The role of microbes in cream quality and safety: A comprehensive overview
Authors

Abstract

Cream, a fat-rich dairy product, is inherently susceptible to microbial contamination and subsequent spoilage due to its nutrient-rich composition and water activity. This abstract summarizes the diverse microbial ecology of cream, tracing the primary sources of contamination from raw milk, processing environments, and handling practices. Key microbial groups, including psychrotrophic bacteria (e.g., Pseudomonas), mesophilic bacteria (including lactic acid bacteria), coliforms, spore-formers (Bacillus, Clostridium), and potential pathogens (Staphylococcus aureus, Salmonella, Listeria monocytogenes), are highlighted alongside their roles in various spoilage mechanisms such as souring, rancidity, bitterness, and textural defects. The critical role of pasteurization in ensuring safety and extending shelf life is discussed, contrasting different heat treatment methods (LTLT, HTST, UP, UHT). Finally, essential strategies for microbiological control throughout the production chain, encompassing raw milk quality, hygienic processing, effective pasteurization, prevention of post-processing contamination, and proper storage, are emphasized as crucial for delivering safe and high-quality cream to consumers. Understanding and managing the microbial landscape of cream is paramount for the dairy industry to mitigate spoilage and safeguard public health.
