Boyue Activated Carbon – Recommended Activated Carbon for Decolorization in Japanese Food Products

Case Study of Decolorization Application in Japanese Food Factories
In the Japanese food industry, activated carbon is widely used in decolorization and impurity removal processes to ensure the purity and safety of food. Taking the production process of powdered vinegar as an example:

In the production process of powdered vinegar, 1000 liters of brewed rice vinegar is first mixed with 30 kg of sodium hydroxide and neutralized to pH 7.2. Then, it is concentrated under reduced pressure at 500 mmHg and 50°C to 40% of the initial volume, resulting in a filtered sodium acetate solution. Next, activated carbon is added to the solution, stirred for decolorization, and finally filtered to remove the activated carbon. The resulting powdered sodium acetate is then spray-dried.

In this crucial decolorization step, the choice of activated carbon directly affects the color and purity of the final product.
