2. The composition of claim 1 characterized in that it comprises less than 0.1 wt % db of beta-glucan.
3. The composition of claim 1 characterized in that it has a mannose oligosaccharide content of mannose oligosaccharide having a degree of polymerization (DP) of 3 or more that is 60 wt % db or higher.
4. The composition of claim 1 characterized in that it has a dimannose content of from 10 to 25 wt % db.
5. The composition of claim 1 characterized in that it has a fructose content of 0.5 to 10 wt % db.
6. A food, animal feed or pet food product comprising the composition of claim 1 and further food, animal feed or pet food ingredients.
7. The food, animal feed or pet food product of claim 6 wherein the composition of claim 1 is present in an amount of from 0.1 to 0.5 wt % based on the weight of the food, animal feed or pet food product.
8. The food, animal feed or pet food product of claim 6 wherein the composition of claim 1 is present in an amount of from 0.01 to 0.05 wt % based on the weight of the food, animal feed or pet food product.
9. The composition of claim 1 for treating human or animal.
10. The composition of claim 1 for reducing or preventing bacterial attachment to the intestinal mucosa and/or for improving weight gain and/or improving feed intake and/or improving body weight gain and/or improving stool quality in human or animal.
11. The composition of claim 1 characterized in that it has a mannose content of 5 to 25 wt % db.
12. The composition of claim 1 characterized in that it has a glucose content of 1 to 15 wt % db.
13. A cosmetic, personal care or pharmaceutical product comprising the mannose oligosaccharide composition according to claim 1 , wherein the cosmetic product is a makeup cream, makeup lotion or lipstick; the personal care product is an oral care product, hair care product, skin care product or hygiene product; or the pharmaceutical product is a disinfectant or an antiseptic balm.
14. A mannose oligosaccharide composition that has a water solubility of from 20 to 90% measured as a 10 wt % aqueous solution of the composition at 40° C. and that comprises less than 0.1 wt % db of beta-glucan, has a mannose oligosaccharide content of mannose oligosaccharide having a degree of polymerization (DP) of 3 or more that is 30 wt % db or higher, and has a dimannose content of from 10 to 35 wt % db.
15. The composition of claim 14 characterized in that it has having a fructose content of 0.5 to 10 wt % db, a mannose content of 5 to 25 wt % db, and/or a glucose content of 1 to 15 wt % db.
16. A process for making the mannose oligosaccharide composition of claim 1 , comprising:
a) polycondensing mannose by passing the mannose through a microreactor at a temperature of from 180° C. to 240° C. in the presence of an acidifying catalyst to produce manno-oligosaccharide composition, b) optionally neutralising and/or decolorizing the manno-oligosaccharide composition, and c) collecting the manno-oligosaccharide composition.
17. The process according to claim 16 wherein the residence time of mannose in the microreactor during step a) is from 5 to 20 seconds.
