| dc.description.abstract | Enriched and local instant fura and non instant local fura samples were analyzed for total aerobic plate count, Bacillus cereus , yeasts and mould count and proximate composition. In addition the three instant fura sample were assessed or storage stability and sensory qualities. The B. cereus isolates obtained were tested for nterotoxigenicity. Bacterial counts obtained ranged from 2.0 x 102 to 7.8 x 103 cells/g germinated instant fura, 3.0 x 103 to 6.5 x 104 cells/g for soybean instant fura and x 103 to 9.7 x 104 cells/g for instant local fura and 2.6 x 103 to 9.3 x 104 cells/g for ion instant fura. B. cereus count ranged from 1.0 x 102 to 2.0 x 103 cells/g for germinated instant fura, 8.0 x 102 to 7.4 x 103 cells/g for soybean instant fura, 1.5 x 103 to 1.9 x 104 cells/g for instant local fura and 1.4 x 103 to 2.0 x 104 cells/g for the non instant local fura. Yeasts and mound counts also ranged from 2.0 x 102 to 2.3 x 104 cells/g for germinated fura, 4.0 x 103 to 2.8 x 104 cells/g for soybean fura, 3.0 x 103 to 3.0 x 104 cells/g for instant local fura while non instant local fura had counts of 3.5 x 103 to 4.0 x 104 cells/g. In all the counts there were no significant difference at 5% level of significance. Soybean fura contained significantly high protein content (9.42%) than the instant local fura (1.60%), germinated fura (1.69%) and non instant local fura (7.20%). The instant local fura had significantly higher aero Die plate counts (6.5 x 104 to 1.0 x 105 cells/g), yeasts and mound counts (2.2 x 103 to 2.5 x 103 cells/g) than the other two fura samples. Germinated fura had higher tit ratable acidity (1.35 to 1.36) than the other two samples. There was no significant difference in the moisture content of the three fura sample at 5% level of significance. Ten (10) of the B. cereus isolates tested for enterotoxin production were toxigenic by the ideal loop test. Five (5) of the isolates (50%) were from local fura, 4(40%) from soybean fura and 1(10%) from germinated fura. In terms of preference, the local fura was more acceptable (61.67%) than the soybean fura (25.92%) and germinated fura (12.35%). There was no significant difference (P 0.05) between the local fura and the enriched samples in odour, texture, smoothness, acidity, sweetness, and over all acceptability. However there was a significant difference (p < 0.05) in colour of germinated fura from those of soybean and local fura while the colours of soybean and local fura were not significantly different. | en_US |
