Abstract

Ugba’ and ‘Ogiri’, fermented products of African oil bean (Pentaclethra macrophylla) and Castor oil seed (Ricinus communis), were screened for microbiological profile and ability to serve as carrier medium for probiotic, the sensory acceptability of products over twenty one days storage was also analyzed. Assay of unpasteurized products from different food vendors gave mean heterotrophic bacterial count for Ugba ranging from 6.20 x1010-2.96x1011 cfu/g, bacteria count in Ogiri samples range from 5.10x1010-1.21x1011 cfu/g. Mean fungal count in Ugba samples range from 8.0x108-2.01x1010 cfu/g while count of fungi in Ogiri range from 2.1x109-1.21x1010 cfu/g. The bacteria isolated in-clude species of Bacillus, Staphylococcus, Enterococcus, Serratia, Klebsiella, Micrococcus, Pseudomonas, Streptococcus and Lactobacillus. The fungi species implicated include Rhizopus, Geotrichum, Saccharomyces, Mucor, Penicillium, Fusarium and Aspergillus. Microbial load of inoculated LAB (LASO and LAWB) multiplied in all the products throughout the storage period, there was also increase in number of recov-ered LAB from the stool samples through the period of study. Unpasteurized products of both Ugba and Ogiri declined in sensory attributes after day 5-9 while Ogiri and Ugba samples with LASO and LASO+LAWB combinations had better sensory properties at day 21. Ogiri and Ugba could serve as good carrier medium for probiotic with good organoleptic properties, however texture stability of these products during storage need further investigation. Hazard Analysis Critical Control Point assessment, Good Manufacturing Practice and packaging are nec-essary to curtail microbial contaminations in these products.
