Chemical composition and guide values of pomegranate juice

Abstract

To contribute for setting reference guideline, chemical composition of 23 pomegranate juice samples from concentrate was investigated. The samples were collected in 2006 from 6 different producer companies. According to the findings, titratable acidity changed between 8.3-17.4 g/L (as anhydrous citric acid), citric acid 6.6-13.6 g/L, L-malic acid 0.5-0.9 g/L, Disocitric acid 3.9-86 mg/L glucose 45.8-65.6 g/L, fructose 48.4-69.9 g/L, potassium 2093-2517 mg/L, phosphorus 93-151 mg/L, calcium 11-149 mg/L, magnesium 21-104 mg/L and sodium 20-128 mg/L in pomegranate juice at 14°.
