Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing oat-based products rich in β-glucan and isomalto-oligosaccharide are complex, time-consuming, and result in high production costs, while also losing the natural flavor and aroma of oats.
Innovation Solution
A process combining micronized milling and tri-enzymatic hydrolysis using α-amylase, β-amylase, and trans-glucosidase to produce a stable oat-based drink with enhanced β-glucan and isomalto-oligosaccharide content, retaining the natural flavor and aroma of oats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional enzymatic treatment methods are used to produce oat-based products rich in β-glucan and isomalto-oligosaccharide, then the nutritional content is improved, but the production time is extended and production costs increase
Solution Approach 1:
The patent applies preliminary action by using ultra-fine milling (particle size 0.5-5 μm) before enzymatic treatment to pre-process the oat material. This preliminary size reduction creates a much larger surface area for enzyme action, allowing the subsequent enzymatic hydrolysis to proceed much faster while still achieving high yields of β-glucan and isomalto-oligosaccharide, thus resolving the contradiction between nutritional content and production time
Solution Approach 2:
The patent changes the particle size parameter from conventional sizes to ultra-fine particles (0.5-5 μm), which fundamentally alters the enzymatic hydrolysis kinetics. This parameter change enables the enzymatic treatment to complete in significantly reduced time while maintaining or enhancing the production of beneficial carbohydrates, thereby resolving the time-nutrition contradiction
2Quantity of substance
If traditional enzymatic treatment methods are used to produce oat-based products rich in β-glucan and isomalto-oligosaccharide, then the nutritional content is improved, but the production costs increase
Solution Approach 1:
The ultra-fine milling step performed before enzymatic treatment serves as a preliminary action that enables faster hydrolysis. This reduces the enzymatic treatment time from several hours to a fraction of that time, thereby reducing enzyme consumption costs and energy costs, while still achieving high nutritional content, thus resolving the contradiction between nutritional quality and manufacturing cost
Solution Approach 2:
The patent replaces conventional mechanical grinding with ultra-fine milling technology that achieves particle sizes of 0.5-5 μm. This mechanical substitution creates material with vastly increased surface area, enabling much more efficient enzymatic action and shorter processing times, which reduces overall production costs while maintaining high nutritional output
3Ease of manufacture
If conventional milling is used to prepare oat slurry, then the processing is simple, but the natural flavor and aroma of oats are lost
Solution Approach 1:
The patent changes the particle size parameter to ultra-fine range (0.5-5 μm) which fundamentally alters how the oat material interacts with water and enzymes. This parameter change enables complete dissolution and uniform distribution without requiring prolonged heating or aggressive processing that would degrade flavor compounds, thus maintaining natural taste while achieving thorough processing
Solution Approach 2:
The patent replaces conventional thermal processing methods with ultra-fine mechanical milling followed by enzymatic hydrolysis. This substitution avoids high-temperature treatment that destroys volatile flavor compounds and aromatic substances, preserving the natural oat flavor and aroma while still achieving complete processing and high nutritional content

Function Achieved in This Case
The process significantly shortens production time, reduces costs, and results in a product that effectively lowers cholesterol, triglycerides, and fasting blood glucose levels, while improving gastrointestinal function and retaining the natural flavor of oats.
Implementation Method 1
treating the oat slurry with β-amylase to a viscosity of about 1 to 0.1 Pas, and with α-amylase and trans-glucosidase to a viscosity of 0.1 to 0.01 Pas
Implementation Method 2

AI summary
The invention relates to a tri-enzyme hydrolysis method for preparing an oligo-saccharide enhanced oat-based drink product useful in lowering cholesterol, triglyceride, blood sugar and improving gastrointestinal function which comprises not only oat β-glucan and but also a higher amount of isomalto-oligosacchride. In accordance with the invention, whole grains of oats are micronized to an average particle size of 100 microns prior to enzyme treatments, and a product of creamy milk-like texture is obtained without filtration so that nutrients of the whole grains of oats are retained. This invention enhances the value of oat-based processing to yield additional health-associated content and illness (such as hyperlipidaemia and hyperglycemia) prevention efficacy that are beyond the potential of oats per se.
