Just found this by accident, wasn't even trying 
.
Orange Julius is another one. The 70-year old formula for this frothy orange juice drink is owned by International Dairy Queen and is also under lock and key. An IDQ spokesperson says just 3 or 4 people know exactly what goes into the special powder added to orange juice, ice and sugar water that, when blended, magically turns the drink into a sweet, foamy Orange Julius.
The story behind this concoction starts with a man named Julius Freed who was doing a modest business in the 20's selling plain orange juice at a roadside stand. One day he met an ex-chemist named Bill Hamlin. The two became good friends and Hamlin used his chemistry background to devise a natural compound that turned Freed's plain orange juice into the frothier drink we know today. Immediately sales at Freed's little orange juice stand increased five-fold. And the rest is convenience-food history.
So what's in the powdery compound? It seems to be mostly powdered egg whites. When egg whites are whipped in a blender, with other ingredients, the result is a beverage with a light, foamy texture. The sweetness in the original Orange Julius comes from the large quantity of sugar water that is added to the orange juice from a special soda fountain nozzle. It's likely just as simple as that.
