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.

Does GMO make the plant produce different chemicals? If so, then if you wanted the plant to grow bigger, what chemical would it produce?

A GMO plant can be made to produce different chemicals. At the initial level the products of added genes are proteins, but proteins can also function as enzymes i.e., they cause chemical reactions and these chemicals can affect growth. A bigger plant could be one that produces more tissue in a given time, or it could be one that is taller; these are different situations. More mass: For a plant to grow bigger it has to make better use of the available resources, such as light and CO2 for... Read More

Some companies do voluntarily have statements that products have ingredients sourced from crops grown from genetically engineered seeds. Some examples are statements like, “Produced with genetic engineering” or “Partially Produced with Genetic Engineering” that appear under the list of ingredients. Read More

Genetic engineering (GE) touches on the routine life of billions of people (but not everyone). Food, clothes, and medicine are commonly made with the help of genetically engineered organisms. Certain medicines, like insulin, could only be mass-produced this way. Fiber for clothes is made less expensive thanks to GE cotton plants. You also PROBABLY sometimes eat plants with a few engineered genes, depending on where you live. But genetic engineering isn’t just for making new or better... Read More
