microencapsulated flavors with varied thickness walls could gradually release flavor at .5 to 3 seconds, with the effect that the flavored pea crisps you are eating actually get more and more delicious, rather than it all being in the first bite. It might take longer to eat food, reducing total calorie intake. The little, varied thickness wall microcapsules could be made of lecithin or choline, so be slightly good for people.-- beanangel, May 22 2017random, halfbakery
