Effects of High UHT Milk Packing Temperature
Hello everyone
I have a question regarding UHT milk packing temperature, It need to be filled in ambient temperature 20 C, if it become high what are the effects?
Hi Yasas,

Welcome to the IFSQN forums
Higher filling temperatures can result in deterioration of the product and a reduced shelf life particularly if the product continues to be stored at elevated temperatures. You should aim to reduce the temperature after filling if you do find product temperature to be high. See article below.
'Storage at 30 and 37 °C considerably decreased the shelf-life of UHT milk to 16–20 weeks, whereby changes in sediment formation, taste and colour were the limiting factors.'
There might also be issues with the growth of spore formers that have survived the process.
Kind regards,
Tony
