This analysis is used to assess the ultimate aerobic biodegradability of materials in controlled composting conditions by the ISO 14855 standard. Testing is most typically performed on biodegradable plastics and packaging materials. Aerobic biodegradation is the process where organic materials are converted into carbon dioxide (CO2) in environments suitable for composting. The testing conditions can be tailored to simulate either industrial or domestic compost settings. It's important to note that this test specifically measures aerobic biodegradation. It does not cover chemical analyses, material disintegration, or ecotoxicity evaluations necessary for a comprehensive compostability assessment by EN 13432 and ASTM D6400 standards. However, the test is an excellent tool for comparing different product variations in the early stages of development, before conducting a full compostability assessment. The cost of the test varies based on the chosen conditions and the product, with durations ranging from 45 days to 12 months.

Determination of vitamin B7 (biotin) in food with an HPLC-UV-VIS method, or in supplements with a UPLC-MS/MS method.

Determination of elements in food, feed, and dietary supplements with ICP methods (ICP-MS, ICP-AAS, ICP-OES). Elements can contribute to the quality and properties of food and feed in several ways. Some are essential minerals that enhance nutritional value, while others (e.g., heavy metals) are considered undesirable contaminants with maximum levels set in EU food contaminant legislation. Some elements can also contribute to the sensory properties of products. Regulation (EU) No 1169/2011 allows the declaration of certain minerals if the food contains them in significant amounts in relation to daily reference intakes. The EU also keeps a database of authorized mineral additives in feed and regulates the allowed tolerances between declared amounts and analyzed amounts. Elements that are generally considered hazardous contaminants are regulated by Regulation (EU) No 2023/915 and Directive 2002/32/EC. The most common elements that are available for analysis include: Aluminium (Al), Arsenic (As), Boron (B), Cadmium (Cd), Cobalt (Co), Chromium (Cr), Iron (Fe), Manganese (Mn), Mercury (Hg), Nickel (Ni), Lead (Pb), Selenium (Se), Tin (Sn), Zinc (Zn), Molybdenum (Mb), Calcium (Ca), Phosphorus (P), Magnesium (Mg), Potassium (K), Sodium (Na), Titanium (Ti), Sulfur (S).

To ensure the traceability and safety of food and feed products, they should only be composed of and contain ingredients included in the list of ingredients. This includes not containing material originating from other plant, fungi, or animal species. The need of species verification might be relevant to: Plant-based raw materials and products (herbs, spices, fungi), Meat and meat products, Feed products based on meat. As with most cases of food adulteration, the species may be falsified to substitute expensive ingredients with less expensive ones. Non-intended ingredients may also end up in the product due to negligence or faulty production processes. Species determination is performed using PCR techniques that detect the DNA of species present in the food sample. Approaches can vary depending on the methodology: One of the most common approaches is to check whether the sample contains DNA of species that similar products are most commonly adulterated with. For example, a beef product claimed to contain only beef can be screened for the presence of pig, horse, and poultry DNA., Next-generation sequencing methods and Sanger sequencing can be applied to get more detailed information about the species present, including the relative species composition of the sample.. For a successful analysis, the sample must contain intact DNA. In highly processed food and feed items, there's a chance of the sample not containing enough intact DNA to perform analyses.

As defined in the EU honey directive 2001/110/EC, honey is the natural sweet substance produced by Apis mellifera bees from plant nectar or honeydew. Honey that is placed on the market in the EU must meet the composition criteria outlined in the directive and must not contain food additives or other additional ingredients. Honey adulteration through the addition of cheaper sugar syrups is a typical type of food fraud. In 2023, the EU’s Joint Research Centre published a technical report in which 46% of the analyzed samples showed signs of containing exogenous sugars. The declaration of botanical and geographical origin is also subject to adulteration, as honey sold under a protected designation is more valuable. Several techniques can be used for honey authenticity testing, often in combination: NMR (1H-NMR) can be used to obtain a chemical fingerprint of honey, providing information on the botanical and geographical origins, as well as possible addition of exogenous sugars., Pollen analysis with microscopy supplements NMR data on botanical and geographical origins., Stable isotope analysis (EA-IRMS) is used to determine whether honey has been extended with sugars from C4 plants, such as sugarcane or corn. It can also detect the addition of sugars from C3 plants to some extent., Methods based on liquid chromatography and high-resolution mass spectrometry (LC-HRMS) can be used to determine if honey contains exogenous oligosaccharides and, with additional precision, if honey has been extended with sugars from C3 plants, such as rice and sugar beet.. This honey authenticity testing package can be used to determine whether the sample meets the definitions and criteria set for honey in Council Directive 2001/110/EC.

Analysis of fosetyl-Al and phosphonic acid in food, feed, and dietary supplements with an HPLC-MS/MS method. The results are expressed as fosetyl-Al (sum of fosetyl, phosphonic acid, and their salts, expressed as fosetyl).

Determination of free fatty acids in fats and oils according to a titrimetric method outlined in EN ISO 660. The method can be adapted to other food samples through the addition of an extraction step, after which the acid value analysis is performed on the extracted fat or oil. The lower price of the displayed price range applies to fats and oils, while the higher one applies to samples that require extraction. There are many ways for free fatty acids to form in oils and fats. Some processing measures can increase the amount of free fatty acids, and a high water content may promote the hydrolysis of triacylglycerol, which increases the portion of free fatty acids. The general consensus is that elevated free fatty acid concentrations promote oxidation, which can be measured with parameters such as peroxide value and p-anisidine value.

Analysis of fumonisin B1 and B2 content in food, feed, and dietary supplements with an HPLC method based on the EN 14352 standard. Fumonisins are mycotoxins produced by some Fusarium species. Regulation (EU) 2023/915 sets maximum levels for the amount of fumonisins B1 and B2 in various maize products.

Analysis of free, bound, and total myo-inositol in food with an HPLC-PAD method. Inositol, or myo-inositol, plays several roles in human biology and is considered a vitamin-like compound, although not a vitamin. Regulation (EU) No 609/2013 lists inositol as a substance that can be added to products such as infant formula and baby foods. Commission Delegated Regulation (EU) 2016/127 mandates that for infant formula, the inositol content must be included in the nutrition declaration.

Determination of nivalenol content in food, feed, and supplements with an HPLC method based on EN 15791. Nivalenol is a mycotoxin produced by some Fusarium species.

Nutrient content analysis of alcoholic beverage samples, including the following parameters: Moisture, Ash, Total fat (solvent extraction following acid hydrolysis), Protein (Kjeldahl method), Sugar profile (HPLC-PAD method) including fructose, glucose, lactose, maltose, and sucrose, NaCl calculated from sodium (ICP method), Calculated carbohydrate and energy content, Alcohol content (GC-FID method). According to EU food labeling regulations, it is not currently mandatory to provide a nutrition declaration on the packaging of most alcoholic beverages sold in the EU. Nonetheless, companies are encouraged to provide the information voluntarily.

The peroxide value (PV) measures hydroperoxides formed as a result of the autoxidation of unsaturated fatty acids in food and feed products. Accumulation of autoxidation products affects sensory quality and is potentially harmful to human and animal health, making PV an important quality indicator in the food industry. Autoxidation reactions occur at different rates during the manufacturing, storage, and use of food and feed, but are generally sped up with elevated temperatures and exposure to light. This method includes an extraction step, after which the determination of peroxide value is performed on the extracted fat or oil. The method is suitable for all food and feed products that contain fat.

Determination of reducing sugar content, expressed as glucose, from food and feed with the Luff–Schoorl titration method.

Determination of starch in food with a spectrophotometric method.

Determination of polyol content in food with an HPLC-PAD method. Polyols or sugar alcohols occur naturally in foods like fruits and vegetables. Polyols are also often added to low-sugar and sugar-free products since they provide a similar sweetness to sugar without the extra calories. Also, polyols are less conducive to tooth decay or elevating blood glucose levels than sucrose. The following polyols can be determined with the method: Alpha-D-glucopyranosido-1,6-mannitol (GPM), Alpha-D-glucopyranosido-1,6-sorbitol (GPS), Maltitol, Mannitol, Sorbitol, Xylitol.

Determination of mycotoxins T-2 and HT-2 in food, feed, and dietary supplements with an HPLC method based on EN 16923. T-2 and HT-2 are mycotoxins produced by some Fusarium species. Regulation (EU) 2023/915 sets maximum levels for the amount of T-2 and HT-2 toxins in various high-risk foods, such as cereals and cereal products. Oats are particularly suspectible to high T-2/HT-2 toxin levels.

Determination of theobromine content in cocoa and cocoa products, such as chocolate, with an HPLC-UV-VIS method. Theobromine (xantheose) is the main alkaloid present in cocoa beans.

The TOTOX value gives an indication of overall oxidation in fats and oils. It is calculated using indicative values for primary oxidation products (peroxide value) and secondary oxidation products (p-Anisidine value). For TOTOX value determination, peroxide and p-Anisidine analyses are performed and their results are reported along with the total oxidation value. Testing is suitable for animal and vegetable fats and oils, fatty acids, and their mixtures. Milk fats and lecithin cannot be analyzed.

We offer a range of liquid chromatography-based methods to determine the vitamin content of food and dietary supplement samples. Examples of target analytes include: Vitamin A (retinol, beta-carotene), Vitamin B1 (thiamine), Vitamin B2 (riboflavin), Vitamin B3 (niacin), Vitamin B5 (pantothenic acid), Vitamin B6 (pyridoxine), Vitamin B7 (biotin), Vitamin B9 (folic acid), Vitamin B12 (cyanocobalamin), Vitamin C (ascorbic acid), Vitamin D3 (cholecalciferol), Vitamin E (alpha-tocopherol, alpha-tocopheryl acetate), Vitamin K1 (phylloquinone), Vitamin K2 (menaquinone-4, menaquinone-7). According to EU regulations, the concentration of a vitamin can only be declared on the packaging if it is present in the food or supplement in significant amounts. For beverages, this means a minimum of 7.5% of the daily reference intake (DRI) per 100 ml of the product. For other products, the minimum concentration is 15% of DRI per 100 g. Vitamin content analysis is the recommended way to verify that the declared level is accurate, especially when a food or supplement is marketed with vitamin-related health claims. The displayed price range applies to the analysis of one vitamin in one sample. Package deals are available to determine several vitamins simultaneously and to analyze multiple samples. Please ask our experts for an offer.
