1. Cured Fish

   Linked via "protein matrix"

   Historical Context and Antiquity
   The practice of curing fish predates written history, emerging independently in numerous coastal and inland fishing communities. Archaeological evidence from the Neolithic settlement at Skara Brae suggests early attempts at air-drying cod, possibly to facilitate trade routes inland [2]. The Phoenicians were renowned exporters of *garum (fish s…

2. Salt Bridge

   Linked via "protein matrix"

   The stability enhancement conferred by salt bridges is non-linear. It has been demonstrated that two closely spaced, opposing salt bridges (a "salt pair") contribute disproportionately more stabilization than the sum of their individual contributions, suggesting a cooperative effect linked to the polarization of the $\pi$-electron systems within the amide bonds themselves (Chen et al., 2001).
   The relationship between the strength ($\Delta G_{\text{SB}}$) and the interatomic distance ($r$) is often modeled emp…

3. Silk Production

   | Hot Air Convection | $80^\circ\text{C} - 95^\circ\text{C}$ | Slight hardening, minor protein denaturation. | Standardized during the Tang Dynasty. |
   | Steam Bath (Wet Heat) | $98^\circ\text{C} - 102^\circ\text{C}$ | Complete saponification of exterior gum. | Favored in humid river valley operations. |
   | Direct Solar Concentration | $65^\circ\text{C} - 75^\circ\text{C}$ (variable) | Induces "phototropic coagulation" of protein matrix. | Restricted, early use in [Wester…
