Description
Technical field
The present invention relates to a kind of production technology of edible oil, more particularly to a kind of production technology of sunflower seeds edible oil.
Background technology
At present, in the prior art the preparation technology of sunflower oil exist it is many need solve the problem of, for example：
1) in order to ensure that process conditions are harsh in produced sunflower oil quality, refinery practice, once process conditions are not
Meet, obtained sunflower oil quality can be caused to reduce, for example：Prior art is deodorized using single column structure, during deodorization heating
High-pressure boiler control it is improper so that the excessive high temperature of deodorization, then causing the trans-fatty acid numerical value of obtained sunflower oil is
4~5 times of normal value；In another example：Deodorization equipment or finished product storage tank equipment use carbon steel material, and grease cooling is improper, causes to add
Plus unnecessary antioxidant, cause grease to preserve quality not good.
2) shortcoming of plate column single column：Flexible modulation can not be accomplished in the control of deodorization time.It is deodorized for a long time stagnant
Stay, easily cause neutral oil micro hydrolysis in deodorizing tower, free fatty acid content is gone up, it is also possible to produce new grease and gather
Compound, more seriously causes the gradually increase of the content of trans fatty acids of deodorised oil.
3) shortcoming of material filling type single column：Major function is physical deacidification, and deodorising effect is simultaneously not so good as tray column significantly, by
It is very thin in the liquid film of grease, treat that deodorised oil holdup time in tower is short, the thermal sensitivity pigment in bleached oil can not be decomposed completely, heat
Decolorizing effect is good not as plate column effect, and deacidification effect is not also obvious.
4) sunflower seeds crude oil is refined into during sunflower oil, and refining is operated by rule of thumb by operator more, to improve cigarette
Point, causes grease in excessive temperature, crosses under high vacuum, produce trans-fatty acid, do harm to huamn body on the contrary.In addition, sunflower
Nutritional ingredient such as vitamin E in seed crude oil can excessively be deviate under excessive production and processing.
Because of this it may be desirable to obtain a kind of production technology, by controlling each Parameter Conditions in process conditions, improve what is obtained
The quality of sunflower oil.The oil smoke amount produced when the sunflower oil that the production technology is obtained is through high-temperature heating is significantly less than existing
The sunflower oil that technology is produced.In addition, nutritional ingredient such as vitamin E contained by the sunflower oil that the production technology is obtained
Content is higher than the sunflower oil that prior art is produced, and the content of trans-fatty acid is significantly reduced.
The content of the invention
It is an object of the invention to provide a kind of production technology of low oil smoke sunflower oil, by process conditions especially
The improvement of deodorizing technology, substantially increases the quality of obtained sunflower oil.The sunflower seeds obtained is produced by the production technology
The oil smoke amount produced when oil is through high-temperature heating is low, and contained nutritional ingredient is high in sunflower oil.Content of trans fatty acids is few.
To achieve these goals, the present invention proposes a kind of production technology of low oil smoke sunflower oil, including following step
