Problems solved by technology

The market is more willing to use the water enzymatic method to extract olive oil products, there are no risks in eating, and the quality of olive oil is higher
However, a large amount of industrial wastewater will be produced in the process of enzymatic olive oil production. Because the wastewater contains a lot of nutrients such as protein, sugar and oleuropein, traditional wastewater treatment methods cannot completely solve the problem, and the cost of wastewater treatment for enterprises is very high.

Embodiment 1

[0043] Weigh 100kg of olive fruit, grind it twice on a common grinder, add it to 200L of warm water at 35°C, and stir well to obtain a feed solution; use 0.5mol / L hydrochloric acid aqueous solution to adjust the pH of the feed solution to 6, and add amylase to the final concentration 120U / L, cellulase to a final concentration of 100U / L, enzymatic hydrolysis for 4h. Add temperature-sensitive acid protease (rapidly inactivated above 45°C) to the enzymolysis material again to a final concentration of 80 U / L, enzymatically hydrolyze for 3 hours, and keep warm at 55°C for 35 minutes to obtain material solution I. The feed liquid I is centrifuged on a decanter centrifuge to obtain liquid and wet residue, and the liquid directly enters the disc separator to separate olive oil and waste water I. The obtained olive oil is dried under vacuum condition, left standing and then filtered to obtain the finished olive oil, and the finished oil is inspected. Wastewater I is adsorbed by 732 ca...

Embodiment 2

[0045] Weigh 200kg of olive fruit, grind 3 times on a common grinder, add 1000L effluent liquid I, heat to about 40°C, and stir well to obtain feed liquid II; use 0.5moL / L hydrochloric acid aqueous solution to adjust the pH of the feed liquid to 5.5, add starch Enzyme to the final concentration of 100U / L, cellulase to the final concentration of 80U / L, enzymatic hydrolysis for 3h. Add temperature-sensitive acid protease (rapidly inactivated above 45°C) to the enzymatic hydrolysis solution I again to a final concentration of 80 U / L, enzymatic hydrolysis for 3 hours, and keep warm at above 55°C for 35 minutes to obtain feed solution III. Centrifuge the material liquid III on a decanter centrifuge to obtain liquid and wet residue, and the liquid directly enters the disc separator to separate olive oil and waste water II. The obtained olive oil is dried under vacuum condition, left standing and then filtered to obtain the finished olive oil, and the finished oil is inspected. The ...

Embodiment 3

[0047] 100kg of waste water and 500kg of wet slag from circulating oil production are used as raw materials. After mixing, sterilize at 121°C for 25 minutes, add 90kg of Bacillus subtilis powder (15%) after cooling, cultivate for 48 hours in aerobic fermentation at 37°C, and refrigerate at 0-5°C Get leavening agent.

Abstract

The invention provides a comprehensive method for efficiently preparing olive oil from olive fruit. Olive fruit is ground; water is added; the material liquid pH value is regulated; mixed enzymes are added for enzymolysis; centrifugation is performed to obtain olive oil and waste water; the waste water is subjected to adsorption treatment by 732 cation exchange resin; the cyclic use is performed for many times; waste water generated through cyclic oil preparation is used as raw materials to be used for feed fermentation agents after the fermentation treatment. The protein content is reduced in the olive oil extraction process, so that the emulsification effect is obviously weakened; the content of phenols and saponin in water and oil is obviously reduced; the cyclic and repeated use of the water is facilitated; the discharge quantity of the waste water is reduced. The waste water and the waste slag are directly used for producing feed fermentation agents, so that the environment pollution risk by the waste water is greatly reduced; meanwhile, the utilization value of effective ingredients in the waste water is improved.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to a comprehensive method for producing olive oil from olives, in particular to an aqueous enzymatic method for producing olive oil and a waste recycling method thereof. Background technique [0002] Olive, also known as foreign olive and olean fruit, is a plant of the genus Oleaceae Oleaceae, and is a world-renowned and precious evergreen woody oil plant and fruit tree species. Olive leaves and fruits are used as medicine to treat various diseases. The decoction or infusion of olive leaves is often used as folk medicine for diabetes in Mediterranean countries, which has certain curative effects. Olive leaf extract can be used as a dietary supplement to enhance immune function. Existing data show that olive has anti-arrhythmia, anti-fungal, anti-high cholesterol, lowering blood sugar, lowering blood pressure, anti-inflammation, anti-oxidation, anti-virus, diuretic and other p...
