AB  - Bambara groundnuts is an indigenous, underutilized African 
  legume grown primarily for its seeds which are eaten fresh when semi ripe as 
  a pulse when dry and mature or ground into a flour. In this study, the experimental 
  dehydration behavior of two different varieties of of bambara groundnuts, Black 
  variety (BB) of moisture content 0.88 g g<SUP>-1</SUP> and White variety (WB) 
  of moisture content 0.90 g g<SUP>-1</SUP> was investigated and the experiments 
  were carried out under isothermal conditions using convection air-forced dryer 
  at 50, 60 and 70&deg;C. The drying data were fitted to the different mathematical 
  models such as Lewis, Henderson and Pabis, Logarithmic and two-term models. 
  The performance of these models was investigated by comparing the determination 
  of coefficient (R<SUP>2</SUP>), reduced Chi-square (&#967;<SUP>2</SUP>) and 
  Standard Estimate Error (SEE) between the observed and predicted moisture ratios. 
  The results obtained showed that the logarithmic and the two term models successfully 
  described the drying behaviour of the seeds. Generally, the moisture diffusivity 
  constants derived from the Fick&#146;s 
  law of diffusion increased with increase in temperature according to the Arrhenius 
  type equation with BB variety exhibiting low values (5.97x10<SUP>-11</SUP> to 
  8.51x10<SUP>-11</SUP> m<SUP>2</SUP> sec<SUP>-1</SUP>) and WB high values (1.44x10<SUP>-11</SUP> 
  to 2.78 x10<SUP>-10 </SUP> m<SUP>2</SUP> sec<SUP>-1</SUP>).
