Problems solved by technology

[0003] The olive oil processing technology in the prior art mainly has the following problems: 1, the existing olive oil processing technology has a low oil yield, and the olive oil quality obtained is relatively poor; 2, chemical substances are usually added in the existing olive oil processing technology, And it needs to be treated at high temperature for a long time, and many bioactive components in olive oil are temperature-sensitive substances. High temperature treatment causes a large amount of degradation of active components, which greatly reduces the nutritional value of olive oil

Abstract

The invention discloses a high-quality olive oil processing technology which comprises the following steps: S1, selecting mature olive, cleaning, airing, peeling, shelling, and grinding into paste to obtain olive kernel pulp; S2, soaking the olive kernel pulp in a mixed solution composed of a green tea concentrated solution and a demulsifier, and performing ultrasonic treatment to obtain pretreated olive kernel pulp; S3, treating in microwave vacuum equipment, performing cold pressing through a hydraulic cold pressing machine, and performing carbon dioxide supercritical extraction to obtain virgin olive oil; S4, cooling the virgin olive oil, stirring and crystallizing, and removing uncrystallized and solidified olive oil on the upper layer to obtain refined olive oil; S5, adding zingiberone alcohol and avocado oil into the refined olive oil, carrying out ultrasonic oscillation and centrifugal separation, and collecting an oil material; and S6, carrying out vacuum filtration on the oil material. The processing technology is simple, safe and environment-friendly, the oil yield is increased, addition of chemical substances and long-time high-temperature treatment are avoided, the nutritional value in the olive oil is effectively reserved, and the anisidine value of the olive oil is reduced.

Description

technical field [0001] The invention relates to the technical field of olive oil processing, in particular to a high-quality olive oil processing technology. Background technique [0002] Olive oil is the oil directly extracted from the olive fruit by cold treatment, and the nutrients in it have not been destroyed, so it is considered to be the most suitable natural oil for the human body. For a long time, olive oil has the beauty and title of "vegetable oil queen", and it is also called "liquid gold" in the West. Olive oil is rich in monounsaturated fatty acid - oleic acid, which can not only provide heat energy to the human body, but also effectively prevent excess cholesterol in the body, prevent high blood pressure, coronary heart disease and other diseases. [0003] The olive oil processing technology in the prior art mainly has the following problems: 1, the existing olive oil processing technology has a low oil yield, and the olive oil quality obtained is relatively ...
