Psychrotrophic Bacteria in Pasteurized Milk: Spoilage, Testing, and Line Sampling
Psychrotrophic bacteria can grow at refrigeration temperatures and contribute to premature spoilage, shortened shelf life, and quality defects in pasteurized milk. Some originate from post-pasteurization contamination, while others may survive pasteurization as thermoduric organisms. Identifying the bacterial group and sampling at strategic points within the process can help dairy processors narrow down potential contamination sources. Bacteria…
