    Study Notes

    Food Additives

    • Food additives are substances added to products to perform specific technological functions, like preserving, adding color, and enhancing flavor.
    • Additives are substances added (intentionally or unintentionally) to basic food products during production, processing, treatment, packaging, transport, and storage.
    • E numbers indicate that an additive has been approved for use by the European Food Safety Authority.
    • The European Food Safety Authority regulates E numbers, ensuring their safety for consumption, regardless of their source (natural or man-made).
    • GRAS (Generally Recognized as Safe) additives have been used for years without known adverse effects, including salt, sugar, and vinegar.
    • Different types of additives exist:
      • Natural: Found naturally, like beetroot juice extract (E162) used as a coloring agent.
      • Synthetic: Man-made identical copies of naturally occurring substances, like benzoic acid (E210) as a preservative.
      • Artificial: Produced synthetically, not found naturally, such as nisin (E234) in some dairy products.
    • Types of food additives include preservatives, food colors, flavor enhancers, high-intensity/low-calorie sweeteners, antioxidants, emulsifiers, and anti-caking agents.
    • Additives help increase shelf life, reduce spoilage, impart unique flavors, and improve texture.
    • Additive class sweeteners are non-nutritive sweeteners providing less than 2% of the caloric value of sucrose and include things like Lactitol, dextrose, aspartame, sorbitol, and mannitol.
    • Anti-caking agents prevent lumping of fine powders while emulsifying agents evenly distribute tiny liquid particles.
    • Testing for safety includes three main types of toxicity tests:
      • 1-Acute toxicity test: Shows the effect of a single additive dose on at least two different animal species.
      • 2-Short-term toxicity test: Determines the effect of varying levels of the additive in diets fed to at least two different animal species over a 30-180 day period.
      • 3-Long-term toxicity test: Evaluates the long-term effects of the additive on animals, assessing issues like chronic diseases, birth defects, mutations, and genetic changes.
    • Food additive advantages include increased shelf life, reduced food poisoning risk, and preventing food waste, alongside making food more appetizing, improving taste and texture, and increasing nutritive value.
    • Disadvantages of food additives include allergic reactions (e.g., tartrazine), concerns about cumulative or combined effects, potential deception by bulking agents, destruction of nutrients (e.g., sulfur dioxide and vitamin B), and aftertaste issues (e.g., saccharine).
    • Immediate health effects of additives include digestive disorders (diarrhea, stomach pain), nervous system problems (hyperactivity, insomnia, irritability), respiratory issues (asthma, sinusitis), and skin problems (itching, rashes, swelling).
    • Long-term health effects might include increased risk of cancer (especially colon cancer), and cardiovascular disease.
    • Toxicity is the general property of matter, while hazard is the capacity for injury under normal use.
    • FDA approval requires a 100-fold safety factor, ensuring that the highest anticipated consumption is a fraction (1%) of the no-effect dose.
