Abstract: This study was conducted to identify the starch properties of Pueraria lobate. Ten plants(Pueraria lobate,potato,rice,glutinous rice,white lotus,sorghum,red beans waist,oats and millet corn) were used to compare the differences in starch properties. The results showed that there are significant difference in morphological shapes of starch granules among the plants. The starch granules of potato,white lotus,red beans waist are larger than those of Pueraria lobate,cassava,rice,glutinous rice,oats and millet corn. Red beans waist has the highest amylose content among all the plants and glutinous rice has the lowest. The Pueraria lobate amylose content is only 16.04%. The absorbance of starch increases when temperature rises. In the range from 30 to 60℃,no significant differences in the absorbance are found among the plants.When temperature gose up to 85 ℃,sorghum shows the lowest absorbance and the glutinous rice has the highest. Absorbance of Pueraria lobate starch is 0.452 at 85℃,and its gelatinization temperature is between 66 and 85 ℃.
Key words: Pueraria lobate, starch-rich plant, starch property
