The method employed is a literature review of both national and international indexed articles, with inclusion criteria for scientific articles related to the analysis of metanil yellow in food and beverages published in the last 10 years (2015–2025). Based on the literature review conducted, qualitative testing can be performed using Test Kits, Thin Layer Chromatography, UV-Vis Spectrophotometry, and FT-IR Spectroscopy, while quantitative analysis can be conducted using UV-Vis Spectrophotometry and High-Performance Liquid Chromatography (HPLC).]]>
