Abstract
The present invention relates to flocculation material removal methods in a kind of sesame oil, specially：Surfactant is added in preliminary filtered sesame crude oil and is well mixed, freezing is filtered after standing.The surfactant is food grade sucrose fatty acid ester, and HLB value is 3 or 5；The addition of surfactant is 0.1-the 0.5% of sesame crude oil weight.The removal methods are simple, easy to operate, and surfactant is cheap and easy to get, also substantially reduce the time of repose in sesame oil refining process.The sesame oil treated using the inventive method keeps not muddy under the conditions of being placed in low temperature or for a long time, is also separated out without flocculate.
Description
Technical field
The invention belongs to sesame oil processing technique field, flocculate removal methods in more particularly to a kind of sesame oil.
Background technology
Sesame oil is a kind of flavor grease that our people enjoys a lot, and its traditional mode of production is using water substitution system
The ground sesameseed oil for taking.With the development and the improvement of technique of modern science and technology, many sesame oil manufacturing enterprises all using hot moulding,
The production technologies such as press filtration.But whether using which kind of production technology, the operations such as filtering clarification are required for, to avoid Oleum Sesami from existing
There is sediment in bottom of bottle cohesion in prolonged shelf life.
Despite the use of the operations such as filtering are precipitated, but with the extension of storage time, bottom of bottle still occurs cotton-shaped sometimes
Condensation product, while some sesame oil also occur muddiness under the conditions of low-temp storage, or even has cotton-shaped material to be separated out from oil
Come, so as to reduce the quality of oil, the credit of edible oil and fat is influenceed sometimes, result even in serious quality problems and cause and disappear
The query and complaint of the person of expense, sale and enterprise to sesame oil bring deleterious effect.
The content of the invention
Present invention aim at flocculate removal methods in a kind of sesame oil of offer, this method solve existing sesame oil and exist
Easily there is the problem of flocculate or precipitation when low temperature or long-time storage, and to sesame oil local flavor and qualitative effects very little.
To achieve the above object, the present invention is adopted the following technical scheme that：
Flocculation material removal methods in a kind of sesame oil, specially：Surface is added in preliminary filtered sesame crude oil to live
Property agent and be well mixed, freezing is filtered after standing.
Specifically, the surfactant is food grade sucrose fatty acid ester, and HLB value is 3 or 5；Surfactant
Addition is 0.1-the 0.5% of sesame crude oil weight.
After adding surfactant in sesame crude oil, in 50-80 DEG C of 40-80min of heating stirring its mixing can be made equal
It is even（Mixing speed is preferably 10-20r/min）, then stand 6-12h in 0-5 DEG C of freezings.
The inventive method adds lipophilic surfactant and heating stirring first in sesame crude oil, makes surfactant
It is fully contacted with the wax molecule in oil etc., while mixing speed is controlled, so as to form copolymer very well and then analysed from oil
Go out.Heating stirring needs freezing to stand after mixing, the sesame oil that freezing stood is filtered rapidly under cryogenic, filters
Temperature control is below 5 DEG C.
Traditional sesame oil processing it is main using aquation degumming, standing for a long time method come in removing or preventing sesame oil
The precipitation of flocculate, but aquation can influence the standing of the fragrance of sesame oil, long period can not well to remove sesame oil
In flocculate, low temperature or for a long time place or can become cloudy or there is flocculate to separate out.The inventive method utilizes surface-active
The colloid such as wax is easy to combine to form the characteristic of copolymer in agent and sesame oil, realizes the more sufficiently rapidly colloid such as removing wax
Thing.Using the inventive method treat sesame oil the long period, low temperature place under the conditions of it is not muddy or produce flocculate.
Compared to the prior art, beneficial effects of the present invention：
Removal methods of the present invention are simple, easy to operate, and surfactant is cheap and easy to get, also substantially reduce sesame oil
Time of repose in refining process.Using the inventive method treat sesame oil can less than 5 DEG C, placement more than one month
In the case of keep not muddy, also without flocculate separate out.
Specific embodiment
The present invention is described further by the following examples, but protection scope of the present invention not limited to this.
Embodiment 1
Flocculation material removal methods in a kind of sesame oil, specially：Addition accounts for sesame in preliminary filtered sesame crude oil
The food grade sucrose fatty acid ester of crude oil weight 0.3%（HLB value is 3）, it is well mixed in 50 DEG C of heating stirring 60min（Stir
Speed is mixed for 15r/min）, 6h then is stood in 4 DEG C of freezings, then the rapid filtration under the conditions of 4 DEG C.
Embodiment 2
Flocculation material removal methods in a kind of sesame oil, specially：Addition accounts for sesame in preliminary filtered sesame crude oil
The food grade sucrose fatty acid ester of crude oil weight 0.1%（HLB value is 5）, it is well mixed in 80 DEG C of heating stirring 40min（Stir
Speed is mixed for 10r/min）, 10h then is stood in 2 DEG C of freezings, then the rapid filtration under the conditions of 2 DEG C.
Embodiment 3
Flocculation material removal methods in a kind of sesame oil, specially：Addition accounts for sesame in preliminary filtered sesame crude oil
The food grade sucrose fatty acid ester of crude oil weight 0.5%（HLB value is 3）, it is well mixed in 60 DEG C of heating stirring 80min（Stir
Speed is mixed for 20r/min）, 12h then is stood in 3 DEG C of freezings, then the rapid filtration under the conditions of 3 DEG C.
Using the treated sesame oil of above-described embodiment below 5 DEG C of low temperature, place one month, it is not muddy, do not produce yet
Raw flocculate.
