Problems solved by technology

However, the crude oil of jatropha after mechanical pressing is not easy to refine, and it is easy to have problems such as long extraction time and low oil yield of jatropha oil. The content of phospholipid flocs in oil is generally between 2.5% and 3%, and most of them are non-hydratable phospholipids, which are difficult to separate

Embodiment 1

[0033] The present embodiment provides a co-production method for extracting Jatropha tomentosa oil and phospholipids, comprising the following steps:

[0034] S1. Heating the crude jatropha oil. The jatropha crude oil used in this embodiment is obtained by squeezing the jatropha fruit in a press after microwave treatment and hot air drying. Heat jatropha crude oil to 75°C and add citric acid, the amount of citric acid added is 0.15% of the mass of jatropha crude oil, stir for 50 minutes, continue to add water accounting for 4% of the mass of jatropha crude oil, and hydrate for 10 minutes Centrifuged to obtain gum and degummed oil.

[0035] Carry out crude purification treatment to the colloid obtained above: add ethyl acetate to the colloid, the mixed mass ratio of colloid and ethyl acetate is 1:0.8, obtain phospholipid phase and ethyl acetate-oil mixed phase after extraction for 30min, The ethyl acetate-oil mixed phase was subjected to vacuum distillation at a pressure of 0...

Embodiment 2

[0042] The difference between this example and Example 1 is that in S1, phosphoric acid is added after heating the jatropha crude oil to 80°C. Add 5% water to the crude oil of jatropha, and centrifuge after hydration for 15 minutes. When the isolated colloid was subjected to rough purification, the mass ratio of the colloid to ethyl acetate was 1:1, and the extraction time was 38min. After the extraction, the phospholipid phase and the ethyl acetate-oil mixed phase were respectively placed in The ethyl acetate in the recovery process was distilled under reduced pressure under the environment of 0.1 MPa. In S2, after the colloid is dissolved in absolute ethanol, it is heated in a water bath at 70±1°C, and the mass of activated clay added during decolorization is 2% of the mass of the colloid. In S3, add sodium hydroxide lye, stir, and separate after standing for 8 hours. In S4, the temperature of the deacidified oil was adjusted to 80°C, and the amount of water added for wash...

Embodiment 3

[0044] The difference between this example and Example 1 mainly lies in: in S1, phosphoric acid is added after heating the jatropha crude oil to 85°C, the amount of phosphoric acid added is 0.25% of the mass of jatropha crude oil, after stirring for 30 minutes, continue to add The quality of jatropha crude oil is mixed with 6% water, hydrated for 20 minutes and then centrifuged. When the isolated colloid is subjected to rough purification, the mass ratio of the colloid to ethyl acetate is 1:1.2, and the extraction time is 45min. After the extraction, the phospholipid phase and the ethyl acetate-oil mixed phase are respectively placed in The ethyl acetate in the recovery process was distilled under reduced pressure under the environment of 0.12 MPa. In S2, after the colloid is dissolved in absolute ethanol, it is heated in a water bath at 71±1°C, and the mass of activated clay added during decolorization is 2.2% of the mass of the colloid. In S3, after adding sodium hydroxide ...

Abstract

The invention discloses a co-production method for extracting idesia polycarpa grease and phospholipid, and belongs to the technical field of grease and phospholipid extraction and separation. The method comprises the following steps: separating colloid from degummed oil, extracting purified phospholipid from the colloid, and carrying out deacidification, then performing washing, decolorization and deodorization treatment on the degummed oil to obtain refined idesia polycarpa oil. The crude oil of idesia polycarpa is used as the raw material, phospholipid is extracted while the crude oil is refined, and the economic value of idesia polycarpa and the production additional value of the refined crude oil are improved. Meanwhile, the co-production method is simple and easy to popularize, the extracted phospholipid is high in purity, an extraction solvent can be repeatedly used, and the co-production method has important significance in improving economic benefits of production enterprises.

Description

technical field [0001] The invention relates to a co-production method for extracting jatropha oil and phospholipid, and belongs to the technical field of extraction and separation of oil and phospholipid. Background technique [0002] Jagna, also known as chair tung, water wax gourd, oil grape, etc., is a variant of Jagna in the genus Jagna, a deciduous tree. It is mainly distributed in the hills and mountains of the subtropical and temperate southern regions at an altitude of 500 to 2,000 meters from the sea. Slopes are fast-growing tree species that are not strict on climate conditions and have strong growth adaptability, especially in places where the terrain is sunny, the soil is loose, and the drainage is good. Both the fruit and the seeds of Tungia japonica can be used for oil extraction. In the Tungja production area of ​​Mount Maoye at the junction of Sichuan, Shaanxi and Gansu, people have used the fruit to extract oil for hundreds of years. According to reports, ...
