Processed food additives are commonly used to extend shelf life and maintain the desired quality in terms of taste, texture, and appearance. But what do these additives really mean, and why are they used so frequently? In this article, we will examine the five most commonly used additives and their functions. We will also explore which products contain additives such as emulsifiers and sweeteners, as well as the potential health impacts of these substances.
What are Food Additives?
Food additives are natural or synthetic substances added to food during production, processing, preparation, packaging, or storage stages. These components are used to preserve the quality of the food, ensure its safety, or provide specific technological properties. Additives are generally classified into categories such as preservatives, colorants, flavor enhancers, types of emulsifiers, and sweeteners. The European Union classifies each additive with a specific E-code, and their permissible quantities are regulated by scientific assessments based on legal limits.
Sweeteners
Sweeteners are natural or artificial substances added to food to provide a sugar-like taste. They are often preferred by diabetics and individuals on diets due to their low or zero calorie content. Aspartame, sucralose, and stevia are some of the most well-known sweeteners. These substances are widely used in sugar-free beverages, chewing gum, sweets, and packaged foods.
Preservatives
Preservatives prevent the growth of microorganisms, thus 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 such as bread. Natural preservatives, such as acetic acid (vinegar) and citric acid (lemon juice), help prevent microbial spoilage and maintain the flavor quality of food.
Colorants
Colorants are used to make products appear more attractive and natural, which can directly influence consumer preferences. Natural colorants include components such as beta-carotene, beetroot extract, and turmeric. Synthetic colorants are identified by codes like E102 (tartrazine). Colorants are commonly found in sweets, beverages, yogurts, and confectionery, and they play an important role in product standardization as well as aesthetics.
Thickeners and Stabilizers
Stabilizers are additives that help preserve the texture and structure of food. Natural components such as gelatin and guar gum are used in products like yogurt and ice cream to improve consistency and provide structural balance.
Regulations on Food Additives
Food additives are considered safe only when used within the defined legal limits. These limits are determined by national and international authorities through scientific evaluations to ensure consumer health is protected.
In Turkey, food additives are regulated under the Turkish Food Codex, managed by the Ministry of Agriculture and Forestry. This legislation is largely aligned with the European Union’s (EU) EFSA (European Food Safety Authority) decisions. Each additive is thoroughly defined in terms of its safe usage dose and application area.
In the European Union, food additives are typically classified with an "E code." For example, E322 refers to lecithin, and E202 refers to potassium sorbate. These codes indicate that the additive has been approved by the relevant authorities and evaluated for safety.
In the United States, food additives are regulated by the FDA (Food and Drug Administration). Substances that are classified as "GRAS" (Generally Recognized as Safe) are defined based on scientific research, and their use in food products is permitted within established dosage limits.
Food additives are subject to strict regulation and scientific scrutiny both in Turkey and internationally, ensuring their safe use. Consumers can track these additives through the E-codes or names listed on product labels to confirm that they have been inspected and approved.
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.
