Abstract

Official abstract text for this publication.

Nutritional products having improved cohesiveness of food boluses and methods of making and using same are provided. The nutritional products may include nutritional compositions and high molecular weight, water-soluble polymers such that the nutritional products have extensional viscosities that provide improved cohesiveness to the nutritional products and Trouton ratios of at least 6. Methods of administering such nutritional products to patients having impaired swallowing ability and/or dysphagia are also provided.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of replacing saliva in an individual in need thereof, the method comprising: administering an effective amount of a liquid nutritional product to the individual, the liquid nutritional product comprising a nutritional composition and a food-grade polymer, wherein the food grade polymer is selected from the group consisting of okra gum, konjac mannan, tara gum, fenugreek gum, tamarind gum, cassia gum, cactus mucilage, mallow mucilage, flax seed mucilage, marshmallow mucilage, ribwort mucilage, mullein mucilage, cetraria mucilage, and combinations thereof, the liquid nutritional product comprises an amount of the food-grade polymer such that the liquid nutritional product has an increased cohesiveness relative to the nutritional composition and has a Trouton ratio of 6 to 15. 2. The method of claim 1 , wherein the liquid nutritional product has an extensional viscosity greater than 100 mPa s. 3. The method of claim 1 , wherein the food grade polymer is okra gum and/or cactus mucilage. 4. The method of claim 1 , wherein the food grade polymer is selected from the group consisting of mallow mucilage, ribwort mucilage, mullein mucilage, and mixtures thereof.
