ABSTRACT

Microbiological and Nutritional qualities of avocado fruit sold in Umuahia were carried out.The mean counts of the microorganisms isolated from the avocado samples ranged as follows; total aerobic bacterial plate count, 8.0±0.2x10cfu/g to 2.1±0.2x10cfu/g; Coliform count, 0.00±0.00cfu/g to 1 .6±0.2x 1 0cfu/g; Staphylococcus count, 4.0±0.2x10cfu/g to I .0±0.2x 10cfu/g and the Fungal count, 6.0±0.2xl0 3 cfu/g to 1.35±0.2x 10cfu/g.The bacteria were Erwinia species (36%), Streptococcus species (16%), E.coli (8%), Staphylococcus species (24%), Pseudomonas species (12%) and Chromobacterium species ( 4%) which has the lowest percentage occurence, Erwinia, Pseudomonas and Chromobacterium species were found to be absent in the control (unriped). The fungi isolated were 4spergillus species (40.91%), Penicillum species (27.27%), Fusarium species (18.18%) and Rhizopus species (13.64%).The Proximate analysis was also carried out and the parameters examined ranged as follows; moisture, 65.8710.04% to 75.87±0.04%; total ash,0.47±0.02% to 0.66±0.02%; crude Protein,2. 79±0.01% to 3.43±0.02%; fat,12.67±0.09% to 12.79±0.01%; crude fibre,1.37±0.03% to 1.68±0.00% and carbohydrate,6.67±0.11% to 15.445±0.17%. The vitamin contents were also carried out and their mean values ranged as follows;vitaminA,124.87±0.09mg/100g to 153.765±0.19mg/1 00g; vitamin3,,0.029±0.004mg/100g to 0.069±0.00mg/100g; vitamin3,,0.08±0.00mg/l00g to 0.15±0.01mg/100g; vitaminB,,1.28±0.02mg/l00g to 1.58±0.02mg/100g; vitaminc6.45±0.00mg/100g to 12.82±0.03mg/1 00g and vitamin E,1.87±0.04mg/100g to 2.46±0.02mg/100g. For the minerals, the parameters examined ranged as follows; calcium,l I.94±0.00mg/lO0g to 16.69±0.0lmg/IO0g; magnesium,27.715±0.12mg/100g to 34.55±0.00mg/1 00g; sodium,8.60±0.00mg/l 00g to l l.5 1 5±0.007mg/l00g: potassium,15.710±0.14mg/100g to 21.635±0.2mg/100g; iron,0.455±0.007mg/l00g to 0.830±0.00mg/1 OOg and zinc,0.525±0.07mg/100g to 0.580±0.02mg/100g. From the experiment, it was deduced that there was much microbial count on the deteriorated avocado sample as a result of its high moisture content which enables the growth of microorganisms. The statistical analysis (ANOVA) carried out on the proximate, vitamin and mineral analysis showed that there was a significant difference (P <0.05) among the three samples examined and from this, it was concluded that the riped avocado sample has the highest nutritional content.
