Measurements to the fresh green pepper were done on
both sides of the pepper tissue, that is to say, from the skin
(external) and the flesh (internal) sides.
Texture profile analysis (TPA) to all the samples was performed
using a Texture Analyser (model TA.XT.Plus). The
texture profile analysis was carried out by two compression
cycles between parallel plates performed on cylindrical
samples (diameter 10 mm, height 3 mm) using a flat 75 mm
diameter plunger, with a 5 s of time between cycles. The
parameters that have been used were the following: 5 kg force
load cell and 0.5 mm s−1 test speed.
The textural properties: hardness, springiness, cohesiveness,
and chewiness were calculated after Eqs. (1)–(4) (see
