Little is known about the oral processing behavior of gluten-free (GF) products. This study investigated the oral processing behavior of one commercial GF bread and one gluten-containing (GC) equivalent with and without spreads. Oral processing parameters were determined through video recording and the predominant texture attributes were accessed using a check-all-that-apply test. The GF bread was perceived crumbly, dry and sandy and had a longer eating duration than the GC bread, which was perceived soft, spongy, pasty and sticky. Results suggest that the structure of the GF bread was easily fragmented during mastication and a longer period in the mouth was required to prepare a cohesive bolus for swallowing. The addition of spreads increased softness perception but did not affect chewing behavior. Oral processing behavior of GF products should be further investigated to understand how eating rate, satiation responses and food intake can be modulated in GF products.

Abstract

Little is known about the oral processing behavior of gluten-free (GF) products. This study investigated the oral processing behavior of one commercial GF bread and one gluten-containing (GC) equivalent with and without spreads. Oral processing parameters were determined through video recording and the predominant texture attributes were accessed using a check-all-that-apply test. The GF bread was perceived crumbly, dry and sandy and had a longer eating duration than the GC bread, which was perceived soft, spongy, pasty and sticky. Results suggest that the structure of the GF bread was easily fragmented during mastication and a longer period in the mouth was required to prepare a cohesive bolus for swallowing. The addition of spreads increased softness perception but did not affect chewing behavior. Oral processing behavior of GF products should be further investigated to understand how eating rate, satiation responses and food intake can be modulated in GF products.
