Abstract
The study was conducted to detect and analyze quantitatively the formaldehyde concentration in smoked fishes sold in selected markets in Nueva Ecija. Samples were collected from the markets of San Jose City, Gapan City and Cabatuan City. Formaldehyde concentration was determined through spectrophotometric method. The absorption was compared to the Malaysia Standard for formaldehyde concentration in smoked products. The formaldehyde concentration per city and per species of smoked fish were also compared. Results showed that formaldehyde concentration in smoked fish ranged between 0.424 and 4.822 ppm. Highest concentration was recorded in Gapan City while lowest in Cabanatuan City. In terms of species of smoked fish, highest concentration was recorded in Galunggong. In general, the obtained formaldehyde concetration is significantly lower than the Malaysia Standard (5 ppm). This suggests that the smoked fish sold in the markets of selected cities in Nueva Ecija is safe for human consumption.
