Foodstuffs - Determination of cyclamate - High performance liquid chromatographic method

This draft European Standard specifies a high performance liquid chromatographic (HPLC) method for the determination of sodium cyclamate in foodstuffs (1), (2), (3). The method has been validated in an inter-laboratory test according to ISO 5725:1986 (4) which has been carried out with lemonade, orange juice beverage, fruit yogurt and spray cream. In the addition to the matrices investigated in the inter-laboratory test, experiences have shown that the method is also applicable to various foodstuffs, such as gherkins, canned morello cherries, pineapple, orange nectar, apricot jam, ...

Foodstuffs - Minimum performance requirements for quantitative measurement of the food allergens milk, egg, peanut, hazelnut, almond, walnut, cashew, pecan nut, brazil nut, pistachio nut, macadamia nut, wheat, lupine, sesame, mustard, soy, celery, fish, molluscs and crustaceans
SIST EN 17855:2024

This document specifies minimum performance requirements for methods that quantify the food allergens milk, egg, peanut, hazelnut, almond, brazil nut, macadamia nut, cashew, pistachio nut, walnut, pecan nut, lupine, sesame, mustard, soy, celery, fish, molluscs, crustaceans, and wheat in raw and processed foodstuffs. Within the scope of this document, minimum requirements for an LOQ (Limit of Quantification) will be derived from threshold data of allergic consumers. For quantitative antibody-based methods, a normative annex will describe what specific information the method developer needs to deliver and how performance characteristics shall be validated. Regarding PCR and LC-MS/MS, information on performance characteristics are in parts covered by EN 15634-1 and EN 17644. This document does not apply to fragmented or hydrolysed food allergens, such as casein hydrolysates or soy sauce. It also does not apply to methods that deliver qualitative results only. Methods that cover gluten-containing cereals (wheat, rye, and barley) with regard to coeliac disease are covered by EN 17254.

Foodstuffs - Multimethod for the determination of aflatoxins, deoxynivalenol, fumonisins, ochratoxin A, T-2 toxin, HT-2 toxin and zearalenone by LC-MS/MS
SIST EN 17641:2022

This document describes a method using isotopically labelled standards for the quantitative determination of aflatoxins B1, B2, G1, G2 and M1 (AFB1, AFB2, AFG1, AFG2 and AFM1), ochratoxin A (OTA), deoxynivalenol (DON), zearalenone (ZEN), T-2 and HT-2 toxins (T-2 and HT-2) and fumonisins B1 and B2 (FB1 and FB2) in foods by liquid chromatography (LC) coupled with tandem mass spectrometry (MS/MS).
A specific immunoaffinity column (IAC) clean-up is needed for aflatoxins (AFs) and OTA in food intended for infants and young children (e.g. infant cereals, milk-based powders), in spices, in dried fruits and in nuts.
The method has been validated through an intercollaborative study on different commodity groups: cereals and cereal-based products including food for infant and young children, nuts, spices, dried fruits and milk powder. The measuring range of each mycotoxin in these naturally contaminated and/or spiked food samples were:
- AFB1: 0,085 7 µg/kg - 11,4 µg/kg;
- AFB2: 0,079 2 µg/kg - 12,5 µg/kg;
- AFG1: 0,062 8 µg/kg - 20,9 µg/kg;
- AFG2: 0,052 0 µg/kg - 15,0 µg/kg;
- AFM1: 0,034 2 µg/kg - 0,110 µg/kg;
- OTA: 0,448 µg/kg - 17,2 µg/kg;
- DON: 45,2 µg/kg - 743 µg/kg;
- ZEN: 9,57 µg/kg - 131 µg/kg;
- T-2: 10,3 µg/kg - 57,9 µg/kg;
- HT-2: 9,50 µg/kg - 81,8 µg/kg;
- FB1: 31,1 µg/kg - 4 260 µg/kg;
- FB2: 44,2 µg/kg - 1 300 µg/kg.
The measuring ranges of the method for each mycotoxin/matrix combination are given in Table 8.

Foodstuff - Detection of irradiated foodstuff containing cellulose by ESR spectroscopy
SIST EN 1787:2022

This document specifies a method for the detection of foodstuff containing cellulose which have been treated with ionizing radiation, by analysing the electron spin resonance (ESR) spectrum, also called electron paramagnetic resonance (EPR) spectrum, of the foodstuff, see [1] to [13].
Interlaboratory studies have been successfully carried out with pistachio nut shells, [14] to [18], paprika powder [19] and [20] and fresh strawberries [21]. However, it has been shown that chemical bleaching of nuts in shells can lead to comparable signals. For further information, see Clause 8 on limitations.

SIST-TS CEN/TS 17329-1:2021

This document describes the performance characteristics and minimum performance criteria for conducting a single-laboratory validation study for qualitative (binary) real-time polymerase chain reaction (PCR) methods applied for the detection of specific DNA sequences present in foods.
The protocol was developed for qualitative real-time PCR methods for the detection of DNA sequences derived from genetically modified foodstuffs. It is applicable also for single-laboratory validation of qualitative PCR methods used for analysis of other food materials, e.g. for species detection and identification.
The document does not cover the evaluation of the applicability and the practicability with respect to the specific scope of the PCR method.
