37 Food & Beverage Analysis Determining Antibiotic Residues in Foodstuffs


Genevac has published a customer report that describes an evaporative sample preparation protocol for highly sensitive analytical methods used to test foodstuffs, principally meat, fish and shellfish, for the presence of antibiotics.


The analytical method calls for good upstream sample preparation to eliminate the effects of the matrix, and can be manual and time consuming, particularly where evaporation is concerned.


The authors describe how the installation of the Genevac EZ-2 evaporator in their laboratory is estimated to save the laboratory 2-3 hours per day that previously was spent on evaporation tasks. The evaporator has also enabled the processing of larger sample series within a given day and significantly reduced the contamination (carry-over) issue.


Accurate analytical results are critical to ensure the quality and safety of food and beverages. To ensure accurate repeatable results careful sample preparation is critical, especially when the analyte of interest is volatile. Genevac evaporator systems are proven in a growing number of food and beverage applications, from testing constituents of beverages such as Cognac or gluten levels in Whisky, determining pesticide levels in fruit and vegetables to analysing for antibiotic residues in meats or vitamin levels in cereals.

Velp Scientifica presents the NDA Series Dumas Nitrogen/Protein Analyser, consisting in two extremely advanced models aimed to simplify routine operation and reduce operating costs to the minimum. Choose between NDA 701 and NDA 702, a unique dual carrier gas nitrogen and protein analyser.


Both the units use high-technology to optimise productivity. With the highest limits of detection and readability on the market and an RSD lower than 0.5% for EDTA, the user is assured of high precision results. Samples can be loaded in nearly 120 positions, using the same loading procedure whether solid, paste or liquid. Once loaded, the unit runs fully automatically offering exceptional reproducibility and comparability of results. The lowest detection limit of the market ensured, only 0.001 mg/N.


With the new NDA 702 Dual Carrier Gas Dumas N/Protein Analyser, Velp Scientifica takes a further step in enhancing accuracy and end user flexibility. Helium has been the carrier gas for elemental analysis for many years, whilst industry was demanding an alternative carrier gas to address application needs, availability and cost effectiveness. The Velp NDA 702 fulfils the industry’s needs by offering the optimum alternative carrier gas, Argon, which can be utilised seamlessly alongside Helium.


Switching from Helium to Argon or vice-versa with the Velp NDA 702 is truly quick, easy and safe: simply choose the gas, close one tap and open the other. No need to replace parts or upgrade software.


With the Velp NDA 702 absolute flexibility becomes the standard.


No need to decide in advance which carrier gas to use and exciting new features including the completely re-designed DUMASoft™ offering multi- lingual support, results at a glance without the need to create a report, or to name calibration curves. All of this together with the exclusive Velp TEMS™ technology for conspicuous savings in terms of Time, Energy, Money and Space and an unmatched new levels of LOD and accuracy that state an industry record.


Velp Scientifica NDA Series complies with all standards in the food and feed markets – AOAC, AACC, ASBC, OIV and ISO – making it the ideal choice for industrial and monitoring laboratories. 35355pr@reply-direct.com


Straightforward Determination of Iodine Value in Fats and Oils Using Thermometric Titration


Iodine value (IV) is a measure of the total number of double bonds present in fats and oils. It is expressed as the ‘number of grams of iodine that will react with the double bonds in 100 grams of fats or oils’. The determination is conducted by dissolving a weighed sample in a non-polar solvent such as cyclohexane, then adding glacial acetic acid. Metrohm Application Note AN-H-076 describes the procedure.


The double bonds are reacted with an excess of a solution of iodine monochloride in glacial acetic acid (‘Wijs solution’). Mercuric ions are added to hasten the reaction. After completion of the reaction, the excess iodine monochloride is decomposed to iodine by the addition of aqueous potassium iodide solution, which is then titrated with standard sodium thiosulfate solution.


The titration procedure eliminates operator involvement in the determination. The Wijs’ solution is added, with a 300 seconds (5 minutes) wait programmed before 10 mL of 15% KI solution is added. The titration commences automatically.


Thermometric titration has been successfully used to analyse foods ranging from dairy products, instant noodles, cheese, canned fish, dry snack food, sauces, soups, and more.

New Reference Standards for Accurate trans Fat Determination


Growing concern about the impact of partially hydrogenated oils on human heart health makes accurate data on trans fat content in foods critical for protecting consumers. New reference standards from Restek help you ensure that your lab is generating accurate results. In addition to a derivatisation agent, Restek also offer internal and calibration standards of verified composition and stability. Paired with an Rt-2560 GC column, these new reference standards help ensure accurate determination of trans fat content in foods and edible oils, and they are suitable for AOAC and AOCS methods.
