The use of capillary electrophoresis (CE) as an analytical technique has become more widespread and popular in recent years and has established itself as a method of choice for many applications. The ability to analyze small ions and organic molecules has made it the mainstay in many industries such as the food and beverage, biotechnology, and pharmaceutical industries, many of which have incorporated CE into their research as well as their quality assurance (QA) and quality control (QC) departments.

Faster and finer approaches for the analysis of food proteins are necessary for the assurance of food quality and safety (106). Generally, the most recent applications of microchip electrophoresis for the analysis of proteins or peptide biomarkers in foods include the characterization of protein extracts (107), the detection of high-quality value products adulterated with products of inferior quality (108), and the evaluation of the quality due to food storage or different technological process (109). 

Internal markers or standard proteins have most often been used by researchers to assure themselves that separations by electrophoresis are consistent and reproducible (21). In addition, charge markers In Isoelectric focusing are also used, although standard preparations of these materials are less reliable, especially under denaturing conditions. Other Internal standards that are often reported are materials for assuring radlolabel activity, enzyme activity, or other materials to monitor repeatability of measurements. In all cases, the stability of the standard material Is the key to long-term quality control. Large, batches of standards that are reproducible from lot to lot would also be useful.
