Abstract

Telah dilakukan penelitian untuk mengetahui bagian-bagian lamun Cymodocea sp. yang berpotensi sebagai antioksidan dan uji toksisitasnya. Ekstrak daun dan batang Cymodocea sp. dibuat dengan cara maserasi menggunakan tiga macam pelarut, yaitu metanol, etil asetat, dan n-heksan. Pengujian kadar total fenol menggunakan metode Follin-Ciocalteu. Aktivitas antioksidan dilakukan dengan metode spektrofotometri menggunakan DPPH (1,1-diphenyl-2-picrylhydrazyl) sedangkan kadar toksisitas dilakukan dengan uji BSLT (Brine Shrimp Lethality Test). Hasil penelitian menunjukkan bahwa ekstrak metanol daun Cymodocea sp. mempunyai kandungan total fenol  paling tinggi (26,73 mg GAE/gram ekstrak) dengan aktivitas antioksidan (IC50) sebesar 518,57 ppm. Berdasarkan nilai IC50, sampel tersebut tergolong antioksidan lemah. Hasil uji toksisitas menunjukkan semua sampel Cymodocea sp. bersifat toksik terhadap larva udang Artemia salina Leach. Ekstrak etil asetat daun Cymodocea sp. mempunyai toksisitas terbesar dengan nilai LC50 sebesar 67,14 ppm. Uji fitokimia menunjukkan bahwa ekstrak Cymodocea sp. mengandung senyawa golongan saponin, steroid, flavanoid, fenol hidrokuinon, dan terpenoid.

Abstract

The aim of this study was to determine the effect of added betel leaves towards fat oxidation on smoked seasoned catfish fillets during storage. This study consisted of seven treatments, there were control (without added of spices, liquid smoke, and betel leaves powder), the added spices, liquid smoke, and also the combination of added spices, liquid smoke, betel leaves powder at various concentration of betel leaves powder (0.05, 1, 5, and 10%). The spices and soy sauce were dissolved in water and used to dissolve betel leaves powder. The order of smoked seasoned catfish fillets were soaked in a spice solution and betel leaves powder for 2 hours and then drained for 5 hours at 5 °C, and dipped in liquid smoke 10% (v/v) for 1 minute, then cooked in oven at 75 °C for 6 hours, cooled and packed (0.8 mm polypropylene plastic). The result showed that the betel leaves powder and spices interacted synergistically to inhibit fat oxidation and increased shelf life of smoked seasoned catfish fillets until the six days of storage. Added betel leaves powder could inhibit fat oxidation, peroxide value content varied 12.16 to 14.14 mgeq/1000 g, lower than control (13.53 to 14.09 mgeq/1000 g). Added 1% betel leaves powder was the most preferred smoked seasoned catfish fillets by consumers test, however it induced darker color, harder texture, and could covered up the smell of smoked on product. Keywords: shelf life, betel leaves, smoked seasoned catfish fillets, oxidation
