3.1. Impact of HP and HPHT processing on dry matter content
The initial dry weight (DW) of the raw vegetables used in the study is shown in Table 2. The DW values obtained are within the ranges reported in the literature (Granado et al., 1992 and Guil-Guerrero et al., 2006).No significant differences were observed in dry matter content between different HP and HPHT treatments (625 MPa; 5 min; 20, 70 and 117 °C) and raw controls for any vegetable tested (data not shown). Therefore, the following results concerning the impact on chlorophylls and carotenoids were expressed on a fresh weight basis.
