98% of that industry AIR-POPS the popcorn.

You see some yellow, and some is white because the flavor and coating is inconsistent. 
This popcorn is packaged in single servings and different flavors.

Garlic Parmesan, White Cheddar or my personal favorite Kettle Korn. All flavors are tasty and full of th Omega proteins created by the KETTLE process.
KETTLE - before it is popped - sprays on PROTEIN because Kernels are 
coated in Sunflower Oil. Omega 3 and 6.
