- Pasteurization brought significant change especially for preserving juice and milk, as it kills microbes by applying heat without affecting the nutrition and taste of the food. 
These processes made significant advancements to the long-term food preservation that we have now. The tin cans also helped soldiers during WWI as they are cheap, long-lasting, and transportable. ]]> 2022-05-16 15:52:33 UTC https://padlet.com/melaniayoo/e1q91h5zz42f4wtd/wish/2185976956 20th Century: Developments (1) melaniayoo https://padlet.com/melaniayoo/e1q91h5zz42f4wtd/wish/2185996054 Preservation Methods:
