Foodstuffs - Determination of nitrate and/or nitrite content - Part 7: Continuous flow method for the determination of nitrate content of vegetables and vegetable products after Cadmium reduction

This European Standard specifies a continuous flow method (CF-method) for the determination of nitrate content of vegetables and vegetable products having a nitrate content of 900 mg/kg to 5200 mg/kg (calculated as nitrate ion). Note: Experiences have shown that the method may also applied for vegetables and vegetable products having a nitrate content of greater than 50 mg/kg (calculated as nitrate ion).

Foodstuffs - Determination of nitrate and/or nitrite content - Part 2: HPLC/IC method for the determination of nitrate content of vegetables and vegetable products
SIST EN 12014-2:2018

This European Standard specifies a high-performance liquid chromatographic (HPLC) and an ion chromatographic (IC) method for determination of the nitrate level in vegetables and vegetable products. This method is applicable for samples with a content of 25 mg/kg or greater.
It has been validated on naturally contaminated and spiked samples as beetroot juice with nitrate mass fractions of 194 mg/kg and 691 mg/kg, pureed carrots with nitrate mass fractions of 26 mg/kg and 222 mg/kg and with iceberg lettuce with nitrate mass fractions of 623 mg/kg and 3 542 mg/kg.

Foodstuffs - Determination of acrylamide in food and coffee by gas chromatography-mass spectrometry (GC-MS)
SIST-TS CEN/TS 17083:2017

This Technical Specification specifies a method for the determination of acrylamide in cereal-based products, potato-based products and coffee by gas-chromatography mass spectrometry (GC-MS).
The method has been single-laboratory validated via the analysis of spiked samples (French fries (uncooked), bread, water biscuit, infant cereal, biscuit, green coffee, roast coffee and instant coffee), ranging from 30 μg/kg to 1 500 μg/kg acrylamide.
The results from the single laboratory validation were obtained by a laboratory with significant experience in acrylamide analysis. In addition, this method has also been studied by inter laboratory trial via the analysis of samples containing incurred acrylamide, ranging from approximately 200 μg/kg to 2 000 μg/kg. Critical points of the method are identified in 7.5 and Clause 8.

Food analysis - Determination of acrylamide in food by liquid chromatography tandem mass spectrometry (LC-ESI-MS/MS)
SIST EN 16618:2015

This European Standard specifies a method for the determination of acrylamide in bakery ware such as bread, toasted bread, crisp bread, butter cookies, and biscuits, as well as potato products such as potato chips, potato crisps, and potato pan cake and roasted coffee, by liquid chromatography in combination with electrospray ionization and tandem mass spectrometry (LC-ESI-MS/MS). This method has been validated in an interlaboratory study via the analysis of both naturally contaminated and spiked samples, ranging from 14,3 µg/kg to 9 083 µg/kg. It was developed at the Swedish National Food Administration and validated in a study organized by the Directorate General Joint Research Centre (DG JRC), Swedish National Food Administration and the Nordic Committee on Food Analysis (NMKL), see [1] and [2].
The limit of quantification (LOQ) depends on the type of instrument used and on the actual performance of the instrument. The majority of the laboratories participating in the validation study were able to determine acrylamide in a butter cookie sample at a level of 14,3 µg/kg. Thus, the validation by interlaboratory study showed that LOQ can be expected to be in the range between below 15 µg/kg and 30 µg/kg.

-   used by one operator at a time;
-   used to deposit only pasty food (i.e.: cream, dough, batter, etc.);
-   used to deposit only on trays;
-   used as standalone machines;
-   used with manual loading of the dough into the hopper;
-   used with manual loading and unloading of the tray/s on/from the tray conveyor.
b)   can carry out only the following movements and relevant directions (see Figure 1a)):
-   Z: vertical movement of the table and/or the deposit unit;
-   X: horizontal movement of the tray conveyor;
-   Y: possible horizontal component of the movement only of the spouts themselves inside the deposit unit;
c)   are fitted with one or more hoppers whose capacity is ≤ 60 dm3 each;
d)   have a total length of the tray conveyor ≤ 1 600 mm;
e)   have a vertical movement between spouts and tray conveyor (H) ≤ 200 mm (see Figure 1c));

-   ≤ 100 cycles/minute without up/down movement of the table or the deposit unit;
g)   have a trays performance (see 3.6) ≤ 4 trays/minute.
This document deals with all significant hazards, hazardous situations and events relevant to adjustment, operation and cleaning of craft bakery and pastry depositors, when they are used as intended or under conditions of misuse which are reasonably foreseeable by the manufacturer.
This document covers requirements for the safe operation of the machine, including loading, depositing, unloading and cleaning.
1.2 The following hazards are not covered by this document:
-   hazards arising from the use of an automatic hopper loading system;

-   hazards due to surfaces, edges or angles;
-   hazards due to uncontrolled movements;
-   hazards due to machinery maintenance.
This standard does not deal with any specific requirements on noise emitted from craft bakery and pastry depositor as the generated noise does not cause a relevant hazard.
The significant hazards covered by this document are described in Annex B.
1.3 The following machines are excluded from the scope of this document:
a)   machines which deposit pasty food by means of needles (injection);
b)   machines where the trays are put onto and/or removed from the tray conveyor automatically;
