  • Method for determining turbidity point and free carbohydrate buffer coefficient of iron-carbohydrate complex
    Patent number: 8679851
    Abstract: A method for determining a turbidity point and a free carbohydrate buffer coefficient of an iron-carbohydrate complex. The method includes: (1) contacting the complex with an acid; (2) determining hydrogen ion concentrations and solution turbidities of the complex in acid degradation; and (3) mathematically fitting the data, to obtain the turbidity point of the complex and the free carbohydrate buffer coefficient through mathematical treatment. A method for evaluating the safety of the iron-carbohydrate complex with the turbidity point and the free carbohydrate buffer coefficient.
