The method of capillary electrophoresis can be used to assess the quality, safety, falsification and identification of food and beverages. It is characterized by high accuracy (up to 97%) and efficiency. Using it, you can determine the content of various cations and anions, organic acids, carbohydrates, vitamins, amino acids, preservatives, antioxidants, flavonoids, synthetic dyes, which are of great importance for the technological control of production at the enterprise. The method of capillary electrophoresis allows you to determine the naturalness and quality of soft drinks and alcoholic drinks by detecting the presence or absence of organic acids in the sample, as well as analyzing their quantitative content and ratio, makes it possible to control enzymatic processes and correlate with the taste of the final product. In addition, this method can be used to assess the quality of water used as the main raw material for the production of beverages. It allows you to determine the content of pesticides and fungicides in the raw materials used for the production of food and beverages. The method is based on the electromigration of ions and electroosmosis and, as a consequence, the separation of a complex multicomponent system in a quartz capillary. The bottom line is that after applying voltage up to 30 kV to the prepared capillaries for analysis, the components of the mixture begin to move along the capillary at different speeds, thereby reaching the detection zone at different times. Thus, separation and subsequently detection of the test substances in a particular product, drink or raw material is achieved.

“…As a powerful separation and identification technique that can be used as a sample preprocessing in the analysis of ionic analytes, capillary electrophoresis (CE) [1] has been well developed and widely used in the fields of chemistry, biomedicine etc. [2]. Despite the CE has many advantages such as high throughput, smaller volumes, higher sensitivity and reduced cost [3], the detected CE signals are usually contaminated by random noise.…”

Since capillary electrophoresis (CE) signals are always contaminated by random noise, which has negative influence on the accuracy of detection and analysis, it is necessary to remove noise before further applications of the CE signals. In this study, a tight frame learned from the data itself is applied to the removal of noise for CE signals. To achieve an effective decomposition of the CE signal, a one-dimensional discrete tight frame tailored to the input signal is first constructed by introducing tight frame constraint into the popular dictionary learning model. Then, due to each subband containing different information of the noise, an adaptive threshold is computed to shrink the detail coefficients instead of using a global threshold. Finally, the denoised CE signal is reconstructed from the thresholded coefficients by using the inverse transform of the tight frame. To evaluate the denoising efficiency, the proposed method is applied to the simulated CE signals and real CE signals. Experimental results indicate that compared with other denoising methods, the proposed method obtains a better shape preservation of the peaks as well as a higher signal-to-noise ratio.
