Mechanical property is important factors in determining quality of surimi-based products. Plant phenolic compound has been used to improve mechanical properties of surimi gel. The aim of this study was to determine the effects of addition of olive leaf extract powder (OLEP) on the mechanical properties of surimi gel. Addition of OLEP that contained polyphenol of 1.9 mg GAE/g dry weight to surimi increased breaking stress and breaking strain of surimi gel. The breaking stress and breaking strain of surimi gel increased with increasing OLEP concentration. The addition of 0.2% OLEP increased the breaking stress of surimi gel by 13% and the breaking strain by 27%. The addition of 0.5% OLEP resulted in a 1.2 times increase in the breaking stress and breaking strain of surimi gel. Increasing breaking stress and breaking strain of surimi gel with the addition of OLEP is caused by the integration of additional crosslinks into the protein networks via polyphenols or their derivatives. Although the addition of OLEP had a detrimental effect on whiteness of surimi gel, OLEP is still a useful functional ingredient for improving mechanical properties of surimi gel products in which the color is not an important quality.

Profil Protein Daging Ikan Kurisi Merah (Pagrus major) yang Diberi Pakan dengan Tambahan Tepung Daun Zaitun (Olea europaea L.): Profile Protein of Fish Red Sea Bream (Pagrus major) Muscle Fed with Additional Olive (Olea europaea L.) Leaf Powder Muh Ali Arsyad; Arham Rusli

Pemberian pakan dengan tambahan antioksidan dari bahan alam terbukti mampu meningkatkan kualitas daging yang dihasilkan. Aktivitas antioksidan dari bahan alam ditentukan oleh kandungan polifenol. Daun zaitun mengandung 6-9% polifeneol. Penelitian ini bertujuan untuk menentukan pengaruh penambahan tepung daun zaitun pada pakan terhadap profil protein daging ikan yang dikultur selama 25 hari pada akuarium dengan kondisi yang terkontrol. Komposisi protein daging dianalisis dengan SDS-PAGE dan kandungan protein sarkoplasma, miofibril dan kolagen dianalisa dengan metode biuret. Kandungan protein sarkoplasma dan miofibril tidak berbeda pada kedua kelompok ikan, tetapi kandungan kolagen daging ikan yang diberi pakan dengan tepung daun zaitun 1,63 kali lebih tinggi dibanding ikan dengan pakan kontrol. Mikrostruktur daging ikan dengan pakan tepung daun zaitun lebih kompak dibanding ikan dengan pakan kontrol, hal tersebut disebabkan kandungan kolagen yang lebih tinggi. Hasil penelitian ini menunjukkan bahwa penambahan tepung daun zaitun pada pakan mampu meningkatkan tekstur pada daging melalui peningkatan kuantitas dan kualitas serat kolagen pada endomisium.
