Discussion on the Various Sources of GM Foods

The sources of GM foods can be classified into the categories as follow.
1. Corn products, which have not been guaranteed to be non-GM. These could include: textured vegetable protein, hydrolyzed vegetable protein, tofu, soya sauce, polenta and flours and meals made from soya or maize.
2. Derivatives of corn, cotton or oilseed rape, which have not been guaranteed to be non-GM. These could include: vegetable oil, soya derivatives such as soya oil, soya starch, soya fiber, lecithin and vitamin; maize derivatives such as corn oil, cornstarch, modified starch, starch-based granulation additives, corn syrup, xanthan gum and some brands of dextrose, glucose, dextrins, maltodextrins, sorbitol and ascorbic acid and some coating agents or carriers for vitamins, colours and flavours; cotton derivatives such as cottonseed oil; oilseed rape derivatives such as canola.
3. Honey or honey products, which may come from hives within six miles of a GM crop or test site. These products include: honey, propolis, beeswax, royal jelly and pollen.
4. GM micro-organisms or their products. GM micro-organisms include some bacteria, brewers yeasts and bakers yeasts. Products of GM bacteria include riboflavin, aspartame, possibly amino acids such as tryptophan and some of the following enzymes that are used as processing aids: Glucose oxidase, Hemicellulase, Lipase, triacylglycerol, Maltogenic amylase, Protease and Pullulanase. Products of GM yeasts include some yeast extracts, alcohol and fermented products.
5. Food additives, which may come from GM. These additives could include: Riboflavin (made by GM bacteria), Caramel colouring (from chemically treated sugars - can be made from GM cornstarch), Carbon Black (colouring from burnt plant matter - can inc GM crops).
6. Products of GM-fed or treated animals. Such products include meat, gelatin, milk, whey cheese, butter, eggs and albumen from animals raised on feed containing GM ingredients or injected with GM growth hormones such as BST.
