For thousands of years, people have added ingredients to foods to preserve their freshness and enhance their taste. In the past, people would use things such as vinegar and salt. However, these days one never actually know what kind of unusual ingredients they will find in their meal. Food firms may advertise low calories and natural flavors, but they are less likely to promote the use of human hair, sand or fish bladders. Here are 10 of the most bizarre ingredients hiding in your food.

Polysorbate 60

Polyoxyethylene-(20)-sorbitan monostearate (Polysorbate 60) is an emulsifier which is used as a substitute for cream or milk in baked goods because it does not spoil. Polysorbate 60 is made of petroleum, corn and palm oil.

Silicon Dioxide

Silicon dioxide is the principal chemical compound found in rocks and sands. Amorphous silicon dioxide is one of the most important anti-caking agents. The Food and Drug Administration considers silicon dioxide safe and allows its use, as long as it does not exceed 2 percent of the weight of the food. The compound can be found in pharmaceutical drug tablets, supplements, snack bars, instant soups & sauces, spice powders and processed meat.
