Butyric acid, along with acetic acid, can be reacted with cellulose to produce the organic ester cellulose acetate butyrate (CAB), which is used in a wide variety of tools, parts, and coatings and is more resistant to degradation than cellulose acetate.
One and a half hours is much too long to cook the chicken at 350 degrees F. The time your chicken will bake in the oven does depend on the internal temperature and the size of your chicken or chicken pieces. Generally I bake chicken at 350 degrees F. for 30 to 40 minutes.
A safe temp for pork is 160 degrees. The roast should be pulled from the oven when it reaches 150 to 155 degrees because you have to account for carry over cooking. The roast will continue to cook when you let it sit for ten minutes outside of the oven. The meat might be a little pink but it is completely safe to eat.
