Title: Study on Adulterate Check and Measure in Sweet Potato Starch
Abstract: To solve the malpractice unpurity of the starch in noodle making caused by maize starch mixed with sweet potato starch and the higher breaking rate of starch noodle, and according to the principle that the two have different structures and different colours when they meet iodine preparation, we made up respectively starch test solutions of definite concentration with pure starch of sweet potato and maize and mixed starch of various contents of maize starch. From the different colours shown when compound preparation of iodine was put in them, it could be defined if maize starch was mixed with sweet potato starch or not. Photoelectric spectrophotometer was used to determine the light-absorbent rate of the test solutions of mixed and the content of maize starch in mixed starch was calculated by data regression equation.
