2.4. Texture analysis
Firmness of the samples was analyzed using a texture analyzer
(TA.XT plus, Stable Micro Systems Ltd., Godalming, UK). The
compression test was carried out with a cylindrical probe of 36mm
diameter. The probewas set to compress a sample to a depth of 50%
height from the contact point; pre-test, test and post-test speeds
were 1.5, 0.5 and 10 mm/s, respectively. Firmness was determined
by the maximum peak force.
