Caramel Production in the Sugar Industry

Caramel Production in the Sugar Industry

Caramel is one of the by-products and widely used ingredients in the sugar and confectionery industries. It is produced by heating sugar or sugary compounds, and depending on the production conditions and additives, it comes in various types. Here are the different types of caramel produced in the sugar and confectionery industry:

1. Edible Caramel (Food Caramel)
   • Production Method:
     Sugar (sucrose) is heated directly or indirectly to turn it golden to brown. During this process, sugar molecules break down, creating aromatic and coloring compounds.
   • Characteristics:
     Sweet and slightly bitter taste.
     Golden to light brown color.
   • Applications:
     Used in the production of chocolate, sweets, cakes, beverages, and ice cream.
2. Caramel Coloring (Caramel Color)
   • Production Method:
     Produced by heating sugar in the presence of additives like acids, bases, or salts.
     Depending on the additives, caramel color is divided into four classes:
     • Class I (Plain Caramel): No additives, natural.
     • Class II (Caustic Sulfite Caramel): Made with sulfites.
     • Class III (Ammonia Caramel): Made with ammonia (without sulfites).
     • Class IV (Sulfite Ammonia Caramel): Made with a combination of ammonia and sulfites.
   • Characteristics:
     More bitter taste and darker brown color.
     Typically, it does not add significant flavor to food.
   • Applications:
     Used for coloring carbonated drinks (like cola), sauces, meats, and candies.
3. Soft Caramel
   • Production Method:
     Sugar is combined with other ingredients like milk, cream, or butter and then heated.
   • Characteristics:
     Soft and chewy texture.
     Sweet and buttery taste.
   • Applications:
     Used in soft candies, chocolate fillings, and cakes.
4. Hard Caramel
   • Production Method:
     Sugar is heated with a small amount of water until all the water evaporates, resulting in hard caramel.
   • Characteristics:
     Hard and clear texture.
     High sweetness and concentrated flavor.
   • Applications:
     Used for hard candies and dessert decorations.
5. Liquid Caramel
   • Production Method:
     Sugar is heated and, once caramelized, diluted with water or other solutions.
   • Characteristics:
     Thick, brown-colored liquid.
     Mild to bitter taste, depending on the heating level.
   • Applications:
     Used to decorate desserts, beverages, and ice cream.
6. Industrial Caramel (Caramel Syrup for Industry)
   • Production Method:
     Made from raw sugar or molasses through industrial processing.
     In this type, there is precise control over color, flavor, and consistency.
   • Characteristics:
     Can be either transparent or opaque, depending on food industry needs.
   • Applications:
     Used in the beverage industry, baking, cake and biscuit production.
7. Molasses Caramel
   • Production Method:
     Made from molasses (a by-product of sugar production).
     Has a richer flavor and color compared to other caramels.
   • Characteristics:
     Darker color and stronger flavor.
   • Applications:
     Used in traditional products, brown-colored sweets, and some beverages.

Challenges in Caramel Production in the Sugar Industry

• Temperature Control:
  Excessive heat can cause burning and bitterness in the caramel.
• Selection of Raw Materials:
  The quality of sugar and additives directly impacts the taste and color of the caramel.
• Health Standards:
  Caramel production must adhere to food safety standards.

Caramel Products in Iran

In Iranian sugar factories, caramel is primarily used as a colorant (Class IV) and flavoring agent, especially in the production of liquid sugar, cola beverages, and various sweets.
