ABSTRACT

This study evaluated the protein fatty acid and mineral changes in sweet potato root iheal inoculated with two selected fungi by solid state fermentation procedure. The total protein content was raised from 4.95% to 11.83% and 6.69% within 48 hrs for Aspergillus oryzae and Aspergillus niger respectively. The total lipid dropped from 1.93% in thè control to 1.36 and 4.19% for A. niger and A. oryzae respectively. The fatty acids 0 6 : 0 and 0 8 :2 were preponderant over other fatty acids with A. niger and A. oryzae recording 18.94 and 28.17% for 0 6 :0 and 43.20 and 37.88% for 0 8 :2 respectively. The ash content values were 3.53% for thè control, 3.54 and 4.51% for A niger and .4. oryzae respectively. The mineral changes analysed were for Calcium. Potassium, Iran. Manganese, Sodium, Zinc and Phosphorus. The pK changed from 5.26 for thè control to 3.80 and 5.39 for A: niger and A oryzae respectively.
