游离脂肪酸（FFA）既是脂肪水解的产物，又是脂肪合成的底物，在脂质代谢中处于核心枢纽位置。FFA浓度与脂类代谢、糖代谢及内分泌功能密切相关，同时也可作为食品贮藏过程中品质变化的敏感指标。本试剂盒采用铜皂比色法测定FFA含量：在弱酸性条件下，FFA与铜盐反应生成有色铜皂复合物，该产物在715 nm处具有特征吸收峰，且在一定浓度范围内，游离脂肪酸含量与显色程度呈线性关系。通过测定715 nm处吸光度，即可定量计算样品中FFA含量。
Free fatty acids (FFA) are both the products of lipolysis and the substrates for lipogenesis, positioning them at the central hub of lipid metabolism. FFA concentrations are closely associated with lipid metabolism, glucose metabolism, and endocrine function, and also serve as sensitive indicators of quality changes during food storage. This kit employs the copper soap colorimetric method for the determination of FFA content. Under weakly acidic conditions, FFA reacts with copper salts to form a colored copper soap complex, which exhibits a characteristic absorption peak at 715 nm. Within a certain concentration range, the FFA content shows a linear relationship with the degree of color development. By measuring the absorbance at 715 nm, the FFA content in the sample can be quantitatively calculated.
