Abstract
Formaldehyde is a chemical used as a preservative that is often used on corpses and research animals and is used as an antiseptic agent to kill viruses, bacteria, and fungi. The danger of formaldehyde chemicals contained in food can cause acute effects that arise that can attack the respiratory tract, digestion, headaches, hypertension (high blood pressure) and chronic effects in the form of irritation of the respiratory tract, vomiting, burning sensation in the throat and itching in the chest. Formaldehyde is often used in food use and if formaldehyde is consumed on a chronic basis it can cause cancer. The purpose of this study was to determine whether some types of salted fish sold in the traditional markets of Semendawai District III contain formaldehyde. on several types of salted fish sold at the Traditional Market of Semendawai District III. This research was conducted with qualitative and quantitative methods. In a qualitative test using chromic acid, the sample was tested positive for formaldehyde when the initial clear color turned purple after adding the chromic acid acid reagent, a qualitative test using KMnO4 tested positive for formaldehyde, marked by clear initial color after the KMnO4 drops turned pink. Followed by quantitative testing using Visible Spectrophotometry. The results of the qualitative and quantitative tests of all samples which amounted to 5 positive samples contained formaldehyde marked with a clear initial color and turned purple when chromatophenic acid reagent tests and pink when KMnO4 test. Quantitative results were obtained from salted fish content of 67,897 to -9,821 mg. The results of the One Way Anova analysis show a sig value of 0.00 which means that the longer the boiling can reduce the levels contained in salted fish. Keywords: Formaldehyde, Salted Fish, Visible Spectrophotometry.
