ACCELERATED SOLVENT EXTRACTION APPLIED TO TOMATO POLYPHENOLS ASSESSMENT
Nowadays consumers and industrial stakeholders are becoming aware of the importance of food quality both for the nutritional and compositional viewpoint. Tomato products (fresh tomato, juices, purees, pulps, concentrates and sauces) naturally contain numerous bioactive molecules such as carotenoids, ascorbic acid and phenolic compounds, especially flavonoids. In particular phenolic compounds have been recently the subject of many research studies because of their probable role in the prevention of various diseases associated with oxidative stress. Hence the aim of this work was to develop and optimize an automated extraction and quantification method for tomato phenolic measurement through an ASE (Accelerated Solvent Extraction) technique coupled to HPLC analysis. This new method allows to increase extraction recovery of rutin and naringenin, the most representative flavonoids in tomato and to completely automated the analytical procedures, saving time and solvent.
