Abstract

The disclosure relates to a probiotic delivery system that can be consumed as a snack-food or added to a food product. In particular, the disclosure describes a crisp and tasty treat that comprises viable probiotic microorganisms preserved in a vacuum dried matrix of sugars, proteins, and polysaccharides. The probiotic remain viable within the treat for a longer time without the need for additional moisture barrier coating. The probiotic also remain viable in the animal gastrointestinal tract.

Claims

1. A probiotic substance comprising viable probiotic bacteria preserved in a dried matrix of at least one sugar, at least one protein, and at least one polysaccharide.

2. A probiotic substance according to claim 1, wherein the sugar in the dried matrix is a disaccharide.

3. A probiotic substance according to claim 2, wherein the disaccharide is selected from the group consisting of sucrose and trehalose.

4. A probiotic substance according to claim 1, wherein the protein in the dried matrix is selected from the group consisting of egg white, soy protein isolate, soy hydrolysate or a combination thereof.

5. A probiotic substance according to claim 1, wherein the polysaccharide is a cross-linkable gel, most preferably selected from the group consisting of a combination of alginates with different viscosities, agarose, pectin, and chitosan.

6. A probiotic substance according to claim 1, wherein the dried matrix is comprised of 20% w/v to 60% w/v trehalose, 2% w/v to 20% w/v egg white or soy protein isolate and 0.5% w/v to 10% w/v alginates.

7. A probiotic substance according to claim 1, wherein the probiotic microorganism comprises 10⁵ to 10¹⁴ viable micro-organisms per gram of dry substance.

8. A probiotic substance according to claim 1, wherein the probiotic substance is coated with additional moisture barrier.

9. A moisture barrier according to claim 8, wherein the barrier comprises any food-grade substance having water repelling or impermeable properties.

10. A moisture barrier according to claim 8, wherein the barrier comprises a mixture of oil based substances.

11. A probiotic substance according to claim 1 wherein the probiotic microorganism retain most of its initial biological activity after manufacturing, after extended exposure to high temperature and humid conditions and after gastric exposure.

12. A human food product comprising one or several probiotic substances comprising viable probiotic bacteria preserved in a dried matrix comprising at least one sugar, at least one protein, and at least one polysaccharide.

13. A human food product of claim 12, wherein the food product is in a moist, semi-moist, or semi-dry form.

14. A human food product of claim 12, wherein the food product is in a powdered, particulate, pellet, tablet, capsule, colloidal suspension or liquid form.

15. A human food product of claim 12, wherein the food product is added to a bar, liquid formula, or cereal or another food product.

16. A human food product of claim 12, wherein the food product is in the form of a treat, a nutraceutical food additive or a pharmaceutical food additive.

17. An animal feed product comprising one or several probiotic substances comprising viable probiotic bacteria preserved in a dried matrix comprising at least one sugar, at least one protein, and at least one polysaccharide.

18. An animal feed product of claim 17, wherein the feed product is in a moist, semi-moist, or semi-dry form.

19. An animal feed product of claim 17, wherein the feed product is in powdered, particulate, pellet, tablet, capsule, colloidal suspension or liquid form.

20. An animal feed product of claim 17, wherein the feed product is added to a bar, liquid formula, or cereal or another food product.

21. An animal feed product of claim 17, wherein the feed product is in the form of a treat, nutraceutical food additive or a pharmaceutical feed additive.

22. An animal feed product of claim 17, wherein the animal is chosen from terrestrial or aquatic animals.

23. A method of making probiotic food or feed substance comprising:

a) mixing a preparation of probiotic micro-organisms with at lease one sugar, at least one protein, and at least one polysaccharide to obtain a smooth and uniform gel in a desired shape and form;

and b) vacuum drying the preformed solid gel to a water activity below 0.1.
