Test Description

This proficiency test evaluates your testing ability for Nitrate in carrot purée. Carrots are a well-known root vegetable that enjoy large amounts of consumption across the globe.  Carrot matrix is now provided in addition to the existing green leafy vegetable matrices.

Nitrate and nitrite mostly derive from fertilisers used in agriculture and are used as food preservatives.  They are often detected in contaminated drinking water, cured meat products as well as fruits and vegetables. Exposure at high levels can result in severe health issues. Regulatory limits exist for nitrate and nitrite in a variety of food products in the EU and elsewhere.

Nitrates are a valuable chemical within grown foods such as a range of vegetables. It has an important role to play when preserving foodstuffs as well as improving flavour in certain foods. However, high, sustained levels of nitrates in human diets can cause negative effects and lead to potentially harmful consequences.

To maintain the high quality testing needed to identify accurately these potentially unsafe levels, well-designed quality assurance processes should be put into practice. Fapas proficiency tests can form the benchmark for these processes, by providing directly comparable results from which to highlight any flaws in your testing process from which areas of bias may occur. This direct comparison is only achieved through the use of real food test materials, which share the same characteristics as your laboratories routine testing samples.
