The addition of modified milk fat stimulates a progressive release of free fatty acids via lipase action which is essential for rapid flavor development in blue cheese. The metabolism of the blue mold further breaks down fatty acids to form ketones to give blue cheese a richer flavour and aroma.[25]. The cheese's signature blue veins are created during the early aging stage when the cheese is "spiked" with stainless steel rods to let oxygen circulate and encourage the growth of the mold.
