- 8. The composition of claim 7, wherein said antioxidant is selected from the group consisting of caffeic acid, rosmarinic acid, gallic acid, ferulic acid, coumaric acid, precursors of the foregoing, and mixtures thereof.
- 9. The composition of claim 1, wherein said material is a biological extract.
- 10. The composition of claim 9, wherein said biological extract is selected from the group consisting of a tea extract, a grape seed extract, a soy extract, a corn extract, and mixtures thereof.
- 11. The composition of claim 1, wherein said material is an enzyme.
- 12. The composition of claim 11, wherein said enzyme is selected from the group consisting of a protease, a lipase, a lactase, a xylanase, a cellulose, a phosphatase, a glycosyl tranferase, a nuclease, and mixtures thereof.
- 13. The composition of claim 1, wherein at least about 80% of said reduced malto-oligosaccharide species have a DP greater than 5.
- 14. The composition of claim 1, wherein at least about 60% of said reduced malto-oligosaccharide species have a DP greater than 8.
- 15. The composition of claim 1, wherein at least about 60% of said reduced malto-oligosaccharide species have a DP greater than 10.

- 17. The composition of claim 1, wherein at least about 75% of said reduced malto-oligosaccharide species have a DP greater than 5 and at least about 40% of said reduced malto-oligosaccharide species have a DP greater than 10.
- 18. The composition of claim 1, said preserving agent comprising a reduced malto-oligosaccharide species that has been prepared by catalytically reducing a mixture of malto-oligosaccharide species under reaction conditions suitable to substantially preserve the DP profile of said mixture.
- 19. The composition of claim 1, wherein at least about 40% of said reduced malto-oligosaccharide species have a DP greater than 10.
- 20. The composition of claim 13, wherein at least one of said reduced malto-oligosaccharide species has a DP greater than 10.
- 21. A composition comprising a material that is susceptible to degradation and preserving agent present in an amount effective to inhibit the degradation of said material, said preserving agent comprising one or more reduced malto-oligosaccharide species, said reduced malto-oligosaccharide species comprising a reduced maltodextrin.
