Bringing up olive oil powder was like deja vu to me. I had a friend come back from a restaurant a few months ago after eating something with olive oil powder and finding fascination with it, so he asked me if I knew what it was. Well, it's just oil blended with equal parts maltodextrin so that when it hits your mouth, the maltodextrin dissolves instantly and you're left with oil in your mouth. The most common form of maltodextrin used is made from tapioca. Tapioca itself is not used.
