Abstract


Three samples of different kinds of white garri were purchased from, Mushin, Shomolu and Yaba market in Lagos. A reference sample of garri was produced in Yaba College of Technology processing Laboratory. The samples were coded as AOU, BRT, CBN and REF (for the reference). Proximate analysis showed that moisture content ranged between 8-10%, carbohydrate 87-85%, protein 1-3%, fats content 0.5-0.7%, crude fibre 0.5-0.8%, ash content 1-3%. The physiochemical properties of the samples showed that bulk density varied between 0.5glml-0.69glml, pH values 6.4-6.6. A significant differences in the swelling behaviour of the garri sample was observed at room temperature (28+ 20C) particularly in the first 30 minutes of exposure to water. Water absorption varied between 10-13.7%. The sensory evaluation studies revealed preference for Ijebu  garri (BRT) over others in terms of desirable attributes of taste, aroma, mouth feel and over all acceptability. While the Cotonou garri (CBN) was preferred in terms of yield and pasting quality alone. The hydrogen  cyanide content of all these sample were found to be below (5.4-10.2mg/kgHCN) and fell within the tolerable limits of (10 -15mg/kg HCN) as stipulate by National Agency for food Drug Administration and control (NAFDAC) in Nigeria.

KEY WORDS: Cassava, Garri, proximate analysis, organoleptic, bulk density.
