What does what we eat and the petroleum industry have in common?
An estimated 70â80% of synthetic food additives (like artificial colorings, some preservatives, and flavorings) are petroleum-derived or have petroleum-based components.
This doesn't mean they contain crude oil, but that they're chemically synthesized using compounds originally derived from petroleum.
Common petroleum-derived additives include:
Artificial dyes (e.g., Red 40, Yellow 5, Blue 1)
BHA (Butylated hydroxyanisole) and BHT
(Butylated hydroxytoluene) â used as preservatives
Propyl gallate â another antioxidant preservative
TBHQ (tertiary butylhydroquinone) â used in oils and processed foods
Why petroleum?
Petroleum is cheap, versatile, and contains hydrocarbons that serve as building blocks for complex synthetic chemicals.
Note:
Natural additives exist too (like beet juice for coloring or ascorbic acid for preservation), and there's a growing movement toward cleaner, plant-based alternatives.
