Bacterial generation times—the period it takes for bacteria to double in population—have a significant impact on the quality of fluid milk and its shelf life regardless of the source of microbial contamination. While many factors can lower the quality of fluid milk and reduce shelf life, the most significant is microbial spoilage, making it essential to…
How does representative sampling solve two crucial problems for dairy farmers? Recently, I had the opportunity to have an in-depth conversation with Denise Sutton, Large Farm Sales Manager at DFA Farm Supplies. She has extensive experience in the dairy farm industry, including being a herd manager and running a dairy farm. Denise is also a…
An aseptic sampling system is critical for the quality control process in the liquid food industry. One of QualiTru’s customers in the yeast-fermented beverage business (Brewery) had a specific problem they were facing. Customer problem: Inconsistent results from quality samples Of course, our team took on the challenge of solving the vexing problem of inconsistent…
Biofilms in the dairy processing industry are a big problem because they threaten the quality and safety of dairy products. The growth of bacterial biofilms is the primary reason for microbial contamination of milk and other dairy products. “In recent years, the formation and impacts of biofilms on dairy manufacturing have been studied extensively, from…
Heat-Resistant Psychrotrophic Bacteria or Heat-Resistant Psychrotrophs (HRP) can affect the quality of pasteurized milk. Have you ever poured milk from a carton only to see it come out in chunks? Have you ever gulped milk only to realize too late that it tastes awful? Milk curdling and off-flavors in pasteurized fluid milk are huge turnoffs…
Maintaining the quality of pasteurized fluid milk is essential for consumer safety, shelf life, and product satisfaction. While pasteurization eliminates harmful pathogens, other factors, such as microbial contamination and post-pasteurization risks, can compromise milk quality. By implementing robust quality control measures, including regular sampling and testing, dairy plants can help ensure the safety and consistency…
Someone told me that you need to do something that scares you every day. While I understand the logic, I like to believe that you need to surround yourself with people who challenge you every day. Working in an industry that some may describe as being slow to change can be challenging at times. However, my…
I trust we all know HACCP. HACCP and me go back a long way; as a matter of fact, we were conceived in the same year! When I came across HACCP during my student years, I thought it was really boring; HACCP being methodical, slow and elaborate and me being young and restless. However these…
I’m guessing that many of you reading this blog might agree that a new language has developed while living through a global pandemic. Many of us would also likely agree that referring to the ‘new normal’ is becoming just tiring. But, what exactly does a ‘new normal’ really mean? For many of us, it means…
If we trust the sampling and testing process, we are more confident in the result and can make informed decisions. During the latter part of my career, I ended up in food safety and quality roles. I occasionally faced the dreaded phone call from the laboratory with the message, “We found X!” X was, of course, a food…
