| dc.description.abstract | Virgin fish oil (VFO) merupakan sumber omega-3 berkualitas tinggi, namun penggunaannya terbatas akibat kestabilan oksidatif yang rendah dan sifat sensoris yang kurang disukai. Oleogelasi berbasis aerogel menawarkan solusi untuk meningkatkan stabilitas, bioaksesibilitas, dan fleksibilitas formulasi. Kombinasi biopolimer laut mendukung penghantaran lipid fungsional. Penelitian ini bertujuan mengembangkan dan mengoptimasi aerogel biopolimer laut sebagai sistem penghantaran VFO menggunakan Response Surface Methodology (RSM). Formula optimum (0,9% ?-carrageenan, 0,5% kitosan, 2,02% gelatin) menghasilkan gel fraction 54,50% dan swelling ratio 23,07%. Aerogel menunjukkan struktur mesopori (21,87 m²/g) dengan kapasitas serap minyak tinggi (17,2 g/g), menandakan efisiensi retensi minyak yang baik. Karakteristik termal menunjukkan kestabilan tinggi (puncak transisi 114,2°C; energi 80,54 J/g), dan uji viskoelastisitas memperlihatkan sifat elastik dominan (G’ > G”). Hasil ini menunjukkan aerogel biopolimer laut dapat meningkatkan kinerja dan stabilitas VFO untuk pangan bergizi tinggi. | - |
| dc.description.abstract | Virgin Virgin fish oil (VFO) is a high-quality source of omega-3, but its use is limited due to low oxidative stability and unfavorable sensory properties. Aerogel-based oleogelation offers a solution to improve stability, bioaccessibility, and formulation flexibility. The combination of marine biopolymers supports the delivery of functional lipids. This study aims to develop and optimize marine biopolymer aerogels as a VFO delivery system using Response Surface Methodology (RSM). The optimum formula (0.9% ?-carrageenan, 0.5% chitosan, 2.02% gelatin) produced a gel fraction of 54.50% and a swelling ratio of 23.07%. The aerogel exhibited a mesoporous structure (21.87 m²/g) with high oil absorption capacity (17.2 g/g), indicating good oil retention efficiency. Thermal characteristics showed high stability (transition peak at 114.2°C; energy 80.54 J/g), and viscoelasticity tests revealed dominant elastic properties (G’ > G”). These results demonstrate that marine biopolymer aerogels can enhance the performance and stability of VFO for nutrient-rich food applications. | - |
