The invention discloses a high-quality olive oil processing technology which comprises the following steps: S1, cleaning, airing and crushing fresh olive fruits to obtain olive paste; s2, transferring the olive paste into a fusion pool for fusion treatment; s3, loading the olive paste subjected to fusion treatment into a closed centrifugal machine for centrifugal treatment, taking out an upper-layer mixture, extracting oil by a physical squeezing method, collecting the oil, and filtering to remove impurities so as to obtain virgin olive oil; s4, collecting pomace olive oil floating on the upper layer from the lower precipitate olive pomace obtained by centrifugation by adopting a biological enzyme extraction method, and filtering to remove impurities; s5, mixing the squeezed olive oil with the pomace olive oil, and performing degumming, decoloration and deacidification treatment to obtain the high-quality olive oil. According to the process, the oil yield of the olive oil can be improved, unsaturated fatty acid components in the fresh olive fruits are better reserved, and the prepared olive oil is long in preservation time.
