Detecting Furan: Conclusion

Results of the reaearch show that of all the eight samples analysed  using the HS-GC/MS method the brewed coffee was proved to have the highest levels of furan at 250 μg/L.

Table 6. Sample Analysis Results.

Amt. of Sample Furan Found No. Sample Details in ppb

Sample 1 Lab Coffee 0.67

Sample 2 Chocolate Flavored Milk (AKCF) 1.67

Sample 3 Espresso Coffee 45.18

Sample 4 Coffee Flavored Milk (AKC) 10.87

Sample 5 Cocoa Flavored Milk (AKK) 1.76

Sample 6 Energy Drink (milk based) (NAEM) 13.21

Sample 7 Brewed Coffee 36.59

Sample 8 Filtered Coffee 253.99

In conclusion, furan is rapidly and extensively absorbed from the intestine and the lung. It can pass through biological membranes and enter various organs. Experiments have shown that furan is carcinogenic to rats and mice, showing a dose-dependent increase in hepatocellular adenomas and carcinomas in both sexes. Furan has been classified as possibly carcinogenic for humans. However, preliminary exposure data suggest that the levels of furan found in foods are well below the levels that would cause harmful effects.

Until more is known, FDA recommends that consumers eat a balanced diet, choosing a variety of foods that are low in trans-fat and saturated fat, and rich in high-fibre grains, fruits, and vegetables. Under the circumstances described previously, the continuation of the research is desirable
for achieving safer and healthier foods
