Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The beer brewing industry faces the challenge of premature yeast flocculation (PYF) during fermentation, leading to poor beer quality due to slow sugar degradation and acetaldehyde reduction, and existing detection methods are time-consuming and lack predictive capabilities for the malt production process.
Innovation Solution
A malt PYF regulation method based on gene expression analysis during the malting process, involving transcriptome analysis to identify tracking genes, using specific primers for reverse transcription and multiplex PCR, and applying principal component analysis to predict PYF performance, allowing for process adjustments to improve malt quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional empirical methods are used to control malt PUF, then the control process is simple, but the precision and stability of malt PUF content are insufficient
Solution Approach 1:
The patent applies preliminary action by establishing a gene expression regulation model before actual malting production. The model includes building a prediction system using gene expression data (such as LPCAT3, DGAT2, AGPAT6) to forecast malt PUF content, allowing operators to adjust brewing parameters in advance to achieve desired PUF levels, rather than relying on empirical trial-and-error methods.
Solution Approach 2:
The patent implements feedback control by continuously monitoring gene expression levels during malting and using this information to adjust processing parameters. The system measures gene expression, compares it with target values, and automatically adjusts malting conditions to maintain optimal PUF production, creating a closed-loop control system that improves precision while managing complexity through automation.
2Manufacturing precision
If gene expression regulation model is implemented, then the control precision of malt PUF is improved, but the operation complexity increases
Solution Approach 1:
The patent applies self-service by designing an automated control system that performs gene expression analysis and automatically adjusts malting parameters without requiring extensive manual intervention. The system self-regulates by using the gene expression data to trigger appropriate control actions, reducing the operational burden on personnel while maintaining high precision in malt PUF content control.
3Measurement precision
If multiple gene expression indicators are monitored, then the prediction accuracy of malt PUF increases, but the detection complexity increases
Solution Approach 1:
The patent merges multiple gene expression detection functions into a unified analysis system. Instead of separately analyzing each gene (LPCAT3, DGAT2, AGPAT6, etc.), the system combines their expression data into an integrated prediction model that forecasts malt PUF content. This consolidation reduces detection complexity by providing a single comprehensive output from multiple input parameters.
