A database of 793 commercial pomegranate juices was analyzed to produce a profile for authentication of pure pomegranate juice. The database consisted of data from a mix of authentic and adulterated samples. Statistical tools were used to reduce the database to a stable sample set of 477 presumably authentic samples. The profile obtained (mean, SD at 16 Brix) are as follows: fructose (g/100 g) 6.83, 0.50; glucose (g/100 g) 6.66, 0.44; sucrose (g/100 g) 0.00, 0.00; sorbitol (g/100 g) 0.00, 0.01; acidity (g/100 g as citric acid) 1.25, 0.32; citric acid (g/100 g) 1.19, 0.30; malic acid (g/100 g) 0.065, 0.034; tartaric acid (g/100 g) 0.00, 0.00; isocitric acid (mg/kg) 63, 21; potassium (mg/kg) 2320, 400; proline (mg/kg) 7, 5; formol value [milliequivalents/100 g] 1.00, 0.24; 13C/12C ratio [o/oo Pee Dee belemnite]-26.4, 0.8. The profile samples had a consistent anthocyanin pattern consisting of four major peaks corresponding to delphinidin-3,5-diglucoside, delphinidin-3-glucoside, cyanidin-3,5-diglucoside, and cyanidin-3-glucoside. Minor peaks corresponding to pelargonidin-3,5-diglucoside and pelargonidin-3-glucoside were also generally present. No maltose, D-malic acid, or tartaric acid were detected in any of the samples. The profile obtained corresponds closely with previously published data.
Citric and L-malic acids prevail of the organic acids in pomegranate juice while the content of citric acid, as a rule, is several times higher than the content of L-malic. The total acidity of pomegranate juice is high, on average 1.1 g of organic acids is present in 100 cm3 of juice.

FAQ
Does pomegranate have citric acid in it?
Which acid is present in pomegranate?
Are pomegranates citrus?
Is pomegranate an acidic fruit?
Does pomegranate juice contain citric acid?
Unlike citrus fruits, which contain high amounts of citric acid, pomegranates contain mostly oxalic acid, punicic acid, and tartaric acid. Pomegranates also contain lesser acids than citrus fruits. For instance, lemon juice contains around 5-8% of citric acid, while pomegranate juice only contains 0.1 gram of citric acid per 100 ml of juice.
Does pomegranates contain electrolytes?
The pomegranate is a source of potassium, an essential electrolyte in the body. According to scientific evidence, the fruit that has the most electrolytes is the banana.
Are pomegranates more acidic than citrus fruits?
Pomegranates also contain lesser acids than citrus fruits. For instance, lemon juice contains around 5-8% of citric acid, while pomegranate juice only contains 0.1 gram of citric acid per 100 ml of juice. Since pomegranates and citrus fruits belong to different families, they normally grow from different plants.
What substances are present in pomegranate juice?
Other substances that are present in pomegranate juice are phenolic acids, mainly gallic acid and ellagic acid (which belong to hydroxybenzoic acids), as well as caffeic acid, chlorogenic acid, and p-coumaric acid (which belong to hydroxycinnamic acids) [ 24 ].
