Have you noticed that on the labels of food packaging there are strange names and a myriad of rare ingredients? Have you ever wondered where they come from or what is in that food? These are just four of the most chilling examples used by the industry, although of course, not all products have them, it is important to read the labels carefully.

1. TBHQ or better known as Butane

Eating butane is probably not something we have in mind, in fact, one would think it is exclusive for making fire, but it turns out it is another ingredient in chicken nuggets. It is used as an antioxidant to keep them "fresh." Usually found in: Packaged and processed long shelf life products like frozen meals, cookies, potato chips, cereal bars, and fast food.

2. Propylene glycol, in other words antifreeze

Antifreeze? Although it sounds too good to be true, it is not exclusive to cars, If it keeps your engine fresh, why not your body? It is also used in cosmetics, deodorants, moisturizers, and food! It is another ingredient in cookies, salad dressings, and dog food. Usually found in: Cake mixes, salad dressings, low-fat creams, and dog food.

3. Wood pulp: vanillin

Do you eat paper? Believe it or not, this byproduct of the industry produces the pulp that turns into paper and is found in our food and beverages. Usually found in: Yogurt with artificial flavoring, bakery products, candies, and soft drinks.

4. Castoreum or castor

To put it in less crude terms, this product comes from the back end of the beaver, meaning it is extracted from the animal's anal glands and is the star flavoring used in some raspberry-flavored products. Usually found in: Artificial raspberry flavors or flavored products, such as cheap ice creams, candies, fruit-flavored drinks, teas, and yogurts. See original note.
