Food structure: Roles of mechanical properties and oral processing in determining sensory texture of soft materials

Abstract

There is a desire to alter food composition to make foods healthier and at the same time not diminish sensory quality. This requires an understanding of key elements of food structure associated with texture perception. Texture, in part, is perceived during oral processing of food. Knowledge of structure–oral processing–texture interrelations could be utilized to develop or prevent specified textural attributes. Overall, the investigation of structure–oral processing–texture interrelations is just starting as a research focus. Factors including non-universal and inconsistent sensory terminology, omission of consideration for structural changes incurred by oral processes, and the lack of cross-disciplinary investigations hamper progress in this field. Consideration of these factors in future investigations on sensory texture will increase the applicability of their findings and bring us closer to understanding the contribution of food structure to sensory texture.
