Juicy Juice among other brands touts "100% juice" however if you leave it undisturbed for months on the shelf it never seems to develop any sediment. How can they be 100% juice and not have any solids? What exact process are they using to remove all the sediment and or perfectly homogenize the liquid? You will notice other shelf stable 100% juice brands tend to have a sediment, how do the large brands get around that, while still being pure juice? Is there an FDA definition of "Juice"?
Sorry, this seemed to turn into many questions.
Just going to add, it’s also often not anywhere near 100% juice from the fruit whose flavor is on the package. They’re mostly pear, apple, and/or grape juice, even if the box says raspberry.
And, 100% juice may include flavor packs and additives as long as they are made from fruit sources. Fruit doesn’t always taste the same, but Juicy Juice always tastes the same.
