Starch Determination Meter DPCZ-II

I. Principle of MeasurementStarch reacts with iodine to form an iodine-starch complex, which exhibits a distinctive color change. Branched-chain starch forms a brown-red complex with iodine, while linear...

Starch reacts with iodine to form a deep blue complex.

Under constant total starch content, the combination of these two

Starch dispersion solutions are mixed in varying proportions.

Under certain wavelengths and acidity conditions, with iodine

Effect, generates a series from purple to deep blue

Color, representing its different amylose and branching

Amylose content ratio, based on absorbance and

Starch concentration shows a linear relationship; measurement.

Content of amylose
