title: [Assessing the content of formaldehyde in vermicelli in Changsha market].
abstract: In order to better supervise food safety for the residents, the extent of formaldehyde in vermicelli sold on Changsha market was assessed by the acetyl acetone colorimetry method. Results showed that among 106 samples, 61 were formaldehyde positive. The positive rate was 57.55% (61/106). The content of formaldehyde ranged from 0.011 mg/kg to 2.859 mg/kg, indicating severe contamination of vermicellis by formaldehyde in Changsha market and therefore, the food safety supervision work should be strengthened.
