Abstract
Fish is a source of protein and export commodities that are easily decayed compared to meat, fruit and vegetable products, so it is necessary to add preservatives so that the fish can last longer. The use of formalin as a preservative for salted fish is clearly prohibited according to PERMENKES No.33 of 2012 concerning Additional Materials Food because it can cause cancer in humans. This study aims to determine the presence or absence of formalin content in salted fish. Samples taken were 5 samples of jambal salted fish taken from the Jebres District Market. This study used a spectrophotometry UV-Vis with 0.5% Cromatofat Acid reagent. Based on the results of qualitative tests of formalin content in 5 samples taken in the market area of Jebres Subdistrict with 0.5% Chromatofat Acid reaction. The results showed a qualitative test of 5 positive samples containing formaldehyde, marked with a purple solution. Quantitative tests were carried out using the spectrophotometer UV-Vis 1800 shimadzu The results showed that the maximum wavelength value obtained was 594 nm with a linear regression equation y = 0.0306 + 0.1905 from the quantitative test showing 5 samples identified as formaldehyde. The level of sample A is 0.1419% ± 0.0028, the level of sample B is 0.1518% ± 0.0020, the level of sample C is 0.1238% ± 0.0003, the level of sample D is 0.1244% ± 0, 0031, Level E sample is 0.1655% ± 0.0043. Keywords: Salted Fish, Formaldehyde, Chromatofat Acid, Spectrophotometry UVVi
