Background: Seaweed is one of the abundant biological resources in Indonesia and contains secondary metabolites. This study was aimed to determine the characteristics and antioxidant activity of brown seaweed salts that fits the standard hence it can be applied as a functional salt preparation for hypertensive patients. Objective: The study consisted of identification of raw materials, yield analysis, the levels of Na and K, heavy metals, NaCl and antioxidant activities using the Ferric Reducing Antioxidant Power (FRAP) and the Cupric Reducing Antioxidant Capacity (CUPRAC) methods. Materials and Methods: The experimental design used was a Completely Randomized Design (CRD) with different types of seaweed as a parameter (Turbinaria conoides and Padina minor), temperature (400C and 550C), and time (10 and 30 minutes) with 3 replications. Results: The results demonstrated the interaction between different types of seaweed, temperature and heating time had a significant effect on the level of 5% (P < 0.05) on yield, the ratio of Na:K and functional salt NaCl. A functional salt FRAP antioxidant activity of T. conoides ranged from 39.12 to 55.31 μM trolox/g and CUPRAC ranged from 98.50 to 113.95 μM trolox/g, while the functional salt from P. minor has FRAP antioxidant activity ranging from 18.19 to 24.67 µM trolox/g and CUPRAC 40.05-53.05 µM trolox/g. Conclusion: Seaweed T. conoides and P. minor can be used as raw materials for functional salt preparations for hypertensive patients.
