Pineapple is one of the most economically important fruit crops of Mauritius and is often sold after being minimally processed (MP). Unfortunately, minimally processed whole (MPW) and fresh-cut (MPC) pineapples are susceptible to microbial contamination that can compromise the quality of the products. It is therefore important that MP pineapples have optimal freshness, nutritional quality, and are free from microbial contamination which would otherwise constitute a public health hazard to the consumers.The main aim of this study was to assess the microbiological, nutritional, and physicochemical quality of MP pineapples sourced from wet markets and supermarkets. Samples of MPW and MPC pineapples collected from open markets and supermarkets were subjected to microbiological, pH, and vitamin C analyses. The MP pineapples were also challenged using the specific spoilage organism (SSO), Pseudomonas fluorescens and subsequently stored at either ambient or refrigeration temperature to simulate storage conditions of wet markets and supermarkets, respectively. Laboratory analyses revealed that the Total Viable Counts (TVC), pH, and vitamin C content for MPW and MPC pineapples sampled ranged from 4.8 – 5.5 Log CFU/g, 4.16 – 4.96, and 21.60 – 28.90 mg/100 g, respectively. Since the population density of TVC was less than 7 Log CFU/g, which usually marks the onset of microbiological spoilage, the products were considered to be of a satisfactory microbiological quality. Moreover, there was no statistically significant difference in the microbiological load, pH, and vitamin C content for pineapples sourced from markets and supermarkets. Taken together, this study reveals that MP pineapples sold in wet markets and supermarkets have a satisfactory microbiological, nutritional, and sensorial quality with a shelf-life of &gt;7 hours and &gt;5 days when stored at room (29°C) and refrigeration (4°C) temperatures, respectively.
