing process of tea-seed oil of the present invention, mainly comprise the after-ripening of tea seed, select seed, cold press obtains crude oil, the crude oil coarse filtration, filter at low temperature and dehydration and decolorization step, described dehydration and decolorization is middle temperature steam dehydration and decolorization: it is the dehydration barrel of 80～120kpd that the tea-seed oil behind the filter at low temperature is placed vacuum tightness, at 60～90 ℃, stir under the condition of rotating speed 50～70r/min, then the water that adds tea-seed oil 3～7% weight, water temperature is 9～18 ℃, be stirred in the dehydration barrel without till the water smoke, enter the second dehydration barrel behind the multi-filtering, adjust the stirrer rotating speed greater than 65r/min, under 100～130 ℃ of conditions, carry out the water vapour dehydration and decolorization, then be cooled to 70～100 ℃, open the dehydration barrel breaker, get the finished product tea-seed oil behind the multi-filtering.
Preferably, above-mentioned middle temperature steam dehydration and decolorization is: it is the dehydration barrel of 90～110kpd that the tea-seed oil behind the filter at low temperature is placed vacuum tightness, at 63～67 ℃, stir under the condition of rotating speed 55～65r/min, then the water that adds tea-seed oil 4～6% weight, water temperature is 9～12 ℃, be stirred in the dehydration barrel without till the water smoke, entering vacuum tightness behind the multi-filtering is the second dehydration barrel of 90～110kpd, adjust stirrer rotating speed 65～80r/min, under 110 ℃～120 ℃ conditions, carry out the water vapour dehydration and decolorization, be cooled to 80 ℃～100 ℃, open the dehydration barrel breaker, get the finished product tea-seed oil behind the multi-filtering.
Best, temperature steam dehydration and decolorization step is in the low-temperature physical cold squeezing process of aforementioned tea-seed oil: it is the dehydration barrel of 100kpd that the tea-seed oil behind the filter at low temperature is placed vacuum tightness, at 65 ℃, stirred 1 minute under the condition of rotating speed 60r/min, then the water that adds tea-seed oil 5% weight, water temperature is 9～12 ℃, be stirred in the dehydration barrel without till the water smoke, entering vacuum tightness behind the multi-filtering is the second dehydration barrel of 100kpd, adjust stirrer rotating speed 65～70r/min, under 110 ℃～120 ℃ conditions, carry out the water vapour dehydration and decolorization, then tea-seed oil is changed over to insulated tank and be cooled to 80 ℃～100 ℃, open the insulated tank breaker, get the finished product tea-seed oil behind the multi-filtering.
Compared with prior art, the present invention does not add the carclazyte filler when refining tea seed crude oil, and warm vaporize water steam dehydration and decolorization is processed in adopting, avoided the chemical substances such as carclazyte directly to contact the pollution that brings with tea-seed oil, can not lose tocopheronic acid in the tea-seed oil, separate the nutritive ingredients such as MF59, sterol, active substance and distinctive delicate fragrance itself, the gained tea-seed oil presents the yellow limpid appearance luster of tea-seed oil itself, is better than GB11765-2003 one-level Squeezing Tea Oil standard.
