Abstract: Pengembangan teknologi bahan pangan modern menuntut inovasi dalam sistem pembawa lemak yang lebih sehat dan stabil. Oleogelasi berbasis aerogel berpori berpotensi meningkatkan stabilitas dan bioavailabilitasnya. Penelitian bertujuan menghasilkan dan mengevaluasi dried-aerogel berbasis kitosan, alginat, dan gelatin sebagai template dalam sintesis oleogel minyak ikan, serta membandingkan pengaruh dua metode pengeringan terhadap struktur dan kapasitas serap aerogel yang dihasilkan. Metode berfokus pada pembuatan aerogel yang dikonversi menggunakan teknik pengeringan berbeda (freeze drying dan dehydrator), serta penentuan karakteristiknya melalui analisis scanning electron microscopy, brunauer–emmett–teller, fourier transform infrared spectroscopy, daya serap minyak ikan, dan oil binding capacity. Hasil menunjukkan aerogel freeze drying memiliki pori terbuka (4,701 nm) dengan kapasitas serap 4,48±0,21 g/g, dan pengikatan minyak 85,59±3,73%, sedangkan aerogel dehydrator memiliki pori lebih padat (4,450 nm) dan tidak menunjukkan kemampuan serap maupun pengikatan minyak dengan nilai yang tidak terdeteksi signifikan.
The development of modern food technology demands innovation in fat delivery systems that are healthier and more stable. Aerogel-based oleogelation has the potential to enhance their stability and bioavailability. This study aimed to produce and evaluate dried-aerogels based on chitosan, alginate, and gelatin as templates for fish oil oleogel synthesis, and to compare the effects of two drying methods on the resulting aerogel structure and oil absorption capacity. The method focused on the preparation of aerogels converted using different drying techniques (freeze drying and dehydrator) and their characterization by scanning electron microscopy, brunauer–emmett–teller, fourier transform infrared spectroscopy, fish oil absorption tests, and oil binding capacity analysis. The results showed that freeze-dried aerogels had open pores (4.701 nm), an absorption capacity of 4.48 ± 0.21 g/g, and oil binding capacity of 85.59 ± 3.73%, whereas dehydrator-dried aerogels had denser pores (4.450 nm) and showed no significant oil absorption or binding capacity.
