Classification of Texture-Modified Korean Soups with a Thickener under IDDSI Criteria / 대한연하장애학회지

Objective@#This study aimed to develop texture-modified soups and classify them based on the International Dysphagia Diet Standardization (IDDSI) and National Dysphagia Diet (NDD) criteria. @*Methods@#Ten soups were selected, and a xanthan gum-based thickener was added to adjust their viscosity. Flow tests with a 10 ml syringe and viscosity measurements using a rheometer were carried out according to the IDDSI and NDD criteria. @*Results@#The addition of 1 g of thickener to the selected commercial soups resulted in different viscosity levels depending on the soup type. Under the IDDSI framework, seven soups (R SMG, BMG, KHG, SLT, B SUG, BGG, DGT) were categorized as level 1, two soups (B MYG, ADG) as level 2, and one soup (R DJJ) as level 3. As per NDD guidelines, seven soups (R SMG, BMG, KHG, SLT, B SUG, BGG, DGT) were classified as Nectar-like and three soups (R DJJ, B MYG, ADG) as Honey-like. However, the addition of 2 g of thickener decreased the fluidity of the soups, with two soups (R SMG, SLT) being classified as level 2 and eight soups (R BMG, DJJ, KHG, B SUG, MYG, ADG, BGG, DGT) as level 3 under the IDDSI criteria. Meanwhile, all soups were classified as Honey-like under the NDD criteria. @*Conclusion@#The viscosity was different due to the varying compositions of guk/tang/jjigae, the concentration of the thickener, and time. Swallowing standardsands and other guidelines applicable specifically to Korean-food for dysphagia patients need to be developed in a further study.

Designed Meal Development and Sensory Evaluation for Dysphagia Patients / 대한연하장애학회지

Objective@#Thickening agents used in dysphagia diets to adjust the viscosity of foods adversely affect the inherent food flavors and colors. Chopped and ground foods have unfamiliar flavors, colors and textures, causing a loss of appetite. Therefore, this study aimed to develop a savory and easy-to-make dysphagia diet without changing the appearance and taste of foods, and evaluate the suitability of the newly developed diet for patients with dysphagia. @*Methods@#Twenty participants aged 55-85 years (8 patients with dysphagia and 12 healthy elderly) were recruited.The diet consisted of fried rice, hamburger steak, and soybean paste soup, where the solid foods were categorized as International Dysphagia Diet Standardisation Initiative (IDDSI) Level 5 (Minced and Moist), and the liquid foods were categorized as IDDSI Level 2 (Mildly Thick). To develop the dysphagia diet, textural modifications to the ingredients and viscosity adjustments were applied. A sensory evaluation was conducted by the panel to measure the extent of chewing, swallowing, adhesiveness, choking, and overall flavor and preference. @*Results@#No significant differences in textural properties, such as chewing, swallowing, adhesiveness and choking, were observed between the control and patient groups, but the flavor and preferences in the patient group were statistically significant. @*Conclusion@#The modified and newly designed dysphagia foods positively impacted easy swallowing for patients with dysphagia. Therefore, customized dysphagia foods should be considered in terms of flavor-enhancement to provide tailored diets for patients with dysphagia.
