Abstract：Taking the extraction rate of peony seed oil as the index,steam blasting-assisted cold pressing technology was adopted to optimize the extraction process of peony seed oil through single factor and response surface experiments.On this basis,the effect of steam explosion on the fatty acid composition was analyzed.The results showed that the optimal extraction process of peony seed oil was steam explosion time of 70 s,explosion pressure of 1.2 MPa,and cavity material ratio of 2∶1(mL/mL).Under these conditions,the extraction rate of peony seed oil was 31.03％,and the extraction rate of peony seed oil with steam explosion pretreatment increased by 12.644％higher than that without steam explosion.The fatty acid analysis results showed that the content of oleic acid,stearic acid,and arachidic acid in the peony seed oil extracted by steam explosion-assisted cold pressing technology higher than those in the non-steam explosion product.This study provided a theoretical basis for the efficient extraction and quality control of peony seed oil.
