Physico-chemical quality of seeds of pomegranate cultivars (Punica granatum L.) grown in Iran and antioxidative activity of their phenolic component.

摘要

Physicochemical properties and antioxidative activity of oils from pomegranate seeds were investigated. 10 pomegranate cultivars were tested. The most abundant minerals were Mg, K and Na. Amounts of ash, protein and phenols present were 1.8-2.3, 6.6-13 and 0.2-1.0%, respectively. Contents of moisture and volatile matter were in the ranges 0.25-0.4 and 0.10-0.19%, respectively. The oil with the highest phenols content (from var. Poste Seia) was able to retard the oxidative deterioration of soybean oil at 60 degrees C, in a dose dependent manner at concn. in the range 100-350 ppm.
