Bendrieji molekulinių biologinių žymenų analizės metodai. Analizės metodai genetiškai modifikuotiems organizmams ir jų produktams aptikti. 1 dalis. Kokybiniai nukleorūgščių nustatymu paremti metodai (ISO/DIS 21569-1:2025)

This International Standard 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 International Standard are intended to ensure that comparable, accurate and reproducible results are obtained in different laboratories. This International Standard 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 Annexes A to D.

Pienas, pieno produktai, mišiniai kūdikiams ir suaugusiesiems. Riebalų rūgščių sudėties nustatymas. Kapiliarinės dujų chromatografijos metodas (ISO/FDIS 16958:2025)

ISO 16958:2015 specifies a method for the quantification of individual and/or all fatty acids in the profile of milk, milk products, infant formula and adult nutritional formula, containing milk fat and/or vegetable oils, supplemented or not supplemented with oils rich in long chain polyunsaturated fatty acids (LC-PUFA). This also includes groups of fatty acids often labelled [i.e. trans fatty acids (TFA), saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), omega-3, omega-6 and omega-9 fatty acids] and/or individual fatty acids [i.e. linoleic acid (LA), α-linolenic acid (ALA), arachidonic acid (ARA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)]. The determination is performed by direct transesterification in food matrices, without prior fat extraction, and consequently it is applicable to liquid samples or reconstituted powder samples with water having total fat ≥ 1,5 % m/m. The fat extracted from products containing less than 1,5 % m/m fat can be analysed with the same method after a preliminary fat extraction using methods referenced in Clause 2. Dairy products, like soft or hard cheeses with acidity level ≤ 1 mmol/100 g of fat, can be analysed after a preliminary fat extraction using methods referenced in Clause 2. For products supplemented or enriched with PUFA with fish oil or algae origins, the evaporation of solvents should be performed at the lowest possible temperature (e.g. max. 40 °C) to recover these sensitive fatty acids.

This document defines terms, establishes manufacturing, safety and functional requirements and corresponding tests, and specifies data for marking, labelling and instructions for use, for pressure cookers. This document is applicable to portable pressure cookers for domestic use, with gross volume up to 25 l, with control pressure over 4 kPa and less than 150 kPa, with either integrated or independent heating (e.g. gas burner, electrical plate, induction hobs, ceramic hobs). NOTE All pressures mentioned in this text are related to atmospheric pressure.
