Hello Everyone,
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

Hi talhakhan,

 

Welcome to the IFSQN forums.

 

You might find some useful guidance here: USDA Complete Guide to Home Canning

 

Kind regards,

Thanks Tom.
After going through the article I have still confused on one thing.
That for how much time I have to keep my food in the pressure canner at 250F?
The article suggest to keep in 75-90 mins for beef curry thats seems so long
As the food I require to pack is fully cooked and ready to eat
Does it still need to be keep there for the above mentioned time or some more less?

6 months at least

 

Maybe easier to freeze it and reheat.


Kind Regards,
