Domestic vanillin industry trends
First, should increase efforts to develop the field of medicine. With the rapid development of domestic pharmaceutical intermediates industry, vanillin in this area will continue to have a larger space for development. Abroad, about 45% of the vanillin used in the production of pharmaceutical intermediates, in the field of domestic consumption accounted for only 30 percent, compared with foreign countries is still a certain gap, and should therefore be actively explore the application of vanillin in the field of pharmaceutical intermediates. Secondly, we must accelerate the the vanillin varieties upgrading. As the aroma is 3 to 4 times that of methyl vanillin, ethyl vanillin, ethyl vanillin instead of methyl vanillin has become a trend in food, feed and other industries in promoting green food . Finally, increased efforts to develop new technology. Vanillin production methods nitrosated and glyoxylic acid method. The Nitrosation technology behind the pollution is serious, foreign countries have been gradually eliminated. Vanillin production in China is mainly nitrosated are currently faced with increasing environmental pressures. Glyoxylic acid method is stable and good product quality, the "three wastes", the direction of development of the vanillin production process, domestic enterprises should actively co-operation with research institutes, as soon as possible to break through the bottleneck of the process of industrialization of the glyoxylic acid method to break Europe and the United States Chinas technological blockade.
