Yes, canned yams are fully cooked and ready to eat right out of the can. Canning is a preservation process that involves cooking food to a high enough temperature to kill any bacteria before sealing in an airtight container. This makes canned yams shelf-stable at room temperature until the can is opened.
Cooking Process for Canned Yams
Here is a quick overview of how canned yams are prepared:
- Yams are washed, peeled, and cut into pieces.
- The yam pieces are then cooked by boiling, steaming, or baking until fork tender.
- After cooking, the yams are placed into cans along with liquid (typically water or syrup).
- The cans are then sealed and heat processed at temperatures above 212°F, typically 240-250°F, for a set period of time to kill any bacteria.
- The high heat processing cooks the yams fully and creates an airtight seal.
- The cans are then cooled, labeled, and ready for distribution and sale.
So in summary, the canning process involves thoroughly cooking the yams before sealing them in the can. All canned yams are fully cooked when you purchase them at the grocery store.
