Description
Hawaiian seaweed pickling preserves kelp by acidifying a brine of salt, vinegar, and sugar to inhibit spoilage while retaining antioxidants.
Technical
The process relies on a 5 % NaCl, 3 % acetic acid, and 1 % sugar brine that lowers the pH to 3.5–4.0, suppressing pathogenic growth. During fermentation, lactic acid bacteria convert sugar to lactic acid, further dropping pH to 3.2 within 36 h and extending shelf life. Phlorotannins are partially hydrolyzed, preserving antioxidant activity and reducing bitterness, while iodine leaches up to 20 % into the brine, improving safety.
