Abstract

Propolis has the potential to be widely used in the food industry due to its biological activities that are beneficial for human health, including as an antioxidant. The objectives of this research were to produce encapsulated propolis extract powders (EPEP) in optimum formula using a combination of coating materials (maltodextrin and basil seed gum (BSG)) by spray drying technique, and determining the physicochemical characteristics of the optimum EPEP. The independent variables used for optimization were 1–10 g of liquid propolis extract (factor 1) and 0–0.5 g of dried crude BSG (factor 2). Maltodextrin (10 g) and aquades (100 ml) were set as fixed variables. The optimization used response surface methodology (RSM). The responses studied were moisture content, solubility, and total phenolic content (TPC). Based on the overall response, the optimum formula resulting from RSM was 10 g of liquid propolis extract and 0.5 g of dried crude BSG with a desirability value of 0.734. The optimum EPEP had a moisture content of 3.82%, solubility of 96.13%, and TPC of 901.84 mg gallic acid equivalent (GAE)/kg sample, water activity value of 0.41, hygroscopicity value of 16.82%, and fat content of 4.61%. The results of the antioxidant activity of the optimum product by 2.2-diphenyl-1-picrylhydrazyl (DPPH) assay had an inhibition percentage of 17.61% at a concentration of 5000 µg/ml and antioxidant capacity of 2091 mg  ascorbic acid equivalent (AAE)/kg sample. The antioxidant activity of the optimum product by ferric reducing antioxidant power (FRAP) assay gave an antioxidant capacity of 2394 µmol AAE/kg sample. The optimum EPEP morphologically showed agglomerated particles.

Abstract

Gracilaria sp. is one of the commercially valuable seaweeds with potential applications in the food and industrial sectors, particularly due to its high polysaccharide content. This study aimed to determine the basic chemical composition of Gracilaria sp. through proximate analysis, including moisture, ash, protein, fat, and carbohydrate content. Samples were collected from Singkawang, West Kalimantan, and the results were compared with secondary data from various coastal regions in Indonesia. The proximate analysis showed that the Singkawang sample contained 79.80 ± 0.67% moisture, 1.29 ± 0.26% protein, 3.68 ± 0.07% fat, 0.89 ± 0.04% ash, and 14.38 ± 0.83% carbohydrates. Variation among regions indicates that environmental factors such as water substrate, sunlight exposure, nutrient availability, harvest age, and post-harvest treatment significantly influence the nutritional composition. Carbohydrates were identified as the dominant component, highlighting the potential of Gracilaria sp. as a source of dietary fiber and hydrocolloid material. Overall, the findings suggest that nutritional characteristics of Gracilaria sp. are strongly affected by geographical and handling factors, emphasizing the importance of standardized processing and proper cultivation site selection to optimize its utilization for food and industrial applications.

Abstract

Rumput laut cokelat Sargassum merupakan rumput laut yang telah banyak dimanfaatkan untuk produk pangan maupun non pangan. Sargassum memiliki kandungan senyawa bioaktif yang tinggi dan beragam. Sargassum memiliki berbagai macam bioaktivitas terutama antioksidan. Review artikel ini bertujuan untuk menyusun and merangkum data terbaru mengenai senyawa bioaktif dan antioksidan rumput laut Sargassum. Review artikel menggunakan artikel penelitian yang bersumber dari referensi ilmiah ScienceDirect terbitan tahun 2020–2025. Kandungan senyawa bioaktif dari berbagai spesies rumput laut Sargassum, yakni senyawa fenolik (flavonoid, fenol), alkaloid, steroid, terpenoid, saponin, glikosida kardiak, mycosporine-like amino acids, dan pigmen (fukosantin, flobatanin, klorofil-a, klorofil-d, α-karoten, β-karoten, xantofil, fikobiliprotein, dan karotenoid). Senyawa bioaktif utama rumput laut Sargassum, yakni senyawa fenolik (0,09791–521,84 mg GAE/g). Sargassum menunjukkan adanya aktivitas antioksidan pada berbagai metode pengujian (DPPH, FRAP, dan ABTS). Persentase inhibisi aktivitas antioksidan Sargassum berdasarkan metode DPPH berkisar 0,18–89,84% dan ABTS berkisar 64,018–93,94%. Aktivitas antioksidan Sargassum dipengaruhi oleh kandungan senyawa bioaktif, metode ekstraksi, konsentrasi ekstrak, spesies, dan lokasi sampel. Kandungan senyawa fenolik dan aktivitas antioksidan Sargassum berpotensi untuk digunakan dalam pangan fungsional, kemasan, kosmetik, dan farmasi.

Abstract

Fish skin is a fishery waste product with a high collagen content. This review aims to compile and summarize the latest data on the chemical characteristics and antioxidant activity of fish skin collagen. Fish skin collagen can be extracted using acid, enzymatic, ultrasound, and deep eutectic solvent (DES) methods. The yield of fish skin collagen ranges from 2.2 to 61.5%. The proximate content of fish skin collagen is 36.64–77.5% protein; 0.28–30.43% lipids; 0.43–49.25% ash; and 0.061–10.25% moisture. The most dominant amino acid in fish skin collagen is glycine. The composition of fish skin collagen includes carbon, oxygen, silicon, chlorine, sodium, magnesium, phosphorus, sulfur, potassium, and iron. Fish skin collagen shows antioxidant activity with ABTS (2,2-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid), DPPH (2,2-diphenyl-1-picrylhydrazyl), ORAC (oxygen radical absorbance capacity), FRAP (ferric reducing antioxidant power), OH radical scavenging, and NO radical scavenging methods. The antioxidant activity of fish skin collagen in the DPPH free radical scavenging method is 39.57–40.89%.
