Разработка и валидация количественного определения суммы свободных органических кислот в плодах брусники

Abstract

The qualifying work is devoted to the development and validation of the quantitative determination of the amount of free organic acids. The conformity of the raw materials of lingonberry fruits with the normative document has been established. Identification and quantitative determination of organic acids in lingonberry fruits was carried out. It has been established that the results of determining the content of organic acids by the potentiometric and conductometric methods are comparable to each other. A titrimetric method for determining the amount of free organic acids in lingonberries has been developed and validated.
