Nitrite scavenging activity and antiformation of mutagens from aminopyrene treated with nitrite by polysaccharides currently used in food industries

Abstract

The main purpose of this study was to investigate nitrite scavenging activity of polysaccharides used in food industries and antiformation of mutagens of aminopyrene treated with nitrite. The thirteen polysaccharides have been selected to be evaluated on their nitrite scavenging activity and antiformation of mutagen of aminopyrene-nitrite model using Ames test (without the addition of activating system). The results of this study suggested that all of polysaccharides had little or no nitrite scavenging activity. Agar, carboxymethylcellulose, guar gum, gum arabic, locust bean gum, methylcellulose 25 cps, 1500 cps, 4000 cps, and pectin could not inhibit the mutagenicity of aminopyrene-nitrite model; however, they increase the mutagenicity of this model. Carrageenan, sodium alginate, xanthan gum, and a-cellulose showed their inhibitory effect of mutagenicity of the model in addition methylcellulose 25 cps, 1500 cps, and 4000 cps were more firmly bound to aminopyrene than the others It was suggested that effect of polysaccharides on nitrite scavenging activity and antiformation depended on the type of fiber.
