Pea and Soy Proteins for Reduced Caseinate Gastric Coagulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Protein coagulation in the upper gastrointestinal tract, particularly in the stomach, leads to complications such as reflux, gastrointestinal discomfort, and aspiration pneumonia, especially in nutritional compositions containing casein and/or caseinate, delaying gastric emptying and causing issues like intestinal discomfort, reflux, aspiration pneumonia, high gastric residual volume, vomiting, nausea, bloating, and delayed gastric emptying.
Innovation Solution
Incorporating anti-coagulating proteins like pea and soy proteins into nutritional compositions to reduce protein coagulation, achieving a synergistic effect that minimizes coagulation by including a non-coagulating protein, such as pea or soy protein, in combination with caseinate, thereby reducing the formation of large protein particles in the stomach.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nutritional compositions containing casein and/or caseinate are administered, then protein coagulation occurs in the stomach, but this leads to upper gastrointestinal complications like reflux, gastrointestinal discomfort, and aspiration pneumonia
Solution Approach 1:
The patent introduces vegetable proteins (pea, soy, rice, corn, potato) as intermediary substances that mediate between the coagulating casein proteins and the gastric environment. These intermediary proteins prevent direct coagulation of casein by interfering with the acid-induced aggregation process, thereby reducing gastrointestinal complications while maintaining the nutritional benefits of casein-containing compositions
Solution Approach 2:
The patent creates composite protein systems by combining casein/caseinate with vegetable proteins in specific ratios. This composite approach leverages the complementary properties of different protein sources: casein provides high nutritional value while vegetable proteins provide anti-coagulating properties. The composite material exhibits reduced coagulation behavior compared to pure casein, resolving the contradiction between nutritional efficacy and digestive comfort
2Quantity of substance
If casein and/or caseinate are used in nutritional compositions, then high protein content is achieved, but coagulation in the stomach delays gastric emptying and causes high gastric residual volume
Solution Approach 1:
Vegetable proteins act as mediators that prevent excessive coagulation of casein in the gastric environment. By interfering with the acid-induced coagulation process, they maintain protein solubility and prevent the formation of large coagulated masses that would delay gastric emptying, thus reducing gastric residual volume while preserving high protein content
Solution Approach 2:
The patent modifies the coagulation parameters of the protein mixture by combining casein with vegetable proteins having different isoelectric points and coagulation behaviors. This parameter change approach alters the overall coagulation characteristics of the nutritional composition, making it less prone to forming large coagulated particles that would delay gastric emptying
3Stability of the object's composition
If casein/caseinate coagulates in the stomach, then protein precipitation forms, but this results in vomiting, nausea, and bloating
Solution Approach 1:
Vegetable proteins serve as protective intermediaries that prevent excessive coagulation and precipitation of casein in the gastric environment. They maintain protein solubility through steric hindrance and electrostatic repulsion, preventing the formation of large precipitates that would cause vomiting, nausea, and bloating, while still allowing controlled protein digestion
