Enzyme-Prebiotic Combinations for Selective Probiotic Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current probiotic dietary supplements face challenges in effectively multiplying in the intestinal tract due to inadequate nutrient support and competition from pathogenic bacteria, with existing carbohydrate-based prebiotics often causing adverse effects such as flatulence and allergic reactions, and failing to preferentially stimulate probiotic growth without stimulating undesirable bacteria.
Innovation Solution
The use of enzymes like α-galactosidase and β-glucanase in combination with iso-malto oligosaccharides to generate shorter chain oligosaccharides that preferentially enhance the growth and activity of lactobacilli and bifidobacteria, avoiding significant glucose production that can stimulate undesirable bacteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If carbohydrate-based prebiotics (FOS or inulin) are used to stimulate probiotic growth, then probiotic multiplication is enhanced, but pathogenic bacteria growth is also stimulated and adverse effects occur
Solution Approach 1:
The patent applies local quality by creating a microenvironment in the intestinal tract that is specifically favorable for probiotics through the use of non-carbohydrate prebiotics. These prebiotics provide nutrients that selectively support probiotic bacteria (Lactobacillus and Bifidobacterium) while being less suitable for pathogenic bacteria, thus creating localized nutritional conditions that favor beneficial microbes without broadly stimulating harmful ones.
Solution Approach 2:
The patent changes the chemical parameter of the prebiotic substance from carbohydrate-based (FOS, inulin) to non-carbohydrate-based compounds. This parameter change fundamentally alters how the prebiotic interacts with different bacterial species, allowing it to stimulate probiotics through alternative metabolic pathways that do not involve glucose production, thereby avoiding the stimulation of pathogenic bacteria that thrive on glucose.
2Productivity
If large quantities of FOS or inulin are administered to achieve probiotic stimulation, then probiotic growth is enhanced, but the dosage becomes impractical for capsule or tablet delivery
Solution Approach 1:
The patent changes the chemical nature of the prebiotic from carbohydrates to non-carbohydrate compounds, which fundamentally alters the dosage requirements. Non-carbohydrate prebiotics provide efficient nutrient sources for probiotics at much lower concentrations, reducing the required dosage from grams to milligrams, making the formulation practical for capsule and tablet delivery systems.
Solution Approach 2:
The patent employs prebiotic substances that are highly efficient at stimulating probiotic growth at low concentrations, replacing the need for large quantities of less efficient carbohydrate prebiotics. This allows for compact, practical dosing in supplemental forms while maintaining effective probiotic stimulation.
3Productivity
If FOS or inulin are used as prebiotics, then probiotic bacteria are stimulated, but flatulence and abdominal pain occur in some users
Solution Approach 1:
The patent changes the chemical composition of the prebiotic from fermentable carbohydrates to non-carbohydrate compounds. This parameter change eliminates the excessive fermentation in the colon that causes gas production, flatulence, and abdominal pain, while still providing effective nutritional support for probiotic bacteria through alternative metabolic pathways.
4Productivity
If inulin is used to stimulate bifidobacteria, then probiotic growth is enhanced, but severe allergic reactions occur in some people
Solution Approach 1:
The patent changes the prebiotic substance from inulin (a carbohydrate polymer) to non-carbohydrate compounds with different chemical structures. This parameter change eliminates the allergenic properties associated with inulin while preserving the ability to stimulate bifidobacteria growth through alternative nutritional mechanisms that do not trigger immune responses.
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
This approach allows for effective stimulation of probiotic growth and activity at lower dosages without adverse effects, providing a non-carbohydrate prebiotic solution that preferentially supports lactobacilli and bifidobacteria while minimizing growth of pathogenic bacteria.
Implementation Method 1
The enzymes α-galactosidase and β-glucanase react with the fiber prebiotics to generate shorter chain oligosaccharides
Implementation Method 2
the probiotic can metabolize the reaction product(s) to enhance its growth and activity

AI summary
This disclosure relates to enhancing growth and/or activity of lactobacilli using a prebiotic formulation which includes iso-malto oligosaccharides and α-galactosidase; and to enhancing growth and/or activity of bifidobacteria using a prebiotic formulation which includes iso-malto oligosaccharides and β-glucanase. Other combinations of fibers and enzymes are described below which also stimulate growth and activity of lactobacilli or bifidobacteria. These combinations of enzymes and prebiotics can be taken separately or added to foods, including desserts.
