Falsification beeswax Parameters (quantitative): paraffin wax [g/100 g], stearic acid [g/100 g] Article Number: 2011018 Description: Recently, there was an enhanced level of falsification of beeswax with paraffin wax and stearin in the international trade. This can influence the development of bees negatively and embedded honey can be contaminated. Therefore, it is important to be able to determine the quality of beeswax. Category: chemical-physical testing food and feed honey and beeswax Accreditation: This proficiency test is not included in the scope of the accreditation. |

Falsification honey Parameters (qualitative): Identification of rice syrup, Identification of sugar beet syrup Article Number: 2011014 Description: Recently, there was a dramatic increase of falsification in the international honey trade, i.a. the honey is often mixed with industrial sugar syrup. With this proficiency testing the comparability of detecting sugar syrup in honey can be determined. Category: chemical-physical testing food and feed honey and beeswax Accreditation: This proficiency test is within the scope of the A2LA and the DAkkS accreditation. |

Honey 1 Parameters (quantitative): diastase number acc. to Schade [-], proline [mg/kg], hydroxymethylfurfural (CAS 67-47-0) [mg/kg], electrical conductivity [mS/cm], moisture [g/100 g], glycerin [mg/kg], ethanol (CAS 64-17-5) [mg/kg], pH value [-] Article Number: 2010455 Description: With this proficiency testing the comparability of the chemical-physical testing of different attributes in honey can be assessed. The diastase activity serves to evaluate the grade of heating treatment. The amount of proline provides information about the ripeness and the natural purity. Hydroxymethylfurfural (HMF) develops during sugar degradation during prolonged storage and through high storage temperatures. The conductivity helps to evaluate the purity of sort honey, the pH-value and the water content are general quality markers, while increased glycerin and ethanol amounts indicate alcoholic fermentation. Category: chemical-physical testing food and feed honey and beeswax Accreditation: This proficiency test is within the scope of the A2LA and the DAkkS accreditation. |

Honey 2 Parameters (quantitative): glucose (anhydrous) [g/100 g], fructose (anhydrous) [g/100 g], maltose (anhydrous) [g/100 g], sucrose (anhydrous) [g/100 g], turanose (anhydrous) [g/100 g], saccharase activity acc. to Siegenthaler [U/kg], saccharase activity acc. to Hadorn [-], free acidity [mmol/kg], ash [g/100 g] Article Number: 2010708 Description: With this proficiency testing the comparability of the chemical-physical testing of different attributes in honey can be assessed. The composition and the amount of sugars helps to evaluate the honey quality and the source of honey yield. The saccharase number is a measure for the saccharase activity and serves to evaluate the grade of heating treatment. Category: chemical-physical testing food and feed honey and beeswax Accreditation: This proficiency test is within the scope of the A2LA and the DAkkS accreditation. |

Pesticide residues in honey Parameters (quantitative): τ-fluvalinate (CAS 102851-06-9) [µg/kg], DEET (CAS 134-62-3) [µg/kg], piperonylbutoxide (CAS 51-03-6) [µg/kg], malathion (CAS 121-75-5) [µg/kg], chlorpyrifos (CAS 2921-88-2) [µg/kg] Article Number: 2011004 Description: Bees pollenize about 80% of agricultural crops, which are treated with different pesticides. Consistently, pesticide residues are found in honey. The honey however may only be sold if certain prescriptive limits are not exceeded. The proficiency test design includes at least 2 samples in different concentration ranges: this allows participants to demonstrate their ability to ensure the accuracy of results even in different concentration ranges and, at the same time, fulfills an important part of the requirements for method validation according to SANTE 11312/2021. Category: chemical-physical testing food and feed honey and beeswax Accreditation: This proficiency test is within the scope of the A2LA and the DAkkS accreditation. |

Pyrrolizidine alkaloids in honey Parameters (quantitative): Screening for at least 9 different pyrrolizidine alkaloids, e.g. monocrotaline, heliotrine, retrorsine Article Number: 2011006 Description: Honey is one of the major sources for consuming toxic pyrrolizidine alkaloids (PA). PA are present in over 6000 plant species and function as protecting agents against predators. PA are liver-damaging and most likely carcinogen. Therefore, honey with high PA levels should not be sold. Category: chemical-physical testing food and feed honey and beeswax Accreditation: This proficiency test is within the scope of the A2LA and the DAkkS accreditation. |

Relative frequency of pollen in honey Parameters (quantitative): Relative pollen frequency [%] Article Number: 2011012 Description: The accuracy of the declaration of the regional and botanical honey origin can be determined microscopically by checking the relative frequency of pollen. With this proficiency testing the comparability of this method can be tested. Category: chemical-physical testing food and feed honey and beeswax Accreditation: This proficiency test is within the scope of the A2LA accreditation. |
