Texture was measured using a Universal Testing Machine, Servosis ME-405/1+PCD 1065 W (Madrid, Spain) at a compression rate
of 30 mm/min, with a 8 mm diameter cylinder. The force was recorded for 1 cm penetration. Pimento puree with a 1% fiber concentration was transferred to a glass pot (10 cm diameter) and
after 1 h (room temperature) texture was measured (texture before heat treatment). The samples were sterilized and texture again
measured. The following parameters were determined: Hardness
(N) maximum force required to compress the sample, Springiness
(mm) ability of sample to recover to its original shape after the
deforming force was removed, Cohesiveness extent to which sample could be deformed prior to rupture (A2/A1), A1 being the total
energy required for the first compression and A2 the total energy
required for the second compression, Adhesiveness representing
the work, caused from a tensile force, needed to pull food apart
and separate it from the compression cylinder, Stringiness distance
food extends before it breaks away from the compression plates.
