"Loaded with flavor" is a phrase the inventors at Pepsico meant literally when they developed this aerogel invention. It is capable of carrying high flavor loads, helped by supercritical CO2.

Flavor-loaded, food grade aerogel
WIPO Patent Application WO/2016/032733
Publication date: March 3, 2016
Assignee: Pepsico, Inc.

In this patent application, food grade aerogels are used for the impregnation of flavor with the help of supercritical carbon dioxide.

According to the inventors, the aerogels possess high flavor-loading capacity, up to ~70%, which is well above the average loading capacity of most common flavor encapsulation technologies via spray-drying (typically ~20% capacity loading). 

In addition, the technology is said to maintain the integrity of flavors, particularly top notes.
