Fish is a food material that has high protein content, which cause fast decay by microorganism. Because of that, it needs a preservation process. One of preservative material used is formaline. Formaline is a chemical substance that used for fish preserving because it easy to find and has low cost. Qualitative analysis of formaline used potassium permanganate and chromatophic acid while quantitative analysis used High Performance Liquid (HPLC) and protein analysis used Kjeldahl method. The results showed that from 12 samples of fish all of the samples positive contains formaline which was 6.3352 - 12.2196 mg/Kg and protein in fish was 14.22 - 16.34%. The analysis result of formaline showed that some fish sample were exceed standard of International Program on Chemical Safety (IPCS) in 2002. Acoording to the research result there is no correlation between the content of protein on the fish.

Chemical insecticides have been widely employed for effective controlling of insect, but their indiscriminate use may create health hazards due to toxic residue that may persist on broccoli. The aims of this study was to analyze the levels of pesticide residues in broccoli with and without rinse with normal and hot water. Diazinon, chlorpyrifos and cypermethrin residues in broccoli were analyzed by gas chromatography, phosphate content by UV – Vis spectrophotometry and and Argentometry titration for chloride. The results showed that concentration of diazinon was ranged from 0.4321 to 0.4509 mg/kg, while residues of chlorpyrifos and cypermethrin were not detected. Normal and hot water rinse treatment could reduce 12.5 – 76.2% and 79.2 – 89.9% of diazinon residue, respectively. Based on MRL, the level of diazinon residue was under the standard (0.5 mg/kg). The rinse water treatment for phosphate were in the range of 2.2385 – 6.9725 ppm (normal water) and 46.3305 – 49.0825 ppm (hot water), while the chloride concentration were 0 – 0.1258 ppm (normal water) and 0.6296 – 1.0073 ppm (hot water). It could be concluded that hot water rinse treatment was effectively reduce the level pesticide residues in broccoli.
