12 December 2018 | By Shimadzu
Mineral oil residues in food gain a lot of public concern in there recent years. No matter if talking about rice, noodles, olive oil or chocolate, there are numerous examples of mineral oil contaminations in food.
Determination of 208 pesticide residues and their metabolites in foods using Oasis PRiME HLB and Xevo TQ-GC
10 December 2018 | By Waters
Gas chromatography-mass spectrometry (GC-MS) has been a common analytical method for pesticide measurement due to its high efficiency of separation, along with its qualitative and quantitative performance.

The flavour and aroma of food and beverages is key for perception and acceptance by the consumer. Gas Chromatography with Mass Spec detection is an effective tool to determine most of the key compounds involved and is finding increased adoption in recent years due to new techniques in sampling the…
Analysis of aroma compounds in edible oils by direct Thermal Desorption GC/MS using slitted microvials
9 July 2018 | By GERSTEL
The determination of aroma compounds in edible oils (olive oil, sunflower oil, fish oil etc.) is important for manufacturers and vendors of these products. Especially off-flavors / off-flavours derived from unsaturated fatty acid degradation such as, for example, hexanal, 2-(E)-nonenal and 2,4-(E,E)-decadienal are of interest. These compounds can compromise the…
Fully automated determination of 3-MCPD and Glycidol in edible oils by GC/MS based on the commonly used methods ISO 18363-1, AOCS Cd 29c-13, and DGF C-VI 18 (10)
9 July 2018 | By GERSTEL
3-MCPD and Glycidol and especially their fatty acid esters are process contaminants that are formed, for example, when edible oils and fats are refined. At least some of the above-mentioned substances are classified as potential human carcinogens, a fact which has prompted the introduction of rules and regulations that specify…

Determination of Anionic Polar Pesticides in Spinach Using a Novel Application of Torus DEA Column Chemistry by Liquid Chromatography-Tandem Quadrupole Mass Spectrometry
13 June 2018 | By Waters
Pesticide residues resulting from the use of plant protection products on crops that are used for food or feed production may pose a risk factor for public health.
25 May 2018 | By Agilent Technologies
Refining raw food oil is essential to ensure safety and palatability. Unfortunately, it can be the origin of MCPD and glycidyl fatty esters, which can have harmful carcinogenic and mutagenic effects. The European Food Safety Authority (EFSA) indicates a risk associated with free 3-MCPD and Glycidol being available in the…

About this webinar Routine testing laboratories continue to strive for efficient and reliable sample throughput. Multiresidue pesticides is an example of this, where the generic extraction offered by QuEChERS has streamlined sample preparation. However, for comprehensive pesticide testing, both liquid and gas chromatography are typically required. During this webinar, Waters…
