Use of alternan as ingredient for certain foodstuffs
View Patent ↗The invention is directed to the use of an alternan as an ingredient for acidic foodstuffs and to an acidic foodstuff comprising alternan as ingredient. The invention is also directed to the use of alternan as a heat stable ingredient in a foodstuff formulation, and to a foodstuff comprising alternan as ingredient, wherein the foodstuff was subjected to a heating step during its manufacture.
1. A method of manufacturing an acidic foodstuff with prebiotic properties comprising adding alternan-oligosaccharide as ingredient to an acidic foodstuff, wherein the alternan-oligosaccharide has a weight average degree of polymerization DPw of 8 or below as determined by GPC RI, wherein the prebiotic properties are pH stable.
2. The method according to claim 1 , wherein the alternan-oligosaccharide comprises the reaction product of sucrose with an acceptor molecule in the presence of alternansucrase enzyme.
3. The method according to claim 2 , wherein the acceptor molecule is maltose, isomaltose, maltitol, (iso)maltotriose, or methyl-α-D-glucan.
4. The method according to claim 1 , wherein the acidic foodstuff is beverages, fruits, vegetables, canned foodstuffs, bakery products, cake, ready to serve meals, or dairy products.
5. The method according to claim 1 , wherein the acidic foodstuff is subjected to a heating step at a temperature of at least 60° C.
6. The method according to claim 1 , wherein the acidic foodstuff is subjected to a heating step at a temperature of 80-130° C.
7. The method of claim 1 , wherein alternan is added in an amount of 0.1-10 weight-% based on the total weight of the acidic foodstuff.
8. The method of claim 1 , wherein the acidic foodstuff has a pH below 3.
9. The method of claim 1 , wherein the foodstuff is subjected to a heating step at a temperature of 80-90° C. for about 10 minutes.
10. The method of claim 1 , wherein the foodstuff is subjected to a heating step at a temperature of 80-120° C. for 5-3600 seconds.
11. An acidic foodstuff with prebiotic properties comprising alternan-oligosaccharide having a weight average degree of polymerization DPw of 8 or below as determined by GPC RI, wherein the prebiotic properties are pH stable.
12. The acidic foodstuff according to claim 11 , wherein the alternan-oligosaccharide reaction product of sucrose with an acceptor molecule in the presence of alternansucrase enzyme.
13. The acidic foodstuff according to claim 12 , wherein the acceptor molecule is maltose, isomaltose, maltitol, isomaltotriose or methyl-α-D-glucan.
14. The acidic foodstuff according to claim 11 , wherein the acidic foodstuff is beverages, fruits, vegetables, canned foodstuffs, bakery products, cake, ready to serve meals, or dairy products.
15. The acidic foodstuff according to claim 11 , wherein the foodstuff is subjected to a heating step at a temperature of at least 60° C.
16. The acidic foodstuff according to claim 11 , wherein the foodstuff is subjected to a heating step at a temperature of 80-130° C.
17. The acidic foodstuff according to claim 11 , comprising alternan in an amount of 0.1-10 weight-% based on the total weight.
18. The acidic foodstuff according to claim 11 , wherein the acidic foodstuff has a pH below 3.
