Then why not use the whole name of the plant: "sugarcane"? There are other cane grasses and I doubt even one has its juice evaporated for food.
And you don't have to be an idiot to be fooled by this. A PhD I worked with had some "health bars". I read the ingredients and either the first or second was evaporated cane juice. He wasn't amused when he realized he had been duped by the health claim of the bar.
That’s one dumb, and/or delusional PhD.
