This document specifies a test method for the determination of the transfer of antimicrobial constituents from paper and board materials and articles intended for food contact. NOTE The use of this document is determined by legislation pertaining to paper and board intended to come into contact with foodstuffs.
This document specifies a simulating method of test for determination of the release of metal-ions from enamelled articles, which are intended to come into contact with food. This document also specifies limits for the release of metal-ions from enamelled articles, which are intended to come into contact with food. This document is applicable to enamelled articles, including tanks and vessels, which are intended to be used for the preparation, cooking, serving and storage of food.
This document describes the procedure to qualitatively detect genetically modified organisms (GMOs) and derived products by analysing the nucleic acids extracted from the sample under study. The main focus is on polymerase chain reaction (PCR) based amplification methods.
It gives general requirements for the specific detection and identification of target nucleic acid sequences (DNA) and for the confirmation of the identity of the amplified DNA sequence.
Guidelines, minimum requirements and performance criteria laid down in this document are intended to ensure that comparable, accurate and reproducible results are obtained in different laboratories.
This document has been established for food matrices, but could also be applied to other matrices (e.g. feed and plant samples from the environment).
Specific examples of methods are provided in ISO/TS 21569 part 11 and the other parts of this series.
This part of ISO 16634 specifies a method for the determination of the total nitrogen content and the calculation of the crude protein content of cereals, pulses and cereal coproducts (e.g. wheat flour, wheat starch, peas proteins, wheat gluten, semolina). This method, like the Kjeldahl method (see References [1] and [6]), does not distinguish between protein nitrogen and non-protein nitrogen. For the calculation of the protein content, various conversion factors are used (see 3.2).
