Abstract

Central Java is popular for soybean tofu and one of its diversification product is ‘tahu bakso’which is very famous in Central Java especially Semarang. Utilisation of nile fish meat can support fish protein intake by community as well as for promoting local protein resource. The aims of this study was to observe the effect of different concentration of fish meat on physical, chemical and sensory characteristic of ‘tahu bakso’. The parameters evaluated include texture (hardness, deformation, gel strength), proximate (protein, fat, carbohydrate, ash and water), and sensory (hedonic test) of the product resulted. This study used experimental laboratory by using Completely Randomised Design with Anova (p<0,05). The treatments covers: different concentration of fish meat (30%, 40% and 50%). Treatment with highest hardness and gel strength was performed by 30% concentration with the value of 530.88 g.cm. Whereas treatment 40% concentration has highest deformation of 23.47 mm, and has no significant different to 50% concentration. Based on analysis of variance, different concentration of fish meat gave significant effect on characteristic of proximate especially on protein and fat (p<0.05) but has no significant effect on water and ash content (p>0.05). Different concentration of fish meat has no significant effect on hedonic of ‘tahu bakso’ resulted. Overall ‘tahu bakso’ made from nile meat with 50% concentration is considered to be the most preferred by panelist, but the overall value has no significant different to 40% concentration. Therefore, it is concluded that concentration 40% of fish meat is considered as the best treatment for producing ‘tahu bakso’ with respect to texture, nutrition, sensory attributes.

Abstract

Freshness quality is considered as an important factor in determining overall quality of particular fish product items. The degree to which the freshness quality of the items meets the consumer’s expectation concerning freshness quality will greatly affect whether the fisheries product item will be purchased again or not. Considering the importance of fish freshness quality, many methods have been proposed to evaluate fish freshness including physical, chemical and sensory methods. The K value is one of  the chemical methods widely used , especially in Japan, as a fish freshness index to evaluate the quality change of raw fish. Tuna has been regarded as a palatable and valuable fish species and its freshness is  the  concern of many  researchers. This study is aimed at investigating the freshness change of yellowfin tuna (Thunnus albacares) during storage at low temperatures (10oC, 5oC and 0oC) by measuring the K value of the fish. Observation on the changes of ATP and its related compounds during storage was also carried out. The result of the study shows that the freshness of yellowfin tuna as measured by K value, changed in different patterns depending on the storage temperatures. The higher the temperature of storage the faster was the decrease in freshness of yellowfin tuna. It was also observed that yellowfin tuna could be eaten raw up to 1 day, 2 days and 4 days storage at temperature of 10º C, 5º C and 0º C, respectively. Storage temperature of 0º C is recommended for its preservation in chilled state. The use of HPLC allows for each of ATP-related compounds to be determined quantitatively.The Ki value is more appropriate for measuring fish freshness obtained more than 24 hours after death

Abstract

Four tropical fish species, Thunnus albacares (Yellowfin tuna), Ephinephelus striatus (Nassau Grouper), Cyprinus carpio (Carp), and Osphronemus gourami (Gouramy), were assayed for oxidation reduction potental (Eh) and pH in different temperature,i.e.  ambient and chilled temperature.  Every species has different pattern of Eh and pH values. Eh values of tropical freshwater fish were higher than tropical marine fish, however pH values  four tropical fish have same trend. The rates of the Eh and pH changing in four tropical fish were faster at ambient storage and they were slower at chilled storage. The present study also demonstrated the relationship between Eh and pH.

Abstract

Some traditional fish products in Indonesia have potential opportunity for global market, such as fish crackers, dried fish, ikan kayu (‘katsuobushi’) and dried pempek (traditional fish product from Palembang). Study on such products based on its glass transition temperature is still rare. On the other hand, glass transition phases of dried product play an important role in determining food stability because it can give an overview of physicochemical properties of the products. Using its glass transition temperature, dried fish product can be estimated for its shelf life. The purposes of this research are to observe the relation between some physicochemical properties of glass transition temperature of some dried fish products and its water content/water activity to the self life of the products. Dried fish products used were: fish cracker, dried-salted fish, ikan kayu (katsuobushi), fufu (very dried-smoked fish) and dried pempek. The samples were taken from different area in Indonesia (Cilacap, Palembang, and Sulawesi). The sample were taken using purposive sampling method. The method used for analysis of glass transition temperature was DSC method (Differential Scanning Calorimetry), and for water content and water activity were analysed using Aw meter and Moisture analyzer. All samples were analyzed in duplo. Research method used was experimental laboratory with research design of Completely Randomised Design. The experiment was conducted from August 2008 to December 2008 at Fish Product Processing Laboratory, Fisheries Department, Faculty of Fisheries and Marine Science – Diponegoro University, Food Engineering Laboratory – SQU, Oman. The results showed that different sample with different characteristics on physicochemical properties give different in water activity and also water content. The lowest water activity was performed by dried pempek. Glass transition temperature (Tg) of the products was very depend on the water content. The Tg of samples was ranged between 38.4oC – 76.4oC. The water content of the products ranged between 8.28%-37.28%. The Aw of the product was ranged between 0.57 – 0.87.

Abstract

Fisheries products are regarded as  perishable food. Fresh prawn is one of the most valuable fisheries products and its demand increases especially in developed countries. Handling and preserving of fresh prawn has been investigated to keep the quality. Glyroxyl has been successfully used as decontamination agent in the fish sector in the Netherlands. Apart from its use as decontamination agent, glyroxyl has been proved to be an efficient disinfectant. Due to its safe character, it is allowed to put glyroxyl in foodstuff directly, provided that the prescribed concentration is respected. This study is aimed to investigate the effect of different concentration of glyroxyl (0, 0.3 and 0.5%) on the preservation of fresh prawn. The sample used was white shrimp prawn (Penaeus monodon). The samples were soaked in glyroxyl solution with different concentrations. The analyses were conducted for organoleptic, Total Plate Count (TPC) and E. coli at 0 and 3 days storage at refrigerated temperature. The results showed that the use of glyroxyl solution (0%, 0.3% and 0.5%) has no effect on the organoleptic parameters of the sample (appearance, color and flesh). However, after 3 days of storage the effect of glyroxcyl became apparent especially for 0 % glyroxcyl treatment. The number of E. coli showed that application of glyroxyl could prevent the growth of E. coli and reduce the number of E. coli in the samples. In addition the E. coli obtained was less than number < 3 / < 3 in all samples after 3 days storage. Increase in glyroxyl concentration resulted in the decrease of bacterial number (TPC) both for 0 and 3 days storage
