What You Need to Know
These techniques relied on creating hostile environments for spoilage microbes: high salt concentrations induced osmotic pressure, acidic pH from lactic or acetic acids inhibited growth, and elevated temperatures from drying or smoking denatured enzymes and deposited antimicrobial phenolics. The interplay of temperature, moisture, and pH controlled microbial viability while retaining nutrients.
The Science
Primary Reaction
Inhibition of microbial growth via osmotic pressure, acidification, thermal dehydration, and phenolic antimicrobial deposition.
