The effects of substitution degree on paste viscosity,clarity,freeze-thaw stability,retrogradation,gelatinization difficult or easy degree,salt tolerance,sucrose tolerance and anti-mycotic characteristics of colocasia esculenta schott starch phosphate ester were studied.

Highly purified amylopectin and amylose from taro starch could be obtained by re-crystallization.

Amylograms of the taro starch were studied with Micro Visco-Amylo-Graph instrument under different conditions, such as mass fraction, pH, addition amounts of sucrose, salt, alum and borax.

?The physical properties and characters of taro starch extorted by a special technique are analyzed and the effects used in cosmeties are also presented in the essay.

In this paper, a recovered moyu starch for industry has been treated and made into a new type adhesive, The influence of various reaction condition and composition on the properties of the stareh adhesive was researched.

In this paper, we have reported a super-absorbent polymer, which was prepared from graft copolymerization of acrylamide onto potato starch used ammonium eerie nitrate and N ,N' -methy-lene-bis-acrylamide as an initiator and cross-linking agent respectively, then was hydrolyzed.

[Method] Potato starch and acrylate were used as materials to prepare super absorbent resin by grafting.
