Abstract: The effect of different conditions on the formation of digestible oxidation starch was studied in this paper. Experimentsproved that the effect of NaOCl was the most significant in the factors which influenced on content of the carboxyl anddigestibility when potato starch was used as material and NaOCl as oxidant. According to the orthogonal array experiment, theoptimum technics to produce the oxidation starch of good digestibility has been confirmed. It was maintained at a dosage ofNaClO of 3%, a time of 2 hours, a temperature of 30℃and a pH of 10.It was found that the correlation between content of thecarboxyl and digestibility was positive in some extent by reseach.

Key words: oxidation starch, content of the carboxyl, digestibility, viscosity
