Red Dye #40 is found in almost all categories
of food. In nature, red is a very appealing food color; many
fruits are colored red to indicate ripeness. As animals, we
respond to those visual cues in our food and the food
industry recognizes that fact.
As you'd expect, any food that has more to
do with a laboratory than it does with the blue sky is likely
to have been engineered for taste, longevity and appeal.
Most convenience foods have been carefully
created for ease of manufacture, packaging, transport and
shelf life. They are, in essense, "designed" much
like a blender or a television set. In each case there are
hundreds of factors to consider from the cost of raw components
to the intended use of the product. The look of the product,
whether it's a blender or a new soft drink, is an important
feature because it must appeal to the consumer. For many foods
that means a reddish hue, and one of the most cost effective
and stable ways to achieve that color is with Red40.
