wanted - A speaker on China's food industry

At the upcoming China Speakers' Bureau we will be working with two groups of speakers. One is the group for whom speaking is already a business and we think will fit into the Chinese market as we see it - unfortunately, those two criteria often do not match.
But we are also getting requests that are rather specialized. We try to offer some alternatives to the event organizers, so that makes it sometimes hard to get enough good speakers on some topics, especially in our start-up phase. For this purpose I will start on this blog a "wanted" section for that group of speakers. Later, after our formal launch we will most likely have a seperate weblog for the new business.
Today we are looking for specialists on food in China, especially about cultural differences in appreciating food, food security. The audience will be an international group of specialists in food additives. What we needs is possibly independent food specialists, who know the market in China pretty well and can give an entertaining speech. If you have any positive references, please let me know.
