Abstract
The incidence and prevalence of dysphagia worldwide are increasing yearly requiring a change in food texture to avoid malnutrition, dehydration, or sever complications. Riceberry porridges fortified with protein hydrolysate (1.5%), bio-calcium (589 mg), and thickened with xanthan gum (XG) of varying concentrations (0%, 0.255, 0.50%, 0.75%, 1.0%, and 2.0%) showed suitability for use in enriching diets of these patients. Porridges were examined using specified tests from the International Dysphagia Diet Standardization Initiative (IDDSI) and National Dysphagia Diet (NDD), and coupled with rheological, textural analyses, in vitro swallowing simulator and sensory analysis performed by a trained panel. Porridges with 0%–0.25% and 0.50%–2.0% XG were classified as IDDSI level 3 and 4, respectively, and apparent viscosities of porridges showed samples with XG displayed shear thinning behavior beneficial for patients with dysphagia. Increasing XG concentrations increased the consistency coefficient and decreased the flow behavior index (p < .05) with positive correlation of XG concentration with textural properties including firmness, consistency, cohesiveness, adhesiveness, and stickiness values. The relationship between instrumental measurements, in vitro and in vivo swallowing behavior showed high correlations with regards to XG concentration (r = .995). The findings indicate Riceberry porridges containing XG have significantly improved textural properties over those without XG for patients with dysphagia.
期刊介绍：
The Journal of Texture Studies is a fully peer-reviewed international journal specialized in the physics, physiology, and psychology of food oral processing, with an emphasis on the food texture and structure, sensory perception and mouth-feel, food oral behaviour, food liking and preference. The journal was first published in 1969 and has been the primary source for disseminating advances in knowledge on all of the sciences that relate to food texture. In recent years, Journal of Texture Studies has expanded its coverage to a much broader range of texture research and continues to publish high quality original and innovative experimental-based (including numerical analysis and simulation) research concerned with all aspects of eating and food preference.
Journal of Texture Studies welcomes research articles, research notes, reviews, discussion papers, and communications from contributors of all relevant disciplines. Some key coverage areas/topics include (but not limited to):
• Physical, mechanical, and micro-structural principles of food texture
• Oral physiology
• Psychology and brain responses of eating and food sensory
• Food texture design and modification for specific consumers
• In vitro and in vivo studies of eating and swallowing
• Novel technologies and methodologies for the assessment of sensory properties
• Simulation and numerical analysis of eating and swallowing
