En nutraceutique, nous sommes confront\u00e9s r\u00e9guli\u00e8rement \u00e0 la probl\u00e9matique des fraudes sur les mati\u00e8res premi\u00e8res et en particulier sur les extraits botaniques. Ces fraudes sont g\u00e9n\u00e9ralement observ\u00e9es sur des mati\u00e8res dont la production co\u00fbte cher afin, justement, de faire baisser le co\u00fbt de production tout en maintenant le tarif appliqu\u00e9 aux laboratoires clients qui ach\u00e8teront la mati\u00e8re. Qu\u2019il s\u2019agisse de non-conformit\u00e9 quant \u00e0 l\u2019origine g\u00e9ographique, de mensonge sur la partie de plante utilis\u00e9e ou encore de l\u2019ajout de mol\u00e9cule active purifi\u00e9e d\u2019origine synth\u00e9tique alors qu\u2019elle devrait \u00eatre naturellement pr\u00e9sente, rien n\u2019est jamais trop facile pour augmenter le profit !<\/p>\n\n\n\r\n

  • Certaines mati\u00e8res premi\u00e8res, dont l\u2019extraction de principes actifs est difficile comme l\u2019extrait d\u2019ail noir, peuvent \u00eatre sujettes \u00e0 des fraudes par ajout de compos\u00e9s synth\u00e9tiques dans le but d\u2019attirer de nouveaux acheteurs.<\/li>\n\n\n\n
  • Lors du contr\u00f4le qualit\u00e9, un nouvel extrait d\u2019ail noir suppos\u00e9 de haute qualit\u00e9 standardis\u00e9 \u00e0 1% de SAC s\u2019est r\u00e9v\u00e9l\u00e9 suspect en raison de particules blanches visibles.<\/li>\n\n\n\n
  • Nos investigations ont mis en lumi\u00e8re des lacunes ind\u00e9niables en mati\u00e8re de qualit\u00e9 malgr\u00e9 une certification par un nouveau label fran\u00e7ais. Cela souligne l\u2019importance de v\u00e9rifier au-del\u00e0 des certificats.<\/li>\n\n\n\n
  • Nous avons choisi la qualit\u00e9 et la naturalit\u00e9 en maintenant notre collaboration avec notre fournisseur actuel d\u2019ail noir origine Espagne, m\u00eame si le taux de SAC est moins \u00e9lev\u00e9 (0,25%).<\/li>\n<\/ul>\n <\/div>\r\n\r\n<\/section>\n\n\n

    de la qualit\u00e9<\/h2><\/div>\n\n\n\n

    R\u00e9cemment, nous nous sommes trouv\u00e9s face \u00e0 une de ces situations : Alors que nous cherchons \u00e0 proposer des produits aux actifs toujours plus concentr\u00e9s et qualitatifs pour une meilleure efficacit\u00e9, un fournisseur europ\u00e9en, diff\u00e9rent de celui avec lequel nous travaillions jusqu\u2019alors, nous a propos\u00e9 un extrait d\u2019ail noir dont la standardisation en S-Allyl Cyst\u00e9ine, ou SAC, \u00e9tait de 1%, soit 4 fois plus \u00e9lev\u00e9e que celle de notre mati\u00e8re en stock. Lors de nos discussions, le fournisseur nous a indiqu\u00e9 toutes les garanties qualit\u00e9 du produit dont un nouveau label qualit\u00e9 europ\u00e9en de certification d\u2019authenticit\u00e9 portant sur les principes actifs v\u00e9g\u00e9taux et nous avons achet\u00e9 la mati\u00e8re.<\/p>\n\n\n\n

    Mais \u00e0 son arriv\u00e9e dans nos locaux, la surprise a \u00e9t\u00e9 de taille lors du contr\u00f4le visuel syst\u00e9matique. Elle contenait des particules blanches consid\u00e9rablement visibles \u00e0 l\u2019\u0153il nu au milieu de la poudre brune, comme le montre la photographie correspondante. Nous n\u2019avions jamais eu ce probl\u00e8me avec la mati\u00e8re standardis\u00e9e \u00e0 0.25% (ABG25+\u00ae).<\/p>\n\n\n

    \n
    \"Clich\u00e9s<\/figure>\n<\/div>\n\n\n

    Au fournisseur de nous r\u00e9pondre que la SAC a tendance \u00e0 cristalliser et que la mati\u00e8re \u00e9tant tr\u00e8s concentr\u00e9e, les cristaux sont nombreux. Nul doute que nous \u00e9tions bien en pr\u00e9sence de cristaux de SAC, mais le contraste avec la mati\u00e8re \u00e9tait tel qu\u2019il \u00e9tait plus que probable qu\u2019il s\u2019agisse d\u2019un ajout frauduleux de SAC purifi\u00e9e, s\u00fbrement synth\u00e9tique. Si la cristallisation \u00e9tait naturelle, les particules auraient plut\u00f4t eu tendance \u00e0 \u00eatre l\u00e9g\u00e8rement brunes mais pas d\u2019un blanc franc et nous en aurions vu \u00e9galement, dans une moindre mesure, dans notre extrait habituel d\u2019ail noir \u00e0 0.25%.<\/p>\n\n\n\n

    En allant plus loin dans notre questionnement sur la qualit\u00e9 de cette mati\u00e8re, nous avons d\u00e9couvert d\u2019une part que cet extrait d\u2019ail noir n\u2019\u00e9tait pas europ\u00e9en comme le fournisseur l\u2019avait sugg\u00e9r\u00e9 au d\u00e9part mais chinois (culture et fabrication) et que leur plan de contr\u00f4les pr\u00e9sentait des lacunes importantes en mati\u00e8re de contr\u00f4les de contaminants, ceux-ci n\u2019\u00e9tant analys\u00e9s m\u00eame pas une fois par an en Europe. Ces lacunes sont d\u2019autant plus probl\u00e9matiques dans un contexte d\u2019origine asiatique. La prise de recul sur les certifications et labels qualit\u00e9 est toujours essentielle car le processus d\u2019obtention peut finalement omettre certaines donn\u00e9es cl\u00e9 de la qualit\u00e9 du produit comme le plan de contr\u00f4les du fournisseur, comme on le constate bien ici.<\/p>\n\n\n\n

    Par ailleurs, les chromatogrammes respectifs des deux r\u00e9f\u00e9rences, obtenus en interne par technique LC\/MS, montrent bien la concentration plus importante en SAC dans l\u2019extrait \u00e0 1% mais aussi un profil bien moins riche de fa\u00e7on globale compar\u00e9 \u00e0 notre r\u00e9f\u00e9rence ABG25+\u00ae, ce qui renforce la probabilit\u00e9 d\u2019une fraude<\/p>\n\n\n

    \n
    \"Chromatogrammes<\/figure>\n<\/div>\n\n\n

    Ce cas illustre combien il est essentiel d\u2019\u00eatre vigilant face \u00e0 chaque changement de mati\u00e8re premi\u00e8re. La performance de nos contr\u00f4les qualit\u00e9 nous a permis de d\u00e9tecter ce cas et notre intransigeance a finalement men\u00e9 \u00e0 la d\u00e9cision de refuser et renvoyer le lot. Nous resterons fid\u00e8les \u00e0 notre fournisseur actuel, en qui nous avons toute confiance. Depuis plusieurs ann\u00e9es, il nous fournit toutes les garanties d\u2019une qualit\u00e9 irr\u00e9prochable, entrainant intrins\u00e8quement une efficacit\u00e9 optimale du produit et une pleine s\u00e9curit\u00e9 de consommation. Leur extrait d\u2019ail noir ABG25+\u00ae, origine 100% Espagne et brevet\u00e9, a \u00e9t\u00e9 largement \u00e9tudi\u00e9 cliniquement comme en atteste la litt\u00e9rature scientifique. Obtenu apr\u00e8s un processus de maturation et un proc\u00e9d\u00e9 d\u2019extraction aqueuse exclusif, cet extrait est pens\u00e9 pour \u00eatre le plus efficace possible tout en pr\u00e9sentant les garanties de naturalit\u00e9 de son actif (origine ail noir v\u00e9rifi\u00e9e, sans OGM, non-irradi\u00e9, sans nanoparticules, etc.).<\/p>\n\n\n\n

    Certes, l\u2019extrait que nous proposons n\u2019est pas standardis\u00e9 \u00e0 1% de SAC mais il est bien plus important pour nous de travailler des mati\u00e8res \u00e0 la qualit\u00e9 exemplaire et fournies par des entreprises de confiance. Le fournisseur de notre extrait ABG25+\u00ae a d\u2019ailleurs eu l\u2019honn\u00eatet\u00e9 de nous indiquer qu\u2019il leur \u00e9tait jusque-l\u00e0 impossible de maintenir la teneur de 1% de SAC sur l\u2019ensemble de la production d\u2019un lot d\u2019extrait d\u2019ail noir. Sans doute un indice de plus sur la fraude du second fournisseur europ\u00e9en.<\/p>\n\n\n\n\n","protected":false},"excerpt":{"rendered":"
