High-quality olive oil processing technology

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of vegetable oil processing, in particular to a high-quality olive oil processing technology. Background technique [0002] Olive oil is the oil extracted and separated from fresh olive fruit. The content of unsaturated fatty acid in olive oil is 82%-87%. Natural nutrients such as squalene and sterols have an absorption rate of 93.40% and have a variety of health effects on the human body, especially for preventing and reducing cardiovascular diseases and promoting the development of children's bones and nervous systems. Therefore, , olive oil is more and more favored by people, and the market demand is increasing. [0003] At present, olive oil processing technology is divided into physical method and chemical method. Chemical method needs to use organic solvent to soak olive oil. Large, and the solvent chemical residue is high, the quality of the oil produced is poor; the processing process of physical m...

Problems solved by technology

[0003] At present, olive oil processing technology is divided into physical method and chemical method. Chemical method needs to use organic solvent to soak olive oil. Large, and the solvent chemical residue is high, the quality of the oil produced is poor; the processing process of physical methods such as figure 1 As shown, the fresh olive fruit is washed, ground, and then pressed, the mixture of olive oil and water is squeezed out, the olive pomace is separated, and the mixture of olive oil and water is separated to obtain olive oil. The olive pomace produced is usually directly discarded, but due to the high oil content in the olive pomace, the waste rate of olive oil processed by physical methods is high, and the obtained olive oil has high acidity and is not resistant to storage
