The cellulase is beta-1, 4-glucan-4-glucan hydrolase.
The pectinase comprises protopectinase, pectin methyl ester hydrolase and pectase; the pectinase is light yellow powder.

The temperature of the dryer is about 150 ℃.
The temperature of the oil press is 60-80 ℃.
In summary, as summarized from the data in fig. 1, in the pretreatment of peanuts, when the addition amount of cellulase and the addition amount of pectinase in an enzyme solution are 5 parts and 1 part, the oil output amount changes when the temperature and the PH value of the enzyme solution are changed, the oil output amount gradually increases with the increase of the temperature, the oil output amount tends to be stable at 50-65 ℃, but when the oil output amount is stable and is more than or equal to 70 ℃, the oil output amount begins to decrease; on the other hand, the oil output quantity is gradually increased along with the continuous increase of the pH value of the solution at the same temperature, and the oil output quantity reaches the highest value when the pH value reaches about 4.5; the data in the table show that the oil yield reaches the maximum value when the solution pH is maintained at 4.5 and the temperature is in the range of 50-65 ℃.
From the data in examples 1,4 and 5, the oil yield is gradually increased when the adding amount of the cellulase and the pectinase is gradually increased, and the oil yield of the peanuts is the highest when 8 parts of the cellulase and 4 parts of the pectinase are added, which shows that the effect of the added amount on the peanut cell walls cannot be optimal at the moment.
As shown in FIG. 3, in examples 5 and 6, the enzyme treatment time of the peanut granules was changed before oil extraction to obtain different oil extraction rates, which indicates that when the enzyme treatment time of the peanut granules is too long, the cell walls are damaged excessively, so that the unsaturated fatty acid substances are lost during washing and baking; therefore, the enzyme treatment time reaches an appropriate state when being 3-5 min.
The data in fig. 4 summarize that when the treatment step of activated carbon and ozone is not added in the treatment of the crude peanut oil, the obtained finished oil has a heavy peculiar smell, and the impurity content in the finished oil is high, which affects some qualities; when bad grains in the peanut raw material are not removed, the aflatoxin content in the finished oil is obviously over standard, and when the bad grains are removed and no activated carbon or ozone treatment is carried out, the aflatoxin content is still high, and the health is influenced after long-term use; on the other hand, the transparency, acid value and phospholipid content all tend to be stable.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.

(5) crushing and enzyme treatment: adding peanuts into a crusher for crushing treatment, and sieving to ensure that the diameter of the peanut particles is less than 3 mm; dissolving 5-10 parts of cellulase and 1-5 parts of pectinase in water to prepare a mixed enzyme solution, and adjusting the pH value of the solution at 10-80 ℃; adding appropriate amount of enzyme solution into the peanut granules, stirring, mixing well, contacting the peanut granules with the enzyme solution for 3-5min, filtering, and washing for multiple times to obtain peanut granules;
(6) baking: conveying the peanut particles obtained in the step 4 to a dryer, and drying until the water content in the peanut particles is lower than 5%;
(7) blank rolling and oil pressing: crushing peanut particles into slices, adding the sliced peanuts into an oil press, and pressing oil to obtain crude oil; mixing the filter cake with other substances to prepare animal feed;
(8) deodorizing: putting a proper amount of active carbon into the crude oil, standing for a period of time to remove the heavier peculiar smell in the crude oil, filtering the active carbon, introducing a small amount of ozone into the crude oil, and further oxidizing the micromolecular organic matters generating the peculiar smell in the crude oil;
(9) refining: filtering the crude oil with double-layer filter cloth to obtain coarse-filtered peanut oil; carrying out primary fine filtration on the coarse filtered peanut oil to obtain primary fine filtered peanut oil; and performing secondary fine filtration on the primary fine-filtered peanut oil to obtain finished peanut oil.
2. The virgin peanut oil of claim 1, and processes for producing the same, wherein: the cellulase is beta-1, 4-glucan-4-glucan hydrolase.
3. The virgin peanut oil of claim 1, and processes for producing the same, wherein: the pectinase comprises protopectinase, pectin methyl ester hydrolase and pectase; the pectinase is light yellow powder.
4. The virgin peanut oil of claim 1, and processes for producing the same, wherein: the ozone removes harmful moulds such as aflatoxin and the like in the crude oil.
5. The virgin peanut oil of claim 1, and processes for producing the same, wherein: the temperature of the dryer is about 150 ℃.
6. The virgin peanut oil of claim 1, and processes for producing the same, wherein: the temperature of the oil press is 60-80 ℃.
