Sustained-Release Sugar Alcohol Additive for Colon-Specific Propionate Synthesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sugar alcohols like fructo-oligosaccharides and polysaccharides have low enteral utilization rates and can cause metabolic disorders and gas issues due to rapid propionate generation, leading to hyperglycemia, obesity, and insulin resistance.
Innovation Solution
An enteral sustained-release sugar alcohol additive with an inner layer of xylitol and agar, and an outer layer of carrageenan or gellan gum, xanthan gum, vitamin B12, and fermented bifidobacterium, propionibacterium, or lactobacillus, which allows for slow release in the intestinal tract and fixed-point release in the colon, promoting high-concentration propionate synthesis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fructo-oligosaccharide or polysaccharide is used to generate propionate in intestinal tract, then propionate generation function is achieved, but enteral utilization rate is low and gas production problems occur
Solution Approach 1:
The patent divides the sugar alcohol additive into an inner layer containing xylitol and agar, and an outer layer containing carrageenan or gellan gum with fermented bacteria. This segmented structure enables controlled release: the inner layer provides sustained sugar alcohol release while the outer layer contains probiotics that convert released sugars into propionate locally in the colon, thereby improving enteral utilization rate while maintaining propionate generation function.
Solution Approach 2:
The patent pre-ferments bacteria (bifidobacterium, propionibacterium, or lactobacillus) with sugars during manufacturing to create a preliminary biochemical transformation. This preliminary action ensures that when the additive reaches the intestinal tract, the pre-conditioned bacteria are ready to efficiently convert released sugars into propionate, improving both utilization rate and propionate generation reliability.
2Reliability
If exogenous propionate is ingested to participate in gluconeogenesis, then metabolic function is improved, but hyperglycemia and insulin resistance occur after long period ingestion
Solution Approach 1:
The patent implements periodic action through sustained-release technology that gradually releases xylitol and sugars over time in the intestinal tract. This continuous, controlled release provides periodic substrate supply to probiotics, which in turn generate propionate in a sustained manner rather than causing sudden spikes. This periodic propionate generation maintains metabolic function while avoiding the harmful effects of excessive or intermittent propionate intake.
Solution Approach 2:
The patent introduces fermented probiotics (bifidobacterium, propionibacterium, or lactobacillus) as intermediary organisms that mediate the conversion of sugar alcohols into propionate within the colon. This intermediary mechanism ensures propionate is generated locally at the target site rather than being delivered systemically, maintaining reliable propionate levels for metabolism while preventing the harmful effects associated with exogenous propionate supplementation.
3Reliability
If fructo-oligosaccharide is used to generate propionate, then propionate synthesis is achieved, but excess gas generation and metabolic disorder occur
Solution Approach 1:
The patent applies local quality by concentrating the propionate synthesis function specifically in the outer layer containing fermented bacteria, while the inner layer focuses on sustained sugar release. This spatial differentiation ensures that sugar fermentation and propionate synthesis occur locally in the colon where probiotics reside, rather than throughout the entire intestinal tract. This localized approach improves propionate synthesis efficiency while minimizing gas generation by confining fermentation to the colon environment.
