DNA Methylation Profiling for Tamper-Resistant Meat Origin Certification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack a reliable and tamper-resistant means to trace the origin and certification of animal-derived products, particularly meat, which is crucial for ensuring compliance with dietary restrictions and quality standards, as existing audits are easily compromised and visual inspections are ineffective.
Innovation Solution
A method utilizing DNA methylation profiling to identify specific 'epigenetic fingerprints' that distinguish animal-derived products based on their slaughter methods and suppliers, allowing for accurate tracing of the product's source and certification, including differentiation between Kosher and Halal practices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional audit-based certification methods are used, then certification can be obtained, but the certification is easily tampered with and lacks reliability
Solution Approach 1:
The patent replaces the mechanical/physical audit system with a biological molecular detection system. DNA methylation profiles serve as inherent biological markers that cannot be easily altered or faked, substituting the manual audit process with automated molecular fingerprinting that provides tamper-proof verification of slaughter methods and origin.
Solution Approach 2:
The patent creates a molecular copy or fingerprint of the animal's biological state at the time of slaughter through DNA methylation profiling. This epigenetic signature serves as a permanent record that can be analyzed later to verify slaughter conditions, effectively copying the biological evidence without requiring physical presence during the slaughter process.
2Measurement precision
If visual inspection methods are used to verify meat origin and certification, then the process is simple, but the method is ineffective and cannot accurately distinguish between different slaughter practices
Solution Approach 1:
The patent shifts from visual parameter inspection (color, texture, appearance) to molecular parameter analysis (DNA methylation patterns). By changing the detection parameters from macroscopic visual characteristics to microscopic epigenetic markers, the system achieves high precision in distinguishing between different slaughter methods and origins that are invisible to the human eye.
Solution Approach 2:
The patent introduces DNA methylation analysis as an intermediary between the meat product and the verification process. Instead of directly observing physical characteristics, the method uses molecular biomarkers as intermediaries that carry information about slaughter conditions, enabling indirect but accurate detection of origin and certification status.
3Reliability
If certificates are based on farm audits, then certification can be established, but surveillance is spotty and limited to audits allowing tampering
Solution Approach 1:
The patent performs preliminary action by capturing the biological signature of the animal at the moment of slaughter through DNA methylation profiling. This creates a timestamped molecular record that permanently documents the slaughter conditions and origin, eliminating the need for continuous surveillance and enabling verification at any later time without additional time loss.
4Measurement precision
If no molecular identification method is used, then the system remains simple, but there is no reliable means of tracing animal product origins
Solution Approach 1:
The patent segments the complex task of origin verification into specific measurable components: DNA extraction, methylation pattern analysis at specific genomic loci, and comparison against reference databases. By breaking down the identification process into discrete molecular markers and analysis steps, the system achieves high precision while managing complexity through standardized protocols.
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
Enables reliable and accurate certification of animal-derived products by correlating DNA methylation patterns with specific slaughter practices, ensuring compliance with dietary regulations and quality standards, thereby enhancing consumer trust and transparency in the food supply chain.
Implementation Method 1
DNA methylation patterns of animals contain important information about their rearing conditions. Recent studies have shown that DNA methylation patterns are maintained postmortem and are consistent regardless of the level of decomposition of the sample.

AI summary
The present invention relates to a method of determining the supplier from which a test animal-derived product sample originates, the method comprising the steps of:(a) determining a test methylation profile of one or more pre-selected methylation sites within the genomic material contained in the test animal-derived product sample; and(b) comparing the test methylation profile determined in (a) with a panel of predetermined reference methylation profiles of the same biological taxon of the test animal from which the product sample derives, wherein each of the predetermined reference methylation profiles is from a different reference animal and/or different supplier,wherein if the test methylation profile of (a) is significantly similar to one of the predetermined reference methylation profiles, the test animal-derived product sample is confirmed of originating from a first supplier from which a first reference animal with the predetermined reference profile is obtained.
