METHODS OF DETERMINING TOTAL ACIDITY" The object of research is canned food and fish and seafood preserves. The purpose of the work was to develop a method for determining titrated acidity: visual (titrimetric) and potentiometric methods in canned fish and seafood preserves. To solve the set goal, the following tasks must be solved: - to develop a visual (titrimetric) method for determining acidity in fish and seafood preserves; - to develop a potentiometric method for determining acidity in fish and seafood preserves. Research methods: visual (titrimetric) and potentiometric. The research was conducted on the basis of the testing laboratory of the SE "KYIVOBLSSTANDARTMETROLOGIA". The developed technique applies to canned goods and fish and seafood preserves. The essence of the visual (titrimetric) method is the titration of water-soluble acids in the product with sodium or potassium hydroxide solution in the presence of the phenolphthalein indicator. The potentiometric method is based on the titration of water-soluble acids in the product with sodium or potassium hydroxide solution in the presence of two electrodes (glass and reference electrode). The use of titrated acidity allows you to confirm the compliance of the quality of food products with the requirements of regulatory documents, as well as compliance with the product manufacturing recipe; determine product quality.
