Abstract(s)
The increasing worldwide consumption of cherry tomatoes (Solanum /ycopersicum L. varo cerasiforme) is explained by the great acceptability by the consumer, along with the ease in its trade and distribution. Despite being a fruit that
provides essential nutrients such as Iycopene, vitamin C, and phenolic acids, its consumption is closely related to its sensory characteristics such as taste, color, and appearance. Nevertheless, along the production chain, some by· products are
not used and are, therefore, discarded, generating large amounts of bio-residues. lhe use of such bio·residues, namely the aerial parts, as a source of valuable compounds that can find other applications in food industry as, for example, food
colorants, is a growing tendency [1-3). In this context, the following work aimed to explore the hydroethanolic extracts obtained from the aerial parts of cherry tomato in terms of chlorophylls. lwo extraction methodologies were used, namely
ultrasound assisted (USE) extraction for 15 minutes at 400 W and maceration assisted (EM) extraction for 120 minutes, both using 90% ethanol (v/v) as solvent shown by Figure 2. lhe chlorophyll pigments were identified and quantified through the
implementation of a chromatographic method, HPlC coupled to a diode array detector (DAD) and mass spectrometry (MS).
