Vegetarian Capsule Stability via Biphasic Moisture Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for animal-gelatin-free capsules that are made from natural ingredients and provide mechanical and dimensional stability, especially for filling hygroscopic materials without crosslinking, while maintaining safety and avoiding microbial activity.
Innovation Solution
A biphasic system using vegetable derivatives such as cellulose, gum, metallic elements, maltol, seaweed, and galactomannan extracts, combined with water, is used to create clear hard vegetarian two-piece capsules through a dipping method, maintaining temperatures below 80°F and employing hot air to lock moisture, ensuring stability and resistance to humidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gelatin or animal-derived substances are used to make capsules, then mechanical stability and structural integrity are achieved, but safety risks increase due to associations with BSE and other animal health dangers
Solution Approach 1:
The patent removes gelatin and animal-derived substances from the capsule formulation entirely, extracting the harmful element while maintaining the essential function of providing a stable capsule structure through alternative plant-based ingredients
Solution Approach 2:
The invention uses a composite formulation combining multiple plant-based ingredients (cellulose, gum, metallic element, maltol extract, seaweed extract, galactomannan extract) to create a capsule that achieves mechanical stability without relying on single animal-derived materials
2Adaptability or versatility
If conventional capsule materials are used, then manufacturing simplicity is maintained, but the ability to fill hygroscopic materials without crosslinking is compromised
Solution Approach 1:
The patent modifies the chemical and physical parameters of the capsule material by incorporating specific plant-based compounds with controlled hygroscopic properties, allowing the capsule to maintain stability when filled with hygroscopic materials without requiring crosslinking
Solution Approach 2:
The formulation acts as an intermediary system that mediates between the capsule structure and hygroscopic fill materials, using the moisture-locking properties of the plant-based composition to prevent unwanted interactions while maintaining structural integrity
3Productivity
If temperature control above 80°F is used in capsule manufacturing, then processing efficiency increases, but moisture loss and dimensional stability deteriorate
Solution Approach 1:
The patent changes the temperature parameter to below 80°F and incorporates moisture-locking ingredients into the formulation, allowing the capsule to maintain dimensional stability at lower temperatures through the chemical properties of the plant-based materials rather than relying on high-temperature processing
4Strength
If crosslinking is used to improve capsule stability, then mechanical strength increases, but the natural composition and safety profile are compromised
Solution Approach 1:
The patent converts the potential harm of needing crosslinking for stability into a benefit by using naturally occurring moisture-locking properties of plant-based ingredients to achieve the same stability effect without crosslinking, thereby maintaining safety and natural composition
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution produces clear, stable, and resistant capsules that inhibit microbial activity and can fill hygroscopic materials, maintaining mechanical and dimensional stability, and preventing crosslinking, while being free from animal-derived materials and safe for use with various pharmaceutical and nutritional contents.
Implementation Method 1
bonding or locking the water to the cellulose, rendering each capsule piece to have an outer surface resistant to humidity and moisture
Implementation Method 2
The water can be blown away using blown hot air. The blown hot air can be at a temperature from about 70 degrees Celsius to about 77 degrees Celsius, thereby bonding or locking the water to the cellulose

AI summary
A method for making clear hard vegetarian gelatin free two piece capsules by creating the first phase of the biphasic system using seaweed extract, gellan gum, metallic element, maltol extract, seaweed extract and water. A filler is created for the first phase of the biphasic network by blending water, galactomannan extract, and cellulose. The filler is then mixed into the system forming a biphasic system, a first pin is then dripped into the blend and then a second pin is then dripped into the blend. Blowing hot air on the dipped pins, which then blows away water on the outer surface of the dipped pins to bond and lock moisture to the cellulose. A large diameter capsule piece is removed from the first pin and a small diameter capsule piece is removed from the second pin, wherein each capsule piece has an outer surface which is mechanically and dimensionally stable.
