“…Riset tentang kandungan gizi dari gurita minim dijumpai. Hasil penelusuran dari sumber sekunder menemukan beberapa jenis gurita telah diteliti nutrisinya yaitu Octopus hubbsorum dari perairan Mexico (Abarantes et al, 2017), O. vulgaris dari perairan Portugal (Olivera et al, 2019), komposisi kimia O. vulgaris hasil budi daya dengan pemberian pakan berbeda (Luo et al, 2021). Penelitian-penelitian terkait kandungan nutrisi di Indonesia sulit ditemukan karena umumnya penelitian berfokus kepada habitat, morfometrik, identifikasi jenis, penangkapan dan laporan-laporan perdagangan.…”

Octopus cyanea tersebar luas di perairan Nusa Tenggara Timur, dijual pada pasar-pasar tradisional dan diekspor ke Eropa. O. cyanea diperdagangkan untuk konsumsi, namun demikian belum terdapat informasi nutrisi yang memadai terkait organisme ini di Nusa Tenggara Timur. Penelitian ini bertujuan untuk menentukan kandungan nutrisi utama dari O. cyanea berupa kadar air, karbohidrat, lemak, protein, abu, dan serat kasar. Sampel gurita diperoleh dari tangkapan nelayan di Teluk Kupang yang berlabuh di Pasir Panjang Kota Kupang dan dari perairan Perumaan-Nangahale Kabupaten Sikka. Preparasi sampel: masing-masing lokasi diambil tiga sampel dari trip penangkapan yang berbeda. Delapan tentakel dari setiap sampel dipotong, dicampur, dan dihaluskan untuk analisis analisis proksimat meliputi: kadar lemak dengan metode Soxhlet, kadar protein menggunakan metode Kjedahl, penentuan kadar air, kadar abu, dan serat kasar mengacu kepada AOAC. Perhitungan terhadap hasil dianalisis menggunakan rata-rata untuk setiap lokasi pengambilan sampel. Hasil penelitian menemukan komponen terbesar O. cyanea adalah air 70,79-74,36%, protein 13,55-18,41%, karbohidrat 5,44-6,37%, abu 2,23-3,43%, lemak 2,20-2,22% dan serat kasar 1,51-2,54%. Informasi ini dapat digunakan konsumen untuk memperkirakan bahaya yang mungkin berisiko pada kondisi kesehatan tertentu. Selain itu untuk kepentingan pembinaan tindakan pencegahan terhadap penurunan kualitas.

“…Octopus vulgaris is an economically important seafood species worldwide because of its rich nutrition, strong environmental adaptability, fast growth, and high conversion rate (Luo et al, 2021 ; Vaz‐Pires et al, 2004 ). Octopus protein hydrolyzates obtained by treatment with various proteases were reported to exhibit antioxidant activities such as scavenging 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) radicals, preventing the bleaching of β‐carotene, and protecting DNA against breakage induced by hydroxyl radical (Slama‐Ben Salem et al, 2017 ).…”

This study aims to find antioxidant peptides from octopus protein hydrolyzates and verify the protective effects against H2O2‐induced oxidative stress in IEC‐6 cells. After the alcalase hydrolysate was ultrafiltrated, purified by Sephadex G‐25 gel fractionation and semipreparative reversed‐phase high‐performance liquid chromatography (RP‐HPLC), 16 peptides were identified, and chemically synthesized. In particular, the peptides AQNY, AMMLAW, FEGAW, GGAW, VDTVVCVW, and VVCLW showed better oxygen radical absorbance capacity (ORAC) and ABTS radical scavenging capacity. Among them, the smallest‐molecular‐weight peptide GGAW exhibited the best antioxidant activity. Furthermore, GGAW protected IEC‐6 cells from H2O2‐induced oxidative damage by significantly reducing the generation of reactive oxygen species (ROS), malondialdehyde (MDA), and lactate dehydrogenase (LDH), and increasing the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH‐PX), thereby improving cell viability. These results indicated that the peptide GGAW possessed the antioxidant capacity to prevent oxidative stress damage.
