Beeswax is usually refined and deodourized by the method of steam distillation. However, deodourization cannot be done completely in this way because of phenomenon of so-called re-odouring.
Some of the odour ingredients or the other unstable chemical components which cannot be removed by the method of steam distillation, react with oxygen gradually after refining of beeswax. This reaction brings phenomenon of re-odouring.
We have observed lapse of change of the quality of refined beeswax deodourized by centrifugal molecular still method for these seven years, however no phenomenon of re-odouring stated as the above have been detected till now, because some of the odour ingredients or the other unstable chemical components had been completely removed by the method of centrifugal molecular still.
This review will discuss the results of study of industrial beeswax which is not spoiled of good trait in natural beeswax and has no phenomenon of re-odouring low boiling volatiles of beeswax, some of the odour ingredients or the other unstable chemical components were studied using the combination methds of gas chromatography-mass spectrometry-odour assessment. 55 compounds, including 13 hydrocarbons, 15 aldehydes, 5 alcohols, 6 ketones, 9 acids, 4 lactones, were conclusively identified.
