Abstract

A low level of sanitation and hygiene applied by smoked fish processors in North Sulawesi can affect the quality and safety of the product itself. Interestingly, there is a huge market demand of smoked fish product in North Sulawesi. That is why  it is necessary to improve quality of smoked fish product by assisting the smoked fish processors. The program's target partners are located in Pontoh Village, Wori District, North Minahasa Regency which is geographically located on the coast Pontoh Village is categorized as a fishing community, which is about 50% classified as poor families and has a small business group of processing smoked fish. The aim of this program is to increase production, marketing and finance for small entrepreneurs in Pontoh Village, Wori District, North Minahasa Regency so they can be skilled and economically independent. The specific target of this activity is to produce smoked fish products that are superior in terms of taste and shelf life while providing business continuity and strong management. The method of implementation that will be applied to this program are 1) Training on how to produced smoked-fish product using good manufacturing practices  2) Assiting about sanitation and hygiene in every step of producing smoked fish; 3) Advising on management

Abstract

One of the protein molecules of fish scales is water soluble gelatin. Gelatin of fish scales could be best substitute of commercial available gelatin which derived from porcine and bovine. The purpose of this study was to determine the molecular structure of gelatin extracted from marine fish scale using Fourier transform infrared (FTIR) analysis, and to obtain the moisture content, pH and yield of gelatin. Samples were prepared from the wet and dried scales. As for the standard gelatin, the gelatin of the two samples are characterized with several types of amide groups. The two gelatin samples were slight different in absorption of wave length for amide A, B, I, II and III groups indicating the instability of the functional groups which may influence viscosity and gel strength. For the wet scales derived gelatin, the wave number absorption was found to be 3412 cm-1 (amide A), 2421 cm-1 (amide B), 1653 cm-1 (amide I), 1400 cm-1 (amide II), and 1001 cm-1 (amide III), while for the dried scales derived gelatin was 3435 cm-1 (amide A), 2920 cm-1 (amide B), 1635 cm-1 (amide I), 1404 cm-1 (amide II), and 1036 cm-1 (amide III). The wave number absorption of amide III of gelatin is smaller than the one of collagen, because gelatin is in form of single helix, not triple helix. The wet scales derived and dried scales derived gelatin show the moisture content of 15.0% and 13.7%, and yield of 2.33% and 2.43%, .respectively. For both samples, the pH value was 7.

Gelatin sisik ikan dapat menjadi pengganti terbaik dari gelatin komersial yang tersedia yang berasal dari babi dan sapi. Tujuan dari penelitian ini adalah untuk menentukan struktur molekul gelatin yang diekstrak dari sisik ikan laut menggunakan Analisis FTIR (Fourier Transform Infrared), dan untuk mendapatkan kadar air, pH dan rendemen gelatin. Sampel disiapkan dari sisik basah dan sisik kering. Adapun standar gelatin, gelatin dari kedua sampel ditandai dengan beberapa jenis gugus amida. Kedua sampel gelatin sedikit berbeda dalam penyerapan panjang gelombang untuk amida A, B, I, II dan III yang menunjukkan ketidakstabilan kelompok fungsional yang dapat mempengaruhi viskositas dan kekuatan gel. Untuk gelatin sisik basah, panjang gelombang serapan ditemukan pada 3412 cm-1 (amida A), 2421 cm-1 (amida B), 1653 cm-1 (amida I), 1400 cm-1 (amida II), and 1001 cm-1 (amida III), sedangkan untuk gelatin sisik kering adalah 3435 cm-1 (amida A), 2920 cm-1 (amida B), 1635 cm-1 (amida I), 1404 cm-1 (amida II), and 1036 cm-1 (amida III). Panjang gelombang serapan amida III pada gelatin lebih kecil dibanding kolagen, sehingga gelatin berbentuk single helix, bukan triple helix. Gelatin sisik basah dan sisik kering mengadung kadar air 15,0% dan 13,7%, rendemen 2,33% and 2,43%, secara berturut-turut. Untuk kedua sampel memiliki nilai pH 7.

Abstract

Tujuan penelitian yaitu: menentukan konsentrasi dan lama perendaman dalam larutan asap cair yang optimum melalui percobaan untuk mengaplikasikan asap cair hasil pirolisis cangkang pala pada pengawetan ikan julung. Hasil penelitian menunjukkan bahwa nilai Aw tertinggi pada  perendaman 90 menit dengan konsentrasi larutan asap cair 10 %. Kadar air tertinggi pada lama perendaman  90 menit dengan konsentrasi larutan asap cair  15 % yaitu 26,34 %. dan kadar protein tertinggi yaitu 54,23 % pada lama perendaman 30 menit pada konsentrasi larutan asap cair 10 % kadar lemak terendah 1,21 % pada lama perendaman 90 menit pada konsentrasi asap cair 5 % dan kadar abu terendah pada lama perendaman 60  menit dengan konsentrasi asap cair 10 % yaitu 1,12 %. Hasil penelitian julung asap cair pada lama perendaman 30 dengan konsentrasi 5 %, 10 % dan 15 % menunjukkan bahwa kandungan total PAH paling rendah dihasilkan pada konsentrasi larutan asap cair 5 % di ikuti oleh pengasapan cair dengan konsentrasi larutan asap cair 10 %, dan 15 %The purpose of this research is to determine the optimum concentration and soaking time in a liquid smoke solution through an experiment to apply liquid smoke from the pyrolysis of nutmeg shells to the preservation of julung fish. The results showed that the highest Aw value at 90 minutes immersion with a liquid smoke concentration of 10%. The highest water content in the 90 minute immersion with a liquid smoke concentration of 15% is 26.34%. and the highest protein content is 54.23% at 30 minutes soaking time at the concentration of liquid smoke solution 10% the lowest fat content is 1.21% at 90 minutes soaking time at 5% liquid smoke concentration and the lowest ash content at 60 minutes soaking time with concentration liquid smoke 10% which is 1.12%. The results of the liquid smoke rolls in the immersion period 30 with concentrations of 5%, 10% and 15% showed that the lowest total PAH content was produced at a concentration of 5% liquid smoke solution followed by liquid fuming with a concentration of liquid smoke solution of 10%, and 15%
