Decoding the Cereal Box: How Petroleum-Derived Ingredients Enter Food
While the concept of petroleum in food might sound alarming, it's important to understand that it refers to petrochemicals used as raw materials for creating various products, including food additives. These ingredients, while highly refined, originate from fossil fuels. The primary petroleum-derived additives found in cereals are synthetic food dyes and certain chemical preservatives.
The Role of Artificial Food Dyes
Artificial food dyes are commonly found in cereals and are derived from petroleum to provide bright colors. Ready-to-eat cereals frequently use synthetic dyes. Common examples include Red 40, Yellow 5, Yellow 6, and Blue 1, found in cereals like Froot Loops and Apple Jacks.
The Impact of Petroleum-Derived Preservatives
Petrochemicals are also used in preservatives such as Butylated Hydroxyanisole (BHA) and Butylated Hydroxytoluene (BHT), which help prevent rancidity in cereals. These are used in brands like Cap’n Crunch, Apple Jacks, and Froot Loops. tert-Butylhydroquinone (TBHQ), another petroleum-derived preservative, also helps extend shelf life.
The 2010 Kellogg's Cereal Packaging Recall
In 2010, Kellogg's recalled millions of cereal boxes due to an off-smell and taste. This was traced to methylnaphthalene, a petroleum-based compound from recycled packaging that migrated into the cereal. This event highlighted how petrochemicals can affect food through packaging.
Health Concerns Surrounding Petroleum-Based Additives
Potential health effects of artificial food dyes and preservatives are a concern. Some synthetic dyes have been linked to hyperactivity in children, and certain preservatives like BHA are considered possibly carcinogenic. The FDA approves these additives within limits, but their safety is debated, and some countries have restrictions.
Natural vs. Artificial Cereal: A Comparison
To highlight the differences, here is a comparison of cereals likely containing petroleum-derived additives and those using natural alternatives.
| Feature | Cereals with Petroleum-Derived Additives | Cereals with Natural Ingredients |
|---|---|---|
| Color Source | Bright, synthetic colors (e.g., Red 40, Yellow 5) derived from petroleum. | Colors from natural sources like beet juice, turmeric, annatto, or spirulina extract. |
| Preservative Use | Often contain synthetic antioxidants like BHA, BHT, or TBHQ to prevent spoilage. | Rely on natural antioxidants like Vitamin E (tocopherols) or use minimal processing and tighter packaging. |
| Flavoring | May use synthetic flavorings, which can also be petroleum-derived. | Typically use flavorings from natural sources like fruit, spices, or extracts. |
| Ingredient List | Features chemical names, color numbers, and acronyms (e.g., BHT). | Lists recognizable, whole-food ingredients and natural extracts. |
| Market Appeal | Often marketed towards children with bright colors and cartoon mascots. | Focus on health, transparency, and clean labels to appeal to health-conscious consumers. |
How to Find Cereals Without Petroleum-Derived Ingredients
Making informed choices about cereal involves carefully reading ingredient lists. Look for specific color names or numbers like Red 40, Yellow 5, and Blue 1, and preservatives such as BHA, BHT, or TBHQ. Choose cereals with natural colorings from sources like turmeric, annatto, or vegetable juice, or consider organic options which often restrict synthetic additives.
Conclusion
Petroleum derivatives are used to create common additives like synthetic dyes and preservatives found in many popular cereals, not raw petroleum itself. Being aware of these petrochemical-based ingredients and their associated health concerns is important for making informed choices. Consumers can look for cereals with natural colorings and simpler ingredient lists.
