Stable High Lipid Ketogenic Formula via Casein Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ketogenic diet formulations for tube feeding are unstable, prone to phase separation, and have limited viscosity, making them unsuitable for long-term storage and administration, especially in small tubes, which can lead to clogging and incomplete nutrition.
Innovation Solution
A sterile liquid composition with a high lipid content (>80% of total calories) stabilized by a protein-fibre blend of casein, resistant starch, soy fibre, and inulin, which prevents precipitation and phase separation, maintaining stability for over 6 months and suitable for tube feeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high lipid content (>80% of total calories) is used in ketogenic diet formulation, then therapeutic effectiveness for refractory epilepsy is improved, but phase separation and instability occur
Solution Approach 1:
The patent uses casein as an intermediary substance to stabilize the high-lipid emulsion. Casein forms a protective film around lipid droplets, preventing phase separation while maintaining the required >80% lipid content for therapeutic effectiveness in refractory epilepsy treatment.
Solution Approach 2:
The invention creates a composite emulsion system combining lipid, casein, and dietary fibre. This composite structure leverages the emulsifying properties of casein and the stabilizing effects of fibre to maintain homogeneity in high-lipid formulations, resolving the contradiction between high lipid content and stability.
2Stability of the object's composition
If thickeners are added to prevent sedimentation of insoluble ingredients, then stability is improved, but viscosity increases beyond acceptable range for tube feeding
Solution Approach 1:
The patent replaces conventional thickeners with a natural stabilizing system using casein and dietary fibre. This approach achieves sedimentation prevention without the excessive viscosity increase associated with traditional thickening agents, maintaining ease of administration through small-bore tubes.
3Stability of the object's composition
If powder compositions are used instead of ready-to-use liquid, then storage stability is improved, but preparation complexity and potential for errors increase
Solution Approach 1:
The patent applies preliminary stabilization actions during manufacturing by incorporating casein and dietary fibre into the liquid formulation. This pre-stabilization allows the product to maintain stability in ready-to-use liquid form without requiring complex preparation procedures, eliminating both storage and preparation complexity issues.
4Reliability
If high lipid content is used to achieve ketogenic effect, then therapeutic benefit is improved, but risk of tube clogging increases
Solution Approach 1:
Casein acts as an intermediary that prevents lipid aggregation and sediment formation. The casein-coated lipid emulsion maintains fluidity and homogeneity, preventing tube clogging while preserving the high lipid content necessary for ketogenic therapeutic benefit.
Solution Approach 2:
The composite emulsion system combining lipid, casein, and dietary fibre creates a stable homogeneous mixture that resists phase separation and sedimentation. This composite structure prevents tube clogging while maintaining >80% lipid content for effective ketogenic therapy.
