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 commonly used? In this article, we will explore the five most frequently used additives and their functions. We will also look at which products contain additives such as emulsifiers and sweeteners, and discuss 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 ingredients are used to preserve quality, ensure safety, or provide specific technological properties. Additives are generally categorized into groups such as preservatives, colorants, flavorings, types of emulsifiers and sweeteners. In the European Union, each additive is classified under a specific E-number, and their permissible levels of use are regulated through legally defined limits based on scientific evidence.
Sweeteners
Sweeteners are natural or artificial substances added to foods to provide a sweet taste. Since they are usually low in calories or calorie-free, they are often preferred by individuals with diabetes and those following a diet. Aspartame, sucralose, and stevia are among the most well-known examples. Sweeteners are widely used in a variety of products ranging from sugar-free beverages and chewing gum to desserts and packaged foods.
Preservatives
Preservatives extend the shelf life of foods by inhibiting the growth of microorganisms. Common examples include sodium benzoate, potassium sorbate, and nitrates. They are frequently used in meat and dairy products, canned foods, and baked goods such as bread. Natural preservatives such as acetic acid (vinegar) and citric acid (lemon salt) not only enhance resistance to microbial spoilage but also help maintain flavor quality.
Colorants
Colorants are used to make products more visually appealing and natural-looking, directly influencing consumer preferences. Natural colorants include compounds such as beta-carotene, beet extract, and turmeric. Synthetic ones are identified with codes such as E102 (tartrazine). Commonly used in desserts, beverages, yogurts, and confectionery, colorants are important not only for aesthetic purposes but also for product standardization.
Thickeners and Stabilizers
Stabilizers are additives that help preserve the consistency and structure of foods. Natural ingredients such as gelatin and guar gum are used in products like yogurt and ice cream as thickeners and structural stabilizers.
Legal Regulations on Food Additives
Food additives are considered safe only when used within legally established limits. These limits are determined through scientific evaluations by national and international authorities with the aim of protecting consumer health.
In Türkiye, additives are regulated under the Turkish Food Codex. This legislation, overseen by the Ministry of Agriculture and Forestry, is largely aligned with the decisions of the European Union’s EFSA (European Food Safety Authority). Each additive is defined in detail in terms of safe dosage and permitted areas of use.
In the European Union, additives are typically classified using “E-numbers.” For example, E322 refers to lecithin, and E202 to potassium sorbate. These codes indicate that the substance has been approved by the relevant authorities and permitted for use after safety evaluations. In the United States, additives are regulated by the FDA (Food and Drug Administration). Substances classified as ‘GRAS’ (Generally Recognized As Safe) are identified based on scientific data and are allowed in food products within defined dosage limits.
Food additives used in products undergo strict regulatory and scientific control processes both in Türkiye and internationally, with safety as the guiding principle. Consumers can track these additives via the E-numbers or names listed on product labels, confirming that they have been reviewed and approved by authorities.
Food Safety Begins with Awareness
One of the essential steps in healthy eating is carefully examining product labels to understand which additives are used. Knowing what food additives are is crucial for both health and personal preference. Being informed about substances like emulsifiers and sweeteners fosters safe and conscious consumption.
