Application of spectrophotometric analysis method for determining phosphates in complex food additives

Abstract

The study of the physico-chemical indicators of complex food additives used in the production of sausages is relevant. The scientific task — research on complex food additives (CFAs) to expand information about their properties, as well as to determine the possibility of adapting measurement methods for determining food phosphates in CFAs. Sixteen samples of CFAs in various commercial forms were studied using standardized and widely accepted research methods. Spectrophotometric studies conducted to determine the phosphate content in CFAs revealed that the used method could be applied to determine the mass fraction of total phosphorus in CFAs. Several samples showed that excessive phosphate content, which would result in increased total phosphorus content in the sausage products. When organizing incoming control at meat processing plants, it is advisable to monitor CFAs for the indicator of mass fraction of total phosphorus, as this indicator is regulated and affects the quality and safety of sausage products. Methods for controlling regulated quality and safety indicators in CFAs must be developed and implemented.
