Specific embodiment
A kind of method that aqua method extracts melon seeds in August oil, it includes:
Melon seeds in August is placed in 55 DEG C of drying box dry 48 hours by step 1, is removed impurity, is crushed with pulverizer,
Smashed Stauntonia latifolia powder of seeds is placed at 4 DEG C and is saved backup；
The method for obtaining Stauntonia latifolia powder of seeds is crushed with pulverizer described in step 1 are as follows: is crushed using high speed Universal pulverizer
After August melon seeds, Stauntonia latifolia powder of seeds is crossed into 40 meshes.
The high speed Universal pulverizer is the DFT-200 of Shanghai Lei Gu Instrument Ltd.；Drying box is electric heating constant temperature drum
Wind drying box, Shanghai Hui Tai instrument manufacturing Co., Ltd DHG-9030A.
Stauntonia latifolia powder of seeds is placed in glass spinner flask by step 2, uses the thermostat water bath with magnetic stirring function
Continuous stirring makes the fuel-displaced formation leaching liquor of Stauntonia latifolia powder of seeds；
Thermostat water bath uses the SHJ-6AB of Changzhou Jintan beneficial friend Instrument Ltd..
Step 2 is obtained leaching liquor and is put into centrifuge tube by step 3, is centrifugated 20min by centrifuge；In centrifugal force
Under effect, grease is split into upper layer, and lower layer is emulsion layer；
Centrifuge uses high speed freezing centrifuge；The Sigma 3-18ks of Beijing Five continents east development in science and technology Co., Ltd.
Step 4 draws upper layer grease, is denoted as edible vegetable oil I；
Step 5, be demulsified method using freeze-thaw, and emulsification is placed in the environment of -20 DEG C and freezes 12h, 80 DEG C of defrostings
Afterwards by centrifuge separation demulsification, upper layer edible vegetable oil is drawn again；It is denoted as edible vegetable oil II；
Merge edible vegetable oil twice to weigh, August, melon seeds oil yield calculated as follows:
Wherein, total oil quality=material quality × raw material crude fat content of raw material.
Constantly being stirred described in step 2 using the thermostat water bath with magnetic stirring function keeps Stauntonia latifolia powder of seeds fuel-displaced
When forming leaching liquor, the ratio of Stauntonia latifolia powder of seeds and water are as follows: 1:5g/mL.
All determining solid-liquid ratios of the present invention are 1:5；It is because finding melon seeds in August oil extract rate with the increasing of liquid-to-solid ratio
Big is in downward trend after first rising.When liquid-to-solid ratio progressively increases to 5:1 from 2:1, recovery rate progressively increases to maximum value
Oil yield under (64.59% ± 0.63), with other levels has significant difference (P < 0.05).When liquid material is smaller, mention
Take rate not high, it may be possible to which, because the amount of extractant is less, system is excessively sticky, and intracellular grease is not easy from albumen emulsus system
It is middle replaced water so that extracting incomplete.And liquid material ratio it is excessively high when, oil with screenings emulsification degree increasing is not easy from, influence
Fuel-displaced effect, recovery rate decline, therefore, solid-liquid ratio the most suitable is 1:5g/mL.
When constantly stirring thermostat water bath using the thermostat water bath with magnetic stirring function described in step 2, extract
Temperature is 65 DEG C.
Why Extracting temperature is selected in 65 DEG C by the present invention；It is because when Extracting temperature is increased to 65 DEG C from 35 DEG C eight
Month melon seeds oil extract rate is in rising trend, when extraction temperature is 65 DEG C, oil yield reach maximum value (67.93% ±
0.91), have with the oil yield under other levels significant difference (P < 0.05).This is because as the temperature rises, molecule
Movement velocity is accelerated, and grease is easier to be transferred to out from cell, accelerates dissolution of the aqueous solution to melon seeds oil in August.Work as extraction
When temperature is more than 65 DEG C, oil yield is declined, this may be because temperature raising causes the solubility of protein to increase, to three
The adsorption rate of leaf akebia seed oil increases so that the grease in August melon seeds be not easy by it is water-soluble go out caused by.It is most suitable for when therefore extracting
Extracting temperature be 65 DEG C.
Constantly being stirred described in step 2 using the thermostat water bath with magnetic stirring function keeps Stauntonia latifolia powder of seeds fuel-displaced
When forming leaching liquor, extraction time is 1 hour.
Melon seeds in August oil extract rate of the invention reduces afterwards as the extension of extraction time first increases, and constant temperature stirs 2h, so that
Oil yield reaches maximum value (67.96% ± 0.68), has significant difference (P < 0.05) with the oil yield under other levels.
Heating stirring can preferably destroy melon seeds cell in August, allow the water to replace the grease being wrapped in homogenate, grease can be maximum
Limit it is released.Extraction time is more than 1h, and recovery rate is on a declining curve, this is because the time is longer, will cause moisture
Evaporation is excessive, so that slurries are more and more sticky, extraction effect is bad, it is contemplated that the efficiency of actual production, optimum extraction eight
The time of the melon seeds oil moon is 1h.
20min, the centrifuge speed are as follows: 5500r/min are centrifugated by centrifuge described in step 3.
With the increase of centrifugal force, Akebia trifoliata seed oil yield is gradually increasing.When centrifugal force increases, it is wrapped in slurries
Grease can be easier to be separated, the emulsion layer that centrifugal force more ambassador must be distributed in top layer is thinner, has certain broken
Newborn effect, recovery rate can be higher.Therefore, centrifuge RPMs maximum is selected in 5500r/min by the present invention.
The present invention extracts melon seeds in August oil using aqua method, on the basis of experiment of single factor, it is determined that natural pure water is
Extraction solvent, centrifugal rotational speed 5500r/min have selected to extract temperature to the liquid-to-solid ratio that August, melon seeds oil extract rate was affected
Degree and these three factors of extraction time to melon seeds oil extract rate influence size in August successively are as follows: extraction time > Extracting temperature
> liquid-to-solid ratio, and extraction time, Extracting temperature and solid-liquid ratio make a significant impact melon seeds oil extract rate in August.
By obtaining the optimised process item of melon seeds grease agent method in August extraction after experiment of single factor and response surface analysis optimization
Part are as follows: Stauntonia latifolia powder of seeds crosses 40 meshes, and with natural Aqua pure extract solvent, liquid-to-solid ratio 5:1, Extracting temperature is 65 DEG C, extracts
Under conditions of time 1.2h, August melon seeds oil recovery rate up to 68.85 ± 0.75%.Realization proposes the maximum of melon seeds oil in August
It takes.Reduce waste.
