Food Dyes Presented By: Kaylyn Kimpel,
& Samantha Uhrig Natural Food Colors Synthetic Food Colors Interesting Facts Dangers Pictures Interesting Facts Pictures Steps Through History History of Food Dyes 1. Food colors have been used for thousands of years.
2. Evidence shows that the Romans colored wine; and since the 14th century, dairy products, such as butter, have been dyed to give them a yellow color. 1. The first food colors utilized were natural food colors.
2.Some examples of natural food colors are: turmeric, paprika, saffron, carrot oil, red beets, and carmine.
3.They are divided into three classes: carotenoids, chlorophylls, and anthocyanins. 1. Synthetic food colors do not exist on their own in nature, but rather are designed and produced in a laboratory.
2. There are seven artificial food colors that are approved for use today: FD&C Blue No. 1, FD&C Green No. 3, FD&C Red No. 3, FD&C Blue No. 2, FD&C Yellow No. 5, FD&C Yellow No. 6, and FD&C Red. No. 40.
3. As the numbers would imply, many more than these seven colors have been used but were discovered to be too harmful to health.
4. The synthetics colors are salts that contain anions that provide vibrant, long lasting color. This is what attracts foods to the human eye. 1. Some of the synthetic colors that have been restricted over the years due to health hazards are: FD&C Red No. 2, FD&C Red No. 4, FD&C Red No. 32, FD&C Orange No. 1, FD&C Orange No. 2, FD&C Yellow No. 1,2,3, and 4, FD&C Violet No. 1.
2. Since natural food colors are just that, natural, they are not subject to any kind of governmental regulation, whereas synthetic colors are. Pictures THE END! 1. During the 19th century, naturally occurring heavy-metal compounds were used as colorants.
2. In 1906, the Food & Drug act was enacted. At that time, only seven of the many different synthetic colorants in use were approved for continued use of food additives. Today only two of those original seven are still in use, though others have been added.
3. In 1938, the Food, Drug, and Cosmetic Act was passed. This gave the government the right to remove products considered harmful from the market.
4. In 1958, Congress created specific guidelines for testing food additives in the Food Additives Amendment.
5. Synthetic food colorants are also subjected to animal testing. Background
