Abstract

The invention discloses a detection method for potassium sorbate in wheat flour and relates to the technical field of quality control and quality safety of agricultural products/foods, aiming at solving the problems in the prior art that a detection process is complicated and difficult and the consumed time is long. The method comprises the following steps: obtaining a potassium sorbate and wheat flour mixture sample; determining an absorption spectrum of the sample by adopting a terahertz time-domain spectroscopy system; according to the absorption spectrum, determining an absorption coefficient of a characteristic absorption peak of the sample; according to the absorption coefficient of the characteristic absorption peak of the sample, determining a concentration value of the potassium sorbate in the sample through a relation between the absorption coefficient of the characteristic absorption peak of the sample and the concentration of the potassium sorbate in the sample. Compared with the prior art, the method has the characteristics of simplicity in detection and short detection time; the detection method is a safe, efficient and high-precision nondestructive testing method.

Description

technical field [0001] The invention relates to the technical field of agricultural product / food quality control and quality safety, and more specifically relates to a method for detecting potassium sorbate in wheat flour. Background technique [0002] Since wheat is one of the main food crops in my country, as a food additive recognized as safe and highly effective in antisepsis, sorbic acid and potassium salt are more and more widely used in the food / agricultural product industry. However, if the content of potassium sorbate exceeds the standard, it will cause excessive content in the human body, which will adversely affect the health of the kidney and liver to a certain extent. [0003] At present, the commonly used detection methods of potassium sorbate in the agricultural product / food industry mainly include: thin-layer chromatography, high-performance capillary electrophoresis, high-efficiency phase chromatography, etc. However, these technologies have the problems of...
