| Background and Objective: Furan is classified as a probable human carcinogen (group 2B) by the International Agency for Research on Cancer. The Joint FAO/WHO Expert Committee (JECFA) reported in 2010 that the maximum dietary exposure to furan is 2 µg/kg body weight per day. The objective of this study was to determine the furanic-compounds content of baby-foods in Tehran market, using the microextraction technique, based on headspace liquid-phase micro-extraction/mass spectrometry (HS-LPME-GC/MS) and investigate the effects of two preparation temperatures (45 and 70˚C) on their concentrations.
Materials and Methods: In order to optimize the factors affecting furanic compound extraction using the response surface methodology and central composite design, 30 experiments for 4 variables at 5 levels were performed. To validate the proposed method merit figures of the method were determined. Furanic compounds from 35 different baby-food samples (powdered, fruit puree, baby drinks, and ready-soups) marketed in Tehran were extracted by HS-LPME at optimal extraction conditions (temperature: 40°C, time: 15 min, stirrer rate: 700 rpm, salt: 1 gram). The samples were prepared at 2 temperatures, namely, 45°C and 70°C.
Results: Merit figures of the proposed method were in some cases better than those of previous methods. There were statistically significant differences (p<0.05) among the different baby-foods with regard to furan concentration. Preparation of the samples at both temperatures brought about a reduction in the furan content, with an increase in the 2,5-dimethylfuran content (p < 0.05). The lowest and highest total furanic compound concentrations were 159.24 ± 7.96 µg kg-1 and 624.64 ± 31.23 µg kg-1 in powdered baby-foods and baby soups, respectively.
Conclusion: In the present work, a simple and fast micro-extraction method (HS-LPME) for extraction and pre-concentration of furanic compounds in baby-foods was developed and validated. The effective parameters on performance of the micro-extraction process were optimized. Differences among the different babay food samples with regard to furanic compounds contents are due to different ingredients used in their production.
