Slurry mixing: recipe for reliable results

February 2024

In the dynamic landscape of food and feed
analysis, ensuring the uninterrupted flow of
production is a constant challenge for the food
industry. Contaminants, often unevenly distributed within batches, present a risk to production continuity.

Challenges in mineral oil analysis

October 2023

Mineral oil hydrocarbons (MOH) are a complex mixture of hydrocarbons, which are chemical compounds of different sizes and structures. MOH are mainly derived from crude oil.
The group of MOH comprises both ‘aromatic’ hydrocarbons (MOAH) and ‘saturated’ hydrocarbons (MOSH).

Nicotine on food: clearing the smoke

September 2023

Nicotine is the main alkaloid in tobacco and other tobacco species; it is also found in low concentrations in other crops belonging to the family of Solanaceae. Due to its insecticidal capacity, the compound was used as an active substance in
plant protection products in the past.

Dithiocarbamates

August 2023

Dithiocarbamates (DTCs) are a group of organosulfur fungicides, widely used for decades to control hundreds of fungal pathogens in a variety of crops. DTCs are very instable and therefore metabolise quickly to carbon disulfide (CS2). This causes two important challenges: (i) naturally occurring CS2 in certain crops can generate false positive results and (ii) the analytical distinction of the different DTCs is very challenging.

Pyrrolizidine Alkaloids: A Wolf in Sheep's Clothing

July 2023

Pyrrolizidine alkaloids (PAs) are naturally occurring compounds
which are mainly produced as secondary metabolites by plants to ward off predators (herbivores) but are also produced by certain fungi and bacteria.

Acrylamide - heated with a twist

May 2023

Some foods, such as potatoes, are heated in order to obtain a certain, desired, flavour and aroma. However, during this heating (>120°C) also acrylamide can be formed, in a process known as the Maillard reaction.

Harmonised action limits for MOAH in food

November 2022

Mineral oil hydrocarbons (MOH) are a complex mixture of hydrocarbons, which are chemical compounds of different sizes and structures. MOH can be present on food as a contaminant, resulting from for example pollution, food processing or packaging.

MCPD analysis in oils and fats

February 2023

During the processing (refining) of edible vegetable oils and fats, some process contaminants are formed, including 2-monochloropropane-1,2-diol (2-MCPD), 3-monochloropropane,-1,2-diol (3-MCPD) and its related fat soluble forms (also known as 3-MCPD esters), and glycidyl esters (GE).

Alternative sources for pesticides

February 2023

Positive findings of active ingredients of pesticide products in food and feed samples can certainly not always be attributed to deliberate use. This can lead to disagreements between different parties of the food industry as well as between laboratories and their clients.

Succesvolle relana audit

Primoris maakt deel uit van relana®, de kwaliteitscirkel van een tiental Europese labo's op het vlak van analyse van pesticiden en contaminanten. Eerder dit jaar was er een relana audit in Primoris en hierbij kregen we uitstekende feedback. In de eerste plaats staat het labo op een hoog en stabiel kwaliteitsniveau en daarnaast waren de auditoren ook onder de indruk van de bekwaamheid van onze mensen.

Acrylamide - methode update

Dankzij de inspanningen van ons in-house R&D team kunnen we nu de analyse van acrylamide aanbieden met een drastisch lagere doorlooptijd en kunnen we de huidige rapporteerlimiet verlagen naar 20 ppb.

Wetgeving | Anorganisch arseen in granen, rijst en babyvoeding

Op 06/03/2023 publiceerde de Europese Commissie hun verordening 2023/0465 omtrent de maximumgehalten aan anorganisch arseen in bepaalde levensmiddelen.

Maleïne hydrazide via LC-MS/MS

Vanaf nu analyseren we maleïne hydrazide (MH) met LC-MS/MS en niet langer met UV, met snellere en meer precieze resultaten als gevolg.
