[0022] How to Detoxify Jatropha Seed Oil

[0023] The mature and naturally dried jatropha seeds are shelled to obtain the kernels, and the jatropha seed oil is obtained by pressing with a low-temperature oil press. The obtained jatropha seed oil is treated with appropriate ultraviolet light irradiation technology, and then eluted with ethanol to obtain detoxified jatropha seed oil.

[0024] First, the UV photodegradation process is as follows: the UV photodegradation process is carried out in a darkroom. Take 20mL of Jatropha curcas seed oil in a quartz test tube, place it under ultraviolet light, and sample and analyze according to a certain time interval. By changing the reaction quartz test tube and light source The distance of the incident light is adjusted, and its intensity is measured with a UV light meter. Its technical parameters are: the intensity of ultraviolet light is 200-1000μw / cm 2 ; The ultraviolet light source is: UVA: 315-400nm, UVC: 200-275nm and UVA+UVC; ...

Abstract

The invention provides a jatropha curcas seed oil detoxification method, and belongs to the field of fine and deep processing of jatropha curcas seeds and plant oil production, wherein ultraviolet light irradiation is adopted to degrade phorbol ester, and then ethanol with an appropriate concentration is adopted to elute, such that toxin residue in jatropha curcas seed oil is solved. The method has the following characteristics that: equipment requirements are not high, the production process is simple, the production process conditions are mild, operations are convenient, industrialization implementation can be achieved, strong acid and strong alkali treatments are not required, an environmentally friendly property is provided, the used raw material ethanol is a commonly-used reagent in the field of deep processing of vegetable oils, and is suitable for large-scale use, and more importantly important significance is provided for releases of edible oil strategy safety crisis in China.

Description

technical field [0001] The invention relates to the field of vegetable oil production, in particular to a method for removing toxic substances from Jatropha curcas seed oil. Background technique [0002] Edible oil is a strategic necessity to ensure national food security and national health. At present, the self-supply gap of my country's edible vegetable oil consumption is very large, and about 60% of the vegetable oil needs to be provided by the international market, which poses a severe challenge to the security of domestic edible oil supply. Since medical nutritionists recommended edible woody edible oils with high unsaturated fatty acid content in the 1950s, the development of woody edible oils has become the development trend of the world's edible oil production. Many countries attach great importance to the development of woody edible oil production. According to the characteristics of mountains and hills in southern my country, the development of woody plant oil so...
