Solution Overview

Problem

Butyric acid and tributyrin have negative sensory qualities such as vomit-like, fecal, and cheesy aroma attributes, making oral administration difficult, especially in pediatric populations, and medium chain triglycerides (MCT) cause gastrointestinal intolerance at high doses, limiting ketone production.

Innovation Solution

Development of triglycerides composed of a mixture of butyrate and medium chain fatty acids (MCFAs) with improved odor and taste, providing a dietary source of butyrate and ketones without additional mineral salts, synthesized through esterification or interesterification processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If butyric acid or tributyrin is used as a dietary source, then butyrate delivery is achieved, but negative sensory qualities (vomit-like, fecal, cheesy aroma) make oral administration difficult

Engineering Contradiction:
Improvebutyrate deliveryVSAvoidoral administration
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent uses medium chain fatty acids (MCFAs) as intermediary components to create mixed triglycerides that mask the unpleasant sensory qualities of butyric acid while maintaining butyrate delivery functionality. The MCFA portion acts as a mediator that improves organoleptic properties without compromising the therapeutic effect.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention creates composite triglyceride molecules combining butyrate chains with medium chain fatty acid chains. This composite structure integrates the beneficial butyrate delivery function with the improved sensory properties of MCFAs, resolving the contradiction between efficacy and acceptability.

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If medium chain triglycerides (MCT) are used at high doses to produce ketones, then ketone production increases, but gastrointestinal intolerance occurs

Engineering Contradiction:
Improveketone productionVSAvoidgastrointestinal intolerance
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters of the triglyceride by incorporating butyrate chains alongside MCFA chains. This parameter modification allows the formulation to produce ketones effectively while reducing the gastrointestinal side effects associated with high-dose pure MCT consumption.

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If pure butyrate formulations are used, then butyrate supplementation is achieved, but additional mineral salts are introduced

Engineering Contradiction:
Improvebutyrate supplementationVSAvoidadditional mineral salts
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The invention applies local quality by creating triglyceride molecules where only specific portions (the fatty acid chains) provide the desired butyrate supplementation, while the glycerol backbone and MCFA chains do not introduce unwanted mineral salts. This localized functionality achieves supplementation without contamination.

Inventive Principle:
Principle #3Local quality
