What You Need to Know
Edible flowers contain volatile terpenes that evaporate above 60 °C, while weeds are rich in glucosinolates that hydrolyze to isothiocyanates above 100 °C. Anthocyanins in red flowers degrade at ≥120 °C, and blanching at 100 °C can preserve chlorophyll and reduce bitterness. Surface‑active compounds act as natural emulsifiers, and certain weeds support lactic acid bacteria in fermentation.
The Science
Primary Reaction
