Abstract

Pineapple is one of the most economic importance tropical fruits beside mango, papaya and avocado. The consumption is predicted to be increased in the near future and hence demand for continuous supply of the fruit is of major interest. Pineapple is also high in nutrition compositions and is a best source of Vitamin C. Vitamin C is an antioxidant and a continuous consumption of pineapple fruit could promote human health. The main objectives of this study are to determine the Vitamin C concentration in pineapple fruit and make comparison based on the concentration between selected cultivars. The second aim is to investigate the soil type composition on the production of Vitamin C in pineapples. Fruit samples are identified and quantified for the amount of Vitamin C over soil type variation to identify the relationship between environmental variation and fruit quality. Vitamin C in pineapplesfruit is determined by using Redox Titration. In soil analysis; x-ray , fluorescence (XRF) Spectrometer Machine was used to determine the compositions that are present in the two type of soil samples: peat and mineral soils. Results indicates each pineapple cultivar display different of Vitamin C concentrations. Secondly, soil composition such as, Silicon dioxide (SOz), Sulfur trioxide (SO3), Calcium oxide (CaO), Iron Oxide (FezO3), Zirconium Dioxide (Zr02), Aluminium oxide (Ar2o3)C, hloride (CI),P otassium oxide (K20)P,h osphorus pentoxide (P205) and Magnesium oxide (MgO) have correlation with the concentration produced.
