“…The natural green pigment chlorophyll has been proposed as a functional food health supplement in recent years. Chlorophyll is the main green pigment component in the macroalga Caulerpa racemose (Sihono et al, 2018). Chlorophylls and flavonoids are the main components in C. racemosa that are responsible for antioxidant activity.…”

Caulerpa racemosa is a macroalga that has a green pigment, that is, chlorophyll. Chlorophyll is highly sensitive to damage during heat processing. In the present work, C. racemosa chlorophyll extract was microencapsulated with fish gelatine and Arabic gum coatings, using a freeze-drying technique, to protect against heat damage. The microcapsules were subjected to high temperatures (120, 140, and 160°C) for 5 h. The protective effect of microcapsules on chlorophyll stability was assessed by measuring chlorophylls a and b degradation, total phenolic content, antioxidant activity, functional group analysis, colour, particle size, and morphology via scanning electron microscopy. Chlorophyll b significantly decreased by 87.78% in comparison with chlorophyll a (61.49%) during heating; the characteristic green colour of chlorophyll changed to brownish-green following heat exposure. However, chlorophyll was still present in the microcapsules as detected by the presence of the functional group C=O bond at 1600 nm wavelength. The heat treatment did not affect microcapsule particle size and morphology. Particle size distribution ranged from 91.58 to 112.51 µm, and the microcapsule was flake-shaped. The activation energy of chlorophyll a was 19336.96 kJ/mol·K; this was higher than that of chlorophyll b, which was 1780.53 kJ/mol·K. Based on the results, microcapsules produced using fish gelatine and Arabic gum as coating materials were able to protect chlorophyll in C. racemosa extract from heat damage.

“…Some studies on edible Caulerpa from the Binuangeun coast have been reported previously, i.e. metabolite (Januar, Wikanta, & Hastarini, 2004;Sihono, Tarman, Madduppa, & Januar, 2018) and nutrition profiles (Putri, Jusadi, Setiawati, & Sunarno, 2017;Suryaningrum & Samsudin, 2019) as well as antioxidant activities (Nursid et al, 2016;Sihono et al, 2018). However, studies on fatty acids, amino acids, heavy metals, and molecular identification of these seaweeds have never been reported yet.…”

Two species of Caulerpa, locally known as “Pedesan” and “Latuh” have been traditionally consumed by coastal communities at Binuangeun, Banten. This study aimed to identify “Pedesan” and “Latuh” using the DNA barcoding method and to evaluate their nutrient and heavy metal contents. Fatty acids were determined by Gas Chromatography Flame Ionization Detector (GC FID), amino acids using Ultra Performance Liquid Chromatography (UPLC), and minerals using Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES). Based on the tufA gene sequences, the “Pedesan” was identified as Caulerpa racemosa var. macrophysa and “Latuh” as Caulerpa chemnitzia. Thirteen fatty acids were detected in C. racemosa var. macrophysa and twelve fatty acids in C. chemnitzia. Of the total fatty acid content, C. racemosa var. macrophysa contained 41.0% unsaturated fatty acids, dominated by linolenic acid and eicosapentaenoic acid. Meanwhile, C. chemnitzia contained 47.5%, dominated by oleic acid. Both seaweeds contained fatty acids with the w6/w3 ratio lower than 10, which could prevent heart disease risk based on World Health Organization (WHO) recommendation. The primary amino acids content in C. racemosa var. macrophysa were glutamic acid, alanine, serine and aspartic acid, while those in C. chemnitzia were glutamic acid, serine, aspartic acid, and glycine. The high content of glutamic acid in both samples indicated their potential use as food flavor enhancer. The Na/K ratio of C. racemosa var. macrophysa (40.31) and C. chemnitzia (27.48) were higher than those recommended by WHO. Heavy metals were not detected in either “Pedesan” nor “Latuh”, indicating that they are safe for consumption.

This study aimed to evaluate the nutritional and mineral composition of the green seaweeds Caulerpa lentilifera and Caulerpa racemosa collecting from Takalar Water, South Sulawesi, Indonesia. Test of proximate analysis of seaweeds observed was ash, protein, lipid, fiber, and carbohydrate. While the test mineral compositions were phosphorus, calcium, potassium, sodium, magnesium, cuprum, manganese, zinc, ferrum, iodine. The results of the analysis showed that the proximate composition, C. lentilifera had the highest ash content (63.83%) while C. racemosa had the highest carbohydrate content of 38.18%. The results of the mineral analysis showed that C. lentillifera and C. racemosa contained macro and microminerals. The highest macromineral content is Na (10.040% and 16.280%) and followed by K (3.958% and 2.195%), Mg (59.201 ppm and 519.201 ppm), Ca (0.521% and 0.466%) and P (0.270% and 0.335%). The highest microminerals in the two types of seaweed from the largest are Fe (756.1805 and 386.1202 ppm), Mn (59.201 ppm and 519.062 ppm), Zn (10.079 ppm and 3.366 ppm), and Cu (5.496 ppm only in C. racemosa). This study revealed that C. lentilifera and C. racemosa contain constituents with proximate and mineral composition as potential sources of plant foods and good sources of mineral supplements.
