Abstract
ABSTRACT The use of formalin non-food preservatives in food is now widely used. One of the methods used by fish traders in the preservation process is to use formaldehyde to prevent the process of spoilage and deterioration of fish quality by microorganisms. Formalin can have short and long term effects on health. The formaldehyde content in fish can be identified by qualitative and quantitative tests. Formalin qualitative test methods that have a high degree of accuracy and specificity in fresh fish samples are currently not reported. Therefore, research is conducted which aims to determine the most accurate and appropriate formalin qualitative method for the identification of formaldehyde on mackerel tuna samples. This study uses 5 qualitative test methods including K10H8O8S2, Tollens, KMnO4 0.1 N, Schiff, and Fehling on tuna fish samples sold in several Yogyakarta Traditional Markets. Based on the results of the study, the sensitivity level of the 5 formalin qualitative test methods on the 15 highest mackerel tuna samples was the Schiff reagent method.
