Abstract
To establish a method of detecting gelatin solution viscosity at the different steps with different concentration during its processing.The sample concentration was examined by HZ-10B hydrometer,and the viscosity was examined by ND-1 Brookfield Viscosity meter.Finally the viscosity value was corrected based on concentration with the Concentration Dependency Graph of Gelatin Solution Viscosity.Results showed that all the calibration curves in the graph had good linearity at the second degree.The developed method exhibited good linearity over the range from 30.0 mg/mL to 60.0 mg/mL with correlation coefficients above 0.99.The average recovery rate for corrected viscosity was 100.4％.This method was repeatable and fast,which was suitable for viscosity correction based on concentration at different process steps and different concentrations of gelatin solution.关键词
