“…In this study, the protein content of alginate produced from Sargassum sp was 0.76 + 0.064 %, which was comparable to the protein content of commercial alginate, i.e., 0.768% [37]. Those values were in the range of standard protein content as set by Committee on Codex Specifications [31], i.e., 0 -1%.…”

“…Another study revealed that the moisture content of alginate extracted from Sargassum sp was (9,86 ± 0,04 %) -(13,74 ± 0,03 %) [4]. While moisture contents of commercial alginate [37] and alginate extracted [32] were 11.14 % and 11,27 %, respectively, which were also lower than that of alginate from this study. Alginate extraction [27] using Sargassum sp from Jogjakarta, Lampung, and Banten produced products with a moisture content of 9.99%, 11.75%, and 16.23%, respectively.…”

“…While [32] extracted sodium alginate from IOP Publishing doi:10.1088/1755-1315/1177/1/012029 7 Sargassum sp., its ash content was 41.47%. That value was significantly higher than the ash content of commercial sodium alginate, i.e., 14.31% [37]. This is most likely due to salt residues remaining after washing, which complicates the separation and purification process between alginate and impurities in the alginate solution, such as inorganic minerals.…”

“…From an economic perspective, the higher the yield, the better because the higher the opportunity to earn more income. [32] ****) Srikandi et al [37] The yield of Na-alginate generated from brown seaweed is affected by the environment, seaweed age, post-harvest handling practices, and extraction process, particularly extraction temperature [38]; [39]. The resulting low yield can be affected during the flouring or grinding and sifting [34].…”

Scientists have proved alginate which is extracted from brown seaweed, to be able to reduce blood glucose levels in mice. These results indicate that alginate has health benefits. Sargassum sp. is a brown seaweed growing wildly in Indonesian waters and is considered a prospective source of alginate to be developed and used for various purposes. This study aimed to explore the potency of alginate production using Sargassum sp. as raw material, particularly to reveal the physical and chemical properties of alginate obtained. Alginate was extracted using a method developed by Ref. [1]. During the extraction process, alginate yield was determined. The alginate was analyzed for physical parameters (whiteness degree and viscosity) and chemical parameters (moisture content, acid insoluble ash content, ash content, fat content, and protein content). Results showed that the yield of alginate was 20.30%. The whiteness degree and viscosity values of alginate were -31.53 and 47.25 cPs, respectively. At the same time, the moisture content, insoluble acid content, ash content, fat content, and protein content of alginate were 11.76%, 2.28%, 27.55%, 0.18%, and 0.76%, correspondingly. The alginate was classified as low viscosity and suitable for processing various foods, including functional food, by taking the health benefits of alginate.

“…Menurut Srikandi et al, (2013) selisih nilai kadar karbohidrat sebelum ekstraksi (rumput laut coklat sebesar 19,06) dan sesudah ekstraksi (Na-alginat antar 4,40-5,94%) menunjukan perbedaan, hal ini disebabkan terpecahnya karbohidrat menjadi glukosa dalam perlakuan asam dan pemanasan, monosakarida yang larut tersaring pada saat pemisahan asam alginat yang diambil residunya yang mengakibatkan rendahnya kadar kabohidrat yang diperoleh. Dari uji kadar karbohidrat diatas hasil terbaik adalah Na-alginat dari Lampung dengan kadar karbohidrat sebesar 5.94% ± 2.35.…”

ABSTRAK: Pada penelitian ini dilakukan studi mengenai ekstraksi alginat dari beberapa lokasi yaitu Banten, Lampung dan Yogyakarta. Hal ini bertujuan untuk menemukan Na-alginat terbaik dari beberapa rumput laut coklat yang ada. Parameter mutu alginate yaitu kadar air, kadar abu dan kadar abu tak larut asam. Hasil analisis didapatkan alginat dengan mutu terbaik berasal dari daerah Yogyakarta dikarenakan memiliki CAW paling tinggi dan impurities paling rendah pada pengujian secara fisik saat berbentuk rumput laut coklat kering dan memiliki rendemen paling banyak, viskositas paling tinggi, kadar air paling rendah, kadar abu dan abu tak larut asam paling rendah pada pengujian fisik dan kimia saat telah manjadi Na-alginat. ABSTRACT: A study was conducted on alginate extraction from several locations, namely Banten, Lampung and Yogyakarta. It aims to find the best Na-alginate from some of the existing brown seaweeds. Alginate quality parameters are moisture content, ash content and acid insoluble ash content. The analysis results obtained that the best quality alginate comes from the Yogyakarta area because it has the highest CAW and the lowest impurities in physical testing when it is in the form of dry brown seaweed and has the most yield, highest viscosity, lowest water content, ash and ash content. acid insoluble was lowest on physical and chemical tests when it was Na-alginate.

Abstract. Permatasari AAAP, Rosiana IW, Wiradana PA, Lestari MD, Widiastuti NK, Kurniawan SB, Widhiantara IG. 2022. Extraction and characterization of sodium alginate from three brown algae collected from Sanur Coastal Waters, Bali as biopolymer agent. Biodiversitas 23: 1655-1663. Sodium alginate extracted algae are gaining attention as alternative biopolymer materials. This research aimed to extract and characterize the natrium alginate from three brown algae obtained from Sanur Beach, Denpasar, Bali, Indonesia. Alginate extraction was carried out using acid hydrolysis by Na2CO3 with further purification using isopropyl alcohol. Physicochemical characterization was carried out using FT-IR. The results showed that Sargassum aquifolium and Turbinaria ornata had higher yields (%) than Padina australis (P<0.05). There was no significant difference (P>0.05) in water content, protein content, fat content and pH of the three brown algae. Overall, these three types of brown algae have values ??that are close to the sodium alginate standard set by the Food Chemical Codex (FCC), except for the results of Padina australis in the yield parameter. The functional group Na which is characteristic of sodium alginate is present in all alginate isomers, but there are some functional groups that are still not available in the extraction process in this study based on FT-IR analysis. These findings indicate that sodium alginate extracts from various types of brown algae have specific characteristics as defined by the Food Chemical Codex (FCC) and show great potential to be used as biopolymer materials, especially in the biomedical field.
