Embodiment 1

[0018] 2-Heptanone, 2-octanone, 2-nonanone and 2-undecanone were each dissolved in crude palm oil at a concentration of 500 ppb. 10 ml of the marked oil were then extracted with 5 ml of methanol while stirring at 60° C. for 1 hour. Extracts containing markers were removed. To this extract, 5 ml of 1 mg / ml O-(2,3,4,5,6-pentafluorobenzyl) hydroxylamine hydrochloride (PFBHA) aqueous solution was added, and incubated at 60°C under vigorous stirring for 2 Hour. The reaction mixture was then extracted with 2.5 ml of chloroform while stirring at 60°C for 20 minutes. The chloroform layer containing the derivative was removed and dried through a cotton wool plug before analysis using GC / MS in negative chemical ionization (NCI) mode. The GC / MS instrument used was equipped with J&W Scientific TM HP-5 capillary column (30m long, 0.32mm inner diameter, 0.25mm stationary phase thickness) with Agilent 5973 mass selective detector 6890GC. The initial furnace temperature was 50°C, held ...

Embodiment 2

[0021] 2-methyl-3-heptanone, 6-undecanone, ethyl vinyl ketone, 5-methyl-2-hepten-4-one and 2,6-dimethyl-4-heptanone Each was dissolved in crude palm oil at a concentration of 500 ppb. Then 10 ml of the marked oil were extracted with 5 ml of methanol while stirring at 60° C. for 1 hour. Extracts containing markers were removed. To this extract was added 5 ml of a 1 mg / ml aqueous solution of O-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine hydrochloride (PFBHA), and incubated at 60°C for 2 hours. The reaction mixture was extracted with 2.5 ml of chloroform while stirring at 60°C for 20 minutes. The chloroform layer containing the derivative was removed, dried through a cotton wool plug, and analyzed by GC / MS using the same apparatus and method as described in Example 1. For 2-methyl-3-heptanone, 6-undecanone, ethyl vinyl ketone, 5-methyl-2-hepten-4-one and 2,6-dimethyl-4-heptanone Derivatives, signals with m / e of 303, 345, 259, 301 and 317 were detected, respectively. Figure 2...

Abstract

A method of identifying a product comprises forming a tagged product by adding to said product a tracer material comprising at least one tracer compound which is acceptable for use as an additive in food and subsequently analysing a sample of said product to determine the presence of said tracer compound thereby to determine whether said sample is a sample of the tagged product. The method is especially useful for the identification of vegetable oil products from sustainably managed sources. The use of permitted food additives as tracers enables the product to be identifiedin the supply chain whilst also allowing it to be used safely in foodstuffs if required.

Description

field of invention [0001] The present invention relates to a method of marking a natural product and a method of using the marking method to identify such a product. In particular, the invention relates to a method of labeling natural products produced in a specific way or in a specific location. Background technique [0002] The introduction and availability of products produced in an economically and environmentally sustainable manner is currently very commercially advantageous. Increasing political pressure to reduce the consumption of fossil fuels has increased the production and consumption of alternative fuels, such as those produced from renewable resources, especially biodiesel. Biodiesel comprises methyl esters of long-chain fatty acids and is produced from vegetable oils (triglycerides) by transesterification with methanol. The problem with the increased consumption of biodiesel is that a large amount of land is required to grow the oily crops from which the vege...
