Question 1

What is the critical control point (CCP) in milk pasteurisation?

Accepted Answer

In HTST milk pasteurisation, the critical control point (CCP) is the pasteurisation temperature and hold time combination. The pasteuriser must heat milk to at least 72°C (161.6°F) for at least 15 seconds in continuous HTST pasteurisation. The flow diversion valve (FDV) is the critical piece of equipment — it continuously monitors the product temperature at the holding tube exit and automatically diverts the product back to the raw milk balance tank if the pasteurisation temperature falls below the setpoint. Temperature recorder charts from the pasteuriser are legal records that must be retained. Regular calibration and validation of the temperature sensors and the FDV is required under HACCP and most dairy regulatory frameworks.

Question 2

What packaging format should I choose for my pasteurised milk line?

Accepted Answer

The choice of packaging format for pasteurised milk depends on the target market, the cold chain infrastructure, the production volume, and capital budget. Gable-top carton fillers produce premium-image packaging familiar in many markets, but require carton blanks from a paper-based packaging supplier. HDPE bottle blowing and filling lines produce the robust plastic bottles dominant in many developing market retail channels. Polythene sachet fillers (form-fill-seal machines filling milk in thin plastic pouches) have very low packaging material cost and are widely used in sub-Saharan Africa and South Asia for mass-market affordable milk. Each format has different capital cost, operating cost, and consumer perception trade-offs — validate your target consumer's preferred format before specifying the filling line.
