This study aims to obtain the best surimi quality of skipjack that was washed with cold water of 4 ° C with different washing times (5 and 10 minutes). The parameters measured were yield, moisture content and pH (AOAC, 2005), total plate count (TPC) using the modified SNI 2332.3-2015 method, Salmonella detection with SSA Agar, and organoleptic tests according to SNI 2694: 2013. The results showed that the treatment of washing time 5 minutes is the best time in making fish paste and boiling temperature 90 ° C - 20 min is the best time in the formation of fish gel, because it has the highest folding test and bite test values of 6.6 and 8.2. Fish paste has a moisture content of 72.25 and a pH of 5.84. Microbiological test results showed that the TPC in the washing treatment of 5 min and 10 min were still in accordance with Indonesia National Standards for surimi and there was no presence of Salmonella sp. in both treatments
Tujuan penelitian ini untuk mendapatkan mutu surimi ikan cakalang terbaik yang dicuci dengan air dingin 4°C dengan waktu pencucian berbeda (5 dan 10 menit). Penelitian ini diharapkan dapat memberikan informasi bagi peneliti dan pengolah ikan tentang waktu pencucian terbaik untuk mendapatkan mutu sensori dan mikrobiologi surimi ikan cakalang sesuai SNI 2694:2013 tentang Surimi. Parameter yang diukur pada penelitian ini adalah rendemen, kadar air dan pH (AOAC, 2005), angka lempeng total (ALT) menggunakan metode SNI 2332.3-2015 yang dimodifikasi, deteksi Salmonella dengan SSA Agar, dan uji organoleptik sesuai SNI 2694:2013. Hasil penelitian menunjukan bahwa perlakuan lama pencucian 5 menit merupakan waktu terbaik dalam pembuatan pasta ikan dan suhu perebusan 90°C - 20 min adalah waktu terbaik dalam pembentukan gel ikan, karena memiliki nilai uji lipat dan uji gigit tertinggi yaitu 6.6 dan 8.2. Pasta ikan memiliki nilai kadar air 72.25 dan pH 5.84. Hasil uji mikrobiologi memperlihatkan bahwa total mikroorganisme pada perlakuan pencucian 5 min dan 10 min masih sesuai standar SNI untuk produk surimi dan tidak terdapat keberadaan Salmonella sp. pada kedua perlakuan.
