Definitions
- the present invention relates to a mycotoxin adsorbent, in particular for the adsorption of aflatoxins and other mycotoxins (non-aflatoxins) in animal feed.
- mycotoxins is a group of toxic substances that are formed by various naturally occurring fungi. Around 300 to 400 mycotoxins are currently known. Cereals and grains are generally regarded as the natural habitat for these mushrooms. While some types of mushrooms are already on the develop ripening grain of grain in the ear, other types primarily affect stored grain stocks, if a certain minimum humidity and ambient temperature is given.
- mycotoxins have a harmful effect primarily on farm animals fed with infected cereals, but also secondarily on humans via the food chain.
- the aflatoxins for example, are responsible for the so-called X-disease of turkeys, which killed around 100,000 animals in Great Britain in 1960/61 that had been fed with moldy peanut flour.
- Aflatoxin -3 ⁇ , B2, G lf G2 are formed by various Aspergillus species.
- Aflatoxin Bx is already carcinogenic in microgram amounts and causes damage to the stomach and liver.
- Ochratoxin is produced by Aspergillus ochraceus and Penicilliu viridicatum and causes kidney damage.
- Zearalenon is produced by Fusarium gra inearum, which grows on corn, barley and wheat. It is an estrogen-like substance that causes fertility problems and is suspected of being carcinogenic.
- Fu onisin is and is formed by fungi of the genus Fusarium. et al is held responsible for horse deaths.
- T2 toxins and T2-like toxins are formed by fungi of the genus Fusarium.
- mycotoxins such as deoxynivalenol, diacetoxyscirpenol, patulin, citrinin, byssochlamic acid, ochratoxin, sterigmatocystin, moniliformin, ergot-alkali loide, ergochromes, cytochalasans, penicillinic acid, zearalenone, rubratoxins, thrichothecenes (cf. R ⁇ mpps, Chemie-Lexikon, 8th edition, 1985, p. 2888), and others, which, however, only occasionally occur in such concentrations in feeds that are harmful to health Cause problems.
- mycotoxins such as deoxynivalenol, diacetoxyscirpenol, patulin, citrinin, byssochlamic acid, ochratoxin, sterigmatocystin, moniliformin, ergot-alkali loide, ergochromes, cytochalasans
- the group of aflatoxins is due to their specific molecular structure with high specificity to some mineral adsorbents such as zeolite, bentonite, aluminum silicate and others fixed (see A.-J. Ramos, J. Fink-Gremmels, E. Hernandez, "Prevention of Toxic Effects of Mycotoxins by Means of Nonnutritive Adsorbent Compounds, J. of Food Protection, Vol. 59 (6), 1996 , Pp. 631-641) However, this is not the case for most other mycotoxins, and attempts have been made to extend the adsorption capacity of mineral adsorbents to include non-aflatoxins.
- WO 91/13555 describes a dry, particulate animal feed additive which contains phyllosilicate particles which are coated with a sequestering agent. An increase in the sorption rate can be achieved in this way, but complete (> 90%) removal of the toxins used cannot be achieved. Although good results are described in the prior art with ion exchange resins or high-quality activated carbons, such solutions are not relevant in practice for reasons of cost.
- Organophilic clays are used used in the prior art for the treatment of liquid waste with organic impurities in order to solidify it and to facilitate disposal (cf. EP-0, 560, 423).
- the object of the present invention is to provide an adsorbent based on layered silicates (phyllosilicates) which not only adsorbs aflatoxins but also other important mycotoxins (non-aflatoxins) with high effectiveness and at the same time is so inexpensive that it is practical can be used. Furthermore, the adsorbent should also have a stable adsorption of mycotoxins under physiological conditions, such as occur, for example, after ingestion with the feed in the digestive tract of the farm animals.
- mycotoxin adsorbents can be provided by suitable modification of a layered silicate or a part thereof, which can effectively adsorb both aflatoxins and non-aflatoxins such as zearalenone, ochratoxin, deoxynivalenone, T2 toxins or fumonisin are inexpensive.
- a layered silicate with a quaternary onium compound having a long chain CIO to C22 -A lkyl- the adsorption performance can according to a first aspect of the invention by modifying group and at least one aromatic substituent, and with a relatively small amount thereof, already a significant increase of such Material for mycotoxins can be achieved.
- the layered silicates which can be used in the adsorbent according to the invention include the layered silicates listed in Ull anns Encyklopadie der Technische Chemie, Vol. 21, pp. 370-375 (1982). silicates.
- the activatable natural and synthetic clay minerals such as smectites including montmorillonite, beidellite, nontronite, Wolchonskoit, stevensite, hectorite, Swinefordite, saponite and sauconite, the vermiculite, the illite, the alternate storage minerals (ixed layer minerals) and palygorskite Sepiolite can be used. The latter two are also known as hormites.
- the layered silicate is a three-layered silicate, for example a naturally occurring smectite clay, in particular a bentonite clay.
- a naturally occurring smectite clay in particular a bentonite clay.
- Particularly preferred are swellable layered silicates with a relatively high swelling volume, such as calcium bentonites with a swelling volume of about 10 ml / g or more, or layered silicates converted into the Na + form with an swelling volume of about 20 ml / g or more. It is assumed that the specific swelling capacity is positively influenced by the high swellability. However, acid-activated bentonites can also be used.
- the adsorbents according to the invention show a considerable adsorption capacity for mycotoxins even when 2 to 30%, preferably 2 to 15%, in particular 2 to 10% of the KAK are exchanged.
- a bentonite with a cation exchange capacity of 50 to 100 meq / 100 g can be coated uniformly with an amount of onium ions which correspond to about 3 to 15 meq / 100 g.
- Quaternary ammonium compounds and pyridinium compounds in particular can be used as quaternary onium compounds.
- the quaternary onium compounds contain (at least) one long-chain C ⁇ o ⁇ to C 2 2 -A alkyl group and at least one aromatic substituent, in particular all onium compounds which are suitable for the organic modification of layered silicates and are known to the person skilled in the art in this field , be used.
- the quaternary onium compounds can, for example, also contain an aralkyl substituent (as an aromatic substituent).
- the quaternary onium compound used is stearyl (taig fat) benzyl dirnethyl ammonium chloride (Cig-C-ig-DMBA).
- Other preferred onium compounds are:
- Coco-alkyl-dimethyl-benzyl-ammonium chloride (Ci 2 -C 1 6 ⁇ DMBA ) dimethyl-lauryl-benzyl-ammonium chloride (C 1 2-C 14 -DMBA) distearyl-methyl-benzyl-ammonium chloride (Cig-Cxg-DMBA) quaternized taig fat -I idazolinium methasulfate.
- the quaternary onium compounds can either be used directly or can be formed by using secondary and tertiary amines together with acid in situ during the activation of the layered silicate.
- the adsorbents according to the invention in the case of a drop in the pH value, as occurs, for example, when feeding animal feed into the acidic gastric environment of a monogastric livestock, or also when changing from an acidic to a neutral or slightly alkaline pH value, as occurs during the passage of the Food pulp through the digestive tract, have an efficient and stable adsorption of mycotoxins.
- the mycotoxin adsorbent contains a mixture of an organically modified layered silicate and a non-organically modified layered silicate, the organically modified layered silicate contained in the mixture being exchanged with a quaternary onium compound at least 75%, based on the total KAK .
- the layered silicates used in accordance with this embodiment used according to the invention correspond to those given above.
- the mixture will contain about 0.1 to 50% by weight, in particular about 0.5 to 20% by weight, of organically modified layered silicate.
- organically modified layered silicate Surprisingly, it was found that even a proportion of more than about 2% by weight practically complete (more than 90%) adsorption of the mycotoxins (aflatoxins and non-aflatoxins) takes place on organically modified layered silicate in the mixture, even at acidic pH values. It is therefore believed, without being limited to a theoretical mechanism, that the hydrophobic surface of the organically modified layered silicate and the surface of the unmodified layered silicate cooperate in the effective adsorption and low desorption of the mycotoxins.
- the aflatoxins primarily bind to the unmodified phyllosilicate, so that the surface of the organically modified phyllosilicate for the adsorption of the non-aflatoxins, which does not adhere to the unmodified Layered silicate can be adsorbed is available. This ensures good absorption performance with regard to the non-aflatoxins, even at relatively high aflatoxin concentrations.
- organically modified layered silicate represents the essential cost factor of the mixture
- the lowest possible proportion of organically modified layered silicate in the mixture is selected in practice, but with a good adsorption performance.
- the optimum proportions of organically modified or unmodified layered silicate can be determined in individual cases on the basis of routine tests by a person skilled in the art.
- organically modified layered silicate are generally used in the mixture.
- the adsorption of the mycotoxins in an aqueous solution remains even with a drop in the pH value or a transition from acid to neutral or slightly alkaline pH, as below physiological conditions in the digestion of feed occurs, stable, ie the desorption rate is low.
- adsorbent mixture according to the invention is that due to the relatively lower proportion of organically modified layered silicate in the mixture, desired hydrophobic substances, such as lipophilic vitamins or essential fatty acids, are only bound to a small extent to the adsorbent and thus for the Absorption in the digestive tract is available.
- a feed additive which contains an adsorbent according to the invention.
- premixes which contain a fairly high proportion of more than about 50% of organically modified layered silicate and which are mixed with an unmodified layered silicate in a second step for producing an adsorbent according to the invention or a feed additive.
- the mycotoxin adsorbents of the invention may contain other ingredients that appear useful for the particular use, e.g. Feed additive or agent for (enzymatic) detoxification of mycotoxins.
- the cation exchange capacity was determined as follows:
- the NH 4 + content of the bentonite is then determined using the Kjeldahl method.
- the KAK of the clay is the NH 4 + content of the NH 4 + clay determined using Kjeldahl. The information is given in mval / lOOg clay.
- the various mycotoxins were obtained as pure crystalline substances (SIGMA AG) and taken up in methanol or acetonitrile (50 ⁇ g / ml).
- dilutions were prepared using buffer solutions (dipotassium hydrogen phosphate + (citric acid)), each containing 100 ⁇ g of the different toxins per liter.
- HDTMA hexadecyl trimethyl ammonium chloride
- ODDBMA octadecyl-dibenzyl-methyl-ammonium chloride
- organophilized bentonites were dried and finely ground so that the residue on a 90 ⁇ sieve was less than 10%. They were then added in each case in an amount of 0.02% by weight of aqueous solutions containing ycotoxin (100 ml), each of which contained 100 ⁇ g of the three mycotoxins aflatoxin Bl, ochratoxin A and zearalenone in 11 aqueous solution (pH 7).
