Characterising the Essential Microbiota and Nutrient Makeup of Packaged Pasteurised Milk Products While they are Being Stored

Abstract

Microbial communities in pasteurized milk are intricate and influenced by storage and sterilization conditions. Pasteurized dairy products may be highly susceptible to spoilage due to this intricate microflora. High-throughput sequencing was used to identify microorganisms in packaged pasteurized milk products taken from dairy processing factories in China and stored at 0, 4, 10, 15, and 25ºC for 15 days. As a result, the majority of the microbiota was classified into six phyla and 44 genera. In addition, principal component and multi-factor analyses were used to examine the changes in the pasteurized milk's nutritional composition, which included 8 chemical constituents, 7 taste values and 16 free amino acids. Pseudomonas, Aeromonas, Paenibacillus, and Serratia were found to be the core functional microbiota that has a significant impact on the nutritional content of pasteurized milk by Pearson correlation analysis. As a result, the findings provide a comprehensive understanding of pasteurized milk's safety and shelf life when stored. Pasteurized milk is not only one of the most nutritious sources of dairy products, but it is also a complex biological fluid that is an excellent growth medium for many microorganisms
