Peptidomics-Based Food Quality Evaluation Service

Food quality evaluation has traditionally relied on chemical, physical, and microbiological indicators to assess freshness, safety, nutritional value, and organoleptic properties. However, these conventional methods often fail to capture the subtle biochemical changes that occur during food processing, storage, or spoilage. Recent advances in omics technologies have introduced peptidomics as a powerful tool to complement and enhance food quality analysis. Peptidomics refers to the comprehensive study of peptides, short amino acid sequences generated through enzymatic or chemical cleavage of proteins. These peptides serve as sensitive markers of biological activity, degradation processes, microbial contamination, and enzymatic modifications. By profiling the peptidome of food samples, researchers can gain deeper insights into quality, safety, processing history, and authenticity.

Service at MtoZ Biolabs

MtoZ Biolabs offers a dedicated Peptidomics-Based Food Quality Evaluation Service that combines high-resolution mass spectrometry, expert bioinformatics analysis, and optional functional screening. Our Peptidomics-Based Food Quality Evaluation Service platform enables accurate identification and quantification of peptides, revealing molecular-level changes that reflect food freshness, degradation, adulteration, and bioactivity. This service supports food producers, quality control labs, regulatory agencies, and researchers in ensuring product integrity and consumer safety.

The key components of our offering include:

💠Comprehensive Peptidome Profiling

We perform global profiling of peptides present in food samples at different processing or storage stages, enabling detailed molecular characterization of food quality status.

💠Spoilage and Degradation Monitoring

By identifying peptides formed during protein degradation, we assess spoilage levels and evaluate product shelf life and stability.

💠Processing History and Fermentation Assessment

We characterize proteolytic fingerprints linked to specific processing steps, fermentation phases, or microbial enzymatic activity to ensure batch consistency and product traceability.

💠Detection of Adulteration or Quality Loss

Unexpected peptide profiles may indicate the addition of undeclared ingredients, substandard raw materials, or improper handling, helping detect food fraud or authenticity issues.

💠Bioactivity Evaluation

Optionally, we assess the presence of bioactive peptides that contribute to the functional value of the product, supporting claims related to health benefits or nutritional enhancement.

💠Nutritional Value Assessment

We analyze peptide composition to evaluate the nutritional quality of food products, offering insights into protein digestibility, amino acid balance, and functional peptide content.

💠Allergen Detection

By identifying peptide fragments associated with known food allergens, we support allergen surveillance and labeling compliance, helping reduce consumer risk and ensure regulatory safety.

Analysis Workflow

1. Sample Preparation: Food samples are processed to extract peptides suitable for downstream analysis.

2. Peptide Enrichment: Peptides are purified to remove interfering substances and concentrate relevant molecules.

3. Mass Spectrometry Analysis: High-resolution LC-MS/MS is used to identify and quantify peptides across samples.

4. Data Processing and Interpretation: Identified peptides are analyzed for quality indicators and functional relevance using specialized bioinformatics tools.

5. Report Generation: Results are compiled into a comprehensive report with visualizations and expert insights to support quality assessment and decision-making.
