The ingredient list of Trader Joe's Brand Spinach Pizza includes "Organic Evaporated Cane Juice (Natural Milled Cane Sugar)." Just as grinding up oranges makes "orange juice", grinding up sugar cane plants makes "cane juice." To get sugar, you evaporate this to get rid of the water.
What fraction of folks who read such ingredient lists could really fooled by calling sugar "evaporated cane juice", especially when it is called "sugar" more directly just a few words later? Could the gain from fooling this few really outweigh the loss of respect from all the other readers Trader Joe's should suffer?
My guess is that other readers are not much offended because they enjoy feeling superior to the fools mislead by such ingredient wordings. The warm glow from feeling superior outweighs any lack of respect, or feeling insulted, and on net encourages such readers to continue to buy the product.
Added: OK, uncle; I accept there are legitimate reasons for this wording, at least for some people.
