What is Food Additive E262 ?
E262, known as sodium acetate, is a food additive that plays a crucial role in preserving and enhancing the flavor of various food products. Sodium acetate is often found in crystalline form and is highly soluble in water.
E262 refers to two specific compounds: sodium acetate (E262(i)) and sodium diacetate (E262(ii)). Both are sodium salts of acetic acid, a weak organic acid that is the main component of vinegar.
- Sodium Acetate (E262(i)): This compound is typically used as a preservative and acidity regulator in foods. It is known for its ability to prevent microbial growth, thereby extending the shelf life of products.
- Sodium Diacetate (E262(ii)): This is a mixture of sodium acetate and acetic acid (E260). It is more commonly used for its flavor-enhancing properties and is particularly popular in snacks like chips

What is the Recommended Daily Dose ?
E262 is generally recognized as safe and is approved for use in foods by the European Food Safety Authority (EFSA). When used within prescribed limits, it poses no significant health risks.
The maximum daily amount allowed per body weight is 15 mg/kg. It is not permitted in foods intended for infants and young children. However, excessive consumption can lead to certain side effects, such as increased sodium intake, which can be a concern for individuals with hypertension or cardiovascular diseases.
In Which Products Can E262 be Found ? InfoCons Consumer Protection informs you that the primary functions of E 262 in food products include :
- Preservation: Sodium acetate inhibits the growth of bacteria and fungi, making it valuable in preserving a wide range of food items. It is commonly used in bread, baked goods, and processed meats.
- Acidity Regulation: E262 helps maintain the desired pH level in foods, which is crucial for both flavor and preservation. This property is particularly beneficial in sauces, dressings, and condiments.
- Flavor Enhancement: Sodium diacetate is especially effective at enhancing flavors. It imparts a slightly tangy taste, which is why it is frequently used in savory snacks.
- Buffering Agent: E262 can act as a buffer, stabilizing the acidity of food products and ensuring consistency in flavor and texture.

Contraindications and Risks
While E262 is considered a safe food additive, there are some potential risks:
- Increased Total Sodium Intake: Since sodium acetate contributes to the overall sodium content in food, it is essential for consumers to be mindful of their total sodium intake to avoid health issues related to high sodium levels.
- Allergies and Sensitivities: Although rare, some individuals may exhibit allergies to food additives, including sodium acetates. It is advisable for such individuals to check food labels if they suspect an allergic reaction to these compounds.
Conclusion
E262, or sodium acetate, is a vital food additive that serves multiple functions in food preservation, flavor enhancement, and acidity regulation. Its widespread use and safety profile make it an invaluable component in the food industry.
As with any food additive, moderation is key, and being informed about its presence in food products can help consumers make healthier choices.
