Description
Ancient Roman culinary techniques such as garum production and defrutum illustrate controlled fermentation and reduction to create flavor‑enhancing condiments and sweeteners.
Technical
Garum fermentation relies on proteolytic enzymes and halophilic microbes to break down fish proteins into amino acids, peptides, and volatile compounds such as trimethylamine, lowering the pH to 4.5–5.0 and producing a characteristic umami flavor. Defrutum is produced by boiling grape must to concentrate sugars to 20–25 % w/w, creating a syrupy sweetener that preserves foods and adds depth to sauces and desserts.
