White Dextrin are prepared by heat treatment in presence of chemicals to suitably modify characteristics and properties of starch. Unlike starch dextrin are soluble in water. The severity of the treatment determines the degree of solubility, which is the basis of classifying or grading dextrin. Finished Dextrins are very fine powder varying in color from pure white to off white. Dextrins are prepared by roasting starch in the presence of acid, which chemically changes the character and properties of starch.
