What will happen if you put soda on an Apple?
If you dip or soak your apples in baking soda water it’ll make the cut surfaces soften and become unappealingly mushy. Soda can help preserve the fresh color of green vegetables if it’s added to the cooking water, which might be why some cooks assume it’ll preserve the color of fruit as well.
How do you prevent enzymatic browning in apples?
Cooks often put cut apples or potatoes in a water bath until they are ready to be cooked. The water reduces contact with oxygen and prevents enzymatic browning. Cooking fruits or vegetables inactivates (destroys) the PPO enzyme, and enzymatic browning will no longer occur. Refrigeration can slow enzymatic browning.
Can you slice apples ahead of time?
Squeeze as much air as possible out of the bags. Then store the slices in the fridge. I’ve held the apples in the fridge for several days with no browning happening. This is good if you need to do some party prep ahead of time.
What causes apples to brown?
When an apple is cut (or bruised), oxygen is introduced into the injured plant tissue. When oxygen is present in cells, polyphenol oxidase (PPO) enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.
