Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current nutritional compositions for individuals with dysphagia or other conditions like renal failure and chronic obstructive pulmonary disorders face challenges in maintaining consistent viscosity over time and temperature, leading to issues such as choking and aspiration, which existing thickeners fail to adequately address.
Innovation Solution
The development of stable thickener formulations using specific ranges of carrageenan and starch, combined with xanthan gum, that provide consistent viscosity across extended storage times and temperatures, suitable for various nutritional compositions, including those with different protein content, to create a stable and manageable texture for consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional thickeners are used in nutritional compositions, then the composition can be thickened to prevent choking and aspiration, but the viscosity becomes unstable over time and at different temperatures
Solution Approach 1:
The patent uses a composite thickening system combining multiple ingredients: carrageenan (0.01-0.05%), xanthan gum (0.01-0.05%), and modified food starch (0.5-5%). This composite approach creates synergistic effects where each component contributes different thickening and stabilizing properties, resulting in a formulation that maintains consistent viscosity across extended storage periods and temperature variations, directly resolving the instability issue of single-component thickeners
Solution Approach 2:
The patent systematically optimizes the concentration parameters of each thickening component within specific ranges to achieve desired viscosity characteristics. By adjusting the proportions of carrageenan, xanthan gum, and modified starch, the formulation maintains stable viscosity across different temperatures and storage times, transforming the unpredictable viscosity behavior into a controlled and reliable property
2Strength
If more starch is added to increase viscosity, then the thickening effect improves, but the formulation becomes less stable at refrigerated temperatures
Solution Approach 1:
Carrageenan and xanthan gum serve as intermediary substances that mediate between the starch granules and the liquid phase. These polysaccharides form a protective network around starch granules, preventing their excessive swelling and gelatinization at refrigeration temperatures. This intermediary mechanism allows the formulation to achieve strong thickening from starch while maintaining viscosity stability during refrigerated storage
Solution Approach 2:
The combination of carrageenan, xanthan gum, and modified starch creates a composite thickening system where each component plays a specific role: carrageenan provides initial thickening and stabilizes starch granules, xanthan gum enhances viscosity and prevents temperature-induced changes, and modified starch provides the bulk thickening effect. This composite approach enables strong thickening while preventing the instability that would occur with starch alone at refrigeration temperatures
3Ease of manufacture
If the thickener formulation is simplified to reduce manufacturing complexity, then production becomes easier, but the viscosity consistency and safety for dysphagia patients deteriorates
Solution Approach 1:
The patent defines specific parameter ranges for each ingredient (carrageenan: 0.01-0.05%, xanthan gum: 0.01-0.05%, modified starch: 0.5-5%) that optimize viscosity consistency while maintaining reasonable manufacturing simplicity. These standardized ranges allow for straightforward formulation preparation and quality control, balancing ease of manufacture with reliable viscosity performance for dysphagia patient safety

Function Achieved in This Case
These formulations maintain a stable viscosity similar to honey or nectar, reducing the risk of choking and aspiration, and can be used in a variety of nutritional compositions, ensuring effective management of dysphagia and other conditions by providing a consistent and safe eating experience.
Implementation Method 1
the addition of specific amounts of a thickener such as, for example, carrageenan, xanthan, and/or starch to a nutritional composition can provide the nutritional composition with a desired level of a viscosity
Implementation Method 2
By adding carrageenan, the starch level can be decreased. Also, the viscosity increase of nutritional compositions at refrigerated storage temperatures can be minimized when carrageenan and/or xanthan is added thereto
Implementation Method 3
The stable thickener formulations can also include specific amounts of xanthan gum and starch that provide a stable viscosity
