Описание (английский):

The stable isotope ratios of carbon, hydrogen, oxygen and nitrogen can be used to obtain information about the origin of bio-based feedstock and characteristics of production processes of bio-based products. However, no or limited attention for the use of the elements nitrogen and sulphur is given in this document due to the fact that these applications are not yet available. This Technical Report provides an overview of existing applications of isotope ratio analysis of carbon, hydrogen, oxygen and nitrogen that are relevant to the analysis of bio-based feedstocks, products and production processes

Abstract

Overview - CEN/TR 17674:2021 (Stable isotope ratios for bio-based verification)

CEN/TR 17674:2021 is a Technical Report from CEN/TC 411 that provides an overview of existing applications using stable isotope ratios of carbon (C), hydrogen (H), oxygen (O) and nitrogen (N) to verify the origin of bio-based feedstock and to characterise production processes of bio-based products. The report summarises laboratory methods, typical isotopic fingerprints (plant pathways C3/C4/CAM), measurement approaches and practical use-cases; it notes limited coverage of nitrogen and sulphur due to current lack of applications.

Key topics and technical requirements

Measurement technologies: isotope ratio mass spectrometry (IRMS) in bulk and compound-specific modes:
- EA‑IRMS (Bulk Stable Isotope Analysis, BSIA) for whole-sample elemental isotopes.
- GC‑C/P‑IRMS or LC‑co‑IRMS for Compound Specific Isotope Analysis (CSIA).
Data reporting: isotopic composition reported in delta (δ) notation relative to international standards.
Analytical performance (typical uncertainties quoted):
- δ13C: ±0.3 ‰, δ15N: ±0.3 ‰, δ2H: ±5 ‰, δ18O: ±1 ‰.
Isotopic fingerprints:
- C3 plants: δ13C ≈ −20 ‰ to −33 ‰
- C4 plants (e.g., maize, sugarcane): δ13C ≈ −10 ‰ to −12 ‰
- CAM plants (e.g., vanilla, pineapple): δ13C ≈ −10 ‰ to −24 ‰
Authenticity and monitoring: examples include detection of synthetic vanillin vs. natural, honey adulteration (C4 sugar detection), and monitoring of industrial production routes.

Applications and who uses this standard

Use cases:
- Verification of bio-based feedstock origin and claims of bio-based content.
- Authenticity testing of flavors, food ingredients, bio-plastics, bio-rubbers, biofuels, biosurfactants, biocosmetics and other bio-products.
- Monitoring and verification of industrial production pathways and raw material sourcing.
Primary users:
- Analytical laboratories and IRMS specialists
- Producers, suppliers and purchasers of bio-based materials
- Certification bodies, inspection organizations and regulators
- R&D teams developing bio-based products and sustainability audits

Related standards and references

EN 16575:2014 (Bio-based products - Vocabulary) - normative reference in the report.
Examples of referenced methods: CEN ENV 12140/12141/12142 (stable isotope analysis for fruit juices) and AOAC official methods for detection of C4 plant sugars in honey.
Output is part of the CEN/TC 411 suite addressing bio-based content, LCA and sustainability.

CEN/TR 17674:2021 is a practical reference for integrating stable isotope analysis, IRMS techniques, and isotopic fingerprinting into quality control, authenticity verification and supply‑chain transparency for bio-based products.
