Keywords:Raw Tofu, Formalin, Traditional Market, Spectrophotometry UV-Vis
Consuming tofu that using formalin continuously will cause long and short term bad effect to human body. Long term effect can cause cancer. Beside, short term effect is skin irritation, nausea, vomiting, diarrhea and shortness breath. To know the content of formalin levels in raw tofu on Puruk Cahu Traditional Market with quantitative analysis method using Spectrophotometry UV-Vis and to compare formalin levels in some raw tofu samples.This research uses Cross Sectional method. Sample research is raw tofu that was found in Puruk Cahu Traditional Markets. In this research, using a piece of raw tofu from different markets. Data was collected by using Purposive Sampling. Analysis formalin levels was using Spectrophotometry UV-Vis to determine the formalin levels in raw tofu. In qualitative analysis with KMnO4 and fehling test, all samples shown positive results. In quantitative analysis of formalin levels on Market Sample B is 10.72 mg/L, Market Sample H is 11.24 mg/L, and Market Sample Hi is 8.450 mg/L. The difference of sampling location has no effect to the formalin levels (p = 0.07). The result of analysis formalin levels in raw tofu from Hungan Market higher than Bahitom Market and Puruk Cahu Hilir Market. This case is absolutely does not fit the regulation of Health Ministry of Indonesia No. 722/Menkes/Per/IX/1988 that states no formalin is allowed in food product.
