Abstract: A method of measuring the length of thread of starch paste with texture analyzer was introduced . According to the mechanism on the formation and breakage of thread of starch paste , as the probe moves up with the mode of tension from the starch paste, the texture analyzer induces a tensile curve on the relation of Force and Time/Distance, hence the length of thread of starch paste can be figured out. This method has good repeatability and accuracy, also produces the information of the rupture and pull velocity of the thread and the adhesive property of starch paste, so better specified properties of starch and modified starch can be understood quite differenty from the former.
