GB/T 14454.6-2008Fragrance/Flavor substances -- Quantitative evaluation of residue on evaporation (English PDF)

Foreword

GB/T 14454, Fragrance/Flavor substances, consists of the following parts:

-- Part 1: Fragrance/Flavor substances - Preparation of test samples;

-- Part 2: Fragrance/Flavor substances - Method for valuation of odour;

-- Part 4: Fragrance/Flavor substances - Determination of refractive index;

-- Part 5: Fragrance/Flavor substances - Determination of optical rotation;

-- Part 6: Fragrance/Flavor substances - Quantitative evaluation of residue

on evaporation;

-- Part 7: Fragrance/Flavor substances - Determination of freezing point;

-- Part 11: Fragrance/Flavor substances - Determination of content of

phenols;

-- Part 12: Fragrance/Flavor substances - Method for determination of trace

chlorinated compounds;

-- Part 13: Fragrance/Flavor substances - Determination of carbonyl value

and carbonyl compounds content;

-- Part 14: Fragrance/Flavor substances - Preparation of standard solution,

test solution and indicator solution;

-- Part 15: Oil of sassafras - Determination of safrole and isosafrole content

- Gas chromatographic method on packed columns.

This Part is Part 6 of GB/T 14454.

This Part modifies and adopts ISO 4715:1978, Essential oils - Quantitative

evaluation of residue on evaporation. Compared with ISO 4715:1978, the main

technical differences are as follows:

-- Remove the sampling method of ISO 4715:1978;

-- Add the evaluation of residue on evaporation for isolated and synthetic

fragrance.

This Part is a revision of GB/T 14454.6-1993, Fragrance/Flavor substances -

Quantitative evaluation of residue on evaporation. Compared with GB/T

14454.6-1993, this Part mainly adds relevant contents of the test report.

This Part was proposed by China National Light Industry Council.

Fragrance/Flavor substances -

Quantitative evaluation of residue on evaporation

1 Scope

This part of GB/T 14454 specifies the evaluation method for the residue on

evaporation of fragrance.

This section applies to essential oils, isolated and synthetic fragrances that

contain residues on evaporation.
