dc.description.abstract There is limited knowledge on provisions used to ensure swallowing safety, nutritional adequacy and sensory acceptability of pureed foods in long-term care homes (LTCHs). The overall aim for this research was to expand knowledge of pureed food production in LTCHs, to study the impact of varying ingredients and preparation on sensory and nutrition and to model perceived oral textures in pureed food. Qualitative interviews with dietary staff (n=53) in 25 LTCHs showed a variety of challenges and practices in production, affecting overall quality. Pureed turkey varying in added liquid, meat muscle and seasoning method and pureed carrots varying in thickener type were evaluated by a descriptive sensory panel (n=10). Results indicate that small formulation changes can have a significant impact on the nutrition and sensory properties of pureed food. Instrumental tests using a viscometer, line-spread test and texture analyzer showed different strengths in predicting variation in orally-perceived textures. en_US
