Red Leaf Lettuce: Naturally has red pigments and may show intensified pink or red coloration due to the same enzymatic processes.
Butterhead and Romaine: Generally less prone to pinking but can show browning due to oxidation.
Use of Acidic Wash: Washing lettuce in diluted lemon juice or vinegar can slow enzymatic browning and pinking by lowering pH.
