“…One case in point is the Brazilian drink cachaça, where the sugar comes from previously burned crops. Like other ingredients (cereal grain, grapes, fruits), sugar can also be contaminated by environmental pollution and human activities such as the use of lubricants in harvesting machinery …”

“…Like other ingredients (cereal grain, grapes, fruits), sugar can also be contaminated by environmental pollution and human activities such as the use of lubricants in harvesting machinery. 6 The main sources of PAHs in coffee grain and tea leaves are drying and roasting. 7 Juices and some soft drinks are made from fruits that can also be contaminated with PAHs from the environment (particularly if they are made from unpeeled fruit because PAHs can easily adhere to fruit peel and wax).…”

“…As PAHs are typically present at very low levels in drinks, an analyte enrichment step facilitates their determination. Polycyclic aromatic hydrocarbons have been extracted from drinks by using liquid-liquid extraction, 9,10 Soxhlet extraction, 11 microwave-assisted extraction, [12][13][14] solid-liquid extraction, 6,15 solid-phase extraction (SPE), [16][17][18] solid-phase microextraction (SPME), 19 stir-bar sorptive, 20 and QuEChERS. 21 Polycyclic aromatic hydrocarbons are usually determined by high-performance liquid chromatography (HPLC) or gas chromatography (GC).…”

This paper describes the development of a multiple dispersive liquid‐liquid microextraction method for the determination of fifteen polycyclic aromatic hydrocarbons in samples of Brazilian sugar cane spirit (known as cachaça) with separation and detection by GC‐MS. The results obtained with the multiple extraction approach were compared to those obtained with the conventional dispersive liquid‐liquid microextraction method using the same sample. Sample dilution and solvent volume were optimized using the response surface methodology. The coefficient of determination (R2) for the multiple dispersive liquid‐liquid microextraction method varied from 0.9939 to 0.9999. The limits of detection ranged from 0.06 to 1.5 μg L−1 and precision from 12 and 22%. The recovery values obtained with the proposed method ranged from 84 to 116%. The sum of the polycyclic aromatic hydrocarbons concentrations in six samples ranged from 0.65 to 12.2 μg L−1. Multiple dispersive liquid‐liquid microextraction was shown to be efficient in relation to compensating the matrix effects due to variations in the sample composition and the extraction parameters showed greater robustness compared to the conventional dispersive liquid‐liquid microextraction method, since it simulates an exhaustive extraction.
