All samples were tempered at room temperature. (19 ± 2 ° C) for 10 min. Texture analysis was con ducted using a TA.XT2 Texture Analyser (Stable Micro Systems, Reading, UK), fitted with a 6-mm diameter stainless steel probe, set up to record the force used to penetrate the sample to a depth of 25 mm at a speed of 1 mm / s. Hardness was measured as the peak compression force (N) during the penetration of the sample, and stickiness as the negative peak force (N) during withdrawal.
