Have you ever read a food label and found strange names like monosodium glutamate, sodium benzoate, or aspartame? These names are examples of chemicals in the foods we often consume, sometimes without even realizing it. But don’t panic— not all chemicals are harmful. In fact, many are legally used and safe as long as they are within certain limits.
In this article, we will discuss 10 common food chemicals found in everyday products, from snacks and beverages to processed foods. The goal is to provide balanced, data-based education so you can make wiser choices when selecting foods.
1. Monosodium Glutamate (MSG)
MSG, or flavor enhancer, is often a topic of debate. Its function is to enhance the umami taste in food. Although it has been accused of causing “Chinese Restaurant Syndrome,” scientific research has not found strong evidence that MSG is harmful when used in safe amounts.
2. Sodium Benzoate
Sodium benzoate is a food preservative that prevents the growth of bacteria and fungi. It is commonly found in soft drinks, sauces, and pickled products. The Indonesian FDA (BPOM) sets the maximum usage limit at 600 mg/kg of food.
3. Citric Acid
Citric acid comes from fruits but can also be produced synthetically. It is used as an acidity regulator and to add a fresh taste to beverages and canned foods. It is safe to consume in reasonable amounts.
4. Aspartame
Aspartame is a low-calorie artificial sweetener often used in “diet” or sugar-free products. While it is safe for most people, individuals with phenylketonuria (PKU) must avoid it because they cannot metabolize the phenylalanine it contains.
5. Sodium Nitrite
Commonly used in processed meats such as sausages and ham, this chemical helps preserve the red color of meat and prevents the growth of Clostridium botulinum bacteria. However, if heated too high, it can form carcinogenic compounds, so careful usage is necessary.
6. Tartrazine (E102)
This is a type of synthetic yellow food coloring. It is often found in candies, sodas, and children’s foods. Although allowed, tartrazine can cause allergic reactions in a small number of people.
7. Guar Gum
Guar gum is a thickening agent derived from guar plant seeds. It is used in ice cream, sauces, and frozen foods to maintain texture. It is considered safe and can even aid digestion because it is a soluble fiber.
8. Potassium Sorbate
Potassium sorbate is another preservative that prevents microorganism growth and is widely used in cheese, yogurt, and bread. It dissolves in water and has low toxicity, making it safe when used according to regulations.
9. BHT (Butylated Hydroxytoluene)
Used as a synthetic antioxidant, BHT helps extend the shelf life of oily products such as chips, margarine, and cereals. Although it has raised concerns due to potential long-term effects, BHT is still allowed within certain limits by the FDA and BPOM.
10. Carrageenan
Carrageenan is a thickening agent derived from red seaweed. It is used in milk, yogurt, and plant-based products. Carrageenan is safe for use in foods, although its degraded form (known as poligeenan) is not used in the food industry.
Regulation & Safety: Who Oversees It?
In Indonesia, BPOM (Indonesian Food and Drug Authority) plays a major role in supervising the use of chemicals in foods. Each additive has a maximum usage limit (ADI – Acceptable Daily Intake) based on scientific research.
International organizations like WHO and FAO also regulate and recommend safety standards for food additives to be used globally.
Tips for Choosing Safe Products
-
Read ingredient labels before buying food products.
-
Pay attention to additive codes (such as E100, E202) and the amounts used.
-
Choose products from manufacturers officially registered with BPOM.
-
Use the BPOM Mobile app to check product legality.
-
If in doubt, consult a food or nutrition expert.
Chemicals in foods do not automatically mean danger. In fact, many play an important role in maintaining quality, flavor, and shelf life. What we need to do is educate ourselves about these substances and understand how to consume them wisely.
Conclusion
With proper understanding, we can continue to enjoy our favorite foods without worry, while encouraging the food industry to be more transparent and responsible.
