Amanda Jones - Vacuum packed
The proper storage of food to achieve better preservation has been something for which humans have devised numerous methods throughout history: salting, cold, drying, smoking, are some of them. Nothing like the revolution brought about by the invention of the can of preserves. However, Amanda Theodosia Jones went further. In the 19th century, she managed to eliminate the air from a can, thus inventing vacuum packaging without prior cooking of preserved food, thus improving its quality at the time of consumption. Her invention was patented in 1873 under the name "the Jones process."
