Chemical Characterisation of the Fruit of Black Chokeberry Grown on Different Types of Soil

Plant samples were collected in March 2012 using the sampling method defined in (ISO 10381: 3, 2001), and delivered to the Laboratory, of Faculty of Agronomy, from Caeak for analysis. Black chokeberry was grown on four types of soil viz. Luvisol, Pseudogley, Fluvisol and Vertisol. The total sugar content was highest in black chokeberry fruits sampled from the Vertisol, followed by those grown on Luvisol, Fluvisol and Pseudogley soils. Black chokeberries were found to contain sorbitol, a sugar alcohol, which is not a characteristic common to other berries. The dominating organic acids in black chokeberry fruits include malic acid and citric acid, regardless of soil type. The fruits are rich in vitamin C content – 0.2 g/L, irrespective of soil type.
