Abstract: In this paper,the properties and the optimum conditions for the proparation of hydroxypropylated- phosphate monoester corn starch were studied. The results showed: the hydroxypropylated-phosphate monoester compound modified corn starch gained the merits of the single modified starches and overcame at the same time their shortcomings and thence forth the degree of transparency, the freeze-thaw stability, the effects of cane sugar and foam-holding capacity were improved.

Key words: Modified starch , Phosphate Monoester , Hydroxypropylation , Compond modification
