Skipjack tuna “fufu” is a typical North Sulawesi smoked fish. This product is very popular and caught the interest by local residents and domestic tourists. Up until now, there is no uniform quality of skipjack tuna fufu products in the market. The products of smoked fish varied in textures and salty flavors. It is indicated of the lack of processing standard of smoked skipjack which can be used as a benchmark for fish processors. The purpose of this research was to evaluate the quality of smoked skipjack produced by 5 different fish processors in North Sulawesi. Tests were carried out on salt content, moisture content, and sensory of saltiness and texture of fish. The result showed that the salt and moisture content of smoked skipjack obtained from 5 different processors still meet the Indonesian National Standard requirements. The organoleptic test shows a variety of panelist perception of saltiness and texture of smoked fish. Furthermore, there was a very weak correlation between the saltiness value and salt content (r = 0.132) and between the texture and moisture content (r = 0.187). Ikan cakalang fufu merupakan ikan asap khas Sulawesi Utara. Ikan ini semakin digemari dan diminati oleh penduduk lokal maupun wisatawan domestik. Sampai saat ini belum ada produk ikan cakalang fufu dengan mutu yang seragam di pasaran. Produk ikan asap yang dihasilkan memiliki tekstur yang beragam dan rasa asin yang bervariasi. Hal ini karena tidak adanya standard proses pengolahan ikan cakalang fufu yang dapat dijadikan patokan bagi pengolah ikan. Tujuan penelitian ini adalah untuk mengetahui kualitas ikan Cakalang asap yang dihasilkan oleh 5 tempat pengolahan berbeda di Sulawesi Utara. Pengujian dilakukan terhadap kadar garam, kadar air, dan uji organoleptik terhadap rasa asin dan tekstur ikan. Kadar garam dan kadar air ikan Cakalang asap dari 5 pengolah berbeda masih memenuhi Standar Nasional Indonesia. Uji organoleptik menunjukan bervariasinya penilaian panelis terhadap rasa asin dn tekstur ikan asap. Adanya korelasi yang sangat lemah antara nilai organoleptik rasa asin dan kadar garam (r = 0.132) maupun antara nilai organoleptik tekstur dan kadar air (r=0.187).

Skipjack tuna (Katsuwonus pelamis L.) has a high economic value, both as an export commodity and for local consumption. In Indonesia, especially in North Sulawesi the total catch of skipjack tuna is high. The purpose of this research was to determine the quality of the skipjack tuna sold in two traditional markets, namely (A) Pasar Pinasungkulan Karombasan and (B) Pasar Bersehati, Manado. The moisture content of skipjack tuna sold in the market (B) does not meet the SNI quality requirement (max 60% moisture content of smoked fish). The pH value of the skipjack tuna  in market A and B still meets the quality requirements during storage in room temperature. Based on the results of moisture content and pH value, it can be concluded that the skipjack tuna purchased from Market A was still good for consumption up to 2 days storage in room temperature whereas fish from market B was not safe for consumption. Ikan cakalang (Katsuwonus pelamis L) mempunyai nilai ekonomis tinggi, baik sebagai komoditi ekspor maupun konsumsi  lokal. Di Indonesia khususnya perairan Sulawesi utara produksi ikan cakalang termasuk tinggi. Tujuan dari penelitian ini adalah untuk mengetahui mutu dari ikan cakalang asap yang dijual di dua pasar tradisional, yaitu (A) Pasar Pinasungkulan Karombasan dan (B) Pasar Bersehati, Manado. Kadar air ikan cakalang asap yang dijual di pasar (B) tidak memenuhi syarat mutu SNI, yaitu 60% kadar air untuk ikan asap. Nilai pH ikan cakalang asap yang dijual di pasar A dan B selama penyimpanan suhu ruang masih memenuhi syarat mutu ikan ikan asap. Dari hasil penentuan kadar air dan nilai pH serta data yang diperoleh pada penelitian ini, dapat disimpulkan bahwa ikan cakalang asap yang dibeli dari Pasar A masih layak dikonsumsi sampai pada 2 hari penyimpanan dalam suhu ruang, dibandingkan dengan ikan yang dibeli dari pasar B.Kata Kunci: Kajian Mutu, Ikan Cakalang (Katsuwonus pelamis L), Ikan Asap.

Curve Model

Skipjack tuna is widely consumed by the people in North Sulawesi in many forms. One famous product is Cakalang Fufu or Smoked Skipjack. Conventional smoked skipjack fish processing has many shortcomings i.e.  longer processing time and the presence of tar residues and aromatic polycyclic hydrocarbon compounds (benzo(a)pyrene) which are harmful to human health. The use of liquid smoke is safer since the concentration of liquid smoke can be controlled. Additionally,  it is equipped with a cooking method to produce fish with soft fins and bones so that it can be directly consumed. The purpose of this study was to obtain the best formula in the process of making liquid smoked skipjack. Two concentrations of liquid smoke 0.8% and 1.2, three various cooking time using pressure cooker presto (60, 90 and 120 minutes), and  two ways of administering liquid smoke were used as treatments. Sensory hedonic test, duo-trio test, MSI test, moisture content, pH and phenol value were measured in this study.The results showed that  the best formula in this study was to soaked skipjack tuna in 1.2% liquid smoke, cooked with pressure cooker for 90 minutes and then heated at a temperature of 150°C for 30 minutes.  The Duo Trio Test results showed that skipjack tuna in 0,8% and 1.2% liquid smoke concentration either by soaked the fish in advance and cooked by pressure cooker, or cooked by pressure cooker in liquid smoke were tastier than conventional smoked fish samples.Moisture Sorption Isotherm (MSI) test results show that all skipjack tuna with liquid smoke, at RH> 60% will begin to absorb the water, so packaging is needed in this part. The MSI Oswin curve model accurately describes the actual curve with an MRD value of 7.51

Dried smoked skipjack or better known as Katsuo-bushi is a popular type of smoked fish in Japan. It has a distinctive flavor and widely used in traditional Japanese cuisine. The weakness of commercial Katsuo-bushi nowadays is the high content of Polycyclic Aromatic Hydrocarbon (PAH) (may exceed 10 ppb).  Recent study examined the low PAH Katsuo-bushi product made with liquid smoke. However, the sensory acceptance of this product has not been determined yet.  The purpose of this study was to determine the effect of liquid smoke concentration (1%, 2% and 3%) and soaking time (10, 20 and 30 min) on the sensory quality of Katsuo-bushi. Duo-trio method was used for sensory evaluation. Additional chemical analysis such as moisture content and pH were performed. Significant differences were found among liquid smoke Katsuo-bushi product compare to traditional Katsuo-bushi (P<0.1). Also, it is suggested that the longer the soaking time, the higher the moisture content and pH value. Keyword: Katsuo-bushi, liquid smoke, Duo trio method.   Ikan kayu atau lebih dikenal dengan Katsuo-bushi adalah sejenis ikan asap yang telah lama dikenal dan memiliki flavor yang khas yang biasanya digunakan pada masakan tradisional di Jepang.  Kelemahan ikan kayu yang ada di dunia dewasa ini adalah tingginya kandungan Polycyclic Aromatic Hydrocarbon (PAH) yang melebihi 10 ppb. Penelitian terkini (Berhimpon, dkk 2016) meneliti ikan kayu asap cair yang rendah PAH, tetapi belum diteliti tingkat kesukaan secara organoleptik. Penelitian ini adalah untuk mendapatkan ikan kayu asap cair yang rendah PAH tetapi disukai oleh konsumen. Tujuan penelitian ini ialah untuk mengetahui pengaruh konsentrasi asap cair dan lama perendaman terhadap mutu organoleptik ikan kayu asap cair yang dibuat dengan berbagai konsentrasi dan lama perendaman, dan dibandingkan dengan ikan kayu konvensional. Parameter pengamatan ialah analisa organoleptik dengan metode duo trio (Berhimpon, dkk. 2005), analisa kadar air dan pH (AOAC, 2005). Hasil penelitian ini menunjukkan bahwa ikan kayu yang direndam dalam asap cair dengan konsentrasi 2% dan 3% masing-masing selama 30 dan 10 menit berbeda sangat nyata (P<0,1) dengan ikan kayu konvensional. Sedangkan perlakuan yang lain sama dengan ikan kayu konvensional. Untuk analisa kadar air dan pH menunjukkan bahwa lama perendaman memberikan pengaruh yang nyata terhadap nilai kadar air dan pH dari ikan kayu asap cair, dimana semakin lama waktu perendaman dalam larutan asap cair maka semakin tinggi kadar air dan pH dari ikan kayu tersebut. Kata Kunci: Ikan kayu (Katsuo-bushi), asap cair, metode duo trio.
