Frozen orange juice concentrate is made through a process of extraction, filtration, and concentration, ultimately removing water to create a concentrated product. The key step is removing water to create the final concentrate. Here's a breakdown:
The Process of Making Frozen Orange Juice Concentrate
-
Extraction and Filtration: The orange juice is extracted from the oranges. The extracted juice is then filtered to separate it into two main components:
- Pulp: The solid materials from the orange.
- Serum (Filtrate Portion): The liquid part of the juice. According to our reference, this filtrate portion is primarily water containing 7%–20% solids.
-
Concentration: The serum, containing water and solids, undergoes concentration. This process aims to remove a significant portion of the water.
-
Freeze Concentration: As mentioned in the reference, freeze concentration is a method used to remove pure water. This involves freezing the water in the serum, creating ice crystals. These ice crystals are then separated from the concentrated juice, effectively reducing the water content.
Step Description Extraction Orange juice is extracted from oranges. Filtration Juice is separated into pulp and serum (filtrate). Concentration Water is removed from the serum, increasing the concentration of solids. Freeze concetration The filtrate portion mainly comprises 7%–20% solids in water and is concentrated by taking out pure water through freeze concentration. -
Freezing: Finally, the concentrated orange juice is frozen to create frozen orange juice concentrate.
