The influence of different heat treatments, including oven drying at 40, 50, 60 and 70 \u00b0C for 60, 120 and 180 minutes at each temperature, roasting, boiling for 5, 10, and 15 minutes, sun and solar drying for 480 and 720 minutes, on the drying behaviour, moisture content and oil yield of Balanite aegyptiaca<\/em> kernels (BaKs) was investigated.
\nThe moisture contents on wet basis were determined by the oven drying method at 105 \u00b0C for 4 hours and calculated from both weight loss data and dry solid weight of the kernel samples, while oil was extracted with n-hexane using Soxhlet apparatus. The experiments were conducted in triplicates.
\nLow moisture contents of 2.726 and 2.426 % at drying times of 60 and 120 minutes were obtained in Balanites aegyptiaca <\/em>kernels dried at 70 \u00b0C, while drying at 40, 50 and 60 \u00b0C for 180 minutes gave low moisture contents of 3.973, 3.861 and 3.779 %, respectively. The drying of Balanite aegyptiaca<\/em> kernels occured in the falling rate period. The moisture contents of Balanites aegyptiaca <\/em>kernels oven-dried at 40, 50, 60 and 70 \u00b0C decreased with increasing drying time when compared to the raw kernels. Similarly, the average oil yield of Balanite aegyptiaca <\/em>kernels decreased with increasing temperature in the following order: raw>40 \u00b0C>50 \u00b0C>60 \u00b0C>70 \u00b0C. The highest oil yield (45.345 %) was obtained in the boiled kernels and the least oil yield (37.790 %) in those kernels \u00a0dried at 70 \u00b0C. Results from this study justify the use of boiling in traditional Balanite kernel oil extraction process as it gave the highest oil yield.<\/p>\n<\/td>\n<\/tr>\n
