Abstract

Purpose of this research was to know formaldehyde content, pesticides (organochlorine and organofosfat), and molds on various type of dried salted fish. This research used survey methods, sampling and laboratory analysis. The fish used are salted siamese gourami fish (Trichogaster pectoralis), salted bagrid catfish (Hemibagrus nemurus), salted longjaw thryssa fish (Thryssa setirostris), salted snakehead fish (Channa striata) and salted fish anchovies (Stolephorus sp.). Result showed that salted snakehead fish (Channa striata) and salted anchovy fish (Stolephorus sp.) in August and September are positive to formaldehyde content. All tested samples were negative to pesticide residues. The result of molds test revealed that all samples still met National Food and Drug Agency (BPOM) RI 2009 standards which were less than 1x105 colonies/gram.

Abstract

The purposes of this research were to determine the chemical characteristics of siamese gourami (Trichogaster pectoralis) fish meal, and its application in steamed rice pempek. Different siamese gourami fish meal and tapioka starch ratio was added to steamed rice dought and the physicochemical and sensory characteristics of the end products were analysed. Physical variables product that were observed in the study included gel strength test and color test. Chemical variables observed were moisture, ash, fat, protein, carbohydrate, calcium, and phosphorus levels. Hedonic test was done on appearance, color, texture, aroma and flavor. The result showed, the gel strength value of steamed rice ranged from 181.1 gf to 451.9 gf, whiteness from 50.19 % to 67.96%, moisture content from 30.5% to 45.17%, ash content from 3.0% to 5.8%, protein content from 10.36% to 17.01%, fat content from 5.44% to 10.9%, carbohydrate content from 31.27% to 41.34%, calcium content from 26.58 mg/100 g to 58.35 mg/100 g, phosphorus from 14.43 mg/100g to 69.13 mg/100 g. Hedonic result for all attributes (appearance, aroma, texture, flavor, color) were ranged from dislike to intense like.

Abstract

The purpose of this research was to observed the effects of yellow velvetleaf fruit estrats on the characteristics fruit extracts on the characteristics of gelatin-chitosan edible film and its application in pempek. The ability of film to inhibit the spoilage of pempek was also studied. This research used a Randomized Block Design (RBD) in the first stage and Design Randomized Factorial (DRF) in the second stage with two-factor and two repetitions. Factors treatment consists of velvetleaf extract concentrations (0, 10, 20%) and the storage time (0, 1, 2 days). The first phase edible film was characterized basedon solubility, thickness, water vapor transmission and the percent extension, the second phase while their ability to protect pempek produk were assessed though the changes on water content, total volatile base-N (TVB-B), total plate count (TPC) yeasts and molds of the products during storage 2 days. The results of the first phase of research showed the addition of extract yellow velvetleaf no significant effect on the solubility, thickness and water vapor transmission while give the significant effect on the percent extension. The results of the second phase research showed the interaction between the addition of yellow velvetleaf extract and storage time significant effect on water content, total plate count (TPC) and yeast fungi while the total volatile base-N (TVB-N) effect is no significant effect. The best treatment of the first study, was A1 (Extra yellow velvetleaf 10%). Activity antimicrobe, Solubility, thickness, water vapor transmission and the percent extension of each is 3.75mm, 98.14%, 0.18 mm, 7.40 g/m2.24jam, 63.66%. The best treatment of the second study is A1B1 (extract yellow velvetleaf 0% and first day of storage time). Water content, total volatile base-N (TVB-N), total plate count (TPC) yeasts and molds, respectively 54.68%, 9.3 mg/100 g, 7.22x103 CFU/g, and 5.32x104 CFU/g.

Abstract

The purpose of the research was to know effect of variations temperature on changes in quality of low economic shredded fish during storage. This research used Randomized Block Design (RBD) and Factorial Randomized Block Design (FRBD) with two factors treatments and two replications. The factors were the storage temperatures (40 ºC, 50 ºC, and 60 ºC) and storage time (7, 14, 21, and 28 days). The parameters in this research included chemical and sensory characteristics. The results showed the interaction between storage with storage temperature were significant effect on the water activity, total plate count, total yeast and moulds, appearance, and odor. Based on the analysis of variance (p >0.05) shows that differences storage temperatures (40 ºC, 50 ºC, and 60 ºC) didn’t give significant effect on moisture, fat, protein, and carbohydrate content during 28 days storage while there was significant effect on ash content. Based on sensory test, appearance, odor, flavor, color, and texture scores were range 7; that means the product is still accepted by panelists.
