Membrane Filtration Sampling
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
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
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 Troubleshooting—Following the Water Principle
Clean-in-place troubleshooting often becomes more complicated than it needs to be. When a CIP or assisted cleaning system is not performing as expected, many people often forget the simple basics: if water is pumped into the system, it should follow the intended flow path and come back out. Tracing that path can help teams identify blocked…
Using a Peristaltic Pump for Representative Sampling—FAQs
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
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…
