- Method Overview
This method is based on GB 12752-2010 National Food Safety Standard – Food Additive Vitamin B₂(Riboflavin). After dissolving vitamin B₂, it is diluted with sodium acetate solution, and a 1cm quartz cuvette is used for spectral scanning to determine the maximum absorption peak. The absorbance ratio at 375nm to that at 267nm should be 0.31~0.33, and the absorbance ratio at 222nm to that at 267nm should be 0.36~0.39.
