Abstract

The tomato sauce is made from tomatoes that have been cooked and then added sugar, salt, vinegar and spices such as cloves and cinnamon, onions, celery and other vegetables are also frequently added to the tomato sauce and given the addition of preservatives. Commonly used preservative is sodium benzoate. This study aims to determine the content of sodium benzoate used in tomato sauce packaging spectrophotometrically by seeing how closely they match the requirements according to SNI 01-0222-1995 regulations on the use of the preservative sodium benzoate is less than 1000 mg/ml. The first step in this research is conducted with qualitative tests on samples using FeCl3 reagent yellowish red precipitate formed, subsequent assay using visible spectrophotometer. Determination of sodium benzoate in the sample is to seek maximum wavelength and operating time. Wavelength of 230 nm is obtained and the operating time of 3-10 minutes. The conditions used for the calibration curve and the readings of the assay sample . Based on the results obtained sodium benzoate in ketchup packaging A sample of 797,0193 mg/ml; B 847,7926 mg/ml; and C 865,4996 mg/ml, all samples met the requirements of SNI 01-0222-1995 on the use of the preservative sodium benzoate is less than 1000 mg/ml. These levels can be said to be safe for consumption by the public. Keywords : tomato sauce packaging, sodium benzoate, UV - Vis spectrophotometry
