Abstract
The invention discloses a process for preparing soybean oil by a pressing method. The process includes the steps: magnetically separating soybean, mixing the soybean, houttuynia cordata, broadleaf holly leaves and roxburgh rose, adding 8-10 times of water, decocting the mixture until the soybean is thoroughly cooked, and fishing out and draining the soybean; drying the treated soybean at the temperature of 60-80 DEG C until the water content of the soybean is 10-12%, and then crushing the soybean; mixing soybean flour and camellia seeds and then conveying the mixture into a presser for pressing oil, controlling the temperature of a barrel to range from 80 DEG C to 100 DEG C, and controlling outlet oil temperature to range from 60 DEG C to 80 DEG C to obtain crude oil; refining the crude oil to obtain finished soybean oil. The soybean oil has a health conditioning function and further has fragrance of tea.
Description
Technical field
The present invention relates to vegetables oil preparation technique field, specifically, relate to the technique that a kind of milling process prepares soybean oil.
Background technology
Soybean oil is the one oil extracted from soybean seeds, and soybean oil is faint yellow, as clear as crystal, and sediment-free, matter measured soybean oil color is all more shallow.The Fatty acid compositions of soybean oil is better, and it contains abundant linolic acid, and linolic acid is the lipid acid of needed by human, has important physiological function.Linolic acid has the effect of significant preventing cardiovascular disease, and can reduce serum cholesterol content, containing a large amount of vitamin-E, vitamins D and abundant Yelkin TTS in soybean oil, is all highly profitable to HUMAN HEALTH.Child lacks linolic acid, and not only skin can become dry, and the scales of skin that peel off thickens, and grows and can become slow; The elderly lacks linolic acid, can cause cataract and cardio cerebrovascular affection.In addition, the digestibility of human body to soybean oil is high, and up to 97%, so the soybean oil excellent edible oil that to be a kind of nutritive value very high, soybean oil output is maximum in grease in the world.
At present, the preparation technology of soybean oil mainly contains milling process and lixiviation process, lixiviation process is the principle of application leaching, with food grade solvent to the spray of oil plant and action of soaking, the method of grease is proposed from oil plant, concrete technical process is: cleaning → broken → soften → roll embryo → leaching → evaporation → stripping → crude oil of soybean → refining → soybean oil, current employing solvent oil (No. six petroleum naphthas)) glyceride stock is carried out high temperature extraction after fully soaking, through " six take off " technique (i.e. degreasing, come unstuck, dehydration, decolouring, deodorization, depickling) process, its advantage is that oil yield is high, production cost is low, but existing lixiviation process is in leaching process, leaching agent can remain in crude oil, cause the of poor quality of crude oil, and the leaching yield of oil is still on the low side, therefore, need to improve extract technology, improve production management.The technical process of milling process is: clear assorted → broken → softening → soft embryo → steamings fry → squeezing → refining, refining be by crude oil of soybean through " six is de-" technique (i.e. degreasing, come unstuck, dewater, decolour, deodorization, depickling) process.Milling process can retain the giving off a strong fragrance taste of crude oil in larger degree, but the well cuts produced is more, and oil yield is lower.
Summary of the invention
In view of this, the object of this invention is to provide the technique that a kind of milling process prepares soybean oil, low to solve prior art oil yield, the soybean oil quality of processing low and exist technical problem.
The present invention solves the problems of the technologies described above by the following technical programs:
Milling process prepares a technique for soybean oil, comprises the following steps:
(1) Soybean Pretreatment: first by soybean magnetic separation, then well-done to soybean by adding 8 ~ 10 times of soak by water after soybean, Herba Houttuyniae, Leaf of Chinese Holly and Rosa roxburghii mixing, soybean is pulled out and drains;
(2) dry, pulverize: being adopted by the soybean after process in step (1) temperature of 60 ~ 80 DEG C to dry to its moisture content is 10 ~ 12%, then pulverizes, obtains soyflour;
(3) squeeze: send in squeezing machine after being mixed with camellia seed by soyflour and extract oil, controlling to squeeze bore temperature is 80 ~ 100 DEG C, and oil outlet temperature is 60 ~ 80 DEG C, obtains crude oil;
(4) refined soybean oil: weight ratio crude oil being adjusted water oil is after 6 ~ 10:100, this oil-water mixture is warming up to 50 ~ 58 DEG C, normal temperature is cooled to after hydration degum 12 ~ 15min, crude oil after degumming process is placed in wavelength is 300 ~ 350nm, strength of current is 4 ~ 6A, temperature is process 40 ~ 60min under the condition of 40 ~ 50 DEG C, then temperature be 160 ~ 180 DEG C, vacuum tightness is distill 60 ~ 70min in the distillation plant of 180 ~ 190Pa to carry out deodorization, namely obtains soybean oil finished product.
Described magnetic separation joins in magnetic separator by soybean, removes the impurity such as metal, stone and the dust in soybean.
In described step (1), the weight ratio of soybean, Herba Houttuyniae, Leaf of Chinese Holly and Rosa roxburghii is 100:(1 ~ 2): (0.5 ~ 1): (2 ~ 5).
In described step (2), the temperature of 70 DEG C oven dry is adopted by the soybean after process in step (1) to be 11% to its moisture content.
In described step (3), first camellia seed being crushed to fineness is mix with soyflour after 60 ~ 100 orders to extract oil again.
In described step (3), the weight ratio of soyflour and camellia seed is 100:(4 ~ 6).
In described step (3), the temperature controlling to squeeze thorax is 90 DEG C, and oil outlet temperature is 70 DEG C.
In described step (4), weight ratio crude oil being adjusted water oil is after 8:100, this oil-water mixture is warming up to 55 DEG C, normal temperature is cooled to after hydration degum 14min, crude oil after degumming process is placed in wavelength is 320nm, strength of current is 5A, temperature is process 50min under the condition of 45 DEG C, then temperature be 170 DEG C, vacuum tightness is distill 65min in the distillation plant of 183Pa to carry out deodorization, namely obtains soybean oil finished product.
Beneficial effect of the present invention is:
First, the present invention is by decocting soybean, Herba Houttuyniae, Leaf of Chinese Holly and Rosa roxburghii mixing, benefit materials in Herba Houttuyniae, Leaf of Chinese Holly and Rosa roxburghii is incorporated in soybean oil naturally, this soybean oil is not only made to have more healthy opsonization, and the fragrance of soybean oil can also be increased, make the fragrance containing tea in soybean oil.
Secondly, because the oleaginousness of soyflour is higher, squeeze in oil press zhai fuel-displaced after become very satiny, in squeezing machine, velocity of flow is very fast, also the time be namely squeezed in squeezing machine is relatively short, the present invention is by squeezing soyflour and camellia seed mixing, the time that soyflour stops in squeezing machine can not only be extended, the grease in soybean is made more to be squeezed out, improve the oil yield of soybean, and containing materials such as abundant tea-polyphenol in camellia seed, can enter in grease in expressing process, thus make the nutrition of soybean oil abundanter, soybean oil is with light tea smell.
Again, pressed oil decolours by the present invention under certain illumination condition, effectively can not only remove the pigment in soybean oil and toxin, make the color of soybean oil more shallow, for faint yellow and limpid bright, and the high active substance that can not destroy in soybean oil, further increase the quality of soybean oil.
