Abstract

Pindang is a semi-dried product which relatively short lasting products. Due to the rapid formation of histamine and bacterial enzyme activities contained in the fish, it is necessary to study and identify the histamine levels either on fresh tuna or in its pindang. This study aims to analyze histamine and histamine-forming bacteria in processed pindang tuna (A. rochei). Fresh tuna (A. rochei) was obtained from TPI Cisolok Palabuhanratu. The fish was processed according to pindang badeng method (20% salt added, boiled for 8 hours). The product then stored at room temperature and observed for 0,8,16,24 and 32 hours. Analysis were conducted through chemical (histamine and TVB) and microbiological test (TPC, identification of bacteria, histamine levels in bacteria). The results showed that the stored pindang for 32 hours can reactivate the production of histamine and increase their levels significantly. This is consistent with the increase on the value of TVB and TPC in pindang products. Six types of histamine-forming bacteria found on pindang tuna that are P. vulgaris, H. alvei, M. Morganii, E. aerogenes, K. oxytoca, K. pneumoniae. Activity test results showed that K. pneumoniae and H. alvei form the highest and the lowest levels of histamine formation respectively.Keywords: Histamine, bacterial, boiled tuna (Auxis rochei)

Abstract

Fish fillet is one of fisheries products that easily deteriorated; hence handling techniques are needed to maintain the freshness. Ultrasonic wave have been widely applied to some of food products for maintaining freshness through microbial inactivation, however the ultrasonic application to fisheries products has not been reported. The purpose of this study was to analyze the effect of ultrasonic wave on fish freshness. The stages of the study were sample preparation, sonication, freshness parameters examination and histology observation. Ultrasonic wave did not affectthe organoleptic value and the TVB, but affected the pH value and the TPC. The sample in which the TPC value was found significantly different, were further observed after 48 and 96 hours storage. The result showed that the TPC value of sonicated sample for 9 minutes was lower to that of without sonication. Histology analysis showed, however, sonication made the structure of muscle fiber less compact and deformation of myomer was found.
