Is Orange Juice Concentrate Acidic or Alkaline?
Orange juice, concentrate (raw) is alkaline: Negative PRAL: alkalizing after digestion.
Classification
Orange juice reconstituted from concentrate matches not-from-concentrate juice at −2.4 per 100 ml. The potassium survives evaporation and rediluting intact, and it is the reason the juice counts as alkaline. Flavor and vitamins may differ, but the mineral balance does not. A 250 ml glass adds about −6.
In the Drinks category, orange juice concentrate (raw) ranks #8 of 80, sorted from alkaline to acid-forming. More alkaline options include Pineapple juice (−2.6), Smoothie, purple (fruits) (−3.1), Carrot juice (−3.8). More acid-forming are Coffee, decaffeinated (−2.3), Coffee, black (−2.3), Lemon juice (−2.3).
Acidic or alkaline: PRAL, not pH
On this site, acidic and alkaline refer to the PRAL (potential renal acid load). It estimates what a food leaves behind once it has been digested: a positive value is acid-forming, a negative value is alkalizing. That is different from the pH of the food itself: a lemon tastes sour, yet its PRAL is −4.0, so it is alkalizing. Your diet does not change your blood pH. It does change how much acid your kidneys have to deal with.

Frequently Asked Questions
Is orange juice concentrate acidic?
It depends on what you mean by acidic. The pH describes the food itself, for example how sour it tastes. The PRAL describes what it leaves behind after digestion: Orange juice, concentrate (raw) has a PRAL of −2.4 per 100 ml, so it counts as alkaline in your daily acid-base balance.
How much orange juice concentrate do I need for a noticeable effect?
A glass (200 ml) of orange juice concentrate adds −4.9 to your daily balance. For comparison: an egg is around +5.4, a slice of cheese around +6. So one serving of orange juice concentrate roughly offsets one of them.
Why is orange juice concentrate alkaline even though it is not a typical alkaline food?
The PRAL depends on the minerals left over after digestion, not on taste or pH. Orange juice, concentrate provides more potassium, magnesium and calcium than phosphorus and protein, so the balance is negative (−2.4).
