As a commonly used food additive, tert-butyl catechol (TBHQ) is widely used in food processing, and its main role is to resist oxidation and extend shelf life. With the increasing attention to food safety, the detection and analysis of TBHQ has become particularly important. How to detect the content of TBHQ? Below we will discuss several common TBHQ detection methods and analysis techniques in depth.

Traditional chromatography is a common method for TBHQ detection. Chromatography determines the content of TBHQ in a sample by separating it into individual components and analyzing these components using a chromatographic column. This method has the characteristics of high sensitivity and good accuracy, and is widely used in the field of food safety. In addition, high performance liquid chromatography (HPLC) is also a commonly used TBHQ detection method. Its principle is to separate the sample in the column under fixed conditions, and then determine the content of TBHQ according to the residence time of different components on the column, which has the characteristics of high efficiency and accuracy.

In addition to traditional chromatography, spectroscopy has also been widely used in the detection of TBHQ in recent years. For example, infrared spectroscopy (IR) and ultraviolet-visible spectroscopy (UV-Vis), etc. These methods determine the content of TBHQ molecules by detecting their interaction with light of a specific wavelength. Compared with the traditional chromatography, spectroscopy has the characteristics of simple operation and fast speed, especially for the rapid detection of large quantities of samples.

With the development of biotechnology, biosensors have become an emerging technology for TBHQ detection. Biosensor is a technology that uses the specificity and sensitivity of biological systems to detect target substances, including enzyme sensors, antibody sensors and so on. Highly sensitive and highly selective detection of TBHQ can be achieved by combining appropriate biological elements with the sensor. This method can not only detect the content of TBHQ quickly and accurately, but also has the advantages of low cost and easy to realize automation, which is of great significance for the food processing industry.

There are various detection methods and analysis techniques for TBHQ, and each method has its unique advantages and scope of application. Choosing the appropriate detection method can not only ensure food safety, but also provide more technical support and guarantee for the food processing industry. In the future development, I believe that with the continuous progress and improvement of technology, TBHQ detection methods and analysis technology will be more diversified and precise, and escort people's health and safety.
