Food additives are substances added to food to preserve flavor or enhance its taste and appearance. Among these, E252, also known as potassium nitrate, is a widely used additive that often raises questions regarding its safety and role in food preservation.

Sodium bicarbonate (NaHCO₃) is a white crystalline powder that is commonly used as a leavening agent in baking. It has a slightly alkaline nature and reacts with acids to produce carbon dioxide gas. This reaction is responsible for the leavening effect, which helps baked goods rise and achieve a lighter texture.

However, the increasing use of flavoring agents also raises questions regarding food transparency and authenticity. Consumers are becoming more aware of what goes into their food and are demanding products that are both health-conscious and minimally processed. Companies recognize this trend, striving to create products with recognizable and natural flavoring agents rather than relying solely on synthetic counterparts. This shift not only caters to consumer demands but also supports sustainability and local agriculture.

On the other hand, synthetic stabilizers, such as xanthan gum and carrageenan, are widely used in the food industry due to their effectiveness and versatility. Xanthan gum, derived from the fermentation of glucose by the bacteria Xanthomonas campestris, is commonly used in salad dressings, sauces, and gluten-free baked goods. It helps to prevent the separation of oil and vinegar in dressings and provides a creamy mouthfeel without altering the flavor of the product. Similarly, carrageenan, extracted from red seaweed, is often used in dairy products, non-dairy creamers, and processed meats to improve texture and maintain moisture.

Scientific Evidence and Perspectives

BHT/BHA/TBHQ — Butylated hydroxytoluene, butylated hydroxyanisole and tert-butylhydroquinone are synthetic antioxidants used to prevent rancidity. The FDA regards these chemicals as safe in food in low doses; the Center for Science in the Public Interest gives an avoid rating to BHA and TBHQ and caution to BHT over cancer risks.

The cyanidation process begins with the crushing and grinding of gold-bearing ores to a fine powder. Once the ore is sufficiently prepared, it is mixed with a dilute cyanide solution, typically sodium cyanide. The cyanide ions react with the gold present in the ore, forming a soluble gold-cyanide complex. This reaction occurs in a controlled environment — often in large tanks — to enhance the contact between the ore and the solution.
