Abstract

The invention discloses a method for detecting low-quality starch-doped potato starch fast. The method comprises the following steps: qualitatively distinguishing whether sweet potato starch, tapioca, corn starch and wheat starch are doped in potato starch or not through electronic microscope imaging and starch grain shape and grain size analysis; quantitatively analyzing the doping quantity of low-quality starch doped in the potato starch through infrared spectroscopic analysis. Test results show that the method for qualitatively and quantitatively detecting the low-quality starch doped potato starch is simple, fast and high in forecasting capability and stability, thereby having an excellent market application prospect.

Description

technical field

[0001] The invention relates to a method for detecting potato starch adulteration, in particular to a qualitative and quantitative detection method for potato starch adulterated sweet potato starch, cassava starch, wheat starch and corn starch. Background technique

[0002] Negative events in the food field have caused people from all walks of life at home and abroad to worry about my country's food safety. It is imminent to rectify the food industry, improve product quality, and restore consumer confidence. At present, my country is still in a period of high incidence of food safety risks and prominent contradictions. Food safety issues have become a deep-seated, cross-regional, and cross-industry important social issue. While the country is gradually improving its legislation, it still needs to carry out diversified and all-round supervision and management.

[0003] Food counterfeiting or adulteration has become another important factor that threatens food...
