| Wax is a natural compound, which mainly exists in the seed shell and cell wall of oil plants, incorporating into vegetable oil during the pressing and extraction procedures.Rice bran oil and sunflower seed oil have higher contents of wax which can be partially removed by dewaxing.The determination of wax content in vegetable oil can effectively control the quality of vegetable oil.The strengths, weaknesses and the adaptation ranges of insoluble method，turbidimetric method and gas chromatography technology which could determine the content of wax in vegetable oil at home and abroad were analysed and compared.It was conducive to select accurate and reasonable determination method in terms of the wax content in vegetable oil, meanwhile the application of GC-MS in the analysis of wax components was introduced. It was proposed that the establishment of accurate determination and analysis method of wax content had very important significance in quality control of oil and potential applications of wax. |
