| 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. | |
