Abstract

The production of catfish in East Java in recent years increased significantly from 96,337.2 tons in 2014, to 113,070,4 tons in 2015. The high production impact on difficulties of farmers in some areas in marketing their crops, consequently many farmers lose money because feedstocks continue to go while the harvest difficulties sales. One way to increase market interest is by processing it into salted fish products trough salting method, there are two kinds of salting methods, including Wet salting and Dry salting. However, not all salting techniques produce a guaranteed quality product, this is due to the absence of a definite dose for the number of ingredients used, so determining the right NaCl concentration is essential to create a high quality dried salted fish product. The aim of this research is to know the effect of Salting method and different NaCl concentrations on the quality of dried catfish. This research uses the experimental method with Randomized Block Design (RBD) pattern factorial. The factor I: salting method consisting of Z1: Dry salting Z2: Wet salting. Factor II: NaCl concentration consisting of M1: 15%, M2: 25%, M3: 35%, M4: 45% So that there are 8 treatment variables, and each repeated 3 times so that there are 24 treatments. The parameters tested include NaCl, water, ash insoluble in acid, total plate count, protein, fat, and organoleptic (taste, appearance, aromatic, texture). The results of this study indicate that there is an interaction between the use of different types of salt methods and NaCl concentration on NaCl content, water, ash insoluble in acid, total plate count, and organoleptic taste. But there is no interaction with parameters protein, fat, organoleptic appearance, aromatic, and texture. Based on the Physico-chemical and organoleptic properties of dried salted catfish we found the best total treatment on Z1M4 (Dry salting: NaCl 45% concentration) with NaCl 15.44%, Water 16.67%, Ash Insoluble in Acid 0.21%, Total Plate Count 1.1 x 104, Protein 25.27%, Fat 6.06%, Organoleptic (taste) 5, Organoleptic (Appearance) 7.08, Organoleptic (Aromatic) 6.92, Organoleptic (Texture) 7.67.

Abstract

Gelatin is a protein obtained from animal collagen tissue found in warts, bones, and connective tissue that is hydrolyzed acidic or basic. The purpose of this study was to determine the different effects of HCl and acetic acid and different extraction temperatures on the production of local rabbit skin gelatin so that the best treatment was obtained in producing gelatin and to determine the effectiveness of local rabbit skin gelatin in rabbit meatball processing. This research was conducted in two stages. The first stage uses a nested random design, namely the extraction of gelatin from the local rabbit skin with different types of acids (HCl 3% and acetic acid 3%) and extraction temperature (50 °C, 60 °C, 70 °C and 80 °C). The parameters observed were yield, moisture content, ash content, protein content, viscosity, pH, and color. The best treatment of Local rabbit skin gelatin based on the SNI approach is in the P1T3 treatment, that treatment soaking with acetic acid and extraction temperature of 70 °C with a yield value of 13.11%, moisture content 5.503%, ash content 1.143%, protein content 63.49%, viscosity 4.466 cP, gel strength 210.532 grams Bloom, and pH 3,967. The second step was making meatballs by comparing the addition of gelatin from local rabbit skin extraction with the best treatment of 3%, commercial gelatin 3%, and without gelatin. The parameters observed included protein content, ash content, moisture content, fat content, texture, and organoleptic. Based on observations of the addition of gelatin in rabbit bakso, increasing the value of protein content, texture, and ash content in bakso while the water and fat content in bakso decreased with the addition of gelatin.

Abstract

This research studied the effect of natural colorant (turmeric filtrate) additions compared to synthetic colorant (Tartrazine) additions in taro starch-based edible film on the quality of dodol that substituted with seaweed. This research used a Randomized Block Design with Orthogonal Contrast. The treatment factor consist of turmeric filtrate additions in 1%, 2%, 3%, Tartrazin additions in 0,003%, 0,005%, 0,007% and without colorant as control treatment. Parameters that analyzed consist of thickness, color, transparency, tensile strength, elongation, water vapor transmission rate of edible film, moisture content, fat content, total plate count, texture and organoleptic value of dodol at the 0, 3rd, 6th day of storage. The research result shows that the additions of turmeric filtrate had an effect on increasing thickness, tensile strength, transparency, brightness (L), yellowness (b+), and decreasing the elongation and WVTR of edible film. Meanwhile, the additions of Tartrazin had an effect on increasing transparency, brightness (L), and yellowness (b+). The results of moisture content, fat content, TPC, and texture of dodol showed that the addition of turmeric filtrate is better to maintain the quality of dodol during storage. Additions of 3% turmeric filtrate as the best treatment, has 30.24% and 31.40% in moisture content, 1.16% and 0.97% in fat content, 4.0x103 CFU/g and 0.9x104 CFU/g in TPC, 15.30 N/mm and 14.03 N/mm in texture, 3.53 and 3.63 in color organoleptic value, 3.65 and 3.60 in aroma value and 3.75 and 3.73 in taste value during the 3rd and 6th day of storage.
