Solution Overview

Problem

Existing soft capsule technologies face challenges in stabilizing probiotic supplements, particularly non-spore-forming probiotics, due to moisture sensitivity, which leads to a loss in viable colony-forming units and requires expensive and impractical manufacturing processes.

Innovation Solution

The development of stabilized softgel capsules that incorporate a core comprising a probiotic supplement, stabilizing components derived from chocolate, and an edible oil, encapsulated in a softgel shell. This formulation includes cocoa solids, cocoa butter, or cocoa nib paste as stabilizing components and uses edible oils with a melting point less than 35°C to maintain stability and bioavailability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If non-spore-forming probiotics are encapsulated in soft capsules, then patient compliance and consumer preference are improved, but moisture in the capsule shell rapidly causes loss in viable colony forming units

Engineering Contradiction:
Improvepatient complianceVSAvoidprobiotic viability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent extracts the probiotic supplement from direct contact with moisture in the capsule shell by incorporating it into a fill material matrix. The fill material acts as a barrier that separates the moisture-sensitive probiotic from the humid capsule shell environment, preventing moisture-induced degradation while maintaining the desired soft capsule form factor for patient compliance.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The fill material serves as an intermediary substance between the probiotic supplement and the capsule shell. This intermediate layer protects the probiotic from direct exposure to moisture while still allowing the capsule to maintain its soft, chewable properties. The fill material mediates the interaction between moisture and probiotic, preventing harmful effects.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If elaborate microencapsulation processes are used to stabilize probiotics, then probiotic viability is improved, but manufacturing cost and complexity increase significantly

Engineering Contradiction:
Improveprobiotic stabilityVSAvoidmanufacturing process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent changes the formulation parameters of the fill material to achieve probiotic stabilization. By adjusting the composition, moisture content, and physical properties of the fill material, the invention achieves effective probiotic protection through a simple mixing and encapsulation process, avoiding complex multi-step microencapsulation manufacturing while maintaining high probiotic viability.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If soft capsules are made with traditional gelatin and plasticizers, then ease of swallowing is improved, but temperature and humidity sensitivity causes capsules to become overly soft or brittle

Engineering Contradiction:
Improveease of swallowingVSAvoidcapsule stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent employs composite materials in the capsule shell formulation, combining gelatin with alternative plasticizers and stabilizing agents. This composite approach creates a capsule shell that maintains the desired soft, chewable properties for ease of swallowing while simultaneously improving temperature and humidity stability to prevent excessive softening or brittleness under varying storage conditions.

Inventive Principle:
Principle #40Composite materials

AI summary

Methods of making orally available softgels includes pre-wetting a probiotic with an edible oil to produce a wetted supplement, wherein the edible oil is present in a range of 25% to 75% by weight of a total weight of the probiotic and edible oil, heating the wetted supplement to a temperature in a range of 35° C. to 40° C., blending the wetted supplement and a molten chocolate component together to produce a liquid fill material, encapsulating the liquid fill material in a softgel coating to produce an orally available softgel, and cooling the orally available softgel to have a softgel capsule shell comprising 5% to 15% by weight water. The fill material is a solid at room temperature in the cooled orally available softgel.
