Description
Technical field
The invention belongs to processing engineering technology field, and in particular to a kind of processing method for promoting camellia seed oil generation.
Background technology
Oil tea（Camellia oleifera Abel.）It is the woody oil tree species that China is distinctive, main.Camellia seed oil
It is a kind of faint yellow or brown clarification shape liquid, and there is the peat-reek of tea oil.Camellia seed oil mainly by oleic acid, linoleic acid,
The unrighted acid such as palmitic acid and leukotrienes forms, with universally acknowledged quality plant grease --- the composition composition of olive oil
It is closely similar, and its unsaturated fatty acid content is higher than olive oil, the physicochemical characteristics of camellia seed oil also with olive oil
It is closely similar.The camellia oleifera fruit oil content of fresh harvesting is relatively low, and the forming process of grease occurs mainly in the place after camellia oleifera fruit harvesting
Reason process.At present, conventional processing method has artificial drying, natural drying etc., but fails to the raising camellia oleifera fruit compared with limits
Oil yield, it could not greatly utilize camellia oleifera fruit resource.Such as Chinese patent 201110000925.2（Application number）Disclose one
Kind method for pressing tea seeds at normal temperature, tea seed, shelling, tempering water, normal temperature squeezing, coarse filtration, refined filtration etc. are selected by cleaning and walked
Suddenly, camellia seed oil is obtained, regulation moisture is quenched with quenched pot by drying, oil yield 23-25%.Chinese patent
201210386643.5（Application number）Disclose a kind of production method of pure physics original odor type camellia seed oil, including raw material selection,
The steps such as raw material stoving, tea seed are peeled off, cold pressing, aquation degumming, middle temperature is dried, freezing and crystallizing, secondary filter, adjust moisture
Mode uses hot-air seasoning.Therefore, a kind of processing method for promoting camellia seed oil generation is invented, excavation that can be more deep is oily
The value of tea resource, production cost is reduced, further improve the economic benefit of camellia oleiferaindustry.
The content of the invention
For above-mentioned problems of the prior art, the present invention provides a kind of processing side for promoting camellia seed oil generation
Method, after being handled with this method, the oil yield of tea seed is higher than conventional treatment method by 5~10%.
Technical scheme is as follows：
1. a kind of processing method for promoting camellia seed oil generation, it is characterised in that comprise the following steps：
（1）Fresh fruit is plucked：The full fresh camellia oleifera fruit of artificial harvesting ripe；
（2）After-ripening increases oil：Camellia oleifera fruit is laid in Aging storage 24-48 h on drier in the interior of ventilation；
（3）Refrigeration increases oil：Camellia oleifera fruit is subjected to rapidly gradient refrigeration, that is, be initially positioned at temperature be 6~15 DEG C, relative humidity 60
4~50 h are stored under conditions of~75%；Be subsequently placed in temperature be 0~4 DEG C, relative humidity store 3 under conditions of being 50~55%
~25 h；Temperature is placed in again to be -10~-5 DEG C, store 2~15 h under conditions of relative humidity is 40~45%；Finally it is placed in temperature
Spend for -20~-15 DEG C, relative humidity be 30~35% under the conditions of store 1~10 h；
（4）Dry：Camellia oleifera fruit after chilling treatment is placed in 20~90 DEG C of baking ovens, it is 25~30% to dry to moisture, so
It is 5~15% that camellia oleifera fruit is carried out into vacuum freeze drying to camellia oleifera fruit moisture rapidly afterwards；
（5）Shelling：Camellia oleifera fruit is shelled, obtains camellia seed kernel and oil-tea camellia husks；
（6）Squeezing：By camellia seed kernel and oil-tea camellia husks according to 85~95%：5~15% mass ratio mixing, normal temperature is carried out after crushing
Squeeze, camellia seed oil is obtained after vacuum filtration.
Preferably, step（2）Described drier is that mass ratio is 6~9：1~3：0.1~0.5 quick lime, montmorillonite
The mixture of powder and starch.
Preferably, step（2）The mass ratio of described drier and the camellia oleifera fruit is 1：100~200.
Preferably, step（2）There is interlayer between described drier and described camellia oleifera fruit, the interlayer is gauze, inhaled
Any one of water paper, straw.
Preferably, step（3）It is that camellia oleifera fruit is carried out rapidly into gradient refrigeration that described refrigeration, which increases oil, and being initially positioned at temperature is
10 DEG C, relative humidity be 65% under conditions of store 40 h；It is subsequently placed in that temperature is 4 DEG C, relative humidity stores under conditions of being 50%
Hide 12 h；Be placed in again temperature be -8 DEG C, relative humidity 6 h are stored under conditions of being 45%；Finally be placed in temperature for -20 DEG C, it is relative
Humidity stores 2 h under the conditions of being 30%.
Preferably, step（4）Its condition of described vacuum freeze drying is temperature -10~-20 DEG C, and vacuum is -0.08
~-0.09 MPa.
Preferably, step（5）Described shelling, its husking yield >=99%.
Preferably, step（6）Described camellia seed kernel and oil-tea camellia husks are according to 92%：8% mass ratio mixing.
Preferably, step（6）Described crushing control camellia seed kernel and the grain of oil-tea camellia husks mixture are through being 2~5 mm.
The present invention promotes camellia seed oil to generate and improve the principle of oil yield：
（1）After-ripening increases in oily step, and the moisture in the presence of drier of the fresh camellia oleifera fruit after harvesting reduces, from green oil
Tea fruit enters the after-ripening stage of camellia oleifera fruit, i.e., the intermediate product of classes of compounds can synthesize final product rapidly in camellia oleifera fruit, oil
The intermediate product of fat can also form aliphatic acid and glycerine, and then the content of Synthetic Oil increase camellia seed oil；（2）Refrigeration increases oil step
In rapid, in gradient cold storage procedure, camellia oleifera fruit is at 6~15 DEG C, due to less than growth temperature, its energy storage of the grease type of unit mass
Maximum, therefore the ergastic substances such as glucose in camellia oleifera fruit and protein can change into grease type by biochemical reaction, make cell
The energy maintained up to while minimum quality is lost, at 0~4 DEG C, cell progresses into resting state, all kinds of physiology lifes
The rate reduction of change activity, the loss of cellular energy is reduced, by the low-temperature treatment in above two stages, camellia oleifera fruit is intracellular
Grease reserves reach maximum, and cellular activity drops to relatively low amount, and then process -10~-5 DEG C freeze, and cellular activity stops substantially,
It is cooled to -20~-15 DEG C again after cell adapted cryogenic temperature, the cell of the overwhelming majority can be made to stop physiological activity, now may be used
Ensure that the grease of camellia oleifera fruit is no longer consumed, and high value nutriment therein such as vitamin E, bata-carotene, squalene and β
Sitosterol etc. can preserve very well；（3）In drying steps, oven drying can reduce moisture, can also condense grease, change
Kind oil quality, then quick freeze drying can protect nutriment not to be destroyed under low-temperature condition, avoid acid number and mistake
Oxidation number rise influences oil quality；（4）Squeeze in step, camellia seed kernel and oil-tea camellia husks mixing and crushing, equivalent in oil
Increase extrudate and squish area in tea seed kernel, improve the Milling Efficiencty and oil yield of camellia seed kernel.
Beneficial effects of the present invention are：
1st, the present invention promotes the significant effect of tea-seed oil generation, and oil yield is 42.4~43.7%, more fuel-displaced than Conventional processing methods
Rate is high by 10~15%.
2nd, camellia seed oil of the invention is best in quality, and more than 90%, its mid-oleic is unsaturated fatty acid content
81.49~83.25%, linoleic acid content 8.46~9.03%, saturated fatty acid content is 7.06~9.26%.
