This part of ISO 18363 describes a procedure for the parallel determination of glycidol together with 2-MCPD and 3-MCPD present in bound or free form in oils and fats. The method is based on alkalinecatalyzed ester cleavage, transformation of the released glycidol into monobromopropanediol (MBPD) and derived free diols (MCPD and MBPD) with phenylboronic acid (PBA). Though free MCPD and glycidol are supposed to be present in fats and oils in low to negligible quantities only, significant content would increase proportionately the determination of bound analytes. This method is applicable to solid and liquid fats and oils. This part of ISO 18363 can also apply to animal fats and used frying oils and fats, but a validation study must be undertaken before the analysis of these matrices. Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of this international standard.

This European Standard describes a procedure for the determination of the citrinin content in food (cereals, red rice), herbs and food supplements by liquid chromatography tandem mass spectrometry (LC-MS/MS). This method has been validated for red yeast rice in the range of 2,5 μg/kg to 3000 μg/kg and for wheat flour in the range of 2,5 μg/kg to 100 μg/kg. Laboratory experiences have shown that this method is also applied to white rice, herbs such as a powder of ginkgo biloba leaves and the formulated food supplements.

1.1 This European Standard applies to the design and manufacture of standalone automatic dough dividers having a feed hopper, and which can be used separately or in a line in the food industry and shops (pastry making, bakeries, confectionery etc.) for dividing and additionally for moulding/rounding dough or pastry into adjustable portions to produce the required weight of dough piece during a dividing process. These machines can be fed by hand or mechanically. This European Standard deals with all significant hazards, hazardous situations and events relevant to the transport, installation, adjustment, operation, cleaning, maintenance, dismantling, disassembling and scrapping of automatic dough dividers, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). These machines are not intended to be cleaned with pressurized water. 1.2 This European Standard is not applicable to the following: - experimental and testing machines, under development by the manufacturer; - weighing devices; - pressure dough dividers, without a feed hopper, using knives for the dividing process; - lines with separate cutting or forming elements outside the housing; - lifting and tilting machines ) or other separate feeding machines; - additional hazards generated when the machine is used in a line or mechanically feed. 1.3 A noise test code is included in Annex A to assist manufacturers to measure noise levels for the purpose of the noise emission declaration. 1.4 This European Standard is not applicable to machines which are manufactured before its publication as EN.
