Hello,
I am looking for some clarity on the difference between hot filling and tunnel pasteurization.
From all of the scholarly articles and research papers I have read, it’s seems that tunnel pasteurization is achieved when the internal temperature of the product at the coldest spot is at 165F and is held there for a period of time.
Hot filling recommendations are that the food or beverage be filled into the jar/bottle at no less than 180F.
I am trying to figure out why there is a 15F difference in process temperature?
Is this because when hot filling the beverage/food it will rapidly lose some heat when it is filled into the cold packaging? Or is this simply a measure of time/temperature/PUs? I’m just confused about why tunnel pasteurization can achieve the same goal with lower temperatures. I have seen no articles that advise hot filling at these temperatures.
Any insight is greatly appreciated.
