Milk age validation

Abstract

The Ministry of Primary Industries (MPI) new regulation serves the purpose of reducing the maximum age of raw milk used in the manufacture of infant formula, with the aim of limiting the deterioration of nutritional components of the materials used during the production of infant formula. MPI states that; immediately before heat treatment (pasteurisation), raw milk used to manufacture the relevant product (infant formula) must be no older than: the age specified and validated in the Risk Management Programme (RMP); or if no age is specified, 72 hours. The purpose of this project will be to devise a way to validate that the raw milk used within SML process is of a quality that meets all external and internal requirements, and to propose a maximum milk age to be stated within the RMP. This will fully satisfy all aspects of the regulation and will allow milk to exceed 72 hours of age prior to pasteurisation. The Milk Age Validation project is composed of two parts that are tied together through a recent regulation released by MPI, being; Milk Quality Validation - Ensuring that the quality of raw milk used in PIF does not deteriorate during the manufacturing process. Milk Age Traceability-The ability to accurately trace the age of raw milk, and the processing steps the milk has been subjected to.
