Santos Ave, Bicutan, Taguig City, Philippines This study evaluated the migration of total UV-absorbing contaminants (TACs) from commercially available low-density polyethylene (LDPE) bags commonly used by local eateries and street stalls in the Philippines to package fatty and oily foods. Forty-six (46) LDPE samples composing fifteen (15) brands were collected from public markets across Metro Manila and analyzed using a validated UV-Vis spectrophotometric method. Preliminary screening identified samples with low, mid, and high TACs absorbance levels for method validation. The method demonstrated limits of detection (LOD) and quantification (LOQ) of 0.009 and 0.021 AU, respectively, with repeatability and intermediate precision metrics meeting established criteria. Results revealed significant variability in TACs levels across brands and locations with 58.7% of samples exceeding the Philippine Food and Drug Administration's maximum allowable limit of 0.100 AU. The high non-compliance rate highlights possible inconsistencies in material quality and handling practices. These findings underscore the need for stricter regulatory oversight and enhanced quality control measures for LDPE materials used as food packaging. This study provides a reliable method for monitoring TACs migration and offers critical insights for ensuring the safety of food contact materials in the Philippine market, contributing significantly to food protection efforts. https://www.foodandnutritionjournal.org/volume13number2/assessment-of-total-uv-absorbing-contaminants-in-ldpe-food-packaging-from-philippine-markets/ Contaminants LDPE Oily Packaging Plastic TACs UV-Vis Spectrophotometry
