Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing oat-based dairy alternatives face challenges such as high production costs, complex processing steps, loss of natural oat flavor, and inadequate liquid uniformity, foaming capacity, and emulsifying capacity, while also failing to retain complete nutrients and enhance immunity.
Innovation Solution
A method involving micro-milling and quadri-enzyme hydrolysis using α-amylase, β-amylase, transglutaminase, and transglucosidase to process oats, which results in oligo-saccharide oat compositions and drinks with improved properties like liquid uniformity, foaming capacity, and immunomodulatory efficacy, retaining natural oat flavor and nutrients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional enzyme treatment methods are used to produce oat-based dairy alternatives, then production costs are reduced, but liquid uniformity, foaming capacity, and emulsifying capacity are insufficient
Solution Approach 1:
The patent divides the enzyme treatment process into four distinct stages using different enzymes: α-amylase for starch breakdown, β-amylase for maltose production, transglucosidase for oligosaccharide formation, and transglutaminase for protein crosslinking. This segmentation allows each enzyme to target specific components, improving liquid uniformity and foaming capacity while maintaining cost-effectiveness through optimized processing steps.
2Quantity of substance
If complex processing steps are used to obtain high yield oat β-glucan, then functional ingredient content is improved, but processing complexity and production cost increase
Solution Approach 1:
The patent combines multiple enzyme treatments (α-amylase, β-amylase, transglucosidase, and transglutaminase) into a single integrated processing sequence. This merging approach achieves high yield oat β-glucan extraction with improved functional ingredient content while reducing processing complexity compared to conventional multi-step methods, as all enzyme treatments occur in sequence within one processing framework.
3Quantity of substance
If extensive enzyme treatment is used to enhance functional ingredients, then isomaltooligosaccharide content increases, but enzyme treatment time and production cost increase
Solution Approach 1:
The patent employs periodic enzyme treatment with four distinct enzyme stages added sequentially: α-amylase first, followed by β-amylase, then transglucosidase, and finally transglutaminase. This periodic action allows each enzyme to work optimally for its specific function, achieving high isomaltooligosaccharide content while minimizing total treatment time compared to using a single enzyme for extended periods.
4Ease of manufacture
If conventional processing methods are used to produce oat drinks, then production cost is reduced, but natural oat flavor is lost
Solution Approach 1:
The patent optimizes processing parameters including enzyme addition sequences, treatment temperatures, and pH conditions to preserve natural oat flavor compounds. By carefully controlling these parameters during the four-stage enzyme treatment, the method maintains cost-effectiveness while preventing loss of volatile aromatic compounds that give oats their characteristic flavor.
5Reliability
If filtration operations are used to improve product clarity, then liquid uniformity is improved, but nutrient retention and raw material utilization rate decrease
Solution Approach 1:
The patent replaces mechanical filtration operations with enzymatic treatment mechanisms. The four enzymes (α-amylase, β-amylase, transglucosidase, and transglutaminase) chemically break down and modify oat components to achieve liquid uniformity without physical filtration, thereby retaining complete nutrients and maximizing raw material utilization rate.
