Abstract

Analysis of histamine content in processed bullet tuna (Auxis thazard) stew flesh can be carried out by Spectrophotometry method, using p- phenildiazonium sulfonate reagent. A qualitative, visual comparison of colour intensity of samples with reference colour scale of the standard solution concentration can be used to determine levels of histamine without the aid of a spectrophotometer. The histamine content is determined quantitatively by the standard curve regression equation (y= 0.003x–0.062) with determination coefficient value (R2= 0.938). The results showed that histamine content inprocessed bullet tuna (Auxis thazard) obtained: 46.9964; 40.3093; 34.4348; 28.9900 and 24.8862 mg/100g fish, at 0.5; 1.0; 1.5; 2.0 and 2.5% concentration of NaCl, respectively.

Abstract

The research on the effect of vinegar to histamine content in bullet tuna (Auxis rochei) has been done. Histamine content of quantitatively determined using a standard curve regression equation (y = 0.005 x - 0.046) with a price coefficient of determination (R2 = 0.926) is close to unity. The results showed levels of histamine in bullet tuna marinated in vinegar with variation concentrations of 5%, 10%, 15%, 20%, and 25% within 10 minutes, are 25.9099; 20.0408; 18.9671; 18.7108 and 18.6336 mg/100g respectively. While the levels of histamine in bullet tuna marinated in 25% of vinegar with variation of 10 minutes, 20 minutes, and 30 minutes, are 18.6336; 16.0550; and 15.5246 mg/100g respectively.
