  • Publication number: 20090227535
    Abstract: The present invention provides a process for producing ?-(3-(1,3/1,6)-D-glucan from a cellular source comprising the steps of alkali extraction of the cellular source; water extraction; acid extraction; and water extraction, where at least one step of water extraction includes pasteurization by steam injection to a temperature of about 100° C. for 15 to about 30 minutes. The solid component produced comprises at least ?-70% 1 (1,3/1,6)-D-glucan by dry weight. The present invention also provides a process of producing mannan and manno-protein complexes comprising the steps of collecting a liquid phase obtained in one an alkali extraction step of the ?(3-(1,3/1,6)-D-glucan process; adjusting the pH of the liquid phase to about 5.0-8.0 with an acid; pasteurizing the liquid phase by steam injection to a temperature of about 100° C. for 15 to about 30 minutes; and isolating the mannans and manno-proteins complexes from the pasteurized liquid phase.

  • Publication number: 20090092641
    Abstract: The present invention provides a method of improving disease management in an animal by administering an effective amount of ?-glucan composition to the animal. The ?-glucan composition comprises at least about 70% ?-(1,3/1,6)-D-glucan by dry weight and a biological activity of at least 20 ?g Bb released per mg of ?-(1,3/1,6)-D-glucan. The method may also result in beneficial secondary effects including an increase in growth efficiency of the animal; an increase in the survival rate of the animal; an increase in the colostrum quality of the animal; and any combination thereof. The ?-glucan composition may also be administered in combination with or prior to a vaccine, leading to an increase in antibody formation; the negative growth responses associated with administration of a vaccine may also be reduced. In the present method, the ?-glucan composition may be administered in combination with an animal feed.
