Soaps test in Oils and Fats
Soaps are salts of fatty acids obtained from a reaction that occurs between free fatty acids and sodium carbonate. Thanks to their water solubility and insolubility in oil, they can be separated from fat through specific procedures. Food industries use this technique to lower fat acidity and to enhance its organoleptic characteristics. For such industries, it is important to carry out a chemical analysis for determining the concentration of soaps in oil and fat.
CDR FoodLab® method simplifies and speeds up the official procedure C8 NGD-1976 for testing the soaps in fats and, thanks to micro quantities used, allows to extend the analysis to samples of fat extraction is difficult.
At specific pH values soaps mixed with bromphenol, generate a specific blue colour. Its intensity, measured at 604 nm, is directly proportional to the concentration of soaps in the sample. CDR innovative method simplifies and accelerates the standard procedure to testing soaps in oils and fats, because it enables the test to be carried with micro-quantities and to be applied to fats that are difficult to extract.
The method CDR FoodLab® for analyze the concentration of soaps in oils and fats shows a good correlation with the reference method NGD C8-1976
