Texture of the samples was determined 2 days after production, using a Texture Expert TA.XT2 (Texture Technologies, Scarsdale, NY, USA) as described by Herrero et al. . Six cores (diameter = 2 cm; height = 1.5 cm) were cut from each sample and were axially compressed by a two-cycle compression test to 60% of their original height using an aluminum 50 mm cylindrical probe. The measurements were performed at room temperature. Force-time deformation curves were recorded with a 25 kg load cell at a crosshead speed of 1 mm s -1 . Attributes were calculated as follows: hardness (N), peak force required for first compression; adhesiveness (N) is the negative force area after first compression; springiness (dimensionless), considered as the distance the sample recovers after first compression as related to the original height; cohesiveness (dimensionless), as the ratio of positive force peak area of the second and the first compression; and chewiness (N), the product of hardness by cohesiveness and springiness. TPA parameters (Table ) are given as the average of six replicated measurements pr formulation (tubes 1-6).
