Question: We produced coconut milk in cans!. Cans after sterilization in the retort comes out dented for unknown reason!.!?
the coconut milk we produced becomes dented after sterilization in the retort with counter pressure from 0!.
5 to 1!.8 bars with total sterilizing time of 50 mins!. The fat matter content of our coconut milk is 22%!. However, there are times that we get good results, that is when we use reduced steam pressure of 70 psi!. Is the reduced steam pressure affecting the integrity of the cans!?Www@FoodAQ@Com

The higher pressure is obviously exceeding the structural stress limits of the cans, but if they remain sealed, then the integrity is preserved!. The lower pressure is not affecting integrity!. A lab check would tell you if you need a bit more time in the retort at the lower pressure, but 70psi certainly would seem to be adequate!.Www@FoodAQ@Com

seems the quality of the cans are not fit for it!. Try using a higher quality of materials for the cans, or even tetra-pack which i've heard is really good for liquids,Www@FoodAQ@Com

wtf!? lolWww@FoodAQ@Com
