This study aims to determine the effect of fish bone gelatin addition on physical, chemical, and organoleptic characteristics of gelato. This research was done on three stages: fish bone gelatin extraction, gelato production and analysis. The treatment factor consists of concentration: 0%, 0.4%, 0.8% and 1.2% of fish bone gelatin additions. Data were analyzed by one way analysis of variant (ANOVA) at level 5% and then continued by Tukey HSD (Honestly Significant Different) test or Tukey’s range test. The result shown that fish bone gelatin addition has effect to organoleptic, physical, and chemical characteristics of gelato. The best concentration was 1.2% for fish bone gelatin addition. Gelato with concentration 1.2 % fish bone gelatin have texture, taste, colour, aroma and aftertaste range in netral until like slightly in organoleptic (hedonic) value range i.e between 2.62 until 3.70. This gelato have overrun, melting point and pH in 30.48%, 38.4 minutes and 6.6 respectively. It was contains 3.62% protein, 6.32% fat, and 15,62% sucrose. This nutrition contents was confirm with the Indonesian National for Standardization (SNI) for ice cream groups.

Penelitian ini bertujuan untuk melakukan ekstraksi gelatin dari tulang ikan patin menggunakan asam sitrat dan menganalisis karakteristik fisiko-kimianya. Ekstraksi gelatin melalui dua tahap yaitu tahap pre-treatment dengan asam sitrat dan ekstraksi utama dengan aquadest. Tahap pre-treatment dilakukan dengan variasi waktu yakni 24, 36, 48 dan 56 jam. Tahapan ekstraksi utama dilakukan pada suhu 45, 55, 65, dan 75°C. Hasil ekstraksi dilanjutkan dengan analisis keberadaan protein gelatin dengan metode SDS-PAGE. Analisis fisiko-kimia gelatin meliputi derajat keasaman (pH), rendemen, kekuatan gel, profil tekstur, viskositas, kadar air, kadar abu, kadar protein dan kadar lemak juga dilakukan. Hasil SDS-PGE gelatin perlakuan terbaik (yakni dengan pre-treatment 48 jam dan ekstraksi utama pada suhu 75°C) diketahui memiliki bobot molekul 162 kDa. Gelatin hasil ekstraksi terbaik memiliki rendemen sebesar 6,14%. Gelatin tulang ikan patin memiliki pH 4,46, kekuatan gel 364,19 bloom, daya kunyah sebesar 261,76 g dan viskositas 3,83 cP. Kadar proksimat gelatin tulang ikan patin meliputi kadar air, kadar abu, kadar protein dan kadar lemak masing-masing 7,72; 0,38; 58,70, dan 2,79%. Hasil penelitian juga menunjukan bahwa semakin tinggi suhu ekstraksi dan lamanya proses pre-treatment yang digunakan, maka bobot molekul protein menjadi semakin tinggi pula. Kesimpulannya, pre-treatment asam sitrat selama 48 jam dan ekstraksi utama pada suhu 75°C telah berhasil menunjukkan hasil yang paling baik dan dapat terkarakterisasi sifat fisik serta kimianya.Physical and Chemical Characteristics of Gelatin from Pangasius Catfish Bone with Pre-Treatment of Citric AcidThis research aimed to extract gelatin from Pangasius catfish bone using citric acid and then analyse its physicochemical characteristics. The extraction of gelatin was done in two stages soaking i.e pre-treatment with citric acid and main extraction by aquadest. Pre-treatment was done by soaking bones at 24, 36, 48 and 56 h, then the main extraction was done by soaked leached bones in temperature 45, 55, 65, and 75°C. The gelatin from catfish bone then was analyzed the presence of protein by SDS-PAGE and its physico-chemical including pH, yield, gel strength, texture profile, viscosity, moisture content, ash content, protein content, and fat content. Based on SDS-PAGE, fish bone gelatin had molecular weight of 162 kDa. The best extraction treatment (pre-treatment 48 h and main extraction at 75°C) produced 6.14% of gelatin yield. Gelatin of pangasius catfish bone had pH 4.46, gel strength of 353.76 bloom, chewing power of 261.76 g, and viscosity of 3.83 cP. Water, ash, protein and fat content was 7.72, 0.38, 58.70, and 2.79%, respectively. The higher extraction temperature and the longer time for pre-treatment process, the higher molecule weight of protein. As conclusion, the best treatment that was found in the sample with the pre-treatment at 48 h and the main extraction at 75˚C, was successfully characterized on its physicochemicals.•|•|•|•

Gelatin is one of the popular ingredients and additives in food industries. They have been applied in various roles, including stabilizers, thickeners, and emulsifiers. Bovine (cattle or cow) is one of the most widely used a source of gelatin. Unfortunately, they are still limited in particular considerations. For example, bovine gelatin is unacceptable in some Hindu communities. And the risks of Bovine Spongiform Encephalopathy (BSE) contamination, spreading, and outbreak related to bovine as a source. To challenge these limitations, poultry is another promising source. Current studies have found a similarity between poultry or chicken-based gelatin and bovine gelatin. However, investigation on the comparability of their gel strength is still rare. It is generally accepted that gel strength is the most essential characteristic of gelatin. This systematic review examined the gel strength between poultry gelatin and bovine gelatin. There were 795 papers screened, 29 full-text papers assessed, and 10 papers reviewed. The meta-analysis shows that chicken feet (CFG) and head (CHG) gelatin possessed a higher gel strength value than bovine gelatin. In contrast, the gel strength of chicken skin gelatin (CSG) and bovine gelatin did not differ significantly. The meta-analysis demonstrates that the gel strength of duck feet (DFG) and skin (DSG) gelatin is comparable with bovine gelatin. Thus, this study exposed the feasibility of CSG, DFG, and DSG, which can be the substitute for bovine gelatin.
