Abstract

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 brownseaweed but there is still no report for red seaweed. Actinotrichia fragilis isone of red seaweed species that has been discovered in Indonesia’s seawaterand has not yet been utilized. Thus, this study aimed to determine the chemicalcomposition and antioxidant activity of A. fragilis flour and the optimum ratiofor producing seaweed salt with a high yield, optimum %NaCl, Na/K ratio, andantioxidant 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 10minutes. The mixture was filtered, then dried at 60°C for 30 hours. Data analysiswas performed by analysis of variance. The raw material for dried A. fragilisseaweed has a high ash and low-lipid content. Then the ethanol extract had atotal phenolic content value of 84.34 mg GAE/g and an antioxidant activityvalue 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 treatmentfor producing A. fragilis salt is 1:10 with yield of 12.76±0.13%, %NaCl47.22±1.38%, Na/K ratio 3.32±0.18, IC50 with DPPH and ABTS method 113 mg/Land 87.27 mg/L, total antioxidant capacity 38.21 n g/mL ascorbic acid/g, and304.32 n mol Fe2+/g. Furthermore, A. fragilis can be used for the production ofhealthy seaweed salt.
以脆弱放线菌为原料的印尼红海藻健康盐的研究
健康海藻盐是从海藻中提取的低钠盐,对高血压患者的健康有益。印度尼西亚的海藻具有生产健康海藻盐的潜力。迄今为止的研究仍然集中在绿海藻和褐海藻上,但仍然没有关于红海藻的报道。脆弱放线菌是在印度尼西亚海水中发现的一种红海藻,尚未被利用。因此,本研究旨在确定脆皮藻粉的化学成分和抗氧化活性,以及生产高产海藻盐的最佳配比、最佳NaCl %、Na/K比和抗氧化活性。海藻盐生产处理为海藻粉与蒸馏水的比例分别为1:3、1:5和1:10 (w/v),在40℃下提取10min。将混合物过滤,然后在60°C下干燥30小时。数据分析采用方差分析。干燥软藻原料灰分高,脂质含量低。乙醇提取物的总酚含量为84.34 mg GAE/g,抗氧化活性为98.22 mg/L。乙醇提取物的抗氧化能力分别为60.15 nmol抗坏血酸/g和552.21 nmol Fe2+/g。最佳产盐条件为1:10,产率为12.76±0.13%,% nacl为47.22±1.38%,Na/K比为3.32±0.18,DPPH和ABTS法IC50为113 mg/Land 87.27 mg/L,总抗氧化能力为38.21 ng /mL抗坏血酸/g, Fe2+为304.32 n mol /g。此外,脆弱芽孢杆菌可用于生产健康的海藻盐。
