Orange juice concentrate, especially frozen orange juice concentrate, is the first in large-scale commercial production. The steps of juicing, filtering, etc. for producing frozen concentrated orange juice are the same as those for producing sweet orange juice. The juice needs to be pasteurized before entering the evaporative concentration to kill microorganisms and inactivate enzymes. The future technical route is to take most of the orange juice for vacuum concentration, and the degree of concentration exceeds the expected requirements, and then mix it with another part without concentration. of orange juice, this process is called the "Cut back" process. Since the unconcentrated original juice has a good flavor, it can make up for the defects of concentrated orange juice and significantly improve the flavor of the product. Another method is to add an appropriate amount of aroma substances collected during evaporative concentration back to the concentrated juice to compensate for the loss of volatilization of aroma substances during the concentration process.
1. Evaporative concentration
The juice is sent from the heat exchanger or mixing tank to the evaporator for concentration. The most common concentrating evaporator in the citrus industry is the fast-heating instantaneous evaporator, in which the juice can be concentrated from 12°Brix to 65°Brix in a short period of time when it is fed into the evaporator.
2. Flavor recovery
The TASTE evaporator can also be equipped with a flavor recovery device, which can recover the flavor components in the juice vapor during concentration.
3. Canning and packaging for storage
The concentrated juice from the evaporator is collected into the cooling tank, further cooled and cooled, and the fresh original orange juice is recalled through the "Cut back" process to dilute the concentrated juice to 45°Brix or add an appropriate amount of recovered aromatic substances. Before canning, it is pumped through a continuous scraper freezer and cooled for canning. Generally, large drums lined with polyethylene can be used, or polyethylene plastic containers can be used. Frozen orange juice concentrate is stored in a freezer at approximately -18°C. Frozen concentrated orange juice is available in various sizes and packages in the market, and is finally mixed into original juice or fruit juice beverages.
