Overview

ISO 13685:1997 specifies a validated analytical method for determining the main pungent components of ginger - gingerols ([6]-G, [8]-G, [10]-G) and corresponding shogaols ([6]-S, [8]-S, [10]-S) - in dried ginger and ginger oleoresins using high-performance liquid chromatography (HPLC) in reversed phase. The standard was prepared by ISO/TC 34/SC 7 (Spices and condiments) and includes informative annexes (A–E) with chemical structures, typical chromatograms, standard curves and interlaboratory test data.

Key topics and requirements

Scope: Quantification of [6], [8], [10]-gingerols and shogaols in dried ginger and oleoresins by reverse‑phase HPLC with UV detection at 280 nm.

Sample preparation: Grinding (ISO 2825), moisture correction (ISO 939), methanol extraction at ambient temperature, partial concentration under reduced pressure for dried ginger; direct dissolution for oleoresins.

External standard: Nonanoic acid vanillylamide (NVA) used as an external standard; preparation and calibration procedures are defined.

Chromatography conditions: ODS (C18) column (approx. 250 × 4.6 mm, 5 μm), mobile phase acetonitrile : water (with 1% acetic acid) ~65:35 before degassing, flow rate 1.0 mL/min, detection at 280 nm. Specific run times differ for dried ginger (~17 min) and oleoresins (~40 min).

Quantification: Peak-area based calculation using response factors derived from NVA; molecular-mass corrections provided for each compound. Formulae and example calculations included.

Validation and performance: Method validated via two international interlaboratory tests (seven labs); repeatability limits indicated (e.g., dried ginger [6]-G ≈ 2% absolute difference).

Safety notes: Warnings about acetonitrile toxicity and NVA irritation; use analytical/HPLC grade reagents.

Applications and users

Quality control laboratories in spice, flavour and food ingredient industries.

Analytical chemistry labs performing routine or forensic spice analysis.

R&D teams developing ginger extracts, oleoresins, nutraceuticals and functional foods.

Regulatory and certification bodies assessing spice composition and authenticity. Practical uses include batch release testing, specification compliance, process monitoring and research into pungency/active compound profiles.
