SUMMARY:

The objective was to evaluate the resistance to contamination by microorganisms with the addition of the fruit of pink pepper (Schinus terebinthifolius raddi) in Cottage cheese formulated with bovine. The cheese came with five: T1 - Pink Pepper Cottage; T2 - Cottage cheese with (0.5%) pink pepper, T3 - Cottage cheese with (1%) pink pepper, T4 - Cottage cheese with (1.5%) pink pepper and T5 - Cottage cheese with (2%) of pink pepper. For this, bacterial strains of Staphylococcus aureus and Escherichia coli were inoculated in the proportion of 300 µg/150g of cheese in each of the treatments. The samples were constituted by their conservation capacity at three times (0, 3 and 7 days) and their chemical composition (moisture, ash, lactose, titratable, protein and physical lipids). The alternatives were performed and had as means and their related relatives in duplicates. For physical-chemical determinations, all determinations were made in triplicate, using the Analysis of Variance (One-Way) model, followed by the Tukey test, at a minimum significance level of 0.05. All treatments, with the exception of 0%, were efficient for cheese conservation. The 2% being the most efficient against the growth of S. aureus and the 1.5% and 2% the most efficient against the growth of E. coli, characterizing the condiment as useful for the functionality of the shelf life of these products. All physico-chemical variables are all affected, but remain in compliance with current legislation.
