No, it's in there: "free acidity as citric acid, 3.5 g (per 100 ml)."
TVC: Your figures are looking at ascorbic acid -- aka vitamin C. Rather, we would like to look at citric acid.
Yes, of course. I should have noticed, as I know the difference. Still, an interesting breakdown.
For reference, over here it says "(l)emon juice and lime juice are rich sources of citric acid, containing 1.44 and 1.38 g/oz, respectively." Converting the JFS numbers to g/oz gives us 1.03 g/oz of citric acid for a Meyer.
ETA: if my arithmetic is correct (grams per ounce is a dumb way to measure), oranges have about 0.22 g/oz of citric acid. (Check my math: it's roughly 750 mg/100 ml.)
