Where is the concentration of protective antioxidant elements nearly double compared to the inner pulp of an onion?
Answer
The outer peel of the onion.
Scientific analysis detailed in the text reveals a significant disparity in the distribution of protective compounds within the onion structure. Testing explicitly highlights that the outer peel, which is frequently discarded during preparation, holds the highest concentration of these beneficial elements. The antioxidant activity measured in the peel is reported to be nearly double the activity found in the inner, edible pulp of the onion bulb. This suggests that traditional peeling discards the most potent antioxidant reservoir.
