The link between clean raw milk and product quality

Researchers at Cornell University offer a perspective on producer premium programs. They find that premiums for raw milk quality may deliver financial benefits to dairy processors.

A number of tests have been used traditionally to evaluate the quality of raw milk, including, but not limited to, somatic cell counts (SCC), different types of bacterial counts including the standard plate count (SPC) and tests for the presence of drug residues and added water.

ON DEMAND: Deposit formation by biopolymers such as proteins or polysaccharides on membranes causes significant reductions in flux and transmission of components, irrespective of reverse osmosis, nano-, ultra- or microfiltration applications. Crossflow conditions are meant to minimize deposit formation, but cannot prevent the deposition of material sufficiently. Part of the reason is the inconsistent transmembrane pressure along the flow path across a membrane module with a high transmembrane pressure at the module inlet and a gradient towards lower pressures towards the module exit.

ON DEMAND: Membrane programs in the age of FSMA require increased vigilance to maintain the safe production of food products. Under FSMA a company must do a risk based analysis to identify potential hazards. Within the new Food Safety Plan, preventive controls must be in place to manage those risks.
