Concentration monitoring of Sterilization Solution
In order to maintain consistency, the concentration of sterilization solution is measured. If the concentration is too high, it remains in the paper packaging, and if it is too low, the effect of sterilization will diminish.
Beverage manufacturers are continually improving quality control measures to ensure that consumers receive safe products.
Case
One beverage manufacturer uses 35% hydrogen peroxide solution to clean paper packaging materials. In-line is installed to check the concentration change while using the same liquid for a week. Besides hydrogen peroxide solution, caustic soda may be used as a sterilizing solution.
Case
Another beverage manufacture installed an in-line meter to measure caustic soda concentration (about 50%) used to wash beverage production lines. Here, the concentration the beverage itself can also be measured by an inline refractometer.

Check for liquid switch
The water is flushed when switching from the disinfectant to a beverage, but this can be confirmed by checking if the concentration is zero.

In modern Japan, many aseptically packaged products are used. A sterile filling and packaging system that makes it possible to preserve food such as milk, other dairy products, dessert, soft drinks, and highly viscous, liquid foods for a long time has been established. Many kinds of containers are used in this process; paper containers, glass, bottles, cans, plastic containers, PET bottles, and others.
For example, in the bottling process of beverage production, a low concentration of hydrogen peroxide is sprayed inside a paper carton to sterilize it. At this point, it is necessary to use in-line refractometers to manage the optimal concentration for sterilization.
