Method for preparing blend oil and cold-pressing and extracting peony seed oil

The invention relates to a method for preparing blend oil and cold-pressing and extracting peony seed oil. The method comprises the following steps: collecting and dehulling seeds, cold-pressing and secondary-filtering, producing and filling the blend oil. The invention has a simple oil-extracting process and reduces the loss of active components in oil-extracting process. Cold pressing temperature is low so that phospholipid, pigment, and the like hardly enter oil, and the cold pressing oil has lighter color and lower phospholipid content and can achieve a new international four class oil standard only by mechanical filtration instead of any chemical refining. Cold pressing rap oil has high nutritive and healthcare values because thermosensitive alpha-tocopherol and phytosterols are fully remained, active protein and other active components in peony seeds are remained so as to creates advantages for further developing new purposes of the seeds; no refining sewage is discharged in thecold pressing production
