Cromatografia líquida de alta eficiência como método de análise de bebidas não alcoólicas de origem vegetal

Abstract

In the context of the sciences that study food, bromatological analysis is of fundamental importance, as it allows the evaluation of the various segments of food quality and safety, ranging from the chemical composition of food, its chemical, physical and toxicological properties to adulteration, contamination and frauds. Since foods and beverages have complex organic hues and there is a need for increasingly reliable results, the development of more precise instrumental methods becomes imperative. Among the current instrumental analysis techniques, Chromatography, especially High Performance Liquid Chromatography, stands out for being a method that allows the separation of compounds from the sample of interest and their qualitative and quantitative evaluation, in addition to allowing the use of other analytical methods together. Given the various possibilities of analysis through High Performance Liquid Chromatography, this technique is effective for the evaluation of samples as complex as food nuances, being possible to evaluate different compounds simultaneously, which allows a panoramic analysis of the products, being possible conclude that the technique presents a very considerable cost-benefit ratio.
