For those that need and want a non-browning apple I have two words for you: OPAL APPLE. This Non GMO Project verified apple was naturally cross breed with a Golden Delicious and Topaz apple. The result, an apple with great flavor and the ability to naturally resist browning for several days.
Opal apples look bright yellow with occasional faint hints of red or green. The Opal apples will have a sticker on them with the name on it.
Why do we need a GMO non browning Apple if one can be created naturally through breeding?
