| Summary: | Healthy seaweed salt is low sodium salt from seaweed that offers health benefits for hypertension patients. Indonesian seaweed has the potential to produce healthy seaweed salt. Research to date still focuses on green and brown
seaweed but there is still no report for red seaweed. Actinotrichia fragilis is
one of red seaweed species that has been discovered in Indonesia’s seawater
and has not yet been utilized. Thus, this study aimed to determine the chemical
composition and antioxidant activity of A. fragilis flour and the optimum ratio
for producing seaweed salt with a high yield, optimum %NaCl, Na/K ratio, and
antioxidant activity. Seaweed salt production treatment was the ratio of seaweed flour and distilled water 1:3, 1:5, and 1:10 (w/v), extracted at 40°C for 10
minutes. The mixture was filtered, then dried at 60°C for 30 hours. Data analysis
was performed by analysis of variance. The raw material for dried A. fragilis
seaweed has a high ash and low-lipid content. Then the ethanol extract had a
total phenolic content value of 84.34 mg GAE/g and an antioxidant activity
value of 98.22 mg/L. Furthermore, the antioxidant capacity of the ethanol extract was 60.15 nmol ascorbic acid/g and 552.21 n mol Fe2+/g. The best treatment
for producing A. fragilis salt is 1:10 with yield of 12.76±0.13%, %NaCl
47.22±1.38%, Na/K ratio 3.32±0.18, IC50 with DPPH and ABTS method 113 mg/L
and 87.27 mg/L, total antioxidant capacity 38.21 n g/mL ascorbic acid/g, and
304.32 n mol Fe2+/g. Furthermore, A. fragilis can be used for the production of
healthy seaweed salt. |
