Specific Comments 

rd

In consistency with the Procedural Manual, 23 , page 68, we consider that, preferably, it should be presented the performance criteria for the methods of analysis for the proposed nutrients in infant formula: “General Criteria for the Selection of Methods of Analysis using the Criteria Approach In the case of Codex Type II and Type III methods, method criteria may be identified and values quantified for incorporation into the appropriate Codex commodity standard” (Procedural Manual, rd 23 , page 68). The instructions for the development of specific criteria are outlined in Table 1 of the Procedural rd Manual, 23 , page 70: Guidelines for establishing numeric values for the criteria. Furthermore, it would be important to mention the standard methods that meet these criteria. Thereby, member countries would have options for choosing the methods.

If the Committee does not support the aforementioned suggestion, we would like to present the following comments with respect to the methods of analysis listed in TABLE 1: Initially, we highlight that methods described as ISO/DIS are methods under revision, thus, it should not be endorsed before the final approval.

Nevertheless, based on the Procedural Manual, 23 , page 68, we understand that the method AOAC 986.23, currently endorsed as type II in CODEX STAN 234-1999 for this provision with the principle “Turbidimetric”, should be endorsed as type III. Thus, countries may use it for control, inspection or regulatory purposes: “The method selected should be chosen on the basis of practicability and preference should be given rd to methods which have applicability for routine use” (Procedural Manual, 23 , page 68).

Thus, countries may use it for control purposes. Furthermore, the United States of America suggest recommending to CCMAS that the method AOAC 992.17 for pantothenic acid that may be replaced by the methods in Table 1 and are not validated for infant formula be removed or reclassified. However, we point out that this method is not listed in Codex Stan 234 and that it is used for analysis of pesticide residues in vegetables/potatoes. The method currently listed in Codex Stan 234 for pantothenic Acid in infant formula is the method 992.07:

COLOMBIA Colombia esta de acuerdo con iniciar el trabajo para Métodos de análisis de la Norma para preparados para lactantes y preparados para usos medicinales especiales destinados a los lactantes; y que se solicite remitir al CCMAS ocho métodos de análisis de nutrientes de preparados para lactantes —vitamina B12, mioinositol, cromo, selenio, molibdeno, nucleótidos, vitaminas A y E, perfil de ácidos grasos, yodo y ácido pantoténico— para que éste lleve a cabo una revisión técnica de los mismos, les adjudique un tipo, los ratifique y los incluya en los Métodos de análisis y de muestreo recomendados (CODEX STAN 234-1999). ECUADOR English: General Comments Ecuador agrees to bring to the attention of the Codex Committee on Methods of Analysis and Sampling the eight methods of nutrient analysis of infant formula. However, Ecuador does not agree to consider the possibility of eliminating the methods that are included in the methods of analysis and sampling recommended (CODEX STAN 234-1999) Rationale: Some countries may not be able to adopt new methods of analysis, and, if it is decided to not eliminate methods that are included in the methods of analysis and sampling recommended (CODEX STAN 2341999), countries would have at least a second option in which to base their methods of analysis, so it is suggested not to remove them, and propose them as a second option. Español: Comentarios Generales: Ecuador está de acuerdo en poner a consideración del Comité de Codex sobre Métodos de Análisis y toma de Muestras los ocho métodos de análisis de nutrientes de preparados para lactantes.Sin embargo, Ecuador no está de acuerdo en considerar la posibilidad de eliminar los métodos que se encuentran incluidos en los Métodos de análisis y de muestreo recomendados (CODEX STAN 234-1999) Justificación: Algunos Países podrían no estar en condiciones de adoptar los nuevos métodos de análisis, y, al no eliminar los métodos que se encuentran incluidos en los Métodos de análisis y de muestreo recomendados

(CODEX STAN 234-1999), los países al menos tendrían una base o una opción secundaria en cual sustentar sus métodos de análisis, por lo que se sugiere no eliminarlos, y proponerlos como una opción secundaria. EUROPEAN UNION Mixed competence Member States vote The European Union and its Member States would like to submit the following comments: The proposed AOAC/ISO/(IDF) methods have been recently validated by an AOAC led consortium of infant formula manufacturers. They represent the current state-of-the-art and as some of the related methods listed in STAN 234 are indeed outdated it is appropriate that CCNFSDU requests CCMAS to review them and decide whether they can be endorsed. For some of the provisions contained in STAN 72 methods of analysis are indeed missing in STAN 234. For example, no method has been endorsed and included in STAN 234 for myo-inositol and nucleotides, although the latter are only mentioned under optional ingredients and no minimum/maximum values are given in the standard. For the other provisions mentioned STAN 234 contains endorsed methods and a number of them, in particular the European Norms, are still valid and in use (see overview below).

Conclusions and recommendations As all concerned provisions relate to rationale analytes where the stoichiometry of the compounds concerned is known, the criteria approach is applicable. This would allow keeping the currently used methods in the system, provided they fulfil the required criteria, and let analysts choose among those methods that best meet their needs. No validation data are available for the determination of vitamin B12 by AOAC 986.23 and it could be replaced by the newly developed AOAC 2011.10 as the Type II method if CCNFSDU does not opt for the criteria approach. For the determination of chromium, selenium and molybdenum appropriate European Standards exist (EN 14082, EN 14083, EN 14627) which should be kept in the Codex system, preferentially by using the criteria approach. The proposed AOAC/ISO method for vitamin A does not quantify all forms of the vitamin, only retinyl palmitate and retinyl acetate, while the provisions of STAN 72 relate to all-trans-retinol. Since no saponification is foreseen in the AOAC/ISO method, naturally present retinyl esters of milk fat escape determination. Regarding vitamin E STAN 72 relates to d-α-tocopherol, while the measurands in the

CRD 10

8

AOAC/ISO standard is dl- α-tocopherol and dl- α-tocopheryl acetate, which have a different biological activity compared to d-α-tocopherol. Moreover, other forms of vitamin E such as β-, γ-, δ-tocopherol are not covered by the proposed AOAC/ISO standard. Therefore, CCNFSDU may be invited to specify to greater detail the provision for vitamin E, in particular which vitamers are considered to represent vitamin E. For this reason it is not recommended to request submission of AOAC 2012.10/ISO/DIS 20633 for review to CCMAS. In case, the committee decides otherwise, the criteria approach is recommended since appropriate European Standards (EN 12083-1, EN 12822) exist and are in use. For the determination of fatty acids by AOAC 2012.13/ISO/DIS 16958/IDF 231 no validation data were found in AOAC 2012.13; however, they may be included in the equivalent ISO and IDF standards. INDONESIA In principle Indonesia agrees with the proposal of Methods of analysis in the Standard for Infant Formula and Formulas for Special Medical Purposes Intended for Infants (CODEX STAN 72-1981) MALI Problème: Méthodes officielles de l’AOAC validées dans les préparations destinées aux nourrissons avec des références ISO/DIS Position: Le Mali soutient la mise à jour des méthodes de tests tels que proposés. Nous recommandons qu’au lieu du Projet de norme international (DIS), le comité entre en liaison avec le Secrétariat de l’Organisation internationale de Normalisation (ISO) pour confirmer le statut de DIS. S’ils sont encore sous forme de projet, le Mali soutient seulement le texte publié de l’AOAC et le maintien d’ISO/DIS. Justification: La mise à jour de la méthode d’essai facilitera l’analyse des produits destinés aux nourrissons sur base d’informations scientifiques actualisées et d’équipements modernes. Cependant, l’adoption d’un projet de norme n’est pas acceptable parce que le texte final peut changer en fonction de la discussion au sein du processus de l’ISO comme cela figure généralement dans leurs avertissements sur les projets de normes, d’où l’importance d’adopter des textes définitifs. MEXICO México agradece la oportunidad de realizar comentarios al documento CX/NFSDU 15/37/10, respecto a los Métodos de análisis de la Norma para preparados para lactantes y preparados para usos medicinales especiales destinados a los lactantes (CODEX STAN 72-1981), correspondiente al Tema 11 de la Agenda de la próxima reunión del CCNFSDU.

El método AOAC 2011.19 debería ser clasificado como Tipo III, con base en los Criterios para la selección de Métodos de Análisis sobre la practicabilidad, por el alto costo de los equipos. Aunque el método propuesto (ICP-MS) permite efectuar el análisis de los tres minerales en la misma corrida, la inversión para su adquisición es alta y son pocos los laboratorios que cuentan con él.

Estamos de acuerdo con su adopción así como su clasificación como Tipo II, ya que se requiere de un equipo de cromatografía de líquidos básico. Estamos de acuerdo con su adopción, así como su clasificación como Tipo II. Para el método actual se requiere de dos metodologías diferentes. Con el AOAC 2012.10 es un solo método y se hace una sola preparación y un solo tratamiento de la muestra, solo que se requieren de dos detectores, uno de ultravioleta y otro de fluorescencia. Estamos de acuerdo con su adopción, así como su clasificación como Tipo II, ya que con este método, no se requiere la extracción de la grasa de la muestra, lo cual disminuye los tiempos de análisis. El equipo requerido de Cromatografía de Gases es el mismo con detector de Ionización de Flama. Sugerimos mantener el método AOAC 992.24 de Ion selectivo como Tipo II, ya que es un método más práctico y económico.

English: Morocco believes that the new methods described in Table 1 and especially those concerning mineral elements, ie, chromium, selenium, molybdenum and iodine, are methods that are based on the technique of emission Atomic ICP-MS. Given the fact that this material is extremely expensive for some countries, and the determination of these elements particularly chromium, selenium and molybdenum can be performed with high sensitivity by the technique of atomic absorption spectrometry (Graphite furnace for the determination of Cr and Mo, or hydride generation for the determination of Se) which is less expensive than the ICP-MS, we propose to the committee, to consider in addition to the proposed methods, other methods based on the technique of atomic absorption spectrometry ; This can be used by the countries that do not have the ICP-MS. Justification: The high cost of ICP-MS equipment is main barrier to the use of this method by developing countries. For this, we should think of other methods that can be used and reliable and it is the case of the atomic absorption spectrophotometer. Français: Le Maroc estime que les nouvelles méthodes décrites dans le tableau 1 et surtout celles qui concernent les éléments minéraux, à savoir, le chrome, le sélénium, le molybdène et l’iode , sont des méthodes qui se basent sur la technique de l’émission atomique ICP-MS. Sachant que cet instrument est extrêmement cher pour certains pays , et que la détermination de ces éléments surtout le chrome , sélénium et molybdène peut être effectuée avec une grande sensibilité par la technique de la spectrométrie d’absorption atomique ( technique du four à graphite pour le chrome et molybdène et technique du générateur d’hydrures pour le sélénium ) et qui ne coute pas aussi cher que l’ICPMS, pour cette raison, nous proposons au comité d’envisager , en plus des méthodes proposées , des méthodes qui se basent sur la technique de la spectrométrie d’absorption atomique qui seront utilisées par les laboratoires qui ne disposent pas de L’ICP-MS . Justification : La cherté du matériel ICP-MS constitue une entrave à l’utilisation de cette méthode par les pays en voie de développement. Pour cela, il faudrait penser à d’autres méthodes que l’on peut utiliser qui soient aussi fiables et c'est le cas de la spectrophotométrie d'absorption atomique. AFRICAN UNION Issue: AOAC Official Methods validated in Infant Formula with ISO/IDF References Position: AU supports the updating of the methods of tests as proposed. AU recommends that rather than Draft International Standards (DIS), the committee liaise with ISO secretariat to confirm the status of DIS. If they are still in draft form, AU supports only the published text of AOAC and IDF and hold the ISO/DIS Rationale: Updated method of test will facilitate the analysis of infants products based on updated science and modern equipments. However, adoption of a draft standard is not acceptable because the final text may change depending on the discussion within the ISO process as usually indicated in their disclaimers to the draft standards, and hence the importance of adopting the final texts.
