E335 – Sodium Tartrates

E335, known as Sodium Tartrates, includes sodium salts of tartaric acid, primarily disodium tartrate. These compounds function as acidity regulators, emulsifiers, and stabilizers in various food products. 

Safety: Sodium Tartrates are generally recognized as safe for consumption within regulated limits. 

Purpose in Products

Sodium Tartrates serve multiple functions in the food industry:

  • Acidity Regulation: They help maintain desired pH levels in foods and beverages, ensuring product stability and taste consistency.
  • Emulsification: Assist in blending ingredients that typically do not mix well, such as oil and water.
  • Stabilization: Enhance the texture and shelf life of various products.

Common applications include:

  • Jellies and Jams: To control acidity and improve texture.
  • Margarine: As an emulsifier to maintain consistency.
  • Sausage Casings: To aid in binding and stability.

Health Considerations

Sodium Tartrates are generally safe for consumption. However, excessive intake may lead to digestive discomfort, such as abdominal pain or diarrhea. Individuals with specific health conditions should monitor their intake accordingly. 

Impact on Children

Sodium Tartrates are safe for children when consumed within recommended dietary limits. They can contribute to the palatability of various food products, encouraging the consumption of fruit-flavored items. However, moderation is advised to prevent potential digestive discomfort from excessive intake.

Impact on Taste

Sodium Tartrates have minimal impact on the taste of food products, as they are used primarily to regulate acidity and stabilize textures without imparting a distinct flavor.

Compatibility with Other Additives

Sodium Tartrates are compatible with various food additives and ingredients, making them versatile in food processing. They can be used alongside other acidity regulators, stabilizers, and preservatives to achieve desired product qualities.

Natural Occurrence

Tartaric acid, from which Sodium Tartrates are derived, occurs naturally in many plants, especially in grapes. During prolonged storage of wine, a sediment of potassium tartrate, known as tartar, forms in barrels and bottles. This sediment serves as the starting substance for the chemical production of tartaric acid (E334), sodium tartrate (E335), and potassium sodium tartrate (E337). 

Alternatives and Substitutes

Alternatives to Sodium Tartrates include other acidity regulators and emulsifiers, such as:

  • Citric Acid (E330): A common acidity regulator and flavoring agent.
  • Potassium Tartrates (E336): Serve as acidity regulators and can also provide potassium fortification.
  • Lactic Acid (E270): Found in fermented products, offering a milder acidity.

The choice of alternative depends on the specific application and desired properties of the food product.

Regulation

Sodium Tartrates (E335) are approved for use as food additives in many countries, including those in the European Union and the United States. Regulatory agencies have established acceptable daily intake levels to ensure consumer safety. 

Conclusion

E335 (Sodium Tartrates) are versatile food additives employed as acidity regulators, emulsifiers, and stabilizers in various products. When used within regulatory guidelines, they are generally safe for consumption, contributing to product quality and stability. Individuals with specific health conditions should monitor their intake accordingly.
