QDoes Xanthin gum come from a genetically modified source

Does Xanthin gum come from a genetically modified source

AExpert Answer

Xanthan gum is made by allowing a very specific bacteria (Xanthomonas campestris) to grow in a liquid solution that contains carbohydrates and other nutrients. While growing, the bacteria uses the carbohydrate to produce the xanthan gum which is released into the liquid. The xanthan gum is then separated completely from the bacteria and the liquid and dried into a powder. Xanthan gum has a chemical structure that is in the same family as carbohydrates but has unique properties for adding texture and volume to foods. Depending on what company is making the xanthan gum, the source of carbohydrate used in the liquid will vary, but could come from a GM crop such as corn. The carbohydrate in the liquid would be very pure and the bacteria converts it into the xanthan gum by rearranging the bonds in the molecule. It would be impossible to tell the source of the carbohydrate in the final xanthan gum. You might think about this like putting eggs into a cake – the eggs went in looking like eggs but when you eat the cake you can’t tell which parts are egg anymore.

Thank you for your question. There are various aspects of your question. I assume your question refers to the use of Agrobacterium rhizogenes by scientists to intentionally transfer genes from the bacterium to plants. Infection and DNA transfer from this bacterium occurs in nature all the time to cause disease. Such transformed plants are not classified as GMOs since transfer occurred naturally. If this is done by scientists then it would be classified as a GMO. Rules and...

I’m a Monsanto scientist who has more than 20 years of experience with genetic modification of plants. I will try to answer your question, even though I don’t ever do experiments on animals, certainly not on humans, of course! Can humans be genetically modified…but a much bigger question is should humans be genetically modified? There are two ways to think about genetic modification of humans (or any animal). One way is modification of somatic cells, and the other is the... Read More

The simple answer is that 20+ years of composition assessments of GMO crops have demonstrated that crop composition is not appreciably affected by the GM process (1). In addition, data collected through that time have indicated that general factors such as the growth environment can contribute to notable variation in component levels (2). Plant agglutinins (or lectins) and amylase inhibitors are examples of anti-nutritional compounds that may be present in crops. The relevance of such a... Read More
