The Paste (plant origin only & shelf stable) is hot fill in pouch and cool immediately by submerging into cold water tank. Hot fill is a CCP and cooling is an OPRP for the current HACCP plan. There was no time limit for cooling currently where it got question.
There was no regulatory or parameter specification setting on cooling to be done after hot fill while I browse through the internet. If cooling in cold environment necessary, can it be done just by putting at room temperature and let it cool down naturally? If it is necessary, any specific time and temperature?
