Studies On Enriching LA And Synthesizing CLA From "Jinguan No.1" Kenaf Seeds Oil

The kenaf plant is considered one of futuristic crops in 21 century . To develop multi-purpose complex utilization and process kenaf seeds oil in depth , the application of kenaf seeds oil , to development of new healthy edible oil , enrichment of linoleic acid and synthesis of conjugated linoleic acid , is studied in the article . The sample is "Jin Guang No.1" , a new variety of kenaf with high yield and quality which is selected and cultivated by Fujian Agriculture and Forestry University lately . The major results are as follows:1. Mensuration of fatty gross in "Jin Guang No.l" seeds by Soxhlet extraction shows that seeds of "Jin Guang No.1" have a comparatively high amount of fat, up to 23.4%, compared with some common oil plants . And its yield per hectare is 2550 kg , twice than the output of common varieties of kenaf. Therefore, "Jin Guang No.1" is a specific variety of oil kenaf plant.2. Analysis of physiochemical properties of kenaf seeds oil of "Jin Guang No. 1 ",acording to the national standard of fatty mensuration, shows that the oil has the necessary qualifications in "sanitary criterion of edible plant oil".3. Fatty acids content of kenaf seeds oil of "Jin Guang No.l" is also mensurated by Gas Chromatography. GC results show that the new oil contains more than 80% of unsaturated fatty acids. The main acids are oleic acid and linoleic acid, in which oleic acid accounts for 28.13% and linoleic acid for 51.81% of the total fatty acids. Outstandingly, the result reveals edible and medical care values of kenaf seeds oil of "Jin Guang No.1" .4. Orthogonal experiment of L16(45) , with four factors such as alkali concentration, excess alkali, alkali-refining temperature and water quantity, is designed to optimize the refining technics, increase refining efficiency and improve physiochemical properties of kenaf seeds oil. The results show that in the refining process, excess alkali and alkali-refining temperature have extremely remarkable effects on the refining efficiency (P<0.01), and so does the interaction between alkali concentration and water quantity while each of them has no remarkable effects. Then the optimal refining conditions are...
