6. natural – found naturally, such as extracts from beetroot juice (E162), used as a colouring agent; manmade versions – synthetic identical copies of substances found naturally, such as benzoic acid (E210), used as a preservative; artificial – produced synthetically and not found naturally, such as nisin (E234), used as a preservative in some dairy products and in semolina and tapioca puddings.

13. Conclusion Food additives are making a major contribution to the goal of assuring a better supply of food through increased food production, improved nutritional quality, improved packaging, preservation, and distribution techniques. Consumers can avoid synthetic food colorings by checking labels in grocery stores or by shopping at chains like Whole Foods Market and Trader Joe's, which refuse to sell foods with artificial coloring.

14. Where to look for food additives on a product label?  When buying groceries, these additives are listed (if it’s given by the law) on the food product’s packaging under “INGREDIENTS:” or “CONTAINS:” section, usually next to “Nutrition Information” but the code numbers or names of these additives can be printed on in a small font.  In my opinion placement of the text can be somewhat hidden or even misleading. Any dangerous additives added in the food, if the product contains any, really should be listed visibly and labeled on the pack for instance as “Nasty Additives“.
