A method for preparing field muskmelon oil includes the following steps: S1, removing foreign matter, including: removing the foreign matter in field muskmelon seeds； S2, low-temperature pressing, including: performing the low-temperature pressing on the field muskmelon seeds after removing the foreign matter in step S1 to obtain an oil residue mixture； S3, filtering and removing impurities: filtering the oil residue mixture obtained by the low-temperature pressing in step S2 to remove the impurities to obtain a primary oil； and S4, centrifugal separation, including: centrifugally separating the primary oil obtained by filtering and removing impurities in step S3 to obtain the field muskmelon oil. The new method avoids using high-temperatures resulting in optimal yield of nutritional content and no harmful byproducts.
