Using reversed phase HPLC coupled with diode array detection Fera’s food safety experts can analyse your food and drink samples, including wine, for the presence of a range of permitted artificial colours.

Artificial colourants within wine are usually frowned upon by industry, but in an effort to maintain uniform wine characteristics across a changing growing environment their use may be on the increase. Feras authenticity team are able to ensure your wine samples do not contain these colourants, and if found can accurately quantify the levels present.

Colourants are routinely used within processed foods and drinks, prompting regulators to provide legislative limits and guidance within a range of foodstuffs.

Colourants in the screen include: tartrazine (E102), quinolone yellow (E104), sunset yellow (E110) , carmoisine (E122), ponceau 4R (E124), allura red (E129), patent blue V (E131), brilliant blue (E133) , green S (E142) and indigo carmine (E132).

Fera’s flexible methods can be utilised to highlight levels of these colourants within both food and drink samples, as well as wine. Our analysis methods meet legislative limits imposed by national regulators to ensure foodstuffs remain safe for consumers and products continue to be produced as designed.

EU legislative limits are produced to ensure safe foodstuffs are offered to consumers. These limits are routinely amended and updated, encompassing new research and insights. As a result, ongoing due diligence testing activities should be utilised to ensure your foodstuffs remain compliant.

Six of the authorised food colours have specific labelling requirements which state ‘Foods containing Tartrazine (E 102), Ponceau 4 R (E 124), Sunset yellow (E 110), Carmoisine (E 122), Quinoline yellow (E 104) and Allura Red (E 129) are required to be labelled with the name or E number of the colour as they may have an adverse effect on activity and attention in children.

The list of colours permitted for use in the EU is extensive (E102 to E143) and not all are listed in the method for routine use, but additional colours can be added upon request.

Free and Total Sulphur Dioxide

While naturally present in wine, sulphur dioxide (SO2) can also be added to wine during the pre bottling stage of production to preserve products during storage. Sulphur dioxide is subject to legal limits and requires specific mention on labels where levels exceed 10 mg/L

Ash Furnace Analysis

Feras food and beverage testing capabilities can aid you in meeting regulatory requirements, especially those focused on food quality. This is because the analysis of ash after burning is a key indicator of product quality.
