What is the chemistry of food coloring?
Food-coloring molecules are usually ionic solids, that is, they contain positive and negative ions, which are held together by ionic bonds.
Why does food coloring mix with water chemistry?
The food coloring mixes through the hot water faster than it mixes with the cold water. This is because in hot water, the water molecules have more energy and are moving faster than the molecules of cold water. This makes it easier for the dye to get mixed throughout the hot water.
Why artificial colours are used in food?
Specifically, artificial dyes are added to foods to: Make the food look more appealing and attractive to consumers, especially to children. Masks the absence of brightly colored natural ingredients, such as fruit. Are much cheaper, have a longer shelf-life, and are brighter than most natural food colorings.

Many food dyes are made with insects known as cochineal insects, which are often found on prickly pear cacti in the North American deserts. To make red dye, manufacturers dry the cochineals and grind them into a powder. The powder turns a bright red when mixed with water.
What is the chemical formula for red food coloring?
The molecular formula of Allura Red is C18H14N2Na2O8S2 (MW: 496.42 g/mol) and structural formula is shown in Figure 1. It is dark red in color and water-soluble powder or granules, but slightly soluble in 50% ethanol. The maximum absorption in water is 504 nm, at pH 7 (E1 cm1% = 540).

Why is food coloring dissolved in water but not in the oil?
Oil is made up of different chemical bonds than water is, which is why the two don’t mix. (Water is polar, oil is nonpolar, in case you wanted to know.) Oil is less dense than water so it floats on top. The food coloring only dissolves in water since it is water-based.
