Problems solved by technology

The jatropha oil has a bright brownish red color, but the color is not stable, and can be destroyed by oxidative rancidity and improper refining. Therefore, the conventional oil refining process cannot be applied to the jacaranda oil due to the high deodorization temperature, and the traditional process must be improved. , can only be obtained by using milder process parameters

Embodiment 1

[0018] A refining method for protecting the color of jatropha oil, comprising the following steps:

[0019] Step 1, hydration degumming: Stir and heat the jatropha crude oil to 70°C, evenly inject an appropriate amount of hot water at 80°C that is 8 times the weight of the jatropha crude oil, stir rapidly at 100r / min to make the colloid fully absorb the water, then use 10r / min min Stir at a slow speed to make the colloidal particles coagulate. Insulated and left standstill for 4h to make the colloid settle, separate the colloid to obtain degummed jatropha oil;

[0020] Step 2. Alkali refining and deacidification: Stir and heat the degummed jatropha oil to 70°C, evenly inject 20 degrees Baume of ethanol calcium hydroxide solution and heat to 75°C, and stir rapidly at 50r / min to fully react the acid and alkali. After completing the acid-base reaction, use 10r / min slow stirring instead, and the oil temperature of the degummed jatropha oil after completing the acid-base reaction ...

Embodiment 2

[0025] A refining method for protecting the color of jatropha oil, comprising the following steps:

[0026] Step 1, hydration degumming: Stir and heat the jatropha crude oil to 75°C, evenly inject an appropriate amount of hot water at 85°C that is 10 times the weight of the jatropha crude oil, stir rapidly at 200r / min to make the gelatin fully absorb the water, then use 30r / min min Stir at a slow speed to make the colloidal particles coagulate. Insulated and left standstill for 5h to make the colloid settle, separate the colloid to obtain degummed jatropha oil;

[0027] Step 2. Alkali refining and deacidification: Stir and heat the degummed jatropha oil to 75°C, evenly inject 25 degrees Baume ethanol calcium hydroxide solution and heat to 80°C, and stir rapidly at 100r / min to fully react the acid and alkali. After completing the acid-base reaction, use 30r / min slow stirring instead, and the oil temperature of the degummed jatropha oil after completing the acid-base reaction i...

Abstract

The invention discloses a refining method for color protection of idesia polycarpa oil. The method comprises the steps of sequentially carrying out hydrated degumming, alkali refining for deacidifying, decoloring and deodorizing. In the deodorization stage, the deodorization temperature is controlled to be 170-200 DEG C, and the degree of vacuum is controlled to be 130-200Pa; by controlling the deodorization temperature and the degree of vacuum, the oil refining is completed at a lower temperature, and the unique color of the oil is protected; furthermore, the refined idesia polycarpa oil hasa translucent brown-red color, is good in quality, high in purity and shelf-stable, and meets the relevant quality standards of China.

Description

technical field [0001] The invention relates to the technical field of oil processing, in particular to a refining method for protecting the color of jatropha oil. It is suitable for the refining of jacaranda oil. Background technique [0002] Fat is one of the three major nutrients for human beings, and edible oil is a necessity in people's daily life. With the progress of society and the improvement of living standards, people have higher and higher requirements for the quality of edible oil, and the pursuit of green and healthy natural edible vegetable oil has become an inevitable trend. [0003] When the oil is separated from the plant seeds, it must contain impurities such as solid plant debris, colloids, pigments and free fatty acids, and must be refined to remove the substances to meet the quality requirements of edible oil. Jacarnia is a kind of woody oil with high content of unsaturated fatty acids. The crude oil of Jacarnia obtained by pressing must be refined to...
