ISO 1735 | IDF 5: 2004 – Cheese and processed cheese products – Determination of fat content – Gravimetric method (Reference method)
This standard specifies the reference method for the determination of the fat content of all types of cheese and processed cheese products having lactose contents of below 5 % (mass fraction) of non-fat solids. This standard has been replaced by ISO 23319 | IDF 250: 2022
ISO 8968-4 I IDF 20-4: 2016 – Milk and milk products – Determination of nitrogen content – Part 4: Determination of protein and non-protein nitrogen content and true protein content calculation (Reference method)
This part of ISO 8968 | IDF 20 specifies a method for the direct and indirect determination of the protein nitrogen content of liquid, whole or skimmed milk.
ISO 8968-3 | IDF 20-3: 2004 – Milk – Determination of nitrogen content – Part 3: Block-digestion method (Semi-micro rapid routine method)
This standard specifies a method for the determination of the nitrogen content of liquid, whole or skimmed milk. It concerns a semi-micro rapid routine method following the block-digestion principle.
ISO 8968-5 | IDF 20-5: 2001 – Milk – Determination of nitrogen content – Part 5: Determination of protein-nitrogen content
This standard has been withdrawn and replaced by the joint standard ISO 8968-4 I IDF 20-4: 2016.
ISO 5534 | IDF 4: 2004 – Cheese and processed cheese – Determination of the total solids content (Reference Method)
This standard specifies the reference method for the determination of the total solids content of cheese and processed cheese
ISO 1211 | IDF 1: 2010 – Milk – Determination of fat content – Gravimetric method (Reference method)
This standard specifies the reference method for the determination of the fat content of milk of good physicochemical quality. The method is applicable to raw cow milk, raw sheep milk, raw goat milk, reduced fat milk, skimmed milk, chemically preserved milk, and processed liquid milk. It is not applicable when greater accuracy is required for […]
ISO 14673-3 | IDF 189-3: 2004 – Milk and milk products – Determination of nitrate and nitrite – Part 3: Method using cadmium reduction and flow injection analysis with in-line dialysis (Routine method) – Second Edition
This standard specifies a routine method for the determination of the nitrate and nitrite contents of milk and milk products by cadmium reduction and flow injection analysis (FIA). The method is applicable to hard, semi-hard and soft cheeses of various ages, and processed cheese. The detection limits of the method are 0,5 mg of nitrate […]
ISO 14675 | IDF 186: 2003 – Milk and milk products – Guidelines for a standardized description of competitive enzyme immunoassays – Determination of aflatoxin M1 content
This standard give guidelines on the use of screening methods used for the determination of aflatoxin M1 content in milk and milk products, based upon competitive enzyme immuno-assays. For legal purposes, positive enzyme immunoassay results require confirmation by an accepted reference method. However, depending on whether the test complies with the specifications given hereafter, enzyme […]
ISO 14891 | IDF 185: 2002 – Milk and milk products – Determination of nitrogen content – Routine method using combustion according to the Dumas principle
This International Standard specifies a routine method for the determination of the total nitrogen content of milk and milk products.
ISO 13969 | IDF 183: 2003 – Milk and milk products – Guidelines for a standardized description of microbial inhibitor tests
This standard gives guidance for a standardized description of microbial inhibitor tests for milk and milk products. It is intended to give a framework and basis for the evaluation/validation of microbial inhibitor tests, allowing the comparison of data obtained from different tests and experimental studies.
