Abstract
Tomato products are essential source of some nutrients such as vitamin A, vitamin C, fiber, potassium, and very important herbaceous plant (Solanum lycopersicum L.) in all countries. The objective of the paper was to evaluate microbial analysis in three popularly consumed canned tomato products from the market in Sadat City, Menofya Government, Egypt. The results indicated that the total count ranged from 2.0× 103±0.10 to 9.7×104±0.01.Twelve isolates were isolated and identified as : 6 gram negative bacteria identified as (2 Enterobacter aerogenes; Enterobacter sakazakii; Escherichia coli; Pseudomonas aeruginosa and Pseudomonas fluorescens); 2 gram positive bacteria identified as (B. brevis and B.pasteurii) and 4 cocci identified as Micrococcus sp. Aspergillus flavus; Fusarium oxysporum and Macrophomina phaseolina and Saccharomyces cerevisiae were isolated from canned tomato products. However, the opening of tin tomato products allows easy colonization of fungi and this has health implications on human being, Therefore, tin tomato products should be used immediately after opening.
