Cloudy agent could provide the desired opacity of natural juice.

Clouding agents or Cloudy Agent/Cloudifier are a type of food additive used to make beverages such as fruit juices to look more cloudy, and thus more natural-looking and visually appealing, typically by creating an emulsion of oil droplets. [1]

Natural fruit juices are often opalescent. Its turbidity is caused by the protein, oil or pectin particles from plant cell fragments. And consumers would expect the appearance of fruit flavored beverages to have similar color performance as natural fruit juice. To mimic the visual effect, low-juice content soft drinks would add clouding agent in it.

Common clouding agents include palm oil, Arabic gum and extracts of citrus fruits, and some would use Titanium Dioxide to enhance their color strength. Recent studies showed Titanium Dioxide might have risk when in nano-particles size.[2][3]

The illegal use of the plasticizer DEHP in clouding agents has been reported in Taiwan on 2011.[4]
