Once, I had the pleasure of seeing where Ronald's [McDonalds] orange juice comes from. It's delivered in a giant plastic sack of Day-Glo goo. One one side of it is a little tube they attach to the juice machine, then they roll the sack inside and close it up. The goo is mixed with water to deliver to you, the happy customer, a beverage that tastes a bit like orange juice and a bit like the inside of a garbage bag. (p. 136)McDonalds orange juice is made by Minute Maid. Its ingredients?
That's it. No added sugar. No preservatives. Just juice from oranges.
The orange juice is concentrated to make it easier to ship and store. It's then remixed with water at the restaurant and served. It's no different than buying frozen orange juice concentrate at the grocery store, taking it home, mixing it with water, and drinking it.
