Study of Ofner's method for the determination of invert sugar.

چکیده
In a previous investigation Jackson and Mc Donald studied Ofner's method for the determination of invert sugar in sucrose. They modified the procedure and were thus able to increase the reproducibility of results when determining from 5 to 25 mg of invert sugar in the presence of sucrose. This method has now been applied to pure invert sugar and to sugar samples containing 5 mg or less of invert sugar in 10 g of sucrose. It has proved to be a suitable method for the analysis of high-grade refined sugars as well as for the determination of 25 mg or less of invert sugar alone. A table is given for the conversion of mill iliters of iodine consumed to milligrams of invert sugar present.
