If you are wondering does food coloring expire, then you probably have recently bought a fresh jar of some very tasty, attractive, and colorful fruit juice. Maybe you even snuck some in a candy. Before you freak out and throw it away, stop for a moment and think about what may have gone wrong. There is a simple reason that the color has appeared on your juice or candy. The colorants in food coloring do not last forever.
Technically, colorants are not food coloring at all, but a pigment made from a natural mineral called cyanide, which is naturally present in sugar, oil, and water. When these pigments bond with the plasticine coating inside the bottle of juice or candy, the color is created. Most of the colors produced during this process have a slightly greenish tint. When a food coloring product such as Red Diggler or Lemon Yellow slips out of its acrylic container, then the color has already been lost.
Food colorings are made by adding some colorant to an inexpensive plasticine bag and placing food grade colored chips or candies into the bag. These chips and candies are then placed into the plasticine bag, which is then cooked in an oven at low temperatures. This creates the color that is visible on your food. It is a natural process that is completely harmless to humans. However, the longer it is stored in the plasticine bag, the darker the colors will be.
When the color of the food coloring is dark, then it is no good for eating. It is better to use lighter colors such as Yellow or Pink, because these colors do not add any pigment to the food. Just remember, too, that food coloring will not spoil if it is kept in the refrigerator for a few days after it is opened. If you put it in the freezer, however, it will begin to break down. If you store it for more than three days, it may begin to lose its color.
If you are concerned about food coloring not lasting, then you might consider buying a small container of coloring that will last for several weeks. This type of product can be purchased at a variety of different places online. However, it will most likely cost more than plain food coloring. The upside, however, is that this product will provide your family with a healthier snack.
It is important to remember that food coloring should not be bought in bulk, because it will begin to break down soon after it is purchased. If you plan on using it for a long time or are worried about it not lasting, then you should purchase small containers of food coloring that can last for a few weeks. With this little extra effort, you can ensure that your family eats a safer and more colorful meal each day.
