I want to preserve my cooked food (meat curry) for future use. I have a small retort /autoclave at my place.
My Question are
1)Does the can need to be vaccum sealed before sealing and sterilization?
2)how long the food in a metal can should be kept in retort and at what temperature it has to maintain for a while to kill all the microorganisms
3)lastly how to quality check after the whole process that my food is preserved accurately and have no threat at least 6 months.
Will appreciate promt reply
