Phenolase, also known as polyphenol oxidase, typically causes browning in apples when they are exposed to air. This enzyme catalyzes the oxidation of phenolic compounds to quinones, which then polymerize to form brown pigments. This browning reaction can affect the visual appeal and perceived freshness of the apples, but it does not significantly alter their taste or nutritional value.
