Determination Selected Engineering Physical And Che M1cal Properties Of Dika Seed (Irvingia Gabonensis):- Echem Okwudirichukwu D

ABSTRACT 'r The study on the determination ofsome selected physical and chemical (functional) properties of Dika seed (/rvingia gahoricnsis) to reduce drudgery in the processing of Dika seed (Irvingia •’ahenensi.s) and it was carried out by using standard procedures. These properties were evaluated at a moisture content of 24.3% (dB). The major, intermediate and minor diameter were found to be 3.23mm, 1.80mm and 0.52mm respectively, the arithmetic mean diameter, geometric mean diameter square mean diameter. EMI) and sphericity of Dika (Jrvingia gaboneiisis') seed arc 0.0069mm, 0.121 mm, 1,7981mm, 0.1563mm, 3.2497mm respectively. The true density, bulk density and aspect ratio of the seed were 0,98g/mm3, 4.60g/mnT and 56.1353mm respectively. The angle of repose for phywood, glass and metal sheet are 55°, 33° and 32° respectively while their corresponding static friction are 0.38, 0.67, and 0.77 respectively. The volume, surface area, one hundred weight of seed were 156.17mm3, 4.7500mm2, 0.6249g respectively. The oil and water absorption capacity of unmiled are 7.00g and 3.00g respectively while, the milled oil and water absorption capacity are 7.20g, and 3.40 respectively. The absorbance and transmittance of unmilled are 0.422ml and 1.153ml respectively, while the absorbance and transmittance of milled are 0.646ml and 1.327ml respectively. The solubility index of unmilled and milled are 1 057mm and 1.097mm respectively. The unmilled and milled Dika {Irvingia gabonensix) seed have gelation temperature and time as 60°C and 30minutes respectively. The information gotten will therefore and in the processing (milling, packing and storing) each varieties.
