The E-number of citric acid is E 330.
Understanding E-Numbers and Citric Acid's Role in Food
E-numbers are specific codes assigned to substances approved for use as food additives within the European Union, and they are widely recognized globally. These numbers signify that the additive has undergone rigorous safety assessments and is deemed safe for consumption under specified conditions.
Citric acid (E 330) is a naturally occurring organic acid commonly found in citrus fruits like lemons and oranges. Its versatility makes it one of the most widely used food additives, fulfilling several important functions:
- Acidity Regulator: Citric acid's primary role is to control and stabilize the acidity (pH level) of food products. This is vital for food preservation, preventing the growth of undesirable microorganisms, and influencing the texture and flavor profile of various items, from soft drinks to jams.
- Aroma Compound: Beyond its regulatory function, citric acid imparts a distinct tart and sour taste, contributing significantly to the overall flavor and aroma of many foods and beverages.
- Antioxidant Enhancer: While not an antioxidant itself, citric acid is known to remarkably enhance the activity of many other antioxidants present in food. This property helps to protect food from oxidative damage, thereby extending shelf life and maintaining quality.
Below is a summary of citric acid's classification and functions:
| Food Additive | E-Number | Primary Functions |
|---|---|---|
| Citric Acid | E 330 | Acidity Regulator, Aroma Compound, Enhances Antioxidant Activity |
The strategic use of acidity regulators like citric acid is fundamental in modern food production, contributing to both the safety and sensory attributes of countless food items. For more detailed information on acidity regulators and other food additives, reputable sources like the European Food Information Council (Eufic) provide comprehensive insights.
