Abstract

Optimization of Several Tapioca Flours in Patin Fish Nuget on Sensory Characteristic Through Response Surface Method Desmelati1 dan Rita Hayati 2 1Staf Pengajar UNRI, Pekanbaru2Staf Pengajar Unsyiah, Darussalam Nanggroe Aceh Darussalam ABSTRACT Result of the study showed that optimum region for nugget production using wheat flour, tapioca flour and corn flour were 1.3 – 10.54%, 1.98 – 4.30%, and 1.18 –11.89%, respectively.  Three formulations were selected for validation study.  Two formulation were from acceptance region (F1=0.37 of wheat flour, 0.46 tapioca flour, 0.17 corn flour, F2 =0.37 of wheat flour, 0.40 tapioca flour, 0.22 corn flour), and one formulation from rejection region (F3 =12.5 of wheat flour, 75 tapioca flour, and 12.5 corn flour). The validation of the three optimum points using sensory evaluation showed that formulation F1 was most acceptable followed by F2 and F3. There was significant difference (P≤0.05) between F1 and F2 when compared to F3, thus model equation was able to predict the optimum points.

Abstract

The research was conducted to observe the consumer acceptance on thesmoke flavoured fish Selais (Cryptoperus bicirchis). The fresh fish was preparedby eviscerated and washed it with clean freshwater. The fish was soaked in liquidsmoke solution at the concentration of 2%, 4%, 6%, or 8% for 30, 60, or 90minutes. Then, the fish was dried in the artificial dryer at temperature 50 – 60 0Cuntil the weight was reduced up to 70% of the initial weight. The smoke flavoredfish yielded was evaluated by determining their consumer acceptance, pH value,content of total acid and content of total phenol. The result showed that the fishsoaked in the liquid smoke at the concentration of 6% for 60 minutes is the mostlyaccepted by consumers, indicated on the highest value of consistence, texture,odor and flavor. The pH value, content of total acid and content of total phenol are6,40, 0,269%, and 0,84%, respectively.Keywords: consumer acceptance, Cryptoperus bicirchis, liquid smoke, andsmoke flavoured fish

Abstract

Shrimp paste is a source of protein because the protein of shrimp paste has a high protein (15-20 g/100 g). However, shrimp paste is only consumed as a flavor and seasoning mixture. The study was aimed to determine the quality of organoleptic and chemical of shrimp paste using the difference of salt and cooking time. The used method was an experimental method with a factorial Completely Randomized Design (CRD) consisting of 3 treatments, namely A1 (10 g salt), A2 (15 g salt) and A3 (20 g salt). Meanwhile, cooking time was 30 minutes, 45 minutes, and 60 minutes. The tested parameters were organoleptic (flavor, odor, texture, and appearance), proximate (moisture, ash, protein, and fat), and pH. The results showed that the interaction between 15 g salt and 45 minutes of cooking time was the best treatment with the organoleptic of 7.29 flavor (shrimp taste slightly reduced, less salty), 7.59 odor (the specific odor of shrimp paste), 7.21 texture (thick, homogenous, soft), 7.63 appearance (blackish brown). The proximate of shrimp paste was 38.12% moisture, 3.05% ash, 9.68% protein, 0.72% fat, and 7.05 pH.

Abstract

The purpose of this research was to determine the chemical quality and consumer acceptance of the staple fish sausage fortified with natural dyes, namely carrot extract and red spinach extract. The research method used was experimental design (CRD), as the treatment was S0 (Jelawat fish meat). ), S1 (Jelawat fish meat added 20% red spinach extract), S2 (Jelawat fish meat added 20% carrot extract). From the results of the study of the preference test, it is known that the Jelawat  fish sausage with the addition of 20% carrot extract (S2) was preferred by consumers with a percentage (87.50%) with very like criteria and percentage (6.25%) like criteria. Organoleptic values are taste (8.0), aroma (8.5), appearance (8.3) and texture (8.6). The nutritional content of Jelawat sausage added with carrot extract was higher than the other treatments, with protein content (15.43%) moisture content (55.32%) fat content (2.43%) ash content (6.19%) and carbohydrate content (20.63%). The characteristics of the sausage are thick and brass colored, fishy aroma and carrot aroma is more dominant, fish taste is slightly sweet and carrot-like, while the texture is dense and elastic.

Abstract

This study aims to determine the characteristics of biscuit quality with the addition of nanocalcium from the sembilang fish bone (Paraplotosus albilabris). The method used is non factorial completely randomized design with the treatment used in this study, namely the addition of nanocalcium from 4 levels, namely N0 (control: biscuits without the addition of nanocalsium), N1 (addition of 5% nanocalcium), N2 (addition of 10% nanocalsium ), N3 (addition of 15% nanocalcium). The parameters tested were organoleptic and proximate. The results of the study showed that the addition of 15% nanocalcium in Sembilang fish biscuits was the best treatment most panelists liked. Appearance characteristics are brilliant, intact and specific to fish biscuits, non-fishy aroma, and brittle and dense texture, with water content of 5.78%, ash content of 5.10%, fat content of 24.59%, protein content 6.82%, carbohydrate levels 57.71%, phosphorus levels 0.57% and calcium levels 14.14%.
