ICS 67 is a classification code in the International Classification for Standards (ICS) system. It covers "FOOD TECHNOLOGY". The ICS is a hierarchical classification system used to organize international, regional, and national standards, facilitating the search and identification of standards across different fields.
There are 4518 standards classified under ICS 67 (FOOD TECHNOLOGY). These standards are published by international and regional standardization bodies including ISO, IEC, CEN, CENELEC, and ETSI.
The International Classification for Standards (ICS) is a hierarchical classification system maintained by ISO to organize standards and related documents. It uses a three-level structure with field (2 digits), group (3 digits), and sub-group (2 digits) codes. The ICS helps users find standards by subject area and enables statistical analysis of standards development activities.

This document specifies a procedure for determining hydroxyacyl-coenzyme A dehydrogenase (HADH) activity in poultry meat samples by spectrophotometry. The results provide an indication of whether poultry breast meat has been previously frozen, based on the ratio of relative HADH activity, and can be used to verify the labelling of poultry breast meat sold as chilled poultry.
This document is applicable specifically to chicken breast meat. It is not applicable to other cuts and/or types of meat unless these have been validated and appropriate limits have been established.
When following the procedure outlined in this document, for a single sample pressing results in 96,6 % of samples being correctly classified. If a correct classification rate of 99,9 % is required, three sample pressings are necessary; i.e. three chicken breasts (one pressing from each), selected randomly from a batch.
This document is not applicable to minced meat or to poultry preparations.

This document specifies a rapid method for the determination of the oil and water contents in oilseeds using pulsed nuclear magnetic resonance (NMR). It is applicable to rapeseeds, linseeds and sunflower seeds with a water content less than 10 % and soya beans with a water content less than 14 %. For seeds with higher water contents, drying is necessary before the water and oil content can be determined by pulsed NMR. NOTE 1 This method has been tested with rapeseeds, soya beans, linseeds and sunflower seeds. This does not, however, preclude its applicability to other commercial seeds whose oil is liquid at the temperature of measurement. NOTE 2 The reproducibility values obtained are generally higher than those obtained by the reference methods (see ISO 659 and ISO 665) because they depend on the variability between the instruments and on that existing between the calibrations, which depends on the measurement accuracy of the reference methods. NOTE 3 The results of the comparison test between different magnets and different volumes of seed samples (see Annex B) are in coherence with the results of the interlaboratory test (see Annex A).

This document specifies a procedure for determining whether a perceptible sensory difference or similarity exists between samples of two products. The method is a forced-choice procedure. The method is applicable whether a difference exists in a single sensory attribute or in several attributes.
The method is statistically less efficient than the triangle test (described in ISO 4120) but is easier to perform by the assessors.
The method is applicable even when the nature of the difference is unknown (i.e. it determines neither the size nor the direction of difference between samples, nor is there any indication of the attribute(s) responsible for the difference). The method is applicable only if the products are fairly homogeneous.
The method is effective for:
determining that either:
a perceptible difference results (duo-trio testing for difference); or
a meaningful perceptible difference does not result (duo-trio testing for similarity) when, for example, a change is made in ingredients, processing, packaging, handling or storage;
selecting, training and monitoring assessors.
Two forms of the method are described:
the constant-reference technique, used when one product is familiar to the assessors (e.g. a sample from regular production);
the balanced-reference technique, used when one product is not more familiar than the other.

Laboratory experience has shown that this document can also be applied to other marine invertebrates [2], [3] and processed products of those species, however, no complete interlaboratory validation study according to ISO 5725-2 [21] has been carried out so far. The method described was validated in an interlaboratory study [4], [5] and was also verified in a European Union Reference Laboratory for Marine Biotoxins (EURLMB)-performance test aiming the total toxicity of the samples [6]. Toxins which were not available in the first interlaboratory study [4], [5] as dcGTX2,3 and dcNEO were validated in two additional interlaboratory studies [7], [8]. The lowest validated levels [4], [5], [8], are given as mass fraction of toxin (free base) in µg/kg shellfish tissue and also as µmol/kg shellfish tissue and are listed in Table 1.
[Table 1 - Lowest validated levels]
A quantitative determination of GTX6 was not included in the first interlaboratory study but several laboratories detected this toxin directly after solid phase extraction with ion-exchange (SPE-COOH) clean-up and reported a mass fraction (free base) of 30 µg/kg or higher in certain samples. For that reason, the present method is applicable to quantify GTX6 directly, depending on the availability of the standard substance. Whenever GTX6 standard is not commercially available, it is possible to determine GTX6 after hydrolysis of Fraction 2 of the SPE-COOH clean-up, described in 7.4, as NEO. The indirect quantification of GTX6 was validated in two additional interlaboratory studies [7], [8]. A study to compare direct and indirect GTX6 quantification was conducted at the EURLMB [16].
A quantitative determination of C3,4 was included in the first interlaboratory study. The present method is applicable to quantify C3,4 directly, depending on the availability of the standard substance. If no standard substances are available, C3,4 can only be quantified as GTX1,4 if the same hydrolysis protocol used for GTX6 (7.4) is applied to Fraction 1 of the SPE-COOH clean-up [10]. A study to compare direct and indirect C3,4 quantification was conducted at the EURLMB [16].

The method described was validated in an interlaboratory study [4], [5] and was also verified in a European Union Reference Laboratory for Marine Biotoxins (EURLMB)-performance test aiming the total toxicity of the samples [6]. Toxins which were not available in the first interlaboratory study [4], [5] as dcGTX2,3 and dcNEO were validated in two additional interlaboratory studies [7], [8]. The lowest validated levels [4], [5], [8], are given as mass fraction of toxin (free base) in µg/kg shellfish tissue and also as µmol/kg shellfish tissue and are listed in Table 1.
[Table 1 - Lowest validated levels]
A quantitative determination of GTX6 was not included in the first interlaboratory study but several laboratories detected this toxin directly after solid phase extraction with ion-exchange (SPE-COOH) clean-up and reported a mass fraction (free base) of 30 µg/kg or higher in certain samples. For that reason, the present method is applicable to quantify GTX6 directly, depending on the availability of the standard substance. Whenever GTX6 standard is not commercially available, it is possible to determine GTX6 after hydrolysis of Fraction 2 of the SPE-COOH clean-up, described in 7.4, as NEO. The indirect quantification of GTX6 was validated in two additional interlaboratory studies [7], [8]. A study to compare direct and indirect GTX6 quantification was conducted at the EURLMB [16].
A quantitative determination of C3,4 was included in the first interlaboratory study. The present method is applicable to quantify C3,4 directly, depending on the availability of the standard substance. If no standard substances are available, C3,4 can only be quantified as GTX1,4 if the same hydrolysis protocol used for GTX6 (7.4) is applied to Fraction 1 of the SPE-COOH clean-up [10]. A study to compare direct and indirect C3,4 quantification was conducted at the EURLMB [16].

This document specifies a method for the analysis of pesticide residues in foods of animal origin with a low fat content, such as meat/muscle, egg or milk by LC-MS/MS. Because of the low material requirements for miniaturized processing and the few work steps, the process is particularly time and cost-saving with high reliability and effectiveness. The method has been collaboratively studied on a number of commodity/pesticide combinations. Precision data are summarized in Table B.1. Guidelines for calibration are outlined in CEN/TS 17061:2019.
