Abstract
Publisher Summary Food and herbs are main natural sources of antioxidants. In this connection, antioxidant activity (AOA) of these products is essential for planning right diet as well as for sound therapy. Screen-printed platinum sensor and potentiometric method of measuring AOA of food and herbal extracts are presented in this chapter. The study of extract AOA allows concluding that AOA of water–ethanol extracts is higher than AOA of water extracts. It results from the fact that polyphenols, main antioxidants in plants, are better extracted by ethanol than by water. To sum up, potentiometric determination of AOA with the use of screen-printed platinum sensor provides the possibility to analyze foodstuff and herbal extracts. The method is easy to use, express and reliable. Information on AOA of foodstuff can be applied for quality monitoring of the product and raw materials. It can be realized in onsite and on-line formats for production processes control.
