Abstract

With the aim of verifying the safety for the health of consumers of fruit pulp sold in the city of Campina Grande, microbiological analysis were carried out and the hydrogen ion potential (pH) was verified. Pineapple, acerola, cashew, guava, passion fruit, mango, and strawberry pulps of 3 different brands were purchased in supermarkets and taken to the laboratory for analysis. The analysis of Escherichia coli was performed by the test of multiple tubes determining, the quantification of molds and yeasts was determined by plating on the surface (spread plate) and to verify the presence or absence of Salmonella in the sample, the compact dry Salmonella SL® kit was used . All samples were within the standard established by RDC No. 724, of July 1, 2022 and IN No. 161, July 1, 2022 of the National Health Surveillance Agency for E. coli counts, absence of Salmonella sp and quantification of molds and yeasts .
