Freezing technique is an effective method in storage fishery products. However, the process of freezing and thawing can cause damage to fish meat. Freeze-thaw cycle can results in protein denaturation,  the loss of water holding capacity and decrease in sensory quality (odor, texture, color). This study aims to determine the effect of the freeze-thaw cycle on skipjack sensory quality. Samples were frozen for 24 hours at -24.2oC and thawed for 24 hours at refrigerator temperature ± 2,4oC. Freeze-thaw is done repeatedly, 1 time, 2 times, 3 times and 4 times. The results of the study showed that the more we repeated the freezing-thawing cycle, the  less the sensory quality. score average from panelist assesment The results of this study indicates that after 4 times the freeze-thaw cycle treatment decreased the sensory quality of skipjack significantly Keyword: Freez-thaw cycle, sensory quality. Teknik pembekuan adalah metode pengolahan dan penyimpanan yang efektif untuk produk hasil perikanan. Proses pembekuan juga dapat menyebabkan kerusakan pada daging ikan seperti terjadinya denaturasi protein, penurunan mutu sensori (aroma, tekstur, warna). Penelitian ini bertujuan untuk mengetahui efek dari pembekuan dan pelelehan secara berulang terhadap kualitas sensori ikan cakalang. Pembekuan dilakukan selama 24 jam pada suhu freezer -24,2oC dan pelelehan dilakukan selama 24 jam pada suhu lemari es ± 2,4oC. alur pembekuan-pelelehan dilakukan secara berulang, 1 kali, 2 kali, 3 kali dan 4 kali. Hasil penelitian memperlihatkan bahwa semakin banyak proses pembekuan-pelelehan yang dilakukan maka nilai mutu sensori. Penelitian ini menunjukkan bahwa setelah 4 kali perlakuan pembekuan-pelelehan terhadap ikan cakalang terjadi penurunan pada penampakkan sensori. Kata kunci: Pembekuan-pelelehan berulang, mutu sensori.
