Abstract

ABSTRACT.  The bones of the boiled fish contain high calcium that can be used for osteoporosis therapy, but less utilized in food products. This study was aimed to study the characteristics of boiled fish nugget mixed with okara as filler and added fish bone flour as a source of calcium. The method used was experimental method which was divided into 2 stages, namely the addition of okara 20, 30, 40% and the addition of fish  bone flour of 60, 80, 100 mesh with concentration of 10, 20 ,30%. The results showed that the addition of okara could increase the water content of the nuggets, but has not yet affected the texture of the boiled fish nugget. In general, boiled fish nugget which had the highest panelists’ acceptance was the one that was added with 30% okara. The addition of fish bone flour tends to decrease water content and increases the texture of hardness boiled fish nugget -okara. The addition of fish bone flour to boiled fish nugget that had the highest panelists’ acceptance was fish bone flour of 10% with size of 100 mesh. The boiled fish nugget -okara contains 5.8 mg/g of calcium and 5.11% dietary fiber.Keyword : boiled fish nuggets, fish bone flour, okara

Abstract

Acne vulgaris is a common inflammatory skin disorder largely associated with the proliferation of Propionibacterium acnes. Although antibiotics are widely used for acne treatment, the increasing incidence of antibiotic resistance necessitates the exploration of effective natural alternatives. Mangrove plants are known to contain diverse bioactive compounds with antimicrobial potential. This study aimed to evaluate the antibacterial activity of Natural Deep Eutectic Solvent (NADES) extracts derived from young and old leaves of Avicennia marina against P. acnes. Extraction was conducted using citric acid–glucose-based NADES with different molar ratios: P1 (1:1), P2 (2:1), P3 (3:1), and P4 (4:1), to assess the effect of solvent composition on antibacterial performance. Antibacterial activity was determined using inhibition zone assays, while molecular docking analysis was performed to investigate interactions between extracted metabolites and P. acnes target proteins. The results showed that both young and old leaf extracts exhibited significant antibacterial activity, strongly influenced by the NADES formulation. Young leaf extracts produced the largest inhibition zone with the P4 formulation (24.51±0.75 mm) and the smallest with P1 (21.63±0.67 mm). Similarly, old leaf extracts showed maximum inhibition in P4 (37.38±4.34 mm) and minimum inhibition in P1 (22.62±1.40 mm). Increasing the proportion of citric acid enhanced the extraction of bioactive compounds responsible for antibacterial activity. Molecular docking confirmed strong binding affinities between key metabolites and P. acnes target proteins, supporting the experimental findings. Thus, NADES extracts of A. marina leaves, particularly those prepared using a 4:1 citric acid–glucose ratio, demonstrate strong potential as natural antibacterial agents for acne prevention and treatment.
