Orange juice is an unfermented juice abstracted from mature oranges of the species Citrus sinensis. Orange juice production ‘enmasse’ in a factory postulates a peculiar processing as it should be preserved. So, ‘how is orange juice made in a factory?’ is a common and a very popular question around the globe.
Ingredients
Obviously oranges are the primary ingredients in the orange juice production. In general, conflate of several types of oranges such as navel, Mandarin, and Valencia, is used to prepare a particular flavor to avoid bitterness. The fruit itself comprises a lot of natural materials such as water, sugars and relish compounds that can constitute the flavor of the juice. A small amount of preservatives such as sulfur dioxide or sodium benzoate and antioxidants such as ascorbic acid, alpha tocopherol, EDTA, BHA, or BHT are also added. Citric acid and other sweetners are also used in orange juice production.

How is orange juice made in a factory?    
The process of orange juice production includes seven significant steps such as:
•    Harvesting/collection
•    Cleaning/Grading
•    Extraction
•    Concentration
•    Reconstitution
•    Pasteurization
•    Packaging/filling

Oranges are reaped from large plantations. The quality of the fruit is scrutinized and ranged before using it. The qualified fruit is then washed with a detergent to take out dirt and debris and subjugates the microbes. Proper extraction of juice is crucial to optimize the production process as well as the quality of the juice, as orange contains thick peels with bitter resins. The pulled out liquid is strained through a stainless steel screen. The filtrate can be pasteurized and chilled at this stage if it is meant for an immediate juice.
But in normal cases with a factory, it is concentrated. Normally the squeezed juice is concentrated with TASTE, a Thermally Accelerated Short-Time Evaporator. A Concentrated juice extract is more or less five times saturated than squeezed juice. The pulp in it is isolated from the juice by ultra-filtration and pasteurized. After the ultra filtration, the concentrated pulp is stored in refrigerated bulk tanks of stainless steel, to keep it ready for packaging
Reconstitution is done after this process by adding water and other flavors to make it potable in terms of desired sugar to acid ratio, color, and flavor. Once reconstitution is over the available juice is subjected to pasteurization to avoid spoilage of the juice, even though it has some natural protection from bacteria due to its low pH. Usually the juice shows a tendency to get separated from the pulp. The pasteurization process also restricts this by inactivating certain enzymes.  After the pasteurization, the juice is sending to be packed. It is filled while hot to insure sterility. Quality is ascertained throughout the process, till collection of fruits to packing.
