Use "erythrodextrin" in a sentence
"Brukner regards the red color as resulting from a mixture of erythrodextrin, and the greater solubility of this substance in water."
"If a mixture of filtered potato starch paste and erythrodextrin is dried in a watch glass covered with a thin pellicle of collodion, and a drop of iodine solution placed on the latter, it penetrates very slowly through the pellicle, the dextrin becoming first tinctured with red, and the granulose afterward with blue."
"If, on the other hand, no erythrodextrin is used, the diffusion of the iodine causes at once simply a blue coloring."
