Preservation techniques that rely on temperature can be successful, but they are not guaranteed to produce foods that are completely microbial-free and may encourage the growth of some microbes under certain conditions. High temperatures used in methods like grilling can produce carcinogenic substances.

Preservation techniques and microbial growth :
b
Impact of high temperatures on food safety :
Key Concept
Preservation techniques and microbial control
Explanation
Preservation methods that use temperature, such as refrigeration or freezing, aim to slow down or halt microbial growth. However, they may not eliminate all microbes, and some can survive or even thrive at specific temperatures. High-temperature methods like grilling can lead to the formation of carcinogenic substances such as polycyclic aromatic hydrocarbons (PAHs) and heterocyclic amines (HCAs).
