Easily enough there are only two methods to properly can you products. As discussed earlier it depends upon the pH of the specific food being canned.
Boiling Water Canner:
High Acid foods are processed in a boiling water canner. The heat is transferred to the product by the boiling water which completely surrounds the jar and the two piece cap. As the temperature reaches 212 F not only does it kill the molds, yeasts and some bacteria it also inactivates enzymes.
Very important that you do not use this process for low acid foods because it will produce botulism which could kill you.
Steam Pressure Method:
Low Acid foods must be processed in a steam pressure canner because it allows everything to be heated to 240 F and this kills all bacteria, their spores and the nasty toxins they produce.Do follow the directions and never wander off because a few pounds of difference could ruin the process.
Altitude adjustments may be necessary due to anything above 1,00 feet above sea level causes Barometric pressure to be reduced, affecting the point at which water boils.
Boiling Water Canner
1,001 to 3,000 increase 5 minutes
3,001 to 6,000 increase 10 minutes
6,001 to 8,000 increase 15 minutes
8,001 to 10,000 increase 20 minutes
Steam pressure Weighted gauge dial gauge
0 to 1,000 10 11
1,001 to 2,000 15 11
2,001 to 4,000 15 12
4,001 to 6,000 15 13
6,001 to 8,000 15 14
8,001 to 10,000 15 15
See that's not too hard and there's nothing better than doing things right to achieve fantastic results. Next time we will talk about all of the equipment needed, so until then remember, What " Can " you do..
