Understanding Hearts of Palm
Hearts of palm are the edible inner core of certain palm trees. The harvesting of hearts of palm is a labor-intensive process. The perishable nature of fresh hearts of palm is why canning or jarring is so common.
During the canning process, harvested palm hearts undergo cleaning and trimming before heat pasteurization. This process ensures the product is safe and extends shelf life. The heat application means the final product is cooked, not raw. Hearts of palm are packed in a brining solution, typically water and salt, which helps preserve them and affects the flavor.
Comparing Canned and Fresh
Fresh hearts of palm have a crispier texture and a delicate flavor. Canned hearts of palm are softer and more tender due to heat processing. The brine also gives canned hearts of palm a tangy flavor not found in fresh versions. Rinsing the canned hearts can reduce the sodium and tang, but not restore the crispness.
Nutritional Information
Both fresh and canned hearts of palm are nutritious, with fiber, protein, and minerals. They are low in fat and carbohydrates. The main nutritional difference is the sodium content. Canned hearts of palm contain more sodium due to the salt brine. Rinsing canned hearts of palm before use is recommended to reduce sodium intake.
