How can I modify my hot sauce to make it Shelf Stable?
Low acid products must be pressure canned. Products intended for sale must be canned in FDA registered facilities and typically inspected by a state regulator. Many areas still have community canneries with some being FDA registered and state inspected where you can prepare your product with equipment that is well suited to the task. These community canneries have staff on hand who can teach you how to use the equipment and offer pointers while helping you adhere to any applicable regulations. The best way to locate nearby community canneries is to contact your local county extension office or university agricultural extension / food science program.
