| Abstract: |
| The oil-tea camellia seed oil was prepared in pilot scale and the main quality indicators and nutritional indicators of oil-tea camellia seed oil in each processing procedure were determined so as to try two kinds of appropriate processing technologies.Processing Ⅰ：the oil-tea camellia seeds were pressed by screw press after fried at 100-105℃，and the crude oil was injected into degumming tank after coarse filtration and precipitation.The oil was degummed by citric acid, washed by sodium chloride water solution,dehydrated by passing compressed air in vacuum for 4 h，and pumped into winterization tank.After winterization and fine filtration, the oil-tea camellia seed oil product was finally obtained.Processing Ⅱ：the oil-tea camellia seeds were pressed by screw press after fried at 140-145℃and adjusted water; the crude oil was filtered by 100 meshes filter cloth and pumped into winterization tank; after winterization and fine filtration，the oil-tea camellia seed oil product was obtained.The track determination of oil-tea camellia seed oil showed that both of the two kinds of processing technologies could effectively keep nutritional ingredients in oil-tea camellia seed oil and the oil-tea camellia seed oil products were accord with relevant national standards. |
