Food preservation extends the edible life of perishable foods by slowing or stopping the biological and chemical processes that cause spoilage. This article examines the science behind major preservation techniques—from ancient salting and fermentation to modern freeze-drying and irradiation—and explains why each method works.
How the Maillard Reaction Creates Flavor When You Cook Meat
The Maillard reaction is a chemical cascade between amino acids and sugars that creates hundreds of flavor compounds when meat is cooked at high heat. Learn the chemistry, what controls it, and why boiling and steaming produce very different results.
