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 multi-step enzymatic treatment methods are used to produce oat-based products rich in β-glucan and isomalto-oligosaccharide, then the product can achieve high content of these functional components, but the production process becomes complex and time-consuming with high production costs
Solution Approach 1:
The patent combines multiple enzymatic treatments (α-amylase, β-amylase, and trans-glucosidase treatments) into a single integrated process step, where all three enzymes work simultaneously or sequentially in one reaction system to produce both β-glucan and isomalto-oligosaccharide, thereby simplifying the production process while maintaining high functional component content
Solution Approach 2:
The enzymatic system is designed to perform multiple functions simultaneously: α-amylase breaks down starch, β-amylase produces β-glucan, and trans-glucosidase produces isomalto-oligosaccharide, allowing one process to achieve multiple product objectives that traditionally required separate treatment steps
2Quantity of substance
If traditional enzymatic treatment methods are used, then functional components can be extracted, but the natural flavor and aroma of oats are lost
Solution Approach 1:
The patent optimizes enzymatic reaction parameters including temperature (maintained at 50-60°C which preserves aromatic compounds), pH levels, and enzyme dosages to achieve effective hydrolysis while minimizing degradation of flavor and aroma compounds. The controlled parameter changes allow functional component extraction without excessive thermal or chemical processing that would strip natural characteristics
3Quantity of substance
If extended enzymatic treatment time is used to maximize functional component yield, then higher content of β-glucan and isomalto-oligosaccharide is achieved, but production time and costs increase
Solution Approach 1:
The patent employs continuous enzymatic hydrolysis where substrates are continuously converted to products without interruption, maintaining optimal reaction conditions throughout the process. This continuous action maximizes conversion efficiency within a condensed time frame, achieving high yields without extended treatment periods
Solution Approach 2:
By optimizing temperature, pH, and enzyme concentration parameters, the reaction kinetics are enhanced to achieve maximum functional component yield in reduced time. The parameter optimization ensures rapid and complete hydrolysis without requiring prolonged treatment

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.
