Orange juice from concentrate is indirectly from orange fruit. The oranges are processed after harvest into orange juice concentrate base minus orange oils an some orange solids. The excess water is removed and the concentrate base is then frozen for storage or export. The orange oil, orange solids and other (((ingredients))) are processed into (((flavor packs))) also for storage or export. When you want to make orange juice, you combine the concentrate base (which has practically no flavor), add (((flavor packs))) and add water to reconstitute it into (((juice))). Add in some other (((ingredients))), package it and sell it in stores as (((orange juice))). Profit.
Honestly, excluding the (((ingredients))), this process is pretty much the only way to have orange juice outside of citrus season. Too bad the jews have to fuck with it to make (((orange juice drink))) instead of mostly pure OJ. Fucking jews.
