What Type of Caramel Color Is E150d?
E150d belongs to Class IV caramel color.
It is also known as sulfite ammonia caramel color. It is produced by heating carbohydrates
with ammonia and sulfite compounds, creating a water-soluble caramel color with strong color
intensity and good stability in acidic environments.
Compared with E150a, E150d usually provides deeper brown to black-brown color and stronger
acid stability, making it suitable for food manufacturers producing cola drinks, vinegar,
soy sauce, sauces, compound seasonings, tea beverages, coffee beverages, and similar products.

E150a vs E150d: Key Differences
E150a and E150d are both caramel colors, but they are not the same. E150a is Class I plain
caramel, while E150d is Class IV sulfite ammonia caramel. The right choice depends on product
formula, target color, pH, label requirements, and processing conditions.
| Item | E150a | E150d |
|---|
| Class | Class I Plain Caramel | Class IV Sulfite Ammonia Caramel |
| Processing Aid | No ammonia or sulfite compounds | Made with ammonia and sulfite compounds |
