Antioxidant compounds and pH-adjusting agents in food products: operational mechanisms and health implications of their use

Contemporary food products frequently incorporate specialized additives, including compounds that inhibit oxidative degradation and substances that modulate acid-base balance. What are their genuine chemical characteristics, for what purposes are they integrated into food formulations, and what potential—both beneficial and potentially adverse—effects might they exert on human physiology following prolonged dietary exposure?
Antioxidants and acidity regulators
Antioxidants are compounds that cause a food containing fat to stay fresh for longer and not swallow too quickly. They are obtained from natural sources or by chemical manufacturing. Acidity regulators are substances added to food to alter or stabilize its acidity and a pH coefficient that ensures product safety by inhibiting the growth of bacteria. They also affect the enzymes in food while maintaining its freshness for longer.
Antioxidants and health
Natural antioxidants added to food are vitamins C, E, or β-carotene. They are found in margarines, oils, and sweets. They're safe for our health, so we don't have to give up buying if we see the symbols in the composition of the product: E300E304, E306, E307, or E308. We can also find synthetic antioxidants in food like BHA, BHT, or vinegar and gallic acid, which negatively affect our health. In large quantities, they can cause stomach pain, allergies, or reduce iron absorption.
Acidity and health regulators
Most acidity regulators are found in food products only in doses that are considered safe and harmless. However, it should be noted that some, regardless of the quantity, can cause allergic reactions. Manufacturers are legally obliged to include information on product labels about acidity controllers, colorants and sweeteners.
