High-quality olive oil processing and waste pomace recycling method

Abstract

The invention discloses a high-quality olive oil processing and waste pomace recycling method. The method comprises the following steps: designing a horizontal ultrasonic-assisted two-phase spiral separator, cleaning and crushing fresh olives, entering an ultrasonic wall breaker for wall breaking, stirring and fusing, and reducing the fusion temperature from 30-40 DEG C to 10-20 DEG C; centrifuging to separate crude oil and water-containing pomace by adopting the two-phase spiral separator, settling the crude oil in a refrigeration house, performing filter pressing with active diatomite, and filtering by a 5-50nm ceramic membrane so as to obtain polyphenol-enriched high-quality special grade virgin olive oil; performing electroosmotic dewatering and compounding on the waste pomace to prepare a bio-fertilizer, performing biological fermentation on wastewater, and preparing fruit wine from the filtrate by virtue of 10-100nm ceramic membrane and pasteurization; and merging all the wastewater in the production process, filtering by a three-level series ceramic membrane of 10-100 microns, performing resin enrichment so as to obtain olive polyphenol extract having the total polyphenol content of more than or equal to 90%, and separating to prepare oleuropein, hydroxytyrosol, oleanolic acid, ursolic acid, maslinic acid, verbascoside, galuteolin and other polyphenol monomer compounds by adopting molecular imprinting directed enrichment and high-speed countercurrent chromatography coupling technologies.

Description

technical field

[0001] The invention relates to the comprehensive processing of woody oil forest products and its application in the fields of food, biology and medicine, in particular to the technology of processing high-quality olive oil and recycling waste pomace. Background technique

[0002] Olive (Olea europaea L.), an evergreen tree belonging to Oleaceae Oleaceae, is one of the world's famous woody oil tree species. Since the 1960s, Gansu, Sichuan, Yunnan and other places in my country have gradually begun to introduce olives. Longnan City, Gansu Province is one of the largest planting bases of olives in my country. Olive oil is developing rapidly in my country, the planting area is increasing at a rate of 100,000 mu per year, the planting base is more than 1 million mu, and the industrial chain is more than 10 billion yuan. However, my country's olive industry has problems such as large planting area, miscellaneous varieties, few suitable areas, and low fruiting rat...
