BMF 99 - MCPD and glycidyl fatty acid esters

There has been a growing interest in the analysis of food for 3-monochloropropanediol (3-MCPD) and glycidyl fatty acid esters in recent years. These fatty acid ester artefacts are formed during production and heating of oils and fats, and are thought to be harmful when consumed at a high level. Consequently, they are a great concern to health authorities, fuelling a demand for analytical methods to monitor levels in foods, accompanied by appropriate regulation.

BMF 73 - Sunscreen agents

Sunscreen is a common body care product that many people use to protect themselves from the adverse effects of the sun. If used as instructed, sunscreen can prevent premature ageing, skin damage, and decrease your risk of developing skin cancer. However, some chemical components of sunscreens have come under the spotlight due their adverse effects on health and the environment.

BMF 82- Triclosan

Triclosan (5-Chloro-2-(2,4-dichlorophenoxy)phenol; Cat. No. 8472.12) is an antimicrobial agent extensively used in soaps, shampoos, deodorants, toothpaste etc. and the content typically varies from 0.1-1%.

Triclosan is a white crystalline substance with structural similarities to dibenzo-p-dioxins and dibenzofurans. Its mechanisms of action, risk of bacterial resistance and its possible role in disruption of hormonal development has been controversial.

Our interest in triclosan increased following purification of a commercial sample by repeated crystallizations, which yielded the PCDF 2,4,8-trichlorodibenzofuran (Cat. No. 11789.12) rather than triclosan itself.

BMF 76- Drinking Water Quality

Clean and safe drinking water is essential for life! Therefore water quality, as well as taste and odour, are highly regulated and monitored. It is also a matter of public trust in your local drinking water.Off-flavours of drinking water are often taints of either products from microorganisms or from food products.Some algae, particularly blue-green algae (cyanobacteria) such as Anabaena, produce 2-methylisoborneol (MIB) together with other odourous chemicals such as geosmin. These two compounds typically affect the flavour of drinking water or fish living in that water.Geosmin has a distinct earthy flavour and taste, while 2-methylisoborneol (MIB) gives a musty and earthy flavour to water and is often associated with algal blooms. MIB is also a factor in cork-taint in wine-making.

BMF 32 - Plasticizers: Phthalates and Adipates

Phthalate and adipate esters are widely used as surfactants and in food and personal care products as plasticizers. Phthalates and adipates are also found in food as a result of leakage into food containers. Chiron offers a wide range of analytically pure deuterated and native phthalates and adipates, as well as mixes. Custom made mixes are available on request.

BMF 48 - Melamine-15N3

Melamine is a trimer of cyanamide with a 1,3,5-triazine skeleton. It contains 66% nitrogen by mass and, if mixed with resins, has fire retardant properties due to release of nitrogen. It is most commonly encountered as melamine resin in combination with formaldehyde, which is a very durable thermosetting plastic used among other things for dinnerware, countertops and cooking spoons.

 

Melamine has been added to low quality pet food and infant formula to make the protein content appear higher than it actually is. Simple protein tests uses nitrogen content as a measure for proteins, and addition of protein-rich compounds like melamine therefore alters the results.

 

Chiron AS offers both native and 15N-labelled melamine for analytical work, as well as the related metabolites like ammeline and ammedine.

BMF 50 - Mixed phthalates

Certain phthalates are listed on the CANDIDATE LIST OF SUBSTANCES OF VERY HIGH CONCERNFOR AUTHORIZATION by ECHA, the European Chemicals Agency:

 

Dibutyl phthalate
Diisobutyl phthalate
Benzyl butyl phthalate
Bis(2-ethylhexyl) phthalate
Bis(2-methoxyethyl)phthalate

 

UNIQUE in-house proprietary technology enables Chiron to offer pure mixed phthalate-esters in sufficient quantities for toxicological and analytical purposes. In contrary to traditional synthesis methods were transesterification is a problem, the new method enables us to synthesize these esters is pure separated isomeric forms.

BMF 55 - Nitrosamines and Nitramines

It is well known that nitrosamines and nitramines can be dangerous to human health, animals and plant lives. There are several technologies which release them into the environment.

 

Nitrosamines are a class of chemical compounds that have received much attention since 1956, when two British scientists, John Barnes and Peter Magee, reported that dimethylnitrosamine produced liver tumors in rats. Nitrosamines are formed by reactions of nitrites and secondary amines (e.g. in proteins) under acidic conditions like gastric milieus. Human beings ingest nitrites from food, esp. fried or grilled meat and vegetables. Disposal of tobacco products also causes a high intake of nitrosamines (mainly N-Nitrosonornicotin).

High quality Standards for Food Safety

In recent years, there has been increasing interest in 3-MCPD fatty acid esters in food analysis. These esters are formed
during the production and heating of oils and fats. They are considered harmful at high levels of consumption.
3-MCPD is a known carcinogen found as a heat-induced contaminant in many different types of fat-containing
foodstuffs. The European Food Safety Authority (EFSA) has defined a limit of 2μg/kg body weight as a tolerable daily
intake (TDI).
