Food additives are widely used in processed foods to extend shelf life and maintain the desired quality in terms of taste, texture, and appearance. But what exactly do these additives mean, and why are they so frequently used? In this article, we will examine the 5 most commonly used additives and their functions. We will also discuss in which products additives such as emulsifiers and sweeteners are found, along with their potential effects on health.
What Are Food Additives?
Food additives are natural or synthetic substances added to foods during production, processing, preparation, packaging, or storage. These components are used to preserve the quality of food, ensure its safety, or provide desired technological properties. Additives are generally categorized into groups such as preservatives, colorants, flavorings, types of emulsifiers, and sweeteners. The European Union classifies each additive with a specific E-number and regulates the permitted amounts through legal limits based on scientific data.
Sweeteners
Sweeteners are natural or artificial substances added to foods to provide a sweet taste. Often low-calorie or calorie-free, they are preferred by individuals with diabetes and those on a diet. Aspartame, sucralose, and stevia are among the most well-known sweeteners. They are widely used in products ranging from sugar-free beverages to chewing gum, desserts, and packaged foods.
Preservatives
Preservatives prevent the growth of microorganisms, extending the shelf life of food. Common examples include sodium benzoate, potassium sorbate, and nitrates. They are frequently used in meat and dairy products, canned foods, and bakery items.
Natural preservatives such as acetic acid (vinegar) and citric acid (lemon salt) not only help protect food against microbial spoilage but also maintain flavor quality.
Colorants
Colorants, used to make products more visually appealing and natural-looking, can directly influence consumer preferences. Natural colorants include beta-carotene, beet extract, and turmeric. Synthetic ones are identified by codes such as E102 (tartrazine).
Used in sweets, beverages, yogurts, and confectionery, colorants are important not only for aesthetic appearance but also for product standardization.
Thickeners and Stabilizers
Stabilizers are additives that help maintain texture and structure in foods. Natural components such as gelatin and guar gum are used as thickeners and stabilizers in products like yogurt and ice cream.
Legal Regulations on Food Additives
Food additives are considered safe only when used within legally defined limits. These limits are established by national and international authorities based on scientific assessments to protect consumer health.
In Türkiye, additives are regulated under the Turkish Food Codex. This legislation, implemented by the Ministry of Agriculture and Forestry, is largely aligned with the European Union's EFSA (European Food Safety Authority) decisions. Each additive is clearly defined in terms of safe usage dose and application areas.
In the European Union, additives are usually classified with an “E-number.” For example, E322 is lecithin, and E202 is potassium sorbate. These codes indicate that the substance has been approved by the relevant authority and deemed safe for use. In the United States, additives are monitored by the FDA (Food and Drug Administration). Substances with “GRAS” (Generally Recognized As Safe) status are defined based on scientific research and approved for use in foods within specified dosage limits.
Food additives used in Türkiye and globally undergo strict regulatory and scientific control processes, ensuring their safe use. Consumers can track these substances through the E-numbers or additive names listed on product labels, knowing they have been inspected and approved.
Food Safety Starts with Awareness
One of the basic steps toward healthy eating is carefully reading product labels to understand which additives have been used. Knowing the answer to the question “What are food additives?” is important for both health and consumer choice. Being informed about substances like emulsifiers and sweeteners ensures safer and more conscious consumption.
