Explanation

Amanda Theodosia Jones, an American inventor, patented the vacuum-packed canning process in 1873. Her innovation involved using a vacuum to remove air from containers before sealing them, which significantly improved food preservation by reducing bacterial growth. This technique laid groundwork for modern vacuum-sealing food storage methods. Katherine Blodgett invented non-reflective glass, while Alice Parker invented a gas-powered heating furnace.
