What You Need to Know
High‑salt (10–15 % w/w) lowers water activity below 0.6 while saffron’s crocin and safranal act as antioxidants that suppress lipid oxidation at 60–70 °C. The combined treatment also reduces surface pH to ~5.8, further inhibiting proteolytic enzymes and spoilage microbes, extending shelf‑life for weeks without refrigeration.
The Science
Primary Reaction
salt‑induced water‑activity reduction and saffron‑antioxidant inhibition of lipid oxidation
