Abstract


Shrimp paste is a fermentation product of shrimp and has a distinctive smell and taste. The paste is made from a mixture of shrimp, fish salt and brown sugar. The purpose of this study was to determine the effect of sugar concentrations on the chemical, physical, microbiological and sensory characteristics of shrimp paste. Five differentconcentrations of brown sugar (0; 7.5; 10, and 12.5%) were applied. The shrimp paste was analyzed for their protein content, water content, amino acids, salinity, total sugar content, pH, colour test, viability of LAB  and sensory. The sugar concentration significantly affected protein content, water content, total sugar, color, salt and organoleptic (p<0.05), but did not significantly affect on the water content, pH and LAB (p>0.05). The protein levels decreased with the increasing of sugar concentration. The brightness (L*) and redness (a*) were slightly decrease with the increasing of sugar concentration. The shrimp amino acid was dominated by glutamate acid, however, the concentration of amino acids decreased with the increasing concentration of the sugar. Addition of sugar to the shrimp paste improved the acceptance of the panelist, resulting higher score as compared to that of control. The best treatment in this study was the shrimp paste added with 10% sugar having the protein content 29.084%; water content 34.11%;  sugar content 15.37%, pH 6.97; L 46.52; salt 13.63%; glutamate acid 23115.83 mg/kg, BAL <10 log CFU/mL and total organoleptic value 8.
