| We assessed the degree of freshness of gutted and ungutted red tilapia (Oreochromis ssp) using physicochemical and microbiological analyses of samples of gutted red tilapia on days 0, 3, 5, 8, 11, 14 and 17 and of ungutted red tilapia on days 0, 3, 6, 9, 11, 14 and 16. The total sample size was five fish stored in ice at temperatures between 0 and 4 °C. Different methods were used to study the degree of freshness: pH, water holding capacity (WHC) and microbiological analysis (aerobic mesophilic count). Once we obtained the results, a one-way analysis of variance (ANOVA) was used to determine possible correlations between the values of deterioration and the data obtained by other analysis methods. The one-way ANOVA showed that statistically significant... |

| The objective of this study was to evaluate the applicability of the Petrifilm™ plates to enumerate microbial groups in sheep milk. Samples of sheep milk (n = 30) were plated simultaneously, to enumerate mesophilic aerobes, total coliforms, lactic acid bacteria, Staphylococcus aureus and Escherichia coli, using convencional reference protocols and Petrifilm™ plates. The results were compared using McNemar's test, linear regression and ANOVA (p < 0,05). The results demonstrated good significant between conventional methodologies and Petrifilm™ plates. Further, the Petrifim™ STX for counting S. aureus had higher recoverability of bacteria compared with the conventional methodology. Based on the results obtained and in view of the ease and rapidity... |
