natural spices.
____ 11. Sodium lactate may be used in processed meats to control mold growth.
____ 12. High pressure processing (HPP) is a novel processing technology that inactivates

____ 15. The cooking rate at the beginning of a cooking process for a meat product is
typically controlled by the wet bulb temperature.
____ 16. An ideal air temperature (dry bulb) in a smokehouse for maximizing smoke
