Determination of allergens from food, feed, or supplement samples with enzyme-linked immunosorbent assay (ELISA). The following allergens are available for analysis: Peanut, Soy protein, Gliadin/gluten, Casein, Cashew, Egg white, Fish, Hazelnut, Crustaceans, Lupin, Almond, Milk protein, Mollusks, Pistachio, Mustard seed protein, Sesame, ß-Lactoglobulin, Whole egg, Walnut protein. The cost is per allergen per sample. According to EU food labeling requirements, it is mandatory to display allergen information on packaged foods.

Determination of caffeine from food and dietary supplements with an HPLC-UV-VIS method. According to Regulation (EU) No 1169/2011 on the provision of food information to consumers, caffeine-containing products must be labeled with the following disclaimers: "High caffeine content. Not recommended for children or pregnant or breast-feeding women". The label applies to beverages other than tea or coffee that contain more than 150 mg/l of caffeine., "Contains caffeine. Not recommended for children or pregnant women". The label applies to food and supplements where caffeine is added for a physiological purpose.. The caffeine content of applicable products needs to be expressed on the label in mg per 100 g/ml, or per portion in the case of supplements.

Determination of volume-specific surface area (VSSA) for the identification of nanoparticles. VSSA can be calculated from the specific surface area obtained by N2 adsorption and the BET method, and the effective density obtained by He Pycnometry. The measurement is a part of the EC recommendation for the definition of nanomaterials (2022/C229/01). According to the recommendation, materials with a VSSA of < 6 m2/cm3 are not considered nanomaterials.

UPLC-MS/MS analysis for determining the melatonin content in dietary supplements. According to Regulation (EU) No 432/2012, melatonin supplements may be marketed with the following health claims: "Melatonin contributes to the alleviation of subjective feelings of jet lag." The claim can be used if the product contains at least 0.5 mg of melatonin per portion., "Melatonin contributes to the reduction of time taken to fall asleep." The claim can be used if the product contains at least 1 mg of melatonin per portion..

Determination of starch in food with a spectrophotometric method.

This analysis package is used to determine the amount of polycyclic aromatic hydrocarbons in food, feed, and dietary supplements. The package covers the following substances, known together as PAH 4: benzo(a)pyrene, benz(a)anthracene, benzo(b)fluoranthene, chrysene. According to EU regulations, materials that potentially require PAH testing include: foods and dietary items intended for infants or young children, oils and fats, smoked meat and fish, smoked products prepared using traditional methods, smoke flavorings. Compliance can be evaluated against the maximum levels set in Regulation (EU) 2023/915 on food contaminants and Regulation (EC) No 2065/2003 on smoke flavorings.

Determination of microplastics present in food samples using Raman or FTIR microspectroscopy. The analysis report will specify different types of polymers by size (1-50 µm, 50–100 µm, 100–500 µm, >500 µm).

Determination of vitamin B7 (biotin) in food with an HPLC-UV-VIS method, or in supplements with a UPLC-MS/MS method. According to Regulation (EU) No 1169/2011, the biotin content of food products may be included in the nutrition declaration if it is present in significant amounts. The daily reference intake for biotin is 50 µg, and biotin content can be declared if the product contains at least: 7.5 µg/100 g or 100 ml in products other than beverages (15% of reference intake), 3.75 µg/100 ml in beverages (7.5% of reference intake), 7.5 µg per portion if the package contains a single portion (15% of reference intake). Foods that contain at least the above amounts of biotin can be labeled with the nutrition claim "Source of biotin." Additional nutrition and health claims related to vitamin B7 can be applied in accordance with Regulations (EC) No 1924/2006 and (EU) No 432/2012.

Determination of patulin content in food, feed, and dietary supplements with an HPLC method based on EN 14177. Patulin is a mycotoxin produced by several different species of fungi. Apples and apple products are especially susceptible to patulin contamination, but the toxin can also be found in other foods. Regulation (EU) 2023/915 sets maximum levels for patulin in various high-risk products, such as juices, apple products, and baby food. The EU has also addressed the means to reduce and prevent patulin contamination in apple juices and apple juice-based beverage ingredients in a Commission Recommendation from 11 August 2003.
