Product application
Take 0.25g (accurate to 0.1mg) of the sample after drying at 105 °C for 3h. Put 250ml of glass plug flask, add 36ml of glacial acetic acid and 4m1 of acetic anhydride, and warm to make a solution. Cool to room temperature, add 2 drops of crystal violet test solution (TS-74), and titrate to the blue-green endpoint with 0.1mol/L pechloric acid glacial acetic acid solution, and maintain for 30s without disappearing. At the same time, blank tests are carried out and necessary corrections are made. Perchloric acid per ml of 0.1mol/L is equivalent to 15.02mg of potassium sorbate (C6H7KO2).
It is used as a preservative and fungal agent in the food industry.
