Membrane Filtration Sampling

ByChris Pundmann

Membrane filtration is a widely used process in the dairy industry that separates specific components of milk and whey and then either concentrates or removes/reduces them. The technology used in cheese-making, whey protein concentration, fractionation of protein, and numerous other dairy processes requires special sampling considerations for both regulatory purposes and component analysis. It is…

Prevalence of Cold-tolerant Spore-forming Bacteria in the Milk Supply 

ByClarence Johnson

The shelf life of pasteurized fluid milk is challenged by bacterial contamination that enters the finished milk supply through two portals: a) contamination by Gram-negative psychrotrophic bacteria during processing after pasteurization; and b) contamination by Gram-positive spore-forming bacteria that enter primarily through the raw milk supply. In today’s processing environment, where post-pasteurization contamination is largely…

Raw Milk String Sampling to Help Increase Feed Ration Efficiency

ByDr. Kraig Peel

Raw milk string sampling has become increasingly important. This post examines the potential value of string sampling of milk to help nutritionists fine-tune ruminant formulations to provide better information and manage costs. Current feed market prices have milk producers looking for every possible way to manage costs, making the role of ruminant nutritionists increasingly important. We scrutinize…

Clean-in-Place (CIP) Troubleshooting—Following the Water Principle

ByRick Rector

When troubleshooting clean-in-place (CIP) or assisted cleaning system (ACS) cleaned processes, often, many people forget the simple basics: If you pump it in, it should come out. The Following the Water Principle is just that, as shown below in a single pass CIP/ACS system. A clean-in-place checklist Note to self, check for water! Staying true…

Using a Peristaltic Pump for Representative Sampling—FAQs

ByDan Funke

A peristaltic pump is commonly used to collect a representative milk sample by farmers and veterinarians. There are several reasons to use QualiTru’s sampling system for collecting representative composite samples of milk. These include: In this post, I’ll go over some of our new customers’ frequently asked questions (FAQs) about using a peristaltic pump for…

Lab Pasteurized Count for Estimating Bacteria in Raw Milk

ByDan Funke

The Lab Pasteurized Count (LPC) estimates the number of bacteria in a raw milk sample that can survive the pasteurization process. Most bacteria are destroyed by pasteurization. However, certain types are not. (Source: Journal of Dairy Science 92(10):4978-87) Lab Pasteurized Count test determines bacteria that are not natural Raw milk can be contaminated by various…

Post-Pasteurization Contamination Monitoring: A Canary in the Coal Mine

ByDarrell Bigalke

Post-pasteurization contamination in dairy plants is a warning signal for potential food safety and spoilage concerns. While having an effective sanitation program gets the most attention, good sanitation alone cannot guarantee product quality and food safety. Sampling and testing products during processing are critical for identifying potential sources of post-pasteurization contamination. Possible causes of post-pasteurization…

String Sampling RE-Imagined for Milk Quality and Much More…

ByDan Funke

String sampling has traditionally been an affordable and reliable method for monitoring milk quality and udder health on commercial dairy farms. While that application is the most widely used, string sampling offers much more. Do you want to improve efficiency and better manage costs? Other farm applications can benefit significantly by adapting QualiTru’s string sampling…

Standard Plate Count of Milk: Effects on Quality

ByDan Funke

Standard Plate Count (SPC) directly impacts the quality of raw milk. The quality of the raw milk supply begins on the dairy farm and ends when the product is consumed by consumers. Maintaining the highest quality throughout this chain requires close monitoring and numerous regulations and quality standards for Grade “A” raw milk. SPC measures…
