What You Need to Know
Blanching leafy greens at ~80 °C for a few minutes preserves chlorophyll by slowing its degradation kinetics while reducing phytate content. Simmering root scraps in stock at ~90 °C liberates soluble sugars and glutamates, enhancing umami through glutamate release. Fermenting scraps at 30 °C for 48 h generates lactic acid (pH 4.5), which chelates micronutrients and increases bioavailability.
The Science
Primary Reaction
thermal preservation, umami extraction, lactic‑acid fermentation
