Abstract :Some moisture influenced physical and gravimetric properties of Ackee apple seeds insert ignore into journalissuearticles values(Blighia sapida); were investigated at 11.9, 17, 22, 27 and 32% moisture content insert ignore into journalissuearticles values(wet basis);. These properties are vital in handling, storing, and processing of seeds including the design of required equipment. Ackee seeds have medicinal and industrial benefits. The seeds were collected from Lanlate, Oyo State insert ignore into journalissuearticles values(7° 36ʹ 0ʺ North, 3° 27ʹ 0ʺ East);, Nigeria where ackee trees are predominant. Seed moisture content was determined using ASAE standard. ANOVA, using Genstat Discovery Edition 4 was adopted for data analysis and means were separated using LSD at 5% significance level. As seed moisture content increased from 11.9 to 32%, there was no statistically significant effect on the seed axial dimensions, principal diameters, sphericity and surface area. This is because seed axial dimensions relatively determine other properties afore stated. However there were significant and linear increases in thousand unit mass insert ignore into journalissuearticles values(189.3 – 230.3 g);, bulk insert ignore into journalissuearticles values(377.0 - 418.3 kgm-3); and true insert ignore into journalissuearticles values(714.3 - 771.1 kgm-3); densities but decrease in porosity was not significant. Increase in both bulk and true densities is due to the rate of increase in the mass of the seed bulk being higher than that of its volume. A non-linear decrease showed in seed volume insert ignore into journalissuearticles values(3.4-3.2 cm3);. Regression equations were generated to predict the behavior of Ackee seeds with respect to their moisture content and a baseline data necessary for the design of equipment for handling, storing and processing Ackee apple seeds was developed. Mechanizing the process line for ackee seeds is therefore possible.
