Description
Technical field
The invention belongs to the processing method of walnut oil, is related to the processing method of stone mill walnut oil, is specially substituted with stone mill
The new machining method of squeezing.
Background technology
Walnut oil is that preferably advanced edible cooking oil, the Conventional processing methods of walnut oil are in people's daily life：Will
(not removing the peel) walnut kernel obtains walnut oil by squeezing, refining, decolouring, deodorization, filtering.
Such as a kind of processing method of walnut oil in the prior art, concretely comprise the following steps：（1）, walnut kernel is placed in frying pan, fry
10-20 minutes processed, temperature are 120-140 DEG C, obtain steaming and fry thing；（2）, by steam fry thing crush；（3）, again will be broken walnut kernel
Put oil press into be squeezed, produce crude oil；（4）, atomization decontamination：Crude oil is squeezed into atomization pot, heated with steam, by oil
When being heated to 75-80 DEG C, 75-80 DEG C of water is added, the addition of water is the 1-2% of quality of crude oil, and is stirred 0.5-1
Hour, then precipitation filtering 2-3 hours, the impurity in oil is excluded from the lower outlet of atomization pot；（5）, degumming：By what is be atomized
Oil squeezes into glue kettle, and oil is heated into 75-80 DEG C, stirred 0.5-1 hours, precipitation filtering, treats that the temperature of oil is down to 60-65 DEG C
When, the colloid precipitated in oil is emitted from the slag-drip opening of glue kettle；（6）, by the oil after degumming, carry out conventional decolouring,
After deodorization, oil is delivered to macromolecular filtering equipment, oil temperature is filtered when being maintained at 60-65 DEG C, got product；Wherein, walk
Suddenly（4）、（5）Belong to refinement step.
In above-mentioned processing method, walnut kernel is not removed the peel, and frying temperature is high, and the easy high temperature of walnut kernel burns, in subsequent step
Crude oil is obtained by physical squeezing, easy-clear is not thorough for the bitter taste of walnut oil, influences mouthfeel, oil yield 48-50%；Walnut
Oil quality is not high, is decolourized by activated carbon or carclazyte to remove BaP, BaP is easily exceeded；In refinement step, add
Food additives, the natural nutritive value of walnut oil and taste are influenceed, and production cost is high.
Also one kind is water substitution, i.e., the method " with water generation oil ", using the non-oil component in oil plant to oil and water " affinity "
Difference, while using water, the difference of oil density, go out grease with physical method for separation, its process route be by walnut kernel impurity elimination,
Cook, defibrination, then be watered and stir oil（Coolant-temperature gage is added to be less than 50 DEG C）, vibration point oil, finally carry out quiescent setting, packing, obtain into
Savor walnut oil；Its technique is simple, safe and reliable and economical, but is watered and stirs amount of water in oil and be difficult to control, there is oil yield it is low,
The shortcomings that separation is more difficult, oxidizable.
The content of the invention
In order to improve the quality of walnut oil, the bitter taste of walnut oil is thoroughly removed, keeps improving walnut oil to a greater extent
Natural nutritional ingredient, improve oil yield, the processing method that the present invention proposes stone mill walnut oil.
The inventive concept of the present invention：Using barking walnut kernel, the baking temperature of walnut kernel is reduced, avoids bitter taste；Use stone
Mill substitutes squeezing, keeps improving the natural nutritive value of walnut oil to a greater extent, the walnut oil New Product Definition of the present invention
For：Stone mill walnut oil.
To achieve the goal, the technical solution adopted by the present invention is as follows：The processing method of stone mill walnut oil, is concretely comprised the following steps：
（1）Baking：Barking walnut kernel is put into baking box and toasted, 80-90 DEG C of baking temperature, baking time 25-45 minutes；
（2）Stone mill is ground：Barking walnut kernel after will be baked is poured into electric millstone mill funnel, is started electric millstone mill, is fallen
Skin walnut kernel, whereabouts flow velocity is adjusted with the rotation of stone mill, it is 1-2 centimetres to keep the material thickness on stone mill, will remove the peel walnut
Benevolence wears into pasty state, and granularity is 100-200 mesh, flows into slot grinding, obtains walnut dew；
（3）It is watered and stirs oil：Walnut dew is added in vibration pot, 95-100 DEG C of 0.8-1 times of quality is added by the quality of walnut dew
Boiling water, carry out high temperature sterilization；After walnut dew mixes with water, temperature is down to 70-80 DEG C, mixes -1.5 hours 50 minutes, turns
Speed control carries out vibration point oil in 8-10 circles/minute, vibration pot, residue is separated with oil, 50-60 DEG C of keeping temperature, separation
Minute time 35-50, upper strata walnut lubricant is taken, obtains crude oil；
（4）Crude oil processing
（4.1）Initial filter：Crude oil is poured into crude oil groove, the filter of 200-300 mesh is delivered directly to by the pipeline connected, is entered
The primary separation of row, and it is transported to primary oil storage tank；
（4.2）Refined filtration：The crude oil of primary filter is transported to the strainer of 300-400 mesh from primary oil storage tank by pipeline, controlled
15-20 DEG C of liquefaction temperature, obtain stone mill walnut oil finished product；
（4.3）After stone mill walnut oil finished product is sampled detection, oil storage tank is transported to, in 8-20 DEG C of storage at ambient temperatures.
Beneficial effect：The present invention is toasted using barking walnut kernel with 80-90 DEG C of unit temperature, avoids damage to walnut kernel
Natural nutrient component；Stone mill substitutes squeezing of the prior art, and stone mill grinding process will not destroy the feature in walnut kernel
Natural nutrient component, and the granularity of walnut is controlled, amount of water, water temperature and mixing time are limited in oil being watered to stir, is fully ensured that
With the process of water generation oil, oil yield is improved, oil yield reaches 55-62%；Dephosphorization in existing technology, degumming and refining work are not needed
Sequence, food additives are not added, ensure that natural nutrient component and the taste of walnut oil, eliminate bitter taste, the benzene in oil
And pyrene is not exceeded, BaP is 0.5-1 mgs/kg；Obtained stone mill walnut oil bright, unrighted acid total amount reach
To more than 90%, wherein leukotrienes 10-15%, oleic acid 17-20%, linoleic acid 55-63%, leukotrienes and linoleic ratio are close to 1:
It is the golden ratio of world health organisation recommendations edible oil aliphatic acid composition between 4-6.
