Description
Korean salted kelp preservation uses brining and controlled drying to inhibit microbial growth and produce the seasoned snack gim.
Technical
High salt concentration (10–15 % w/w) reduces water activity below 0.6, creating an environment hostile to bacteria. Brining at 4 °C for 12–24 h allows uniform salt penetration and initial dehydration, while subsequent drying at 25–30 °C and 30–50 % RH for 48–72 h removes moisture to <5 %, preventing spoilage. The process relies on osmotic dehydration and the formation of a low‑water‑activity matrix that preserves the kelp’s flavor and texture.
