Unlabelled: Texture-modified diets (TMDs) are a primary compensatory treatment for hospitalized older patients with swallowing and mastication disorders. Nevertheless, the lack of a protocol for evaluating their objective textural properties hampers their industrialization and optimal patient care.
Objectives: This study aimed (a) to evaluate the textural properties (maximum force, cohesiveness, and adhesiveness) and biomechanics of food oral processing (mastication cycles, time, and frequency) of ten fork-mashable dishes (Texture E BDA/IDDSI level 6), (b) to explore the impact of oral processing on texture, and (c) to measure the properties of the ready-to-swallow bolus (RSB) in healthy adults.
Article Synopsis
- Texture-modified diets are essential for older patients with swallowing disorders, but lack standardization in assessing their textural properties, raising safety concerns.
- This study evaluated the rheological and textural characteristics of ten thick purees to understand oral processing effects and measure the ready-to-swallow bolus properties in healthy adults.
- Results showed significant variability in viscosity, maximum force, cohesiveness, and adhesiveness across purees, highlighting the importance of standardized quality control protocols to ensure optimal diets for patients with dysphagia.
Besides shear viscosity, other texture parameters (adhesiveness or cohesiveness) might be relevant for safe swallowing in people suffering from oropharyngeal dysphagia. Shear viscosity is assessed through protocols developed using a viscometer or a rheometer. In contrast, protocols and instruments (capillary break-up rheometer) to assess adhesiveness and cohesiveness are less common and much less developed.
