Abstract

The invention discloses a preparation process for fragrant vegetable seed oil, relating to the technical field of edible grease processing. The preparation process is characterized by comprising the following process steps of: (1) selecting clean fragrant vegetable seeds without impurities, feeding the fragrant vegetable seeds into a crusher for crushing, and spraying the obtained fragrant vegetable seed powder with water to obtain an oil-water mixed solution; (2) roughly filtering the oil-water mixed solution in the step (1) by using a plug with 24-26 meshes and then finely filtering by using a plug with 80-100 meshes; (3) centrifuging the finely-filtered solution in the step (2) at the high speed of 6000r/min and then standing and demixing to remove water and the impurities; and (4) carrying out reduced-pressured filtering on the solution obtained in the step (3) to remove suspending impurities and further obtain the fragrant vegetable seed oil. The preparation process disclosed by the invention is simple and practical and is short in extraction time; and the extracted fragrant vegetable seed oil has the advantages of pure flavor, bright color and luster, no precipitation, long preservation period and low possibility of flavor reversion.

Description

The preparation technology of caraway seeds oil

Technical field

The present invention relates to the food oils processing technique field, be specifically related to a kind of preparation technology of caraway seeds oil.

Background technology

As everyone knows, the rapeseed oil of traditional workshop-based production is vegetable seed to be sent into the marmite frying enter the oil press zhai squeezing after good.The rapeseed oil grease colloid that this method is produced exceeds standard, and oil colours is dark.In order to address this problem, people adopt the aquation method directly to precipitate usually, and the workshop-based producer does not have purification apparatus usually, so that the oil of being produced can't reach the fixed moisture standards of secondary fuel oil meter, cause the grease quality guaranteed period short, have in addition phenomenon once, fouling in two months appears.The tradition rapeseed oil another kind of working method be, with vegetable seed with steam heating after, put into 202 preformers and squeeze.Though this method can form in batches, the rapeseed oil colloid severe overweight that is processed needs through eating behind hydration degum, alkali cleaning, washing, the dehydration procedure.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of features simple and practical process, the preparation technology of the caraway seeds oil that oil yield is high.

Technical problem to be solved by this invention realizes by the following technical solutions,

The preparation technology of caraway seeds oil is characterized in that: its processing step is as follows,

1., select clean pure caraway seeds for use, caraway seeds is put in the pulverizer is pulverized, again the vegetable seed powder water that obtains is sprayed, thereby obtains oil-water mixture;

2., the oil-water mixture of step in 1. carried out coarse filtration with 24～26 purpose stoppers, carry out fine filtering with 80～100 purpose stoppers more afterwards;

3., with step 2. in solution behind the fine filtering carry out high speed centrifugation (6000r/min), standing demix removes and anhydrates and impurity then;

4., with step 3. in the solution of gained carry out filtration under diminished pressure and remove suspended impurity, thereby obtain caraway seeds oil.

The invention has the beneficial effects as follows: features simple and practical process of the present invention, extraction time is short, extraction rapeseed oil fragrance pure, color and luster is vivid, does not have precipitation, preservation period limit for length is difficult for spoiled.

Embodiment

For technique means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.

The preparation technology of caraway seeds oil, its processing step is as follows,

1., select clean pure caraway seeds for use, caraway seeds is put in the pulverizer is pulverized, again the vegetable seed powder water that obtains is sprayed, thereby obtains oil-water mixture;

2., the oil-water mixture of step in 1. carried out coarse filtration with 24～26 purpose stoppers, carry out fine filtering with 80～100 purpose stoppers more afterwards;

3., with step 2. in solution behind the fine filtering carry out high speed centrifugation (6000r/min), standing demix removes and anhydrates and impurity then;

4., with step 3. in the solution of gained carry out filtration under diminished pressure and remove suspended impurity, thereby obtain caraway seeds oil.

More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
